Ai Hayama
A free-spirited part-time cram school lecturer with dreams of becoming a photographer. Her favorite subject of photography is capturing people's expressions on camera. She's very popular among her students, with the ones friendly with her calling her "Ai-chan." Her personality is similar to an older sister you can rely on and tell you troubles to. When she wants to do something, she will do it no matter what, resulting in her retirement at Kadonari Seminar Cram School.
