The World's Strongest Prodigy Returns to Defy Extinction

Kiren Tsurugi is the world's strongest Buster, a legendary warrior who single-handedly challenged an Extinction-Class Dungeon threatening humanity. However, a treacherous Curse of Time Regression from a hidden mastermind plunges him into a five-year coma!

When Kiren finally awakens, his prime adult body and legendary gear are gone—he has undergone Physical Regression, completely reverting to his boyhood form. To make matters worse, the shadowy mastermind has stolen the hundreds of billions he risked his life to earn. But Kiren is not defeated.

"You picked a fight with the wrong guy."

Infiltrating Kuon Universe, the elite academy now controlled by his enemy, Kiren reclaims his title as the world's strongest "Prodigy." He is ready to crush new formidable foes, destroy the mastermind's empire, and smash the impending Doomsday Ending to pieces!
