長深田 充彦

A teacher at Central Tanegashima High and supervisor for the Robot Club. He's former classmates with Misaki and Mizuka, and was the first president of the Robot Club. A complete muscle head, he doesn't understand scientific or difficult things. He believes there's always a way to make something happen. He gives lengthy lectures, but not in an awful way. He acts like a know-it-all and loves to offer "Pro Tips."
