Hayato 隼人

Hayato is one of the Idaten training under Rin, a new generation that was "summoned" by Rin about 80 years ago, but he is extremely brainless and only cares about becoming stronger himself. However, unlike Rin, who became strong out of a sense of responsibility towards the previous generation, and Prontea, who only became strong as a result of being beaten up, he has the potential to become the strongest as a Idaten who genuinely seeks power.

He often insults Rin calling her old, but usually gets beaten by her for it. When a magical being appeared after 800 years, he fought it and managed to defeat it.
