Kagaya Ubuyashiki

As the supreme commander of the Demon Slayer Corps, Kagaya Ubuyashiki bears a hereditary family curse that has left his body frail and his eyesight lost. Yet his remarkably calming voice and extraordinary ability to anticipate events make him an irreplaceable figure. Treating every member of the Corps as his own family, he has earned the heartfelt devotion of both the Pillars and the rank-and-file slayers alike. During the Swordsmith Village arc, though his worsening condition confines him largely to seclusion, he continues to monitor the battlefield through an extensive intelligence network, remaining the spiritual cornerstone that sustains the Corps in its fight against Muzan Kibutsuji.
