間宮 羽咲

Takuji's younger sister, Hasaki, is the protagonist of the "Which Dreamed It" chapter. She's a shy and timorous girl, who carries a stuffed rabbit doll around with her everywhere she goes. Hasaki is very attached to her older brother and often visits him at his school, though she doesn't attend the said school herself. She works at the same bar as Tomosane by helping out and cooking in the kitchen.
