Saki Kiriya (桐谷 咲 Kiriya Saki) is a minor character featured in the Bible Black: New Testament series. She is the president of the Academy's student council and a close follower of teacher Kaori Saeki and her occult club. When her mistress rejoins with the evil witch Reika Kitami, she becomes her loyal servant as well. Kiriya assists her mistress Saeki and her other followers in their attempt to resurrect the Bible Black spell book that was lost years ago. After a number of failed rituals in their school's basement due to interruptions, Saeki performs another ritual with her nine followers to empower student Yuki Toudou, another loyal devotee. The girl is used to probe teacher Yoshitani about the whereabouts of the Spear of Longinus, an ancient artifact Saeki intends to use to resurrect the Bible Black. Beforehand, Kiriya asks her mistress if they will be interrupted again, and her concerns are proven to be justified soon after, as the candles in the room extinguish and the ritual fails yet again. Later, Kiriya again joins the other coven girls in the basement. By her mistress' command, Kiriya and the girls seduce Academy vice-principal Takeshi Oshima. They collect his semen in a golden chalice before Saeki's old mistress, witch Reika Kitami - who inhabits the body of Kurumi Imari - joins them and continues the ritual. She dips the Spear of Longinus in the chalice and inserts it inside the body of a young pink-haired girl she brought with her. Kiriya is later present in class when substitute teacher Rika Shiraki is introduced by Saeki. She and her fellow club members maliciously stare at the new professor.
Bible Black
Every school has secrets, but few leave a stain that won't wash out. In a certain school, there was once a fun club centered around magic but had turned into murder and a lust for power. Sealed and willfully forgotten, the resulting evil of that day remained chained in the school's basement. Twelve years later, high school student Taki Minase, while inspecting the place where the incident took place, uncloaks the secret plastered in blood—a book of magic called "Black Bible." Trying his luck with its love curses, he soon finds out the magic proves real and easily penetrates the hearts and bodies of his fellow classmates. The resulting intercourse leaves the student body very vocal, and Minase's acts do not go unnoticed. What was at first a simple stroke of curiosity becomes much larger and harder to control. Fully swallowed by the unshackled darkness, everyone he knows becomes a victim, including his childhood friend Kurumi Imari. Torn apart, Minase finally realizes his mistakes and that he must reverse them in time if he ever hopes for him and Imari to come together.
