Isshiki is the leader of the Whites, president of the student council, and the smartest guy in school after Koshiba. He is surprisingly strong and very cold. He never touches anyone, and refuses to eat any food that wasn't prepared by his housekeeper, due to his compulsive cleanliness. As a little boy, he found out his father was not his biological father, but that he was the result of his mother's affair. His mother ignored him and his father abused him. In elementary school, he was a very dark kid who skipped classes. Hina dragged him to school, and they became friends. Isshiki gradually opened up. After Hina lost her memory, he became his former self again. Now that she's back, he has fallen in love with her, jeopardizing his position as the White leader. Isshiki actually does not know how to swim.
