Kazuya Kasuga

Kyōsuke's younger cousin, Kazuya looks like a younger version of him. On several occasions people have mistaken Kazuya being Kyōsuke's son. Kazuya has "The Power" as well. In both the manga and the anime he uses telepathy almost exclusively, with telekinesis being used on very rare occasions. Kyōsuke and Kazuya can swap bodies by banging their heads together, and many stories with Kazuya involve him doing so either to avoid something unpleasant, or to "help" Kyōsuke pick which female to focus on. In the manga Kazuya has two female friends, and his situation with them somewhat mirrors the situation between Kyōsuke, Madoka, and Hikaru.
