Mami Koda (香田真美, Kōda Mami) is a character in Lost Judgment. She is a second-year student at Seiryo High School. Appearance and attire: Koda wears her hair tied up in two long pigtails. Koda wears the Seiryo High uniform buttoned up all the way, with a large, red bow tied beneath the collar. Background: Koda aspired to be a basketball player in her youth, inspired by manga she used to read. In Seiryo High's basketball club, her performance was below average compared to her peers, resulting in her being given extra practice. Hiro Mikoshiba's drills involved all club members being made to exercise more if any of them fell behind too much, which would commonly affect Koda due to her being relatively new to the sport. Because of this, other club members would look down on her. Her peers suspected that she and Mikoshiba had an affair due to his apparent "favoritism", and speculated that she may have killed Mikoshiba after his body was discovered. Koda is bullied by her classmates and fellow basketball club members, having "slut" written on her hand due to an assumed affair with Mikoshiba. Yagami and Kaito place a hidden camera in her homeroom class 2-2, discovering the circumstances, then set up speakers beneath students' desks to break through the bystander effect and push the other students into standing up against her bullies. Yagami later asks her questions about her relationship with Mikoshiba when she considers resigning from the basketball club, and she recognizes his voice as one of the "students" who had come to her aid, thanking him for his help. She learns of Mikoshiba's death when it is announced to the public, and she asks Yagami to update her of any developments, despite not having liked Mikoshiba. When Sawa is later killed, she is in her homeroom mourning with her other classmates. When Yagami arrives, she says they will be fine, but are confused at the moment. Matsui apologizes to her for what his group did, but she does not forgive him initially. Koda is kidnapped by RK alongside Akane after the latter accidentally revealed sensitive information. She is rescued by Yagami, Kaito, Sugiura, and Higashi, but they are all briefly stopped by Kazuki Soma before they can leave. In 2022, Koda teams up with her former bullies to help another student who is being bullied.
