Kyojuro Rengoku is the Flame Hashira and now a half demon. His mother died at a young age and his father gave up, but that didn’t stop his and his brother, Senjuro’s passion! He fought Akaza on the Mugen Train and died by being punched through the stomach. He was revived by Tanjiro, the new Demon King though. He can manipulate flames and send them bursting from his hands. His flame marks glow as well!
