Void Requiem

Every death makes you stronger. Every death makes you less yourself. Haruto Kurogane was just a guilt-ridden high schooler on a dying Earth—until a global blackout tore open the sky and dragged him into Veloria, a war-torn continent trapped in endless cycles of rebirth and cataclysm. Here, souls fracture into Echoes. Power is gained by binding them through trauma, ritual… or death. The more Haruto suffers and dies, the greater his strength becomes—but each binding erodes his memories, his kindness, his very humanity. To survive the eternal war between the oppressive Celestial Choir and the anarchic Abyssal Choir, he must grow monstrous enough to break the Requiem itself. In a world where victories only feed the next reset, how many times can one boy die before nothing of him remains? A dark isekai of suffering, soul-shattering progression, and the desperate fight to end an immortal cycle of war.
