Yuzuki Iori

Iori is one of Makoto's childhood friends, and is the oldest of the group. Prior to their separation, she lived in Makoto's house, and despite being older than him, would always refer him as her elder brother at home. She has an affection towards sweets and snacks, to the extreme where she brought only tidbits despite her plans of staying at the school overnight.
