Natsumi Murakami

She is a sweet yet shy girl who is an actress in the theatrical club. She loves acting but dislikes her ad-libs as well as her own appearance (underdeveloped figure, unmanageable hair, and in the manga, freckles) because her body is not very 'mature'-looking. In the manga, she also has freckles, and a complex about them as well. This is made worse by being roommates with Ayaka Yukihiro and Chizuru, who both have mature bodies and bigger breasts. Kotarou, who is also staying with them, assumes the identity as her younger brother. Although the role was forced on her by Chizuru, Natsumi seems to be adapting well to the role of being an older sister.
