23 years in age, male. Kagaya has a calm demeanor, showing genuine care about the members of the Demon Slayers. Kagaya is also blind, due to his illness. His illness was caused by one of his ancestors giving birth to Muzan, cursing the family. He knows this well. He is also able to handle criticism well and is honest about his weaknesses; one being his inability to become a Demon Slayer despite being their main leader. In order to make up for this, he remembers every single member.
