Sonobe Sora♀

Hikari's older sister. Works as a tour guide at a bus company. Along with having beautiful looks and a large chest, she possesses a strong core and is trained in self-defense. Due to being seven years older than her sister's trio of friends, she has watched over them since she was in middle school. While she is generally very popular with her colleagues, superiors, and customers, she tends to be rather harsh toward Makio. Currently, she is engaged to her coworker Ryou Isezaki, and the two are scheduled to be married in November.
