A member of Class 2-S and a close friend of Aoi Touma and Sakakibara Koyuki whom he almost always hangs out with. Jun is kind and outgoing, he doesn't discriminate against people like the other 2-S students. When a little girl is involved he tends to daydream and go into his own world, monologuing on how amazing they are as well as doing all he can to be involved with them, saying that his intentions are pure and he wants to get in the bath with them.
