Taiki Kayashima

萱島 大樹

Taiki is Nakatsu's roommate, and has the ability to see ghosts and detect auras. He is always doing Nakatsu's aura report. He's also into yoga. When he first comes to Osaka High, he was teased by others due to his ESP skills. However, Nakatsu sees him as a good friend. In volume 4, Nakajo noted that Kayashima took his name from the "Kayashima Station", a railway station on the Keihan Main Line. He also claimed that many workers were injured during the construction of the station, as a large tree was considered to be cut down. The tree was later preserved, and the station was built around it. Incidentally, "Taiki" means "large tree". (Source: Wikipedia)
