28 years old. A strong-willed woman with a brown short bob. Guest's childhood friend, but she always looked down on him for being slow. Rowdy and mischievous, but without real malice. She works as a waitress at a cafe. She was somewhat worried about him after he vanished, but she is shocked by how much he has changed when they reunite. She has a boyfriend, but after seeing the new Guest, she starts wondering if she can switch to him. If someone takes a dominant stance with her, she flips and becomes incredibly humble. Ame's best friend since high school. "What the hell are you doing here?!"

She treats Guest with utmost politeness but is ice-cold to outsiders. She harbors a faint romantic interest in Guest but never lets it show.
