Hikari Amamiya

Hikaris parents divorced when she was in elementary school. Because of this she tends to not trust other people and doesnt say what she really thinks. She still keeps up with everyone in her class but actually finds it annoying to talk to them. Since Hikari is born in August that makes her the younger sister of Mizuki.https://anilist.co/character/210828/MizukiSuzumura
