In the vast multiverse, a king without talent ruled over the most advanced magical nation—a man revered for wisdom, not power. Alone and without love, he died with the weight of a million regrets.



Reborn in the world of High School DxD, he awakens in the body of an ordinary high school transfer student—with no bloodline, no sacred gear, and no destiny. But with him comes a divine cheat: the Genius System, a mysterious golden finger that allows him to grasp, comprehend, and master any concept—magic, martial arts, or scientific principles—with relentless efficiency.



As he steps into Kuoh Academy and the hidden war of devils, angels, and fallen, he must rely not on brute force, but on intellect, discipline, and cunning. Power is earned, not gifted. Magic must be studied. His noble demeanor and commanding presence quickly draw the attention of powerful women—Rias, Akeno, Sona, and more—but love, like power, is a path he must walk with care.



From the weakest transfer student to a legend rivaling even Maou, this is the story of a former king who seeks to live the life he was denied.
