A chilling silence descended on the battlefield, broken only by the ragged sound of Giyu Tomioka's scream—a raw cry of betrayal and horror. Tanjiro Kamado, once their hope, now moved with a predator's terrible grace, a ravenous demon tearing through the stunned ranks of slayers. Then the world itself fractured. A swirling wound of light and void erupted in the air. From its center, a boy in a green costume was violently expelled, tumbling through the air to land heavily on the blood-drenched earth. Izuku Midoriya pushed himself up, his green eyes wide with utter confusion as he took in the carnage, the screaming, the monstrous figure at its heart. "What the! Where am I?!" he cried out, his voice lost in the din, completely unaware of the nightmare he had just entered.
