The Hero Trained by the Worst Demon King Is Unrivaled in the School of Returnees From Another World Manhua

Title: The Unrivaled Hero In a world where heroes are revered and admired for their unique skills, Kujou Kyouya stood out for all the wrong reasons. Lacking the special abilities that others possessed, he failed to save his world from destruction and was labeled as a "failed hero" at the prestigious interdimensional academy where heroes from various worlds converged. Despite the mockery and disdain he faced, Kyouya harbored a secret: he had spent 30,000 years training in another world with the most feared and evil demon king, Felice. Together, they had faced unimaginable challenges and conquered countless foes, with Felice imparting his unparalleled combat knowledge to Kyouya. Through this intense training, Kyouya had honed his skills to perfection, surpassing even the strongest heroes in the academy. His newfound power was a force to be reckoned with, a testament to the unorthodox methods of his demonic mentor. As Kyouya's legend spread throughout the academy, whispers of his unparalleled strength and unmatched abilities echoed through the halls. Students who once scorned him now looked on in awe and reverence, realizing that the "failed hero" was, in fact, the most powerful of them all. With each battle he won and each challenge he overcame, Kyouya's reputation continued to grow, cementing his status as the unrivaled hero trained by the worst demon king. His journey was far from over, and the trials that lay ahead would test his strength, his resolve, and ultimately, his destiny as the savior of not just one world, but many. The tale of Kujou Kyouya, the unlikely hero forged in the fires of adversity, had only just begun, promising epic battles, heart-wrenching betrayals, and a destiny that defied all expectations.
