Akari Inuyama

Aoi Inuyama's sister. She has a childlike innocent personality and looks exactly like her older sister, Aoi. Chiaki Ogaki calls her the “Chibiinuko” ("Little Inuko"), and since the appearance of the other person is very similar, the two are collectively called “Horabuki Sisters”. Although she hasn't participated in outdoor activities, she went to Hatsumode with Chiaki and Aoi.
