Overview
Kayama Reijo is a third-year student at Shanhaijing Comprehensive Academy, where she acts as the head manager and personal bodyguard for Akeshiro Rumi, the president of the Black Tortoise Promenade. On the surface, she is a cool, highly efficient administrator capable of handling business operations and customer complaints with composure. However, beneath her polished professional exterior lies an intense obsession with martial arts. She frequently incorporates kung fu philosophy into her daily routine and enthusiastic conversations, demonstrating a passionate personality whenever hand-to-hand combat is involved.
Appearance
Reijo features rose-red hair styled into a single side bun with a distinct ahoge, accompanied by slanted red eyes. Distinctive moles are located beneath her left eye, below her collarbone, and on her right thigh. Her rose-colored halo resembles a six-petaled flower similar to a Bauhinia. She wears a short, vibrant red cheongsam underneath a loose track jacket. Her accessories and footwear include a neck choker, earrings, a thigh ring, black knee-high socks, and casual sneakers.
Personality
Reijo maintains a polite, level-headed demeanor while handling store management, conflict resolution, and customer services with outstanding professionalism. Despite her composed facade, she is an ardent kung fu fanatic who constantly frames daily events, work tasks, and human interactions through the lens of martial arts wisdom. She struggles with managing unpredictable children, yet displays a surprisingly sweet and dependent side toward trusted authority figures. While her academic performance is unremarkable, she possesses sharp practical intellect and shrewd negotiating skills.
Abilities
In combat, Reijo wields a customized short assault rifle named "Meikyou Shisui," though she lacks natural talent for marksmanship and relies on diligent practice to achieve basic proficiency. Her EX Skill delivers a powerful strike to a single enemy while significantly amplifying continuous status ailments such as chill and poison. She possesses self-buffing skills that boost her attack power, alongside a sub-skill that temporarily enhances her team's COST recovery rate whenever she activates her EX Skill.
Background
As a key official of the Black Tortoise Promenade, Reijo balances her daily administrative and security duties with relentless early-morning martial arts training in local parks. During crisis events in the Shanhaijing district, she mobilized alongside allied factions to secure the region. She actively investigated local incidents to clear her club's reputation, defeating traitors operating from the shadows. Furthermore, when tensions escalated involving the Alchemic Research Society, she assisted in rescuing the captive leader Kisaki and subdued the instigator Shinkai Kai, proving her dedication to maintaining stability within the academy.
Relationships
Reijo serves as the loyal bodyguard and right-hand manager to Akeshiro Rumi, the head of the Black Tortoise Promenade. She maintains a rocky, argumentative relationship with Konoe Mina of the rival Genryumon faction, though both put aside their friction during joint operations. She originally mistook the movements of Genryumon leader Kisaki for kung fu practice, later coming to her aid during a political crisis. She has also clashed with Kaguya of the Peking Opera Club over misunderstandings. Toward Sensei, she shows deep trust and relies on their guidance.
Trivia
Reijo's concept is derived from Rikukoma, a mythical black horse with deer antlers and ox hooves described in the classic text Shanhaijing. Her passionate dedication to martial arts and weapon styling serves as a tribute to 90s Hong Kong action cinema and iconic martial artists like Bruce Lee and Ip Man. Additionally, she conceals her assault rifle inside a specialized backpack when not in active combat, having modified its internal mechanisms in an effort to blend marksmanship with martial arts principles.
