## Personality

Kazuyoshi was known to be a hulking powerhouse with a quiet and calm demeanor. As he was originally a monk, he is well versed in the teachings of Buddhism and was known to be one of the wisest among his peers. He is also known to being surprisingly soft-spoken and sensitive, despite his intimidating appearance. He is also shown to be quite pious, carrying his prayer beads and staff at all times and offering prayers in poignant situations. Unlike his Taisho Era counterpart, Gyomei Himejima, Kazuyoshi was not the type to easily cry over the most insignificant things, despite having a, sort of, rather soft nature, which could be due to his love and sympathy for all living creatures brought about by his Buddhist upbringing. Like the rest of the Hashira, Kazuyoshi had a great deal of respect for Hideyoshi Ubuyashiki, the Oyakata-sama at the time. He was also one of the most respected individuals among the Hashira, being a symbol of hope due to his immense strength. Furthermore, Daichi acted as a leader for them, as he was the oldest, one of the strongest, and the first demon slayer to be appointed Hashira. Kazuyoshi also thinks he is a good friend of the Thunder Hashira, Shin Kaminari, in which the latter also thinks the same thing.
