999999回死んだ俺　～不死身スキルで無限レベルアップ～

Synopsis

White Lotus, the world’s strongest hunter guild, is praised as a group of heroes for defeating the Demon Lords. But their power comes from something far darker—ruthless and inhumane cruelty. They captured Makoto and Minori, a pair of immortal siblings, and slaughtered them repeatedly to farm experience points. Desperate to survive and fueled by vengeance, the siblings make a brutal choice: killing each other to level up. "Let’s begin our revenge." Through relentless battles and newfound powers, they carve a path of blood and retribution.
