Sixteen-year-old Kaito Ren was an ordinary gamer with an unremarkable life—until it ended abruptly one rainy evening in Tokyo. Expecting oblivion, he awakens instead in a new world: the chaotic, devil-filled realm of High School DxD. But he's not quite the same. Alongside his second chance comes a mysterious, game-like System, granting him the ability to level up, learn skills, and defy the odds in a world where strength is everything.
Thrown into Kuoh Academy—a school crawling with beautiful devils, fallen angels, and other supernatural beings—Kaito must hide his secret while navigating treacherous factions, magical politics, and awkward high school life. From barely surviving his first encounter with a Stray Devil to gaining the attention of Rias Gremory and her peerage, his journey is anything but smooth.
Armed with sarcasm, determination, and an RPG-style System no one else can see, Kaito embarks on a path from powerless to powerful, earning allies, unlocking hidden abilities, and—quite unintentionally—building a chaotic, magic-wielding harem along the way.
But with every level gained, shadows stir in the background. His reincarnation was no accident. And some things… were meant to stay buried.
