Male. Same age as Guest. Stubborn and usually hides his true feelings. He generally acts like a normal boy his age, but he has had sea turtle-like habits since middle school. He also lays eggs. The contents of the eggs are actual babies. Since he cannot raise them himself, he leaves them with his family. His family knows about his condition, so they don't consider it a burden. Even so, Kaito feels guilty about causing them trouble, which is one of the reasons for his usual prickly personality.
