Assassin's True Name is Kama (カーマ?), also called Kamadeva (カーマデーヴァ?), the God of Love of Indian mythology. Normally a male deity, he has manifested as a female Pseudo-Servant in the body of Sakura Matou, likely related to her "special characteristic" and another goddess who is also a Pseudo-Servant.
Kama is able to use his sugarcane bow and arrows adorned with flowers to arouse love and lust in whomever he pierces with an arrow. He is famous for the anecdote where he shot the God Shiva, who was focused on his meditation, to get him to notice the feelings of his wife Parvati.
Assassin shows a rather sadistic nature in any of her various forms. While it is less prominent in her Second Acension, she still has those swings of nature at times. Almost as if she, or 'the being' inside of her, has suffered anguish for far too long.
Kamadeva, while open- and an extrovert to how she feels, pertains a sense of forcefulness. Wishing to impose lust, love, or heart-break on those around her. While she will never dabble in those affairs herself unless its a particular Servant or possibily Three people, given her bodies past and relationship with a specific Mother who Holds the Balance of the the World in her hands- the tendancy to force what she cannot have, such as those things upon others shows.
However... Kamadeva's relationship to the Beast III/R almost seems off. Instead of wishing to 'unite' with her counterpart, Kamadeva strays away and looks the other way- this is due to Kamadeva being unable to cope with having a partner of some sort, even if it is not a relationship. Unless. . .
Tokugawa's World-Changing Labyrinth: Inner ChambersEdit
As a result of what happened to the gods in the Indian Lostbelt, the normally suppressed presence of Mara inside Kama become stronger, and she began to turn into a Beast. In order to avoid the Counter Force from detecting the presence of a Beast, she sought a place to hide while her transformation completes. She eventually found the Ooku in Edo Castle upon sensing the dying regrets of Lady Kasuga to want to continue nurturing the Tokugawa. She established a personal chamber inside the Ooku, and invited Tokugaw Iemitsu to indulge in her flesh until he forgot everything. After obtaining his soul, she followed the karmic bonds to everyone in the Ooku, and took their souls. Following that, she took all the souls from the rest of Edo Castle, then everyone's souls from the surrounding area. She then used Kasuga's karmic bonds to the Tokugawa to steal the souls of the Tokugawa Shoguns in the past and future. Afterwards, she used her karmic bonds with Ritsuka to reach into Chaldea. She manipulated Goldolf Musik into disabling Chaldea's protection so she could rayshift everyone in Chaldea into the Ooku, using the Coffins as a medium. Once they rayshifted to the Ooku, Kama froze them while their spiritron avatars were still being established. The exception was Parvati, who resisted, and granted her own Saint Graph to Kasuga's lost soul to keep her in the world.
Using the souls of everyone from Edo Castle and Chaldea, Kama reconstructed the Ooku into a labyrinth that is a six floors deep. She used the souls of the Tokugawa shoguns to serve as the lynchpins for her Ooku. Each floor of her Ooku was designed to be impossible for any human to pass unless they break one of the Five Precepts each floor presents. However any human who breaks them activates a curse that turns them into a Tokugawa. This is connected to the concept of the Ooku being a place for the shogun to indulge in pleasure, thus conceptually, any human who indulges in the pleasures of Kama's Ooku is the shogun. Before the arrival of Chaldea, Goldolf became the first victim of the curse. Kama also connected the Ooku is also connected to her, and since her existence is connected to the concept of the universe, thus it is a recreation of the universe and her body.
Ritsuka, Kiara Sessyoin, and Parvati eventually confront her in a chamber at the end of the first floor. Ritsuka notices she and Parvati are both posessing the same person; Kama explains Parvati possesses the vessel's good side while she possessed her dark side. Parvati then recognizes her and demands to know her connection to the Ooku. Kama replies it shouldn't be strange for a god of love to be connected to a place filled with lust. She also states she didn't create the labyrinth for Parvati. She asks the group if they felt pleasure after clearing the first floor, and reveals she made the automaton maids so efficiently weak to make the group forget the "do not kill" precept. She then wonders who Kiara is since she was outside of her calculations, but she decides to ignore it. She threatens to kill the Chaldea staff and Servants she captured when Ritsuka demands to know what her goal is. She says she may release them if the group makes it to labyrinth's bottom. She then summons a large female ghost, and escapes to await the group at the labyrinth's bottom.
Later, Kama learns of Yagyu Munenori's rescue from her servant, Matsudaira Nobutsuna. When he asks to punish her for his faulure, she tells him the outcome would be the same regardless because defeat is natural for humans. She continues humans cannot perform their duties because they are powerless. She then declares she hates humans yet she will love them. She says her vessel is enveloped with love, as if it's the only thing important to her. She then declares while Parvati loves the pure ones, she will love the imperfect ones, for she is a god of love.
The group later confront her again at the end of the second floor. She ask them why they didn't let the maids guide them since they would've brought them to her. She ignores it though, declaring she already hated them from the beginning. Parvati asks her if she constructed the labyrinth using everyone from Chaldea and Edo Castle as materials to bring her out for the sake of revenge. After Kama laughs off the questions, Parvati asks her again what her goal is. She ignores the question again, and orders a ghost and maids to attack the group.
Kama is confronted once again at the end of the fourth floor. She is dissatisfied the group were able to bypass the puzzles she worked so hard to make. Kiara realizes Kama wants them to reach the Ooku's innermost depths while breaking the precepts. She asks what Kama's goal is, and what her thoughts are. Kama claims her goal is simply to give pleasure in her Ooku. She states going against the strong feeling of not breaking the Five Precepts is particularly satisfying. Because her original conduct isn't bound to such framework, Kama will support every kinds of pleasure, taste, and depravity no matter what they are. She states her body is perfectly suited to such a task, then ages herself into a younger woman. She reveals she created the Ooku Labyrinth so the group could break the Five Precepts and feel great pleasure from it. She tries to tempt Ritsuka into breaking the precept of not stealing, but the others defend them from her. She reveals she has the key to the next floor, and mocks the group for knowing they need to break the precept to advance. After summoning a ghost, Kama becomes strangely angry at Kiara merely talking. She asks for her identity since everyone inside Chaldea except Ritsuka should've been turned into materials. She then assumes Kiara is a Servant whose only talent is to hide. The group then fight her and the ghost, and they surprisingly defeat both of them.
Upon the group reaching the Ooku Labyrinth's innermost chamber, Kasuga demands from Kama where Iemitsu is. Kama removes a pillbox from herself, and reveals it contains Iemitsu's soul. She then reveals the circumstances of how she arrived at the Ooku and recreated it into a labyrinth. Parvati assumes her goal is to destroy humanity, but she corrects that her goal was Ritsuka. She reveals she was able to reach into Chaldea thanks to her karmic bonds with Ritsuka. However Sion Eltnam Sokaris protected Ritsuka against her, so she had them go through the Ooku to reach the innermost chamber to submit to her love. Ritsuka then begins to believe they are a Tokugawa by Kama's power. Nobutsuna reveals there is a curse in Kama's Ooku that activates upon breaking the Five Precepts, and turn one into a Tokugawa. Kama explains that since the Ooku was originally a place where the shogun indulged in pleasures, then conceptually a human who experience those pleasures are the shogun. Kiara realizes Kama's intention wasn't to corrupt them as a whole, but use the corruption to turn Ritsuka into a Tokugawa. Kama reveals Goldolf was the first invite into the Ooku, where he was eventually corrupted into a Tokugawa. She proclaims the Five Precepts are perfect for demonstrating her love, as she will always love those who break them. She declares it to be a proof of her love, but Parvati calls it depravity. Nobutsuna reveals it is impossible to escape Kama's Ooku once someone becomes a Tokugawa. The group try to tell Ritsuka to resist their transformation, but Kama says its futile. She prepares to finish Ritsuka's corruption, and fights the group. Afterwards, she changes her form again, and transform the chamber into a scenery of the universe.
Kama reveals that after she was incinerated by Shiva's third eye, which also burned a hole in the universe, she became bound to the concept of the universe. She then confesses she is now a Demon King; Parvati realizes Kama is now her alternate self, Mara. She wonders how the side of Kama that is Mara was able to emerge so easily. Kama reveals that at present, the interior of her Ooku is identical to her existence as the universe. She explains this means everyone is inside her, and thus they cannot move as they please. She says it's futile to fight against the universe, so everyone should surrender and deprave themselves in her love. Kiara realizes Kama cannot draw out the power of the universe, and Kama admits she cannot in her current vessel. She then reveals she is a Beast, and realizes Kiara is fragment of Beast III/R. Kiara confirms this, and asks why Kama has her sights set on Ritsuka. Kama reveals it is because they defeated Beast III/R while still in larval form, thus she is complete her own transformation. She then changes her form again, and reintroduces herself as Beast III/L. She declares her love is expansive as the universe while Beast III/R (Kiara) is an incarnation of self-love. Kiara realizes being give infinite love from one source would result in the overall concept of love being destroyed. Kama declares she will give everyone her love no matter what happens, and calls Ritsuka to her. Mata Hari tries to get Ritsuka to resist, and the group attempt to fight Kama. Kama easily repels them, and orders Nobutsuna to have Ritsuka drink with Goldolf. Nobutsuna explains in the Ooku's innermost chamber, the conceptually authority of the shogun is strengthened, thus it can manipulate others with mere words. Kama states her body holds the same concept. Nobutsuna tells the group to cease resisting since it's obviously Kama is victorious. Kama is shocked though when Kasuga's slap broke Goldolf's mental conditioning by bringing up some past trauma. She prepares to kill the group, but first asks Kasuga if she's aware she'll face death for striking the Shogun. Kasuga answers she would gladly sacrifice her life if it meant guiding the shogun correctly, which reinstates Kama's hatred of humans. Goldolf tries to fight Kama despite not fully understanding the situation, only understanding she is the enemy. However, his mental conditioning as a Tokugawa since its reversion was only temporarily like Kama said. Kiara then decides to hold Kama back while the others escape. She tells Kama that as the same Beast as her, she cannot allow her love to envelop the universe. Kama refutes her love is enough to fill the universe while Kiara cannot be satisfied unless gather all love for herself. Thus neither of them can ever get along with each other. Kiara admits she lacks her power as a Beast to defeat Kama, and she would rather stop being a Servant. She then unleashes her power as Beast III/R, and she is seemingly destroyed by Kama. Kama declares she will satisfy all with her love once she is fully transforms into a Beast. She tells Nobutsuna they only need to wait, as she still holds everyone hostage.
The group eventually return to Kama's chamber with Anti-Tokugawa magic made from Tokugawa Yoshinobu's pillbox. Kama fights the group to assimilate them into her love. She eventually feels the physical strain of the battle, but she mocks the group for thinking they won. She reveals she wanted them to find Yoshinobu's pillbox because she wanted them to fall into despair when they lost with their only hope. She also reveals she choose the Ooku to complete her transformation into a Beast because she sensed the dying Kasuga still desiring to love the Tokugawa more. She reminds Kasuga on the dream she showed her, where she could continue raising and coddling the Tokugawa like she did with Iemitsu. She reveals how she used Kasuga's karmic bonds with Tokugawa to take their souls from past and future to use as her Ooku's lynchpins. She declares again she will bestow her infinite love to everyone, but Mash and Mata Hari refute that would destroy the concept of loving another. She then triggers Ritsuka's transformation into a Tokugawa, and reveals the Anti-Tokugawa shield can only halt the corruption, not cleanse it. She also reveals she wanted Ritsuka to find and use the pillboxes to further their transformation into a Tokugawa in order to facilitate her transformation. A light then suddenly burst from the cracks in her horns, and she changes her form into one she claims can reach the farthest reaches of the universe. She then removes the platform the group was standing on since she controlled, leaving them floating in space. She then reveals every star in her inner universe is another her. She ponders how long Ritsuka's mind will last in space, and claims they will beg for her to indulge them in her love.
Eventually though, Kasuga disperses the darkness surrounding the group thanks to Scheherazade and Mata Hari modifying her to conceptually rewrite the Ooku. Kama wonders why there is a floor inside her universe, to which Kasuga declares it is her Ooku. Kama angrily asks how the group could reestablish gravity and a supply of oxygen. Sion explains they rewrote the definition of Kama's universe to reestablish gravity, and the mana from Ritsuka's Mystic Code to reestablish oxygen. Kama reminds them though that she interfere with Ritsuka's mind since they still have her corruption inside of then. However, Nobutsuna reveals he plotted with Tenkai to save the Tokugawa from the threat that would destroy them. It also revealed the hanafuda cards the group has been collecting were made from Nobutsuna's organs, whose energy Sion uses to cleanse Ritsuka of Kama's corruption. Nobutsuna is then killed by Yagyu in order retrieve the sword from his body made from the former's soul, which holds the conception of opposing the Tokugawa placed by Tenkai. Kama declares she will satisfy the universe with her love, and says they doesn't need love she doesn't know of. Parvati tells her that is why she is incompatible with humanity because she only doesn't understand the infinite comforting ways of loving others, only understanding of depravity. The group then fight Kama while Yagyu cuts down her other selves. Eventually Kama understands she will only be killed by Yagyu if she continues to hold the property of a Tokugawa. She thus removes the property of a Tokugawa from herself, but Kasuga reveals that also removed her authority over the Ooku. With the Ooku back under her authority, Kasuga returns the Ooku to its original form. After the others attack Kama, she uses her authority over the Ooku, that is akin to conceptual magic, to expel her from it. As Kama continues to be expelled into the air, Parvati tells her that love isn't meant to be given or received one-sidedly. She then strikes her with the symbol of her love of her husand, Trishula Shakti, which is followed by a slash from Yagyu. As Kama is being destroyed, she laments she is always blamed for there not being enough love in the world. She begs to let her give the humans she despises her infinite love before she is finally destroyed.
Kama's normal class is Archer.
