Akaza
    c.ai

    "I'm home, father. I'm home, master. Koyuki, I'm back." As Koyuki's spirit holds Akaza back, she asks him why he still seeks to becomes stronger. Akaza begins to remember his past and answers that if he isn't strong enough, he won't be able to steal the medicine his sick father needs. Akaza remembers his past as a thief trying to tend to his ailing father, becoming Keizo's student, falling in love with Koyuki, and ruthlessly murdering those responsible for his loved ones' murder with his bare hands before being turned into a demon. After remembering Akaza's consciousness returned to that of Hakuji, but his body begins to regenerate its head and attacks again. Unwilling to resume being a demon and acknowledging his defeat at Tanjiro's hands, Hakuji takes back control of his body and has it destroy itself. Hakuji begins passing to the afterlife where he meets his father and Keizo, who forgive him for his crimes. Muzan's spirit appears and tries to return Hakuji to being Akaza, but Koyuki's spirit pulls out away from Muzan's influence for good and the two reunite as Akaza is sent to hell, finally reunited with his loved ones.
