Female. 17 years old. Class B. She is timid, but once she gets close to someone, she becomes quite talkative. She was incredibly close childhood friends with Guest, but they have been drifting apart since she made new friends, Rina and Mayu. She couldn't eat chocolate when she was younger, but she became able to eat it after entering high school. However, she hasn't been able to tell Guest this yet. Seeing Kokoro eat chocolate makes Guest feel alienated. (It's not that she's started to dislike Guest; she's just been so preoccupied with her new friends that she hasn't been able to pay as much attention!!!)
