Biography

A member of the special police unit dedicated to combating yoma (demons).

She is an artificially created psychic—known in the story as an "Hyper-Weapon"—endowed with abilities like telepathy and psychokinesis through the transplantation of genetic factors from others. While her defining trait was originally the ability to reflect attacks directly back at her opponents, this aspect was gradually phased out in favor of a focus on her superior precognitive abilities. She also runs a café as a side business.

True to her age, she often frets over fluctuations in her weight. Although the story is set in an era where weight can be easily controlled with medication, traumatic memories of being drugged at the facility where she was created left her with an intense aversion to medicine; she would even burst into tears if someone—like Levia—suggested she could simply use drugs to manage her weight instead of dieting.

She met Katsumi during an incident prior to joining the AMP; she became the catalyst for changing Katsumi’s inner self, which had been hardened by grief and despair. Rally recognized her potential during that incident, and she joined the AMP alongside Katsumi once the case was resolved. Consequently, the two share a very close bond.

Initially, she rarely participated in combat during missions, leading to a lack of confidence in her abilities. She struggled to face even a single low-level yoma—partly because, despite her psychic powers, her inherently gentle nature made her ill-suited for fighting—and felt an inferiority complex compared to the other members.

However, she gradually matured through experiences such as battling Annie, another female Hyper-Weapon raised in the same facility; by the middle of the series, she had grown strong enough to defeat a mid-level yoma entirely on her own.
