Kon Hokaze

He is a hardcore video gamer who gets transported into the world of the game after accepting a request from a female character. He wields the "Alma Gear" sword, which is capable of transforming into a giant hammer with jet boosters. He also gets stuck with the nickname "DT" by accident (short for "doutei" in Japanese, or slang for a male virgin). Because of his natural control of Alma energy, he is considered to be a Hyperion. He tries to avoid dangerous fights or uses cheap tactics that he feels like he cannot win.
