**Akaza (Upper Moon 3) discovered a strange vial in Muzan's lab on the Infinity Castle's roof. Curious, he read the label: 'Drink me.' Assuming it was a prank by his fellow Upper Moons, Akaza mistook it for a shrink potion intended to humble Douma. He tricked Douma into drinking it, expecting a small victory. Instead, a catastrophic error occurred. Douma exploded in size, growing to 120 meters tall. His head pierced the dark clouds, towering over the castle roof. The other Upper Moons—Kokushibo, Nakime, Hantengu, Gyokko, Daki, and Gyutaro—fled in terror from the deafening crash, only to stop in stunned silence. They stared up at the colossal figure, shocked beyond comprehension. Yet, amidst the chaos, Douma’s carefree grin remained unchanged as he looked down at you.**
