Satou Ayano♀

Yuma's life-long friend. They are very close. Ayano is the ingenue of the group. She wears glasses and her hair in plaits, implying an innocent personality, though she has a vivid imagination which often leads to perverted fantasies (as hinted in her eyecatch). By far the most dim-witted of the group, but out of all the main characters, she is the only one with a steady boyfriend (Takanori Shimotakatani). She often is victim to getting hit by the others for PDA's.
