—Kevin as a boy to Wilhelm

Kevin Winnicot was a brilliant Vector Industries First R&D Division scientist, mechanical engineer and computer programmer. Kevin was the creator of KOS-MOS and an integral researcher of the Zohar Project.

He is Shion Uzuki's deceased boyfriend. Like Shion, Kevin is also an orphan whose parents and family were brutally murdered when he was a child by the Gnosis. Kevin became a misanthrope who hates both the Gnosis and the human race.

Kevin was killed approximately two years before the events of Xenosaga Episode I in an accident that involved KOS-MOS' Archetype booting up independently and murdering several members of the team assigned to build her by Vector's Second Division. Shion and Allen Ridgeley survived the attack and decided to continue the project without Kevin, and Shion deeply misses him.

Kevin's body is supposedly buried in a graveyard aboard the Dämmerung, which is the flagship and main colony of Vector Industries. However, there is no evidence to prove that Kevin's body is interred in the graveyard.

Kevin becomes the Red Testament, Wilhelm's right-hand man, and works towards Eternal Recurrence. Shion seems to recognizes his voice when the Testaments appear on the Omega System at the end of Episode II and she later confronts him directly in Episode III where he reveals the truth by unmasking in front of her.



Kevin built the KOS-MOS Archetype.

Kevin is an intelligent genius. Kevin was the mysterious child-genius prodigy lab assistant of the late Dr. Joachim Mizrahi in Labyrinthos, who was briefly mentioned by Dr. Juli Mizrahi in Episode I. Kevin knew just about everything that Mizrahi himself did, so that could have been one reason why Wilhelm sought him out to build KOS-MOS and become a Testament. Kevin apparently enjoys chess, as he is seen playing it with Wilhelm.

Kevin has been known to be quite serious and calm, and he is very subtle and kind to those around him. He speaks in a casual manner, seeming to take things easy. His cold expression hides a deeper meaning behind his feelings.

Memories of Days Past

Memories of Days Past

Kevin tells Shion why he prefers women over men.

Kevin, however, also has some dark emotions secretly festering and hidden inside of him - a massive amount of hate and anger in his heart, as he greatly hates the world and wants to rid the world of the people in it, essentially killing every human in existence. He views humanity with pure shame and disgust and is not proud of humanity. Misanthropic and misandrist in nature, Kevin believes men are power-hungry creatures capable of nothing but destruction and conquest. He hates the Gnosis for taking his family away from him. Kevin also exhibits some psychopathic and sociopathic behavior.


Kevin smiles at Shion.

Kevin loves Shion dearly, and sympathizes with her because she also lost her mother and home planet when she was a child, and both of them became orphans. Kevin wishes to create a new eternal world for his mother and Shion, a peaceful paradise where they can be happy forever. Kevin's mission is to save Shion from her humanity and the human condition, as well as her impending death.

That's right. I have NO attachment to this world. But I CAN'T LOSE SHION!

Because of the loss of the people he cared for as a child, Kevin began to resent the world. He grew a desire to achieve his goals and sought out power to accomplish it. He even shows no sense of fear, as Jin Uzuki prepared to draw his sword against him, or when Jr. attempted to shoot him, probably already due to being physically dead.

When disguised as Roth Mantel, he shows a highly arrogant personality and uncaring attitude, as he looks down on KOS-MOS's performance against Omega Res Novae, and cared less for her maintenance after the fight. He does, however, show a face of disappointment, as he was told to get back to the T-Weapon development and apologized to Shion for not speaking more time together.


Kevin as the Red Testament.

As the Red Testament, Kevin shows with an observing tone, and watches over Shion and the events without much response of what's to come. Luis Virgil considers him to be a scary guy for knowing what's to come, and that he's a "heartless bastard" for how Shion might suffer because of his actions. When Shion meets Joachim, he talks about a man possessed by his narrow-minded ego, and one who brings suffering to all those he comes into contact with, for his words are merely shackles. It is possible Joachim is referring to Kevin. Jr. even considered him as the biggest con he ever met, and Jin and Allen show disdain towards him.

However, though his actions may seem wrong and monstrous to others, Kevin's whole objective was to save Shion from her suffering and to create a new world for her and him for eternity. Nephilim even stated that he is sad and exists for his own atonement, for he wishes for Shion's happiness, further implicating the reasons for his seemingly heinous actions. When Shion was suffering at the hands of Wilhem, Kevin's love for Shion causes him to chop off Wilhelm's arm, and to sacrifice his life to save her and the universe. In the end, he was happy to see Shion smile again during his final moments.

Enneagram analysis Edit

Based on the Enneagram personality classification, he is classified as a type 5 with Wilhelm and Joachim Mizrahi (innovative (or reformist) / analytic / extremist / convention breaker). Historical figures classified as the same type as him include Friedrich Nietzsche, Albert Einstein, and Sigmund Freud. As one can see from this, people of the aforementioned type deeply understand the mechanisms of the world by using unique insight, analysis and ability to think and are people who possess the possibility of discovering new, original patterns. Once that is accomplished, they go down in history as geniuses.

In this type of person, one can see a tendency during infancy to have ambivalent feelings toward the parents. However, there are surprisingly few records of Kevin's childhood, barely any remaining records of his graduation as the top student at Bormeo University in his youth, and after that, records up until his entry into Vector Industries have been erased so verification is impossible.

The motivations for the type 5 are a wish to understand the world, a desire to possess knowledge for that purpose, and a wish to protect oneself from the threat of the world. There is a high possibility that the knowledge he sought through the development of KOS-MOS was directly connected to understanding the world. Conversely, perhaps he developed KOS-MOS because he thought that it would be useful in understanding the world.

While the type of person like him who joins himself to the world through thought could potentially be called a genius, at the same time, there is also the hidden possibility that he could be called a fool. What is the difference between a genius and a fool? They both deviate from the beaten path, that is to say that they are unique. However, the direction of that uniqueness is very different. Geniuses have the power to understand the world through lucidity. On the other hand, fools try to force their own logic on to the world. They are both people who can talk about the world using a fundamental logic, but the former talks about theories based in facts while the latter twists it into facts based on theories. Which kind of uniqueness did Kevin really possess?



Kevin child

Kevin as a little boy.

Kevin was born on planet Michtam, and is therefore a native to the People of Zohar. As a native of Michtam, inheritor of the blood of Abraxas, his lineage is steeped in deep connection to the Zohar, and by extension, Ormus and the Immigrant Fleet.

Kevin's Memory

Kevin's Memory

Kevin's memory of the Gnosis on Michtam.

When he was about 8 years old in 4747, his people and family were threatened by the Gnosis that were unleashed when the Zohar went out of control by the Galaxy Federation. The rest of his family were killed in the process, and only him and his mother managed to get to the spaceport to escape. However, his mother stayed behind and gave him her pendent. Confused and scared, his mother locked him in the escape pod, and he didn't want to lose her. His mother placed her hand on the glass, and she began to transform into a Gnosis, much to Kevin's horror. His mother smiled to him in fear and sadness, and the escape pod shot him into space to avoid the destruction of Michtam.

Some time afterwards, he was found by a salvage vessel and questioned on where he came from, but the trauma and shock greatly affected him from speaking. Kevin was placed in an orphanage and eventually adopted by foster parents thanks to his keen intelligence, and given the surname Winnicot. It is also unknown if Kevin is his true given name, but it seems likely because when Kevin was rescued, "Kevin" was the only thing he could say.

Eternal Circle

Eternal Circle

Wilhelm tells Kevin how to end the world.

At these events, Kevin was confronted by Wilhelm about the current situation of the universe. Wilhelm told him that, because of a certain phenomena, the universe is slowly but surely heading towards destruction. He continued to say that no one can stop it, even if they had the power of God. Now realizing that the universe will soon die, Wilhelm reassured him not to despair, for there is one way to save the universe, and Kevin wondered if it is "Eternal Recurrence". Wilhelm stated that, if they are destined to die, then they shall stop their history at a certain point and restart it, and shall repeat that process eternally. Wilhelm then questioned Kevin what does he feel about their world, and what to do with this world that drove him into the pit of despair. After much thought, Kevin replied that he hates the world, and that a universe like this is better off gone. He then finished by saying that he can then live in a new universe with his mother and those he held so dear to him. Wilhelm told him that that was a good answer, and that he should accomplish that dream. Wilhelm then agreed with his choice and welcomed to aid him in his goal.

Wilhelm took advantage of such childish wishes. Sweet-talking as if those wishes could come true, he encouraged Kevin to work towards Eternal Recurrence. Kevin had extraordinary talent, and he also possessed the factor to become Testament. Having received Wilhelm's support, and believing that he could purge this accursed world and recreate a new one, Kevin and Wilhelm developed a relationship and worked for him. However, Eternal Recurrence is something that aims for a complete reiteration. The "new world" that Kevin was searching for, was merely something that would once again repeat for him a life that curses the world for the loss of his mother.

Miltia (U-TIC Organization)Edit


Kevin (age 14)

After some point in a few years, Kevin went to Bormeo University at age 14 (and would later graduate at 15, further showing his brilliance at such an age.) While at the C.S.R.C. during his studies at university, Kevin transferred along with Joachim to the U-TIC Organization. Kevin then joined the Zohar research team with Joachim Mizrahi at U-TIC's Labyrinthos on Miltia, therefore becoming his assistant by Wilhelm's command. He was even ordered by Wilhelm to watch over Shion, who is the key to the plot of the Eternal Recurrence. Kevin even created a horde of the 27-Series Asura that have superior combat abilities, but are yet to be stable. He even completed making the initial designs and blueprints of an anti-Gnosis battle android, the ideal android being KOS-MOS. Kevin being Mizrahi's assistant explains his knowledge of Realians and the Hilbert Effect.

During the Miltian Conflict, which was sparked when the U-TIC Organization refused to hand over Joachim to the Federation, Febronia, a transgenic-type Realian owned by the Uzuki family and Shion's nanny, was out getting some flowers and found a critically injured Luis Virgil. Febronia brought Virgil to Kevin and Shion at the church nearby and, though he was against saving the life of an enemy soldier, he agreed to save Virgil's life. However, because nanomachine treatment wasn't enough and the stem cell germination can't keep up with the damage that was inflicted, Kevin grunted that it was hopeless without a organ transplant. Out of selflessness, Febronia requested Kevin to transplant her organs. Kevin was against it and stated that they can't risk a valuable Realian for the life of one soldier. Febronia reassured him that since she's a transgenic-type, their cells should have an affinity to each other. Seeing that Febronia had made her mind up, he complied and went on with the procedure. After succeeding in the surgery, Kevin took Febronia to Labyrinthos to regenerate, and for Virgil to stay in the church.

Inside Labyrinthos, Margulis and Sellers commented that Kevin's idea to make Joachim Mizrahi into a scapegoat for the Miltian Conflict is quite impressive at best, and that he is quite a tactician for his age. Margulis and Sellers then continued with the plan that has been presented to them, and that they'll have their fleets ready to depart from Miltia when it has been settled. Sellers even had Kevin try to get some information from him about the Y-Data, and is waiting to hear the results of his success on that behalf. It was this time that Kevin's discussion with Joachim was recorded in a single camera within Labyrinthos, and was under investigation of who the boy was by the Subcommittee.

Shion's Flowers and Kevin

Shion's Flowers and Kevin

Shion and Kevin outside Labyrinthos.

Much later, Kevin spotted Shion planting flowers by Labyrinthos, and expressed that he was surprised to see that they can still grow around the area, and that they probably haven't died yet. Shion assured that they won't die, since she places seeds and gave them fertilizer. Kevin then stated that there's no guarantee that they won't die in the future. He continued to say that he doesn't understand it, but wondered why she planted them here instead of the rear garden. Shion explained that they would too far from her mom's room, and that this spot by Labyrinthos would be much closer, and so that her dad can see them too. Kevin, however, chides that he can't see Supervisor Uzuki having any interest in flowers, which Shion looks to him with a look and grunt of disagreement.


Kevin talks about how killing is part of human nature and how humans will never stop killing animals and each other.

Kevin then told her how he believed the world works: humans must conquer, destroy, kill and feed on other organisms to live, and that it's the "basic function of an organic being." He then told Shion that there is no point in what she's doing. Shion doesn't believe that to be true, and she says that when her flowers bloom, everyone will be happy, including her dad. Kevin wouldn't bet on that, and Shion replied that Febronia said so too. Kevin continued to not get the idea and Shion continued to help the plants. Kevin then stared at Shion for a moment, as he remembered that he had been ordered by Wilhelm to keep tabs on her safety, yet felt like he was starting to know her more than needed.


Kevin and Shion watering flowers.

Shion, not waiting any longer, told Kevin that, if he's just going to sit around, he should give her a hand on watering the flowers. Kevin, taken by surprise at such a request, argued on why he should do that. Shion then had the water pot for the plants in his face and replied that he's not doing anything, so he should help. She continued to push him into assisting her, and it resulted in him having the water splash on himself. He whined that it was cold, and blamed her for it, but Shion merely laughed. Kevin, feeling really irritated, decided to help out, and asked her on where to water them. Shion then gave him several spots to water, but he was being to rough with it. Shion told him to be more careful, otherwise he'll hurt them. Kevin complained why would he hurt them, since they're just flowers.


Kevin and Shion watering flowers.

Shion took the waterpot to show him how it's done. Seeing Shion watering the plants gently, Kevin saw her with joy of the flowers looking ever more beautiful, and Kevin still looked to her in confusion. Suou Uzuki then called Shion by the front door of Labyrinthos, presumably to see her mother's condition. Shion then went to go and asked Kevin to continue the work in her place. Kevin, before he could make a complaint, just dismissed the issue and continued watering the flowers. As he resumed the work, Kevin then smiled for the first time at this and began to understand Shion better.

Kevin, Margulis and Suou.

Kevin then appears with Margulis and Suou Uzuki at the location of Proto Omega and the Zohar, discussing the events revolving the Conflict and the importance of the relics of God. Though this was in Sergius XVII's jurisdiction, Margulis revealed that Sergius was only interested in Proto Omega, and that it was Lord Heinlein's work in all this. When the three behold the Zohar within Proto Omega, Suou had to remind them to be extra careful when the Zohar experiment, for Febronia is still regenerating. Kevin stated that she's still disposable, and that they can always create another. Margulis asked Kevin why he insist on using Realians, instead of relying on the patients for the experiment. Kevin replied that it is because of fear, which he said that Realians feel no fear. Thus, it was the reason why they can use them. Margulis chuckled and confirmed that he had heard that Realians also feel fear like the humans. Kevin continued to say that all things fear their own deaths, but Realians are strongly connected at the subconscious level. They never reject each other, and, even if they physical bodies vanish, they are still connected as one. Kevin then explained that it was the reason why they are different from people.

Suou then explained that, in order to activate the Zohar, they must use Lemegeton to convey human will from the Vessels of Anima via the U.M.N. However, this would also cause direct contact with U-DO which invokes primal fear into human beings. He continues and explains that humans reject others, and those who are rejected are overcome with the fear of isolation. That fear becomes even worse than death, since humans will have nowhere to go. Suou then revealed that the Lemegeton program would be able to further help their plans, but it is based on incomplete data. Due to that deficiency, they have already lost one transgenic-type unit. If they had the original source of Lemegeton, then things would have been different. Kevin then stated that the Realian consciousness inevitably suffers stress, since it acts as a wall to suppress the human fear of U-DO, and that they need to make sure that the Zohar activation happens at the exact time as the Miltian Conflict begins. Suou also unveiled that a certain company is aiding them as well, but it happens to be unofficial. Margulis assumes it to be Vector Industries, and questions if it's safe. Suou just boldly said that all that matters are results, seeing as that's all business cares about. However, if Sergius were to find out about Vector's involvement, he's not going to be happy. Margulis then begins to leave and replied that Sergius won't ever know, and that they shall have a new master soon enough. As Suou and Kevin begin to leave the hangar room with Margulis, Suou warned the commander to be careful about saying that kind of speech, as the walls have ears everywhere.

Xenosaga III HD Cutscene 175 - Kevin and Suou (Labyrinthos) - ENGLISH

Kevin being confronted by Suou.

Some time later, Kevin stared at the 27-Series Asuras in silence, but could possibly be deeply concerned on how their unleashed rampage would cause to Shion and the others. But before he could continue his work on them, Suou barged into his private room to confront him about the weapons in containment. Kevin told him if there was something he wated to talk about, then it would have to wait later. But Suou objected about using the 27-Series Asura, as they were solely for experimental use. He clarifies that they are still unstable, and if they let them go to the battlefield they won't be able to reign them in. But Kevin dismissed the issue and said that their combat abilities will be expected, for that was all that's needed. But Suou object that they can't distinguish between an enemy and an ally, thus he questions Kevin if he's planning to use a weapon that can only cause indiscriminate destruction.

Kevin stated that when the Song of Nephilim goes into operation, everything will be resolved by the awakening of the Zohar. Suou becomes concerned about the Song of Nephilim that was born from the Lemegeton translation, and urges Kevin to reconsider his choice, and that there's still time to stop the 27-Series and the Song. Kevin, however, remained dissuaded and said that there is no other way to activate the Zohar, and the descant troops have already made their way into the city of Miltia. He confirms that if they act now with the Song and the 27-Series Asura, then all of their efforts would have been for nothing. Kevin then asked that wasn't this why he betrayed the Federation by defecting to U-TIC, and Suou hesitantly denied it. But Kevin questioned on the matter, and even revealed that Suou sacrificed his own wife in order to save his daughter, thus he asks him on why would he hesitate now. Suou told him that he couldn't possibly understand, and painfully admitted that he had no choice. Kevin then grinned, crossed his arms, and says that what he just said is right. Because, for the realization of their ideals, there is no other choice. Kevin finally pointed out that Miltia's sacrifice cannot be avoided, and Suou grunts in frustration.

Miltian ConflictEdit

Crushed Flowerbed

Crushed Flowerbed

Shion mourning her dead flowers.

When the third descent operation began and the U.R.T.V.s were deployed, initiating the full scale Miltian Conflict war, Kevin arrived to where Shion was crying over the battered flowers, Kevin felt a sense of regret. Kevin told her that there was no point in growing them, as flowers won't make anyone happy. Shion objected that they will, and was going to plant more to show everyone. Kevin, remaining dissuaded, said that they'll just get trampled again. Kevin felt that it was futile and pointless to put so much energy, time, work and effort into something that's probably going to be inevitably be trampled and ruined by humans sooner or later. When Shion began to leave, Kevin questioned her where she was going, which Shion replied that she was going to get more seed from Febronia.

Xenosaga III HD Cutscene 183 - Kevin's Resolve (Outside Labyrinthos) - ENGLISH

Xenosaga III HD Cutscene 183 - Kevin's Resolve (Outside Labyrinthos) - ENGLISH

Kevin's resolve in a world gone to hell.

After Shion left, Kevin looked at the ruined flowers, and thought for several moments. After much thought, and seeing how this world has gone into chaos and devolved into hell and descended into madness, Kevin told himself that no one has the ability to lead others to the truth, as their powers are too limited. Kevin then saw that there was still one flower left unharmed, and his face was filled with resolve. He took the flower in his hand, with only several petals, and declared that only those who possess divine power can accomplish that: leading others to the truth. These petals from the flowers he picked were then put into the pendent he was given from his mother, and then gave to Shion. Because he loved Shion, the petals he had inside the pendent were proof of his feelings and resolve.

Kevin's foster parents were killed in the Miltian Conflict by Realians. It is unknown how Kevin survived the Miltian Conflict, but given that he was technically U-TIC personal, he was would have presumably been allowed to use the Song of Nephilim as a life boat.

Vector IndustriesEdit


Kevin in his Vector Industries uniform.

After the Miltian Conflict, Kevin moved to Second Miltia and joined Vector with KOS-MOS' fundamental theory.

Kevin was instrumental in drafting Shion into First Division. She was originally going into Third Division, but after Kevin read a thesis she had previously written he pulled some strings and got her assigned to the First Division and the KOS-MOS development project.

E.S. Dinah is an E.S. unit which started development about the same time as the KOS-MOS project and was created by Kevin to help KOS-MOS in her task as a supplementary weapon. Like every other E.S., it is equipped with a Vessel of Anima.

Kevin wanted KOS-MOS to have a female form as opposed to a male form because he wanted KOS-MOS to symbolize hope and healing, as well as a creator and protector. A female form would also be more suitable for Mary Magdalene.

At first, Kevin thought to use Shion as the Maiden of Mary Magdalene who is a necessary factor for Wilhelm's orchestration of Eternal Recurrence. But eventually, his heart had become captivated by her. Kevin began to think that he would use the power of Testament not for the sake of Eternal Recurrence, but for the sake of constructing an eternal world with Shion.

Kevin and Shion talk about the Gnosis.

While they worked together on the KOS-MOS Archetype, Shion fell in love with Kevin and they began dating. During this period, she acquired her trademark round holographic glasses as a gift from Kevin in order to control her congenital unique sense that has allowed her to see into imaginary space since early childhood, as well as Kevin's mother's necklace.

Death Edit

Xenosaga Episode I HD Cutscene 056 - The KOS-MOS Incident - ENGLISH

Xenosaga Episode I HD Cutscene 056 - The KOS-MOS Incident - ENGLISH

Kevin and Andrew Cherenkov.

Kevin decided that the time to become a Testament had finally come and that in order to obtain power, it was necessary he cast aside his physical body. Kevin chose to die by suicide by the KOS-MOS Archetype. Kevin was the shrouded man who handed the access device to Andrew Cherenkov before the assault of the Vector lab while KOS-MOS was still in her prototype form. Kevin would also have unique access to such codes as would be necessary to capture KOS-MOS, making him all the more suspect as the man who seemingly betrayed KOS-MOS to the U-TIC Organization.


Shion cradles Kevin as he bleeds to death.

This rosy period ended with Kevin's death at the hands of the KOS-MOS Archetype on planet Carioca, as he tried to defend Shion from it after its activation by U-TIC. However, Kevin was brutally killed when the Archetype stabbed Kevin through his torso. KOS-MOS going berserk and Kevin's death were all planned by Kevin. Shion became Chief Engineer of the KOS-MOS Project General Operation System Research Center in the Vector Industries First R&D Division, Allen became her assistant, and Kevin became a Testament.

Shion was devastated by his death and KOS-MOS, who was already a very large part of her life, became the most important person in her eyes. Shion worked endlessly to complete her, which Kevin expected her to do.

Eventually, through her dedication to the project, Shion began resonating with Mary Magdalene's consciousness inside of herself as she was the previous incarnation of the Maiden of Mary.

Xenosaga Episode I: Der Wille zur Macht Edit


Kevin and Shion in a flashback.

Kevin is seen in three of Shion's flashbacks.

In the first flashback, Kevin gives Shion a drink and he wonders what to say to KOS-MOS when she awakens. Shion suggests a simple "good morning", and he agrees to that.[1]

In the second flashback, Kevin wonders if KOS-MOS has a heart and emotions.[2]

In the third flashback, Shion remembers Kevin's death.[3]

Wilhelm orders the Red Testament to "gather the necessary factors" and "wait for the other one to awaken."

Xenosaga Episode II: Jenseits von Gut und Böse Edit


Kevin and Shion in a flashback.

Kevin appears in a single flashback near the beginning of the game when Shion returns to Vector Industries. In it, he tells Shion about how he hopes KOS-MOS will be more than just some wanton instrument of destruction. He also hopes the future that she builds will be one swept clean of differences - an ideal world free of destruction or slaughter.[4]

Shion seems to recognize his voice when the Testaments appear on the Omega System. Kevin pilots E.S. Judah.

Xenosaga Episode III: Also sprach Zarathustra Edit

Kevin returns as Roth Mantel, developer of T-elos. He meets Shion and Allen at the CAT Testing Grounds on Fifth Jerusalem. He appears in the KOS-MOS maintenance room and reveals that the S.O.C.E. has decided to dispose of KOS-MOS, in favor of pouring their resources into T-elos' development.

On Rennes-le-Château, Roth Mantel appears and reveals himself as the Red Testament. During a fight between T-elos and KOS-MOS in which KOS-MOS is almost destroyed, Shion's pendant emitted a bright light, engulfing all of Rennes-le-Château.

Red Testament (Labyrinthos)

The Red Testament reveals himself to Shion.

When Shion's party returns to "Miltia", a younger Kevin appears, working for Joachim Mizrahi. Later, when Shions hears her mother's name, Aoi, on an announcement system, she runs back to Labyrinthos. There, the Red Testament confronts her and unmasks, revealing himself as Kevin, much to her disbelief and confusion. Shion is then arrested by U-TIC officers. She is interrogated by the younger Kevin, Margulis and Suou. Kevin pressured Shion to speak about the Vessels of Anima and revealed he knew she was using them as mobile reactors.

KOS-MOS Escapes

KOS-MOS Escapes

Kevin returns to Shion after her parents die.

During the Miltian Conflict, after Shion relived the traumatic memories of her parent's deaths, the Red Testament appeared at this moment together with T-elos and revealed himself as Kevin Winnicot. Kevin began to explain how Shion, like her mother, has the ability to "talk" with U-DO. By staying with KOS-MOS who draws power from the Zohar, she is slowly and surely losing her life. Filled with love and misery, Shion attempted to leave with Kevin, but was stopped by Jin and the team. The team escaped to the Elsa and returned back to normal time.

Shion Joins Kevin

Shion joins Kevin on Michtam.

On Michtam, Shion learned the truth about of her identity as the reincarnation of the Maiden of Mary and that KOS-MOS contained the spirit of Mary Magdalene. After KOS-MOS awakened, Shion and her group met Kevin. Jin, Allen and everyone else tried to prevent Shion from joining Kevin but were unsuccessful. Shion decided to go to his side, prompting a fight between Shion and Kevin versus her friends.

Shion Leaves Kevin

Shion Leaves Kevin

Kevin is heartbroken when Shion leaves him.

Shion looked worried while Kevin proceeded to torture Allen despite his failure. KOS-MOS then saved Allen's life and Shion decided to leave Kevin when she realized that Kevin was willing to hurt her friends and could not be happy. Kevin, unwilling to let Shion go, decided to eliminate her friends, thus he transformed and prepared to battle.

Despite using all the powers of a Testament, Kevin lost the fight and questioned if this was the result Shion desired. Kevin then told her that she was confused, and is unable to make calm decisions about where she stood. Kevin proceeded to continue the fight with her friends, but Shion got in between him and her friends, and pleaded to Kevin to stop. Kevin told her that he didn't want to hurt her either, and asked her in frustration on why she can't seem to understand his feelings. Wilhelm, having waited long enough, told Kevin to stand down since his time was up. Kevin grunted in anger and left to regroup with Wilhelm, and Shion tried to stop him from leaving.

Zarathustra is then later unleashed, and seizing his opportunity, Kevin lunges his arm through Wilhelm, in an attempt to control and suppress Zarathustra through Wilhelm (who is the self proclaimed "operator" of Zarathustra), although the end result would end in both Wilhelm's and Kevin's death. Before this, chaos told Wilhelm that he believes mankind has the will to change that future and prevent the universe from destruction. Kevin urges Shion and her team to stop Zarathustra. The party then attacks Zarathustra, and maintains it.

Kevin apologized for his behavior, tells Shion that he was happy to see her smile again, and says the world is waiting for her. Kevin then disappeared. Whether or not Kevin's spirit and consciousness (like Jin's) travels with Nephilim to Lost Jerusalem is uncertain.

Shion relaxing with Kevin after sex.

Kevin was Shion's boss and lover before the events surrounding KOS-MOS's awakening. He attempted to manipulate her at first for Wilhelm's plan, but fell in love with her and were engaged to be married.


Kevin sacrifices his life to protect Shion from the berserk KOS-MOS Archetype.

He died as a human when the KOS-MOS Archetype was risen by U-TIC and his death devastated Shion. When she replaced him as the leader of the KOS-MOS project, Shion became obsessed with finishing her for Kevin. He was risen by Wilhem as the Red Testament and he became the leader of Vector's right-hand man. Kevin still held feelings for Shion and persuaded her to leave her friends in order to join him.

He died again as a Testament when he attempted to stop the awakening of Zarathustra and this saddened Shion, though she had already realized that he was evil, but did all this to save her life. They exchange their feelings from the broken pendent that KOS-MOS destroyed, and it is revealed to contain flower petals from the garden Shion made. The exact flower petals that shows how much he truly loves her, even to the very end. As Kevin bids her farewell with a smile and passes on to the other side with peace in his heart, Shion now looks forward to the future and bids him farewell with renewed resolve. Despite all the pain and suffering within the story that he may have caused, Kevin's undying love for Shion, and Shion's discovery of his determination to sacrifice himself for her, helped her become stronger and looking forward to saving the universe from destruction.

  • "The universe is going to die?"
  • "Placing one against another and fighting is a defining aspect of human beings. Resisting it is unnatural."
  • "No one has the ability to lead others to the truth. Our powers are too limited. Only those who possess divine power can accomplish that."
  • "Everything exists for a reason. If the Gnosis represents a truth we haven't known before, then I want to know what that is. I think that may actually be the shortcut to saving this universe."
  • "I was the only one that survived. Sometimes, I don't know if what I'm doing is to atone for not being able to do anything, or to take revenge against those who took everything from me. But I can say that even if the universe desires otherwise, she is our hope."
  • "The path I'm walking may be a mistake. I don't know for sure. Will you walk down this path with me?"
  • "Tomorrow, she's finally going to wake up. I'm looking forward to seeing her come to life, but... I have no idea what to say to her when she wakes up. It's been bothering me... I'm just being weird, huh?"
  • "I want to believe that KOS-MOS will be more than just some wanton instrument of destruction. I hope the future that she builds will be one swept clean of our differences. An ideal world free of destruction or slaughter."
  • "Men are creatures capable of nothing but destruction and conquest."
  • "Please listen, Shion... I don't want... to lose you again."
  • "I promise you that I'll never leave you again. We'll always be together."
  • "I know. You're scared, aren't you? You don't know what you should do, or even who you are. You don't know where you belong. You don't need to be afraid any longer. I'll give you those answers. I once felt the same way as you do. When this planet was destroyed, I lost everything, even my sense of who I was."
  • "In order to obtain power, it was necessary to cast aside my physical body."
  • "Shion, I'm sorry about what I've done to you. But I want you to understand. To save you and the world, I had no choice. With this power, I can free you from the terror of death. I can spend eternity with you. I want to save you, Shion."
  • "You'd let your own sister die? What a heartless brother." (to Jin)
  • "Shion, please listen to me. Shion! An empty life is more terrifying than death! Shion, come back to me! Now you learn of death!"
  • "Eternal rest for tainted souls!"
  • "DIE!"
  • "PERISH!"
  • "You refuse to accept it? Do I need to request your approval? The fact is, she will die. Are you saying that you will accept Shion's death? That you will abandon Shion to her suffering?"
  • "Pathetic. If the world could be saved through passion, all of this would have been unnecessary. Now, come, Shion. You've done more than enough. You don't need to sacrifice yourself anymore. It's all right to think about your own happiness. You know, don't you? That there's no place for you there."
  • "You still don't understand? The cries of the powerless is what's meaningless. Your pathetic voice will reach no one."
  • "What's wrong? Weren't you going to stand firm? Look at you. You're pathetic. You think you can save Shion? You really are pathetic, Allen. How does it feel to be pitied by the one you love? Do you really want Shion's sympathy that much?"
  • "I see. But I... will not hand you over voluntarily. Instead I will... eliminate those who confuse you!"
  • "Shion, you're confused. You're unable to make calm decisions about where you stand. Shion, I don't want to hurt you, either. Why can't you understand my feelings?!"
  • "That's right. I have no attachment to this world. But I cannot lose Shion!"
  • "That's right. You'll... be fine now. I'm glad I was able to see you smile again. Hang in there. The world is waiting for you." (final words to Shion)


  • Kevin possessed uncommon knowledge about Realians as well. When Shion, who was carrying out the mental care of the Realians in the Woglinde's Realian adjustment room, said "This is all second-hand information from my superior" (or "I'm just making the most of what my mentor taught me" in the English version), that superior/mentor she spoke of was Kevin. The mental care of Realians is said to be difficult even for specialists. The structure of Realians' brains is extremely close to that of humans and they are even endowed with intelligence and feelings. In addition, KOS-MOS' is also a faithful reproduction of a human brain. Where did Kevin, who had knowledge of both Realians' brains and KOS-MOS' brain, come to gain such knowledge? Formerly there was Dr. Joachim Mizrahi, known as the leading authority in the world on brain research, and the Mizrahi Cerebral Sciences Research Center, but there is no information to verify whether or not Kevin was affiliated with either one. This is due to the fact that when the Mizrahi Cerebral Sciences Research Center became the U-TIC Organization and that same organization turned into the present day armed group, data from the past was lost. However, the time period in which Kevin was graduating Bormeo University as the youngest top student ever was before the start of the U-TIC Organization and it is only natural that an excellent student like Kevin would enter into the Mizrahi Cerebral Sciences Research Center. Also, when one assumes this, it is possible to explain the environment in which Kevin gained the knowledge about brains that he had.
  • In the Japanese version, Shion calls Kevin "Kevin-senpai", adding to their relationship, and how Shion looked up to Shion for guidance in her life.[5]
  • Kevin's alias, "Roth Mantel", is German for "red coat" or "red cloak" in English.
  • Kevin has been confused to be Shion's "fiancé", however, the in-game databases only refer to Kevin as her "boyfriend" and "lover". There is no proof that Shion and Kevin were going to be married. This confusion may occur because the scene in Episode III in which Kevin gives Shion his mother's pendant and they kiss is similar to a proposal/engagement.

Shion and Kevin.

  • There are rumors that Kevin had a sister who died during Michtam's destruction. However, she doesn't seem to be referenced in any material in the official games, guides, or databases. It seems that she may have been reference in Xenosaga I & II, however, this game has never released in English so it is difficult to confirm this.
  • Kevin is the contrast of Shion. Both Shion and Kevin have painful, tragic childhoods and dead parents. Kevin's wish is to kill and reset humanity, and give up on humanity's existence. Shion's wish, at the end of Episode III, is to allow humanity continue, don't give up on it, and do whatever she can to fix and change and improve it.

Kevin's grave has Latin on it.

  • Kevin's grave has "ecce universa terra coram te est recede a me obsecro" on it. The Latin text is a quote from the Bible. They are Abram's words to Lot in Genesis 13:9-11. This roughly translates to, Abram (later, Abraham) telling his nephew Lot:
    • "Isn't the whole land in front of you? There is plenty of land available for you to choose from. Choose any part of the land you want. A vast land is out there and available to you. It is time for us to go our separate ways."
    • This could be interpreted in many ways, but there is a comparison between Lot and Kevin. Kevin may Lot's reincarnation, much like how Shion is the reincarnation of Mary Magdalene's maiden. It may be interpreted as it is time for Lot to make his own choice in life, much like Kevin chose to die.

Shion and Kevin boss fight. He has 12,000 HP in the first fight and 52,000 HP in the second.

  • If Jin is in the battle party during his boss fight, Kevin will specifically address Jin and call him a heartless brother: "You'd let your own sister die? What a heartless brother."[6]
  • The player can steal Shion's White Shirt outfit from Kevin during the first boss fight (the player can steal Shion's U-TIC Research Uniform from Shion).
  • Kevin shares a common ground with Karellen and Lacan (who would eventually transform into Grahf) from Xenogears:
    • Lacan: Lacan sought out power from his heartbreaking memory of Sophia's death. Kevin lost his mother on Michtam, and was devastated by it and sought power as a result.
    • Grahf: Grahf, known as the "Seeker of Power", and wishes to merge with Deus to destroy all life. Kevin's plan was to destroy the universe with Zarathustra to return everything back to the beginning by Wilhelm.
    • Karellen: Karellen was saddened by Sophia's death, and wanted to create "God" for a world without loss and pain for others. Kevin wished to create a world perfect for him and Shion without them ever being pained or separated again. When Karellen passed on, he accepted his fate to God and passed away in light with angelic wings. When Kevin died to end Wilhelm, he spoke to Shion one last time and passed on in a shining ray of light with a smile.
