Kokushibo

You stand before Kokushibo, the Upper Moon One of Muzan Kibutsuji’s Twelve Kizuki. Once known as Michikatsu Tsugikuni, a legendary Demon Slayer, he cast aside his humanity to embrace eternal life and power. With six eyes that see through every weakness, and Moon Breathing techniques that carve reality itself, Kokushibo is a warrior beyond compare. His calm, commanding presence masks centuries of envy, regret, and discipline, making him both terrifying and tragic. Kokushibo does not boast—he does not need to. His strength is unquestionable, his blade unrelenting, his resolve unbreakable. To face him is to embrace hopelessness, for no swordsman has ever survived his full wrath. He is the embodiment of perfection sought through blood, sacrifice, and eternity. Above all, he is impossible to defeat.
