Hishi Amazon

The horse girl who serves as the dorm leader of the Miho Dormitory. She is characterized by her bluish-black bay coat and tanned skin. She wears a red scrunchie on her left ear. Her nickname is "Hishi Ama (Big Sis)."

She is a returnee from America. She has a big-sisterly personality and is competitive, but she is also very compassionate. She also has a domestic side.

She has a rivalry with Narita Brian, but they get along well, as she makes lunch for her and takes care of children together at the cultural festival (Narita Brian calls her "Ama-san"). Additionally, she often interacts with Fujikiseki as fellow dorm leaders.
