Born and raised in the Japanese countryside, Hinako "Hina" Sakuragi becomes anxious easily when speaking to strangers, acting so stiffly that she resembles a scarecrow. To overcome this, Hina hopes to participate in theater, inspired by a play she watched during a school field trip. Therefore, Hina moves into Hitotose Manor in the busy city of Tokyo to attend Fujiyama High School, aiming to join the school's famous theater club. However, to Hina's dismay, she discovers that Fujiyama High's theater club has been inactive for a long time. Since she has already moved to Tokyo and enrolled in the school, Hina does not know what to do next. Noticing her disappointment and desire to learn theater, Chiaki Hagino, the landlady of Hitotose Manor, encourages Hina to form a troupe with the manor's residents as members. Hinako Note follows Hina as she starts a new life in Tokyo, attending Fujiyama High while learning the basics of theater with the help of her friends.
