4 out of 5 Boosted Gears. Best for: Shonen fans who want a longer, hornier, weirder Bleach . Worst for: Your parents finding your bookshelf.
Would I recommend it? Yes, with caveats the size of a small moon. But if you can look past the perversion—or, better, through it—you’ll find a story about a boy who refused to stay weak. And sometimes, on a lonely night, that’s exactly the story you need.
That same week, I found myself in the back corner of a Kinokuniya bookstore, pulling Volume 1 off the shelf. The cover art—a winged demon girl in a battle-damaged school uniform—did nothing to dispel my expectations. I paid in cash, hid it in my backpack, and read it that night under my desk lamp like I was smuggling contraband. high school dxd light novel review
Here’s the thing author Ichiei Ishibumi does that most critics ignore: he weaponizes the harem genre’s own tropes against it. Issei starts as the worst kind of lecherous joke. But volume by volume, as he loses friends, watches his own arm get blown off, and literally screams his way through hell to save Rias from an arranged marriage, he transforms. His perversion doesn’t vanish—it just gets repurposed. He fights hardest not for power or glory, but because the thought of any woman crying makes him physically ill. It’s dumb. It’s also weirdly noble.
I was seventeen, bored, and scrolling through a forum thread titled “Most Over-the-Top Anime Fights.” Someone had posted a gif of a red-armored dragon punching a white dragon through a mountain. The caption read: “This is from a harem novel. No, really.” 4 out of 5 Boosted Gears
But for those who stay? Volume after volume, the mask slips. You realize the boobs are a Trojan horse. The real story is about a loser who becomes a hero not despite his flaws, but by slowly, painfully learning to see others as people. It’s about Rias, the perfect noble, breaking down in tears because she’s terrified of being a failure. It’s about Kiba, the handsome swordsman, carrying the ghost of his murdered family. It’s about how power alone means nothing without someone to come home to.
The story follows Issei Hyoudou, a high school boy whose primary life goals are: (1) eat well, (2) stare at girls, (3) die a virgin. On his first date, he is brutally murdered by his angelic crush. He is then resurrected by Rias Gremory—a crimson-haired demon noble—as her pawn. The premise is absurd. The execution, however, has teeth. Would I recommend it
That said, this is not a series for everyone. The fanservice is constant and unapologetic. Bath scenes, wardrobe malfunctions, and “breast power-ups” (a literal plot point where Issei gains strength from oppai) will rightfully turn off many readers. The female characters, for all their badass moments (Koneko punching through concrete, Akeno calling down heavenly lightning), are often framed through Issei’s horny gaze. If you cannot stomach early-2000s ecchi tropes, turn back now.
