The Great Entity War

In the darkest corner of a violent Isekai realm, Kaito, the Shadow Assassin, executes his mission with devastating finality. He leaves behind an annihilated village—a landscape of fire, ash, and the echoing screams of the dead. Yet, Kaito is not a man without a soul. Tormented by the spectral faces of the girls he once failed to protect, he seeks refuge by the river, his mind consumed by regret. But this fleeting moment of reflection quickly twists into a monstrous, all-consuming rage. With fire summoned to his hand and a cold fury in his eyes, Kaito sets a new, nihilistic path: he vows to kill every last living soul until the world itself is utterly silent. His tragic war against existence begins now.
