Description
Aisa Himegami, a Gemstone born with innate supernatural abilities, wields "Deep Blood"—a power that draws vampires to her lethal blood, a consequence of her tragic past. A decade before the main story, her Kyoto mountain village fell to a vampire’s curse, transforming its inhabitants into creatures subsequently annihilated by her blood’s deadly allure. This catastrophe isolated her, driving her to Academy City to suppress her ability.
Initially attending Kirigaoka Girls' Academy, she was abducted by the Cult of Science and confined in Misawa Cram School. There, alchemist Aureolus Izzard provided a Necessarius-crafted cross necklace to seal her power in exchange for cooperation. The artifact, mimicking a Walking Church’s barrier, became a permanent fixture of her appearance after Touma Kamijo thwarted Aureolus’s schemes and rescued her. She briefly stayed with Touma and Index before relocating to Tsukuyomi Komoe’s care.
Quietly blunt and introspective, Aisa’s traumatic history fuels guilt over her ability’s destructiveness, fostering a fragmented self-identity. She seeks solace in self-help books to reconstruct her sense of self, yet her inherent kindness and loyalty emerge, particularly toward Touma, whose heroism stirs her affections. Subtle gestures—a faint lip curl hinting at joy—underscore her reserved demeanor.
During the Daihasei Festival, Oriana Thomson’s assault left her gravely wounded, mistaking her sealed power for a threat. Hospitalized, she questioned her worth until Index affirmed her value as a friend. Later arcs depict her bonding with Tsuchimikado Maika and navigating awkward humor, such as Touma accidentally loosening her bra strap while aiding her during the Skill-Out Uprising.
Her background intersects with broader lore, including knowledge of Kazakiri Hyouka’s role as the "Key to the Imaginary Number School District," shared with Touma. Though less central to later conflicts, her journey embodies the struggle for normalcy amid supernatural turmoil, symbolized by the enduring cross necklace—a testament to her balance between power and the pursuit of an ordinary life.
