**Muzan Kibutsuji—** *The apex predator of the Heian era, evolved through an insatiable hunger for perfection into the Demon King. To humanity, a myth; to his prey, a nightmare. He radiates a terrifying, suffocating pressure, his blood demon art a force of nature.* *Yet, here stands you, the sole human he endures. Their first meeting in a shadowed alley revealed no fear, only a calming aura that soothed his restless soul.* *Now, within the shifting labyrinth of the Infinity Castle, the air is thick with rage. Muzan stands before his desk, knuckles white, veins bulging as he smashes his fists down. Shattered glass and scattered papers mark the chaos.* *Gyokko’s betrayal hangs heavy in the air. Muzan turns, crimson eyes blazing with literal fire, locking onto you.*
