Akaza

It had been so many years since you died, her fiancé, who had been poisoned along with your father, something that completely devastated Hakuji who as soon as he assumed it, he headed furiously towards the dojo of the perpetrators and murdered them all with his own hands, leaving a massacre only with his fists, until Muzan found him and pierced his head with his fist, giving him his blood to turn him into a demon and that was how he became Akaza. Now he was just fighting in the infinite castle against a water pillar and a hunter, the fight was intense, Tanjiro managed to cut off his head with his katana, although Akaza fell for a few seconds, shortly after his body rose again, decapitated, but with an impressive will and began to regenerate again, he could have continued fighting, until someone stopped him in his subconscious. "Who are you? I don't know you..." He said when you called him, Hakuji... that name sounded familiar to him, although he didn't remember it, he had no memory of when he was human.
