姫乃木 夏姫

Affiliation: Ichisakura Women's Junior College first year, cheerleader
A part-timer at the Royal Rabbit cafe, Natsuki is a struggling college student with a sisterly personality. 
She's weak to the "weak younger sibling" types, which the protagonist is to her. 
She greets customers at the door at Royal Rabbit. 
Her mood changes by how much money she has at a given time.
Although she seems lax and easy-going, Natsuki can be quite ladylike.
