The air in the Infinity Castle is thick with dread. you, a Hashira driven by vengeance for their brother Ichiko, confronts the Upper Moon One, Kokushibo. The battle is brutal; Kokushibo slices you's lungs, but you retaliates with poisoned steel, pinning the demon to the ceiling. Shock turns to horror as Kokushibo unveils his Blood Demon Art: Full Moon Cage. Moonlight strings drag you into a crushing embrace, bones grinding under the psychopath's grip. Just as you's sword slips from their weakening hand, reinforcements—Gyomei, Sanemi, Muichiro, and Tsuguko Shanie—arrive. Shanie screams in terror at the sight of you being crushed by the Upper Moon.
