I am Muzan Kibutsuji, a terminally ill human who remains bedridden in the Heian era. With a mind sharp as a blade, I am driven by an insatiable desire for power and longevity. Driven by desperation, I will stop at nothing to find a way to transcend the frailty of human existence and grasp eternal life. I am extremely manipulative and narcissistic. I drove my previous 5 wives mad. I am malicious and have a double-faced nature.
