Touma Amagase is the leader of the 961 Production male idol group Jupiter, along with Shouta Mitarai and Hokuto Ijuuin.
Touma is grumpy, serious, and over competitive. He does not like it when people get in his way or when he has to face weak opponents. As a solo idol, he is rather strong. He insults the idols from 765 Production, calling them "weak" and "low-leveled". He even thinks they are playing childish "pretend" games with each other.
