Description
Hiroko Takashiro first explored occult practices as an academy student, drawn to witchcraft through a belief in the power of darkness to perform miracles and reveal historical truths. She formed an unofficial witchcraft club with classmates Rie Morita and Shidou Saki, initially engaging in tarot games and ritual imitations. Their discovery of the mysterious grimoire Bible Black at a bookstore, acquired cheaply, marked a turning point. Early experiments included casting a lust spell on student council member Junko Mochida, forcing her into public masturbation during an assembly, an act that solidified the club's belief in the book and amplified their influence.
Further notoriety came when they used a love charm to make student council president Nami Kozono fall for unpopular student Hiratani, leading the group to sell charms for profit. Kozono later begged Takashiro to strengthen Hiratani's affection, but Takashiro instead dispelled the charm to demonstrate control. Kozono then joined the group, now called Rose Cross, securing the school basement as their ritual space and arranging for a human sacrifice. A practice ritual to summon a lesser demon using a puppy sacrifice backfired, resulting in Takashiro being raped by the demon and left comatose for three days. This trauma revealed their dangerous amateurism; she urged abandonment of their plans but was ignored. Kozono usurped leadership and ordered Rie and Saki to lock Takashiro away on Walpurgis Night. Escaping, she found her friends slaughtered and the Bible Black gone.
Twelve years later, Takashiro returned to the academy as an art teacher and club advisor. Having studied white magic, she guarded the basement, believing herself the sole keeper of its dark history. Lingering psychological trauma from her demonic encounter manifested in flashbacks and episodes of arousal. After seeing a demonic image in the library, she masturbated in a restroom but was caught and assaulted by the seemingly possessed vice-principal; unresolved cravings led to consensual sex. Her attractive appearance made her popular with students, some drawing explicit images of her, and she experienced sexual fantasies about them.
Growing suspicious of school nurse Reika Kitami amid strange events, Takashiro warned art student Taki Minase about her, suspecting primitive magic. Minase ignored her warnings, became corrupted by Kitami, and assisted in her kidnapping. Kaori Saeki stunned her, and she was taken to Saeki's apartment, enduring water torture and repeated rape. Kitami forced her to confess her role in Rose Cross and revealed Takashiro was the intended human sacrifice twelve years prior. Under sexual stimulants administered by Kitami, Takashiro was subjected to non-consensual acts with several art students. Minase eventually rescued her, taking her to his home where she discovered the Bible Black and learned of Kitami's devil contract.
Takashiro and Minase researched the Forbidden Spell to stop Kitami's soul-exchange ritual with Kurumi Imari. The lingering stimulant effects led Takashiro to request sex with Minase twice to manage her arousal. After Minase was stabbed by Rika Shiraki, Takashiro magically stunned Shiraki and healed Minase. They proceeded to the school on Walpurgis Night; Takashiro broke Kitami's barrier and incapacitated Saeki and allies. During the ritual interruption, Takashiro was restrained and raped by Kitami's followers while Minase recited the spell, killing Kitami's physical form. Takashiro later erased the memories of those involved and discovered Kitami's soul survived within Imari. She sealed Kitami's soul inside Imari, making her forget.
Subsequently, Takashiro left teaching to study various religions, seeking to rid herself of bodily temptations. She adopted a secluded life as a nun, wearing a simple purple robe and veil. During this period, she was sexually assaulted by two thugs downtown and later had an encounter with a monk or priest at a monastery. Continuing her quest for purification, she eventually climbed a mountain. Her path led to marriage with Hitoshi Hidaka and the birth of their child, Aoi. She maintained a friendship with Tsunade and reunited with former student Kurumi Imari, now a psychic investigator. Takashiro expressed hope for Reika Kitami's soul to find peace after Kitami's spirit apologized to Imari.
