Description
Sion Ogura is a 15-year-old female student at Sakuragaoka High School, standing 154 cm tall with black hair, blue eyes, and circular glasses, typically seen in her school uniform with a black hairband. Born on December 14 with blood type A (occasionally mistaken for type B), her name derives from the demon Gusion, associated with knowledge, time, and tomes. Gusion describes her as "a fragment of myself I left behind, the last page of my life's story." She possesses rapid reading skills and above-average deductive reasoning but no notable supernatural abilities.
A genius with exceptional academic performance, Sion lacks ethical awareness, particularly in occult research. She founded the school's unauthorized Black Magic Research Club, utilizing classrooms and equipment without permission; her high grades lead teachers to overlook these activities. Her personality blends eccentricity, chaotic experimentation, and social awkwardness. Anri Sata notes interactions may require "self-defense." Sion exhibits low physical stamina, often less than Yuko Yoshida's, and avoids outdoor activities, especially mountains or crowded places. She typically panics and flees during confrontations, citing her aversion to the outdoors.
Her primary focus is researching black magic and the occult, frequently developing experimental potions and gadgets like an herbal potion boosting magical power or a "corruption stabilizer" crafted from rare pink jade. She proposes ethically questionable experiments, such as extracting Yuko Yoshida's blood or administering electric currents, usually thwarted by Momo Chiyoda. She also creates unconventional items like emergency help buttons glued to apartments and handmade dolls.
After the Black Magic Research Club's room is destroyed by Mikan Hinatsuki's curse, Sion secretly relocates to the attic above the Yoshida residence. From there, she surveils Lilith's sealed idol and patrols Yuko's neighborhood five times weekly. She assists in locating Sakura Chiyoda's hidden spring and intervenes at critical moments with tailored solutions, like creating an elixir from therapeutic spring water to stabilize Momo Chiyoda's fluctuating energies. Her actions consistently contribute to resolving crises, positioning her as an unseen pivotal figure.
Sion maintains complex relationships: viewing Yuko Yoshida as a primary test subject due to fascination with her demon heritage, tolerated by Anri Sata despite unsettling behavior, and collaborating with Momo Chiyoda for mutual benefit or research. Ryoko Yoshida displays trust in her. Her involvement spans multiple arcs, including coordinating a rescue operation termed the "summer excitement experiment" where she dressed as a medieval doctor distributing untested "weird medicine." She gathers resources without consent, attempting to collect Shirosawa's hair and inscribing magical seals on walls.
Her character development shows increased narrative integration, involving covert observation with experimental equipment and strategic interventions. Despite her chaotic methodology, her inventions and insights repeatedly prove instrumental in overcoming obstacles, solidifying her role as an unconventional but essential ally.
