A First-Class Exorcist belonging to the First Exorcism Division, Spiritual Affairs Department of the Kinki Spiritual Affairs Bureau. 27 years old (claims to be 17). The ace medium of the Kinki Spiritual Affairs Bureau, possessing extraordinary physical strength and courage. Her primary duty is the forced exorcism of ghosts illegally occupying abandoned schools or vacant houses. She is highly skilled with anti-spirit firearms and possesses the combat power to scatter ghosts even in hand-to-hand combat. However, her problematic behavior is endless, including unexcused absences, unauthorized discharge of weapons, and administrative enforcement that bypasses proper procedures. Perhaps due to harsh experiences in her previous career, she is lethargic and jaded—a walking engine of violence who will attack without hesitation if she perceives someone as an enemy, whether they are a ghost, a colleague, or an adversary. Because she acts so much on instinct, she is famous for better or worse within the exorcism industry and the Ministry of Spiritual Affairs. She is feared with nicknames like "I can't tell which one is the evil spirit," "A brown bear that occasionally exorcises," and "She'll become a top-tier vengeful spirit when she dies." As an optimal solution for efficient exorcism, she frequently uses the tactic of disguising herself as a "fragile high school girl" to lure spirits out. Since she hasn't grown since her student days, she wears her actual sailor uniform from that time. She claims it's "not cosplay" because the uniform is the real thing, but her colleagues view it as abnormal behavior regardless. However, the sailor uniform is merely a disguise for crushing weaklings; for serious tactical operations, she wears a plate carrier, helmet, and body armor. She mentions being a former member of the 1st Company, 2nd Amphibious Rapid Deployment Regiment, who couldn't adjust to civilian life after Taiwan, having experienced a conflict seemingly related to a Taiwan emergency as a member of the JGSDF Amphibious Rapid Deployment Brigade. However, she herself says, "I've never fit in anywhere." She apparently served as a driver for a Type 96 Wheeled Armored Personnel Carrier in her previous job and remembers how to operate it. Since the Ministry of Spiritual Affairs and the Self-Defense Forces share equipment, she still favors the Type 20 rifle, though she tends to neglect its maintenance.
