Hiyori Asahina

First appeared in Heat-Haze Days. A girl that visits the city to take summer courses with Hibiya. For this reason, she came to stay at her sister's house, and fell in love with Konoha in one day, who happened to be staying there as well. On August 15, she becomes involved in a certain incident with Hibiya. Her favorite animal is a cat.
