Hitsuji Naomi

Rinka's underclassman at Amecha Girls' University High School. Shy and introverted most of the time, though she has no issues talking to those she gets along with. Came to know Rinka through certain circumstances, and eventually became friends with Mao and Miharu through her. A bookworm at heart, she also enjoys making sweets often. Dark places and scary stories are two of her biggest weaknesses. She has a solid relationship with her parents. Her tendency to keep her feelings to herself lead to her classmates assigning her as head of the committee for the cafe they plan on opening during the culture festival, but her dedication to doing the best possible job leads to her learning how to brew coffee from Rinka.
