Unlock Description Translation
Default 覚者の敵対者。




The antagonist of Buddha.

The saint that appeared in the Deep Sea Virtual Paradise, SE.RA.PH.
The one who employed the rare qualities as a messiah that she possessed only for her own sake, metamorphosing into something not-human.
Her pledge, her hope was put to an end when she had just barely reached the shore.
Kiara herself vanished at that time, but maybe due changing her way of thinking upon death, she left a portion of her power behind as an Alterego and accepted for it to be summoned by Chaldea in the future.

"It’s fine right, Chaldea.
To throw oneself into battle at many ages, many places...
I would also like to have a taste of that myself."

or so she says with a reserved smile. But, of course, her real intentions are nothing like “for the sake of humanity”.
One must be cautious, for even after becoming somewhat more mellow, her nature has not changed at all.

Bond 1 身長/体重:166cm・53kg?

出典:『Fate/EXTRA CCC』
属性:混沌・悪  性別:女性

Height/Weight: 166cm ・ 53kg?

Source: Fate/EXTRA CCC
Origin: SE.RA.PH
Alignment: Chaotic ・ Evil
Gender: Female
"As a woman, I would wish that you went easy in regards to the height of my body.
Please, no matter what happens, do not line me up with a childish fairy-tale writer, all right?"

Bond 2 性格は弱気、内向的、能動的。



Her personality is introverted, timid and active.

A graceful and elegant woman, but by no means straight-laced.
Possessing the nonchalance and tolerance to respond to any joke with an smile, her personality is warm and tender.
Despite showing a chaste sense of values and speech, her words sometimes have a strange eroticism.
Gentle yet assertive. Vigorous despite feeble-looking. Empathetic and filled with compassion.
She possess the thoughtfulness to perceive the truth of things, read the hearts of all people and properly understand their standpoint・anguish.

Her true nature is that of a bewitching bodhisattva who did nothing but throughly investigate narcissism and pleasure until she reached nirvana.
A tender sadist and a hard masochist.
Although speaks from the bottom of her heart that she “loves humans”, she is a monster of narcissism that speaks of morals simply “for her own sake”, speaks of the preciousness of life simply “for her own sake” and also protects the world simply “for her own sake”.

Bond 3 キアラにとって「人間」とは自分だけであり、



For Kiara, she alone is “human” and all other humans are merely beasts or insects that had taken human form.

As such, despite directing her love towards the whole outside world, its final destination is something “for her own sake”.

A pervert not only in regards to sexual pleasure: she consumes all surrounding lives “for her own sake” and feels the greatest sensuality in seeing them self-destruct.
Because of that, she thinks that it is OK to be raped or killed.
Also thinks that it is OK to rape or kill.
At any rate, it is fine so long as the life of that human ends by means of the female body called “Sessyoin Kiara”.
Kiara will attentively watch that image and simply smile while feeling ecstasy. That state is like a bodhisattva who watches over people's lives in pity.
...even if that is a path towards destruction for those who are trifled with while on the palm of her hand, this process is undoubtedly a heavenly pleasure.

Bond 4 『快楽天・胎蔵曼荼羅』

ランク:EX 種別:対人宝具 最大捕捉:七騎

Pleasure Heaven - The Womb Realm Mandala

Rank: EX
Type: Anti-Unit
Maximum Targets: Seven Knights
Amitābha Amidala - Heaven's Hole.
An Anti-Anthropic Principle, or maybe Anti-Grand Noble Phantasm.
A Noble Phantasm for Beast III exclusive-use, which breeds a virtually infinite amount of demon pillars inside her body.
The inside of her body has already turned into a single universe - the Sukhavati.
Those brought inside here will disappear from reality, have their ego released by preaching and their intellect melted.
No matter what kind of robust body, defensive armor one might have, they are meaningless inside Kiara’s body; this just renders them powerless like a life that has just being born and forced to reach nirvana. Beast III is a “hole” in itself that was formed in reality, but those who fall on said hole savor the greatest pleasure just before being annihilated and are absorbed by Kiara while in ecstasy.
Depending on how you look at it, this fate of being released from reality - which is a world of suffering - can probably be called salvation.

Bond 5 ○単独顕現:E




Independent Manifestation: E

This has been sealed by herself upon becoming an Alterego.
What people call restraining oneself. That being said, she is still endowed with the “instant-kill resistance” and “fascination resistance” possessed by Independent Manifestation.

Clairvoyance (Beast): D
The rank of Clairvoyance is low, so she cannot look into the far away. However, she can see through the desires and truths of the humans in front of her, exposing them.
...if it was just that, this would be a skill of a wise man, but Kiara herself end up getting excited by exposing the animal nature・truth of the opponent, acquiring overwhelming joy. Just like a poisonous snake that licks her lips before a prey.

Thesis of the Still Heart: A
A medical software that Sessyoin Kiara developed.
A virtual formula created for the purpose of mental care, it measure the sediments・disturbances of the mind and stabilizes the mind by physically picking it out.
Originally created in order to produce a map of the patient’s mind and help understand it.

Clear Epilogue : Time Sculpting Palladion (2/2)
Extra 『FGO』では海上油田基地セラフィックスのスタッフとして登場。




She appears in “FGO” as a staff of the offshore oil platform Seraphix.

While she was exasperated upon being allocated to the Western church despite being a Buddhist, she wholeheartedly endeavored in her professional duties.
At this point of time Kiara was unmistakably a saint. But on January 2017, having escaped alive from the Temporal Temple, the demon pillar Zepar ended up hijacking her body and turning her into a puppet in order to rule over the Seraphix as a demon underling.

...or that was the intention, but at some point Zepar itself was dominated by Kiara, who turned into a fiend that could freely manipulate demon pillars and in the end metamorphosed into a Beast.
Kiara discovered her most excellent self among the many parallel worlds and fused with it.
Bringing up the imaginary phenomena of the CCC world to the FGO world, she turned her own body into a SE.RA.PH and grew by making Servants into source of nutrients.
Ultimately, she schemed to become one with the Earth, but her climax was obstructed by Meltlilith, BB, Passionlip and Chaldea’s Master.

She became more obedient by turning into an Alterego.
To be specific, she vowed to herself to lead a continent life until her contract ends.
Therefore, even though her personality has not changed, she no longer thinks of preying on everyone she lays eyes upon.
Her attitude towards the Master is just like the enemy of Buddha - the Mara.
Even while awaiting in anticipation for the moment when the Master will lose to his desires and indulge in her, she cheers on so that he does not lose to her temptations.

April Fool ぼさつサーヴァント


Bodhisattva Servant

The lewdest nun in the whole world.
The only thing on her mind is the pursuit for sexual desire.
To satisfy her own pleasure is her principle,
and so everyone else in the world are just a "side dish" for her.
