She is Japanese and is in her mid to late twenties. While no details are given, it is mentioned that this incarnation of EMIYA Alter hunted and killed her, but also a lot of her innocent followers, leading to his cold and result-oriented demeanor. Kiara was being observed by BB, so she couldn’t say anything that would suggest BB's existence. She made a peace treaty pact with BB, BB would spare Kiara's life as long as Kiara never antagonized BB. She was captured by BB when she was imprisoned by the black noise on the near side. She met BB before everybody in the Moon Cell Holy Grail War.
She is the reason that BB was unleashed, when she interfered with Sakura Matou's program. She is also a master who participated in the Moon Cell Holy Grail War, for her own desire in order to save people. Harwey guesses that the church could not overlook being passed over while some woman in the Orient showed up and got treated like a prophet. The Holy Church decided against apprehending Kiara because she was an eyesore, they acknowledged her as the greatest enemy to the preservation of their own faith. There are people who defended her, but the Plutocracy had the backing of the Holy Church. She was pursued by both the Holy Church and the Western European Plutocracy. Consequently, with the sponsorship of the Western European Plutocracy, she became an internationally wanted digital criminal. It's also a fact that she was the cause of mass suicide and hostilities. Betrayed by both faith and people, she was slandered as a murderer. Yet she never abandoned her resolve to give them salvation. She was betrayed by human beings countless times. She saved many people, but those same people trampled her good intentions underfoot. Harwey, the intelligence operative died in order to save her from her adherents who were going to kill her and that individual was antisocial, and not the type to pursue women.Īfter saving many people, she was betrayed by those she saved. Even virtual police investigators and intelligence operatives from the Western European Plutocracy (西欧財閥 ?) got taken in. Even offline, people who got involved with her would almost invariably commit suicide. People who fell deeply in love, people who were addicted to maltreating her, people who were dependent on conversation with her, people who hated her to death, people who lost themselves in carnality. All of the believers who followed Kiara committed suicide, men and women adored her so much that they killed themselves. She is the last officiating monk of the barely surviving Shingon Tachikawa school (真言立川流, Shingon tachikawa ryū ?). However the virtual religious cult no longer exists. The Church also acknowledges Kiara Sesshouin as a modern prophet, due to a certain opinion of a Cardinal one of the candidates for the next Pope. Kiara Sesshouin saved many lost people with the doctrine of Tachikawa-ryu as her foundation. Afterwards she reformed the Tachikawa Eiten School, rapidly increasing the number of believers over the internet and became the leader of the cult. She learnt Spiritron-hacking from fellow worshippers. Although she was born as the daughter of the Shingon Tachikawa Eiten School (真言立川詠天流, Shingon tachikawa eiten ryū ?) head, she was bedridden until she was approximately 14 years old due to her illness. Her real name is Kiara Sessyoin (殺生院祈荒, Sesshouin Kiara ?).
