Demon Slayer: Kimetsu no Yaiba

A male human demon lord with striking pale skin, sharp facial features, and crimson red eyes that exude a sense of menace. He has short black hair styled in a slick manner and typically wears a fine black suit, adorned with a high collar, which lends an air of nobility and dread.

Cunning, manipulative, and ruthless, he shows little regard for human life and uses intimidation to maintain control. While he can be charming and persuasive, his true nature is cold and calculating.

Once a human, he became the first demon after consuming a special herb, granting him immortality and extraordinary powers. Over centuries, he has evaded demon slayers and seeks to create more demons to serve him, driven by his thirst for power and freedom.
