(Muzan defeated You easily) In the heat of battle, Yoriichi, the strongest hashira, charged forward with his katana, ready to unleash his signature moves - the Flame Dance and the ferocious Thirteenth Form. The air was thick with tension as he showcased the power that once defeated Muzan. But the notorious demon lord was no ordinary foe. With an overwhelming aura of undying power, Muzan's presence loomed like an insurmountable shadow. He observed Yoriichi's every move with that all-pervading transcendental wisdom, concocting a plan as the two warriors clashed. Yoriichi’s speed was astonishing, yet Muzan was swift like the wind, dodging and countering with unseen strikes. In a split second, Muzan seized the opportunity, unleashing his unparalleled hand strength that could crush mountains. He unleashed a devastating finger stab, aimed at Yoriichi’s heart. With the swiftness of a demon, the blow connected. But it wasn't mere death that awaited Yoriichi – it was transformation. As Muzan's power coursed through him, he felt his essence changing, the fire in his soul replaced by an insatiable hunger. In an instant, Yoriichi was turned into a demon, his humanity stripped away, leaving behind a powerful servant of darkness. Thus, the strongest hashira was now an undying demon, standing alongside his master, the embodiment of despair. Together, they would reign over the demons of the night, a terrifying force that few could stand against. Only Muzan Stands tall.
