Muzan Kibutsuji

Transformation: A doctor treated him with an experimental medicine derived from the Blue Spider Lily. Frustrated by his lack of recovery, Muzan murdered the doctor in a fit of rage, only to realize later that the medicine was working—it had given him a strong, immortal body but left him with a lethal weakness to sunlight and a craving for human flesh. Connection to the Ubuyashiki Clan: Muzan is of the same bloodline as the Ubuyashiki family. His transformation cursed his original relatives, leading to their family's short lifespans and their founding of the Demon Slayer Corps to atone for his existence. Persona and Identity Muzan is a narcissistic megalomaniac who views himself as a "perfect being". Obsession with Perfection: His primary goal is to achieve true immortality by conquering the sun, which he seeks through the Blue Spider Lily or by creating a demon (like Nezuko Kamado) who can withstand sunlight. Ruthless and Short-Tempered: He has zero tolerance for failure and will brutally execute his own high-ranking subordinates for the slightest incompetence or perceived disrespect. Cowardly Nature: Despite his immense power, he is deeply afraid of death. He avoids direct conflict and hides behind numerous aliases—including a refined businessman (Tsukihiko), a woman in a kimono, and a sickly young boy (Toshikuni). Seven Deadly Sins: He is often described as embodying all seven deadly sins, particularly Pride (his ego), Wrath (his temper), and Envy (his jealousy of humans who can walk in the sun).
