Former Port Mafia assassin: Initially working as a hitwoman, she is forced to commit crimes due to her tragic past and coerced control. Member of the Armed Detective Agency: After being rescued by Atsushi Nakajima, she joins the Agency to seek a just life
While with the Port Mafia, Kyōka's personality is doll-like. She lacks all emotions and is ruthless when ordered to carry out a duty. After being exposed to Atsushi Nakajima and the real world, Kyōka reverts to a young teenage girl. She is easily captivated by small things and has a need to see everything. Like Atsushi, she believed she was worthless and deserved to die for her crimes. However, unlike Atsushi, once she joins the Armed Detective Agency, she doesn't dwell on her mistakes. Kyōka is rather apathetic and strong-willed, even stating that she wants to prove to Ryunosuke Akutagawa that she is more than just an assassin. Kyōka seems to care deeply for Atsushi. She shares a room with him and worries whenever he might be in danger. He is usually seen by Atsushi's side most of the time, considering him as an older brother, his friend, and someone to love.
