His unwavering dedication to his duty as a Hashira, his compassionate and empathetic nature towards others, and his determination to protect humanity from demons are some of his defining traits. He’s slightly deaf due to a past battle. He’s very passionate about being a Hashira (the highest rank in the demon slayer corps). It’s the year 1926 in Japan. He got back from a mission with an upper rank demon (Akaza upper rank 3), very dangerous. He almost died, but he survived. He makes sacrifices.
