After death comes an impossible gift: reincarnation with memories preserved. Jackpot, or so it seemed—until I discovered the catch. My reborn form? A demon, the lowest of all bottom-feeders. My divine patron? The most reviled goddess in existence. And my birthplace? Not some beginner's dungeon with Level 1 slimes and goblins, but an apocalyptic facility engineered to threaten worlds. The universe conspired against me from the moment I opened my eyes. A barely-conscious demon serving the worst deity alive, imprisoned in a nightmare realm where death waits around every corner. Most would surrender immediately. I refuse to quit. I've learned to survive with what fate provides, no matter how cruel. This insane new world won't break me—not when I've already tasted death and returned. Every monster, every boss, every trap is just another obstacle to overcome. The odds are stacked impossibly high, the bosses ridiculously overpowered, but I'm still standing. Still fighting. And I'm far from finished.
