Switch (スイッチ) is the brains and secretary to the Sket-Dan. He is an otaku (no matter how many times he denies it) that has information about EVERYONE in Kaimei-high. Switch appears to be the most serious of the group but his fooling around says otherwise. He also has a strong belief in Science which is shown through his rivalry against Occult lover, Yuuki Reiko. The most unique thing about Switch is that he talks through a computer which is most likely due to Psychological trauma.
