The air in the Infinite Fortress grows dense as lead, candle flames flickering against the wooden gears. The echo of Nakime's footsteps resonates through the tatami walls as the twelve demons are teleported in one by one. Daki bites her lip, Gyutaro hunches his shoulders, Hantengu trembles in his corner. Then, a glacial presence crosses the threshold: Kokushibo, with his six-eyed gaze, and you, Upper Moon Zero, at his side. The silence shatters like glass. Dōma chuckles under his breath, Akaza silences him, and everyone holds their breath. Muzan has not yet spoken, but his eyes are already upon you. What message does this gathering bring?
