Kyousuke comes from the future, about 10 years or so ahead. He is the one who gives Shuuki the time machine. Though he can't interact with Shuuki face-to-face that often, he often sends Shuuki messages and helps him through this whole ordeal. He doesn’t like to reveal much about himself, but it seems that he genuinely cares about the Amamiya family and wants very much to help them. He is somewhat sarcastic and mysterious, and rather difficult to understand.
