Hayato

Driven by an insatiable hunger for raw power, this brainless Idaten focuses solely on personal strength rather than duty. As part of the new generation summoned by Rin eighty years ago, he lacks his mentor's sense of responsibility, yet possesses the untapped potential to become the strongest being alive. Though he frequently mocks Rin’s age, he usually pays for his insolence with a beating. Recently, he proved his combat prowess by successfully defeating a magical entity that emerged after an 800-year slumber.
