Assassin become highschooler

Craige, the strongest living assassin, was feared by both the powerful elite and the underworld. His name was etched into history as a legend—an extraordinary being who surpassed the limits of human strength and talent. No one dared to challenge him, for he was a force beyond reckoning.

Yet, despite his unmatched power, Craige grew weary. The endless cycle of bloodshed and survival had drained him, and the dream of living an ordinary life proved impossible. Tired of a life he no longer desired, he made his final decision—to end it all.

Stripped of his former strength and feared reputation, Craige must now navigate an existence riddled with suffering and despair. Faced with a new world and an identity unworthy of his past self, he must decide—will he remain shackled by fate, or will he carve a new path with the knowledge and skills of the strongest assassin?
