The Underworld Transcendent Returns

Leon Klein, the Grand Mage who vanquished the Demon Lord and saved the world, is betrayed by Prince Schalk. After revealing that he has burned down the orphanage Leon holds dear, Schalk casts him into a lightless abyss. For ten grueling years, Leon survives in this subterranean hell, battling endless hordes of monsters and mastering enigmatic spells fueled entirely by his thirst for revenge. When he finally claws his way out of the darkness, Leon awakens not as himself, but in the body of Ren Kuroba, a bullied teenager attending the prestigious Seio Academy. As he navigates the challenges of this unfamiliar life, he makes a chilling discovery: Prince Schalk is also present at the academy, quietly advancing his sinister agenda from the shadows. Though his name and face have changed, Leon’s relentless pursuit of vengeance remains exactly the same.
