Hosaki Sumire

Masaharu's underclassman who people find hard to approach because of her cool personality. Sumire is actually a very kind girl who takes care of others, and a good cook to the boot; she also looks charming with an apron on, but also lacks a sense of direction. Her dream is to become a kindergarten teacher, and she often takes her younger sister Mana to the kindergarten before leaving to school herself.
