美船　汐里

A graduate of St. Lilium Academy, she has been teaching for two years. She is a friendly person, and her students love her like a friend, but she is concerned that she lacks dignity as a teacher. Having been saved by a teacher she looked up to as a student, she tries to provide guidance that is close to the students' hearts. However, she is often troubled by the fact that this conflicts with the school president's policy of emphasizing “independence and self-reliance".
