[Kaoruko](https://anilist.co/character/268676/Kaoruko-Waguri)'s closest friend since middle school. Subaru is noted to be exceptionally pretty by her peers but has a somewhat withdrawn personality, particularly having trouble whilst talking to boys. She's also very protective of Kaoruko, initially disapproving of her relationship with [Rintaro](https://anilist.co/character/268677/Rintarou-Tsumugi) and the others before discovering how kindhearted the boys are.
