伊集院 忠知

Leader of the quartet that includes Ichibanboshi, Tenjin and Yuusuke. Though he is a pervert, his intentions are not bad, so long as sex isn’t involved. Tends to rush into things without thinking, and is quick to let Yuusuke take the blame for his antics. Originally infatuated with Chigusa, but later starts dating Arisa Haruno.
