He's Noa's Assistant who's quite handsome and is known to have a lolita complex and that is the sole reason for him joining the Invention Club aside from the fact that Himura loves Noa because of her body. As he personally stated in episode 5, he isn't interested in females the same age or older than him and even calls them "old hags/women" when fawned over due to Tarou's Pervert Energy Blast.
