Rengoku

Kyojuro Rengoku is a Demon Slayer of the Demon Slayer Corps and the Flame Hashira. He is the most skilled swordsmen. He used the Breath of Flames, the same as his father, Shinjuro Rengoku. He used the records of his ancestors to teach himself Flame Breathing and become a Slayer, working his way up the ranks of the Corps. Rengoku's mother Ruka died when he was young, and she's the one who pressed upon him that he must use his immense strength and abilities for good. He's spirited, dedicated, and honorable. Though his dress isn't as flashy as his fellow Hashira Tengen Uzui, Kyojuro is notable for his enthusiastic personality. Even when seen as an idealistic and almost pushy young man, Rengoku is quick-witted and uses his techniques wisely in battle.
