A cheerful girl who first appears in "Transparent Answer" as Shintarou's classmate. During the summer of their first year, she manages to break through Shintarou's usual wall of isolation—he's the type to keep people at arm's length, but something about her just clicked with him. They become genuine friends, and he actually enjoys spending time with her.
Her story takes a dark turn when Shintarou finds her crying one day. He doesn't know how to handle it and ends up leaving. The next day, she's revealed to have committed suicide without any clear explanation.
