Summary:

A human soul dies in a forgettable world and wakes up in the body of a forgotten prince. Not as the destined pervert hero, but as Sairaorg Bael, the so-called failure of the greatest destruction clan in Devil history. No Demonic Power, no sacred gear, no cheat harem system. Just a brutal body, a stubborn will, and one absurd new talent: Anti-Magic.

In a world built on spells, bloodlines, and sacred gears, his power does the one thing no one expects. It erases magic.

There is a catch. His Anti-Magic can only negate what he can match. If an enemy’s power outclasses him, their magic tears right through. To climb high enough to cancel the monsters that rule this world, he needs fuel. Not training montages, not meditation apps, but meat. The flesh of rare monsters from the deepest hells of every religion.

So Sairaorg’s second life becomes a grind.
Hunting dragons that breathe storms.
Wrestling beasts born from punishment and myth.
Cutting deals with ancient rulers of the dead.

He throws himself headfirst into underworld politics and monster ecology, forming unlikely bonds with beings who should be nightmares. A dragon king that eats typhoons as snacks. Yama, a god of the underworld who weighs sin and potential in the same hand. Some become allies, others become rivals, all of them circling the same prey he needs to grow.

At home, the Bael clan writes him off as a cripple. To them he is a powerless heir with no Demonic Power and no future. Sairaorg has other plans. He begs for a senjutsu instructor, digs into the most grueling training imaginable, and fuses that life-force art with his natural aura, evolving his touki into the first true Anti-Magic in Devil history. Every step forward burns his body, shreds his nerves, and stretches his soul. Every victory buys him one thing. Rank.

The stronger his rank, the more magic he can erase.

Parallel to canon, his path quietly bulldozes fate. In this life, he refuses to watch people break the same way they did before. When he stumbles into Akeno and her human mother’s tragedy, he does not walk away. He shatters the script. With raw fists and Anti-Magic-fueled touki, he crashes the scene that was meant to ruin them, dragging them both out of a future of loss.

Akeno grows up looking at him with storm-filled eyes and a secret smile, half vengeance, half worship. Her mother sees the same boy, but with the soft gratitude of a woman whose life was returned by a stranger. Neither of them knows the other is in love with the same man. Both of them decide to win him, and both are far too proud to back down.

Koneko’s story twists too. When the world tries to crush her and her sister, it finds a Bael standing between them and the darkness. To Koneko, Sairaorg is not just a savior. He is proof that hard work can punch destiny in the face. She is blunt, small, and completely uninterested in playing shy. While everyone else plots and flirts and spirals into awkwardness, Koneko just asks for what she wants. She is the first to cross the line no one expects, the first to pull the supposedly stoic Anti-Magic King into bed, without fireworks or dramatic speeches. Just honesty, and a very confused morning after.

Sairaorg does not stumble around like a clueless protagonist. He is surprisingly smooth. Not because he is a natural playboy, but because he treats even goddesses like people. He listens. He flirts back without shrinking. He respects boundaries and still refuses to be emotionally distant. That rare mix turns his saved heroines into active pursuers.

What starts as hidden crushes becomes open warfare. Akeno dropping “accidental” seductive scenes into training sessions. Her mother escalating with mature charm and domestic ambushes. Koneko clinging to him with deadpan boldness that shocks everyone else. All of it orbiting a man who just wanted to get strong enough to rewrite a bloody future, and now has to juggle kisses, jealousy, and murder beasts between classes.

Then comes the turning point: Rias Gremory’s engagement to Riser Phenex.

This is supposed to be the original hero’s call to action. Instead, it becomes Sairaorg’s declaration of war on every arrogant noble who ever looked down on him and his mother. When Riser insults them in public, Sairaorg does not swallow it. He challenges Riser on the only battlefield the devils respect: a Rating Game.

If Sairaorg wins, the engagement breaks.
If he loses, he becomes the joke every great house retells for centuries.

With a peerage built through sweat instead of bloodline gifts, Anti-Magic that eats Phoenix flames once he claws high enough to reach them, and strategy sharpened in a hundred monster hunts, Sairaorg steps into the arena. The Underworld expects a humiliation. What it gets is a revolution.

When he crushes Riser, the world tilts.
Rias is free.
The Bael “failure” is suddenly the most terrifying new piece on the board.
And the solution everyone scrambles toward is simple. Tie him down.

Rias’s family proposes a new engagement. Sairaorg accepts, not as a trophy, but as a partner. Their relationship begins as a political alliance and grows into something louder and messier. Rias is proud, fiery, and too intelligent to play the background. She falls for the man who ripped her strings off, even as she has to share him with the women he saved long before she met him.

The story follows Sairaorg from childhood in the Bael estate to high school chaos in Kuoh, as he slides into Issei’s old role while refusing to be anyone’s replacement. He still crashes into Fallen Angel plots, still breaks through the politics of Devils, Angels, and Youkai, but every event bends around his Anti-Magic, his senjutsu discipline, and his strange network of underworld allies.

He defeats enemies by erasing the advantages they never imagined losing.
He negotiates with beings no Devil prince should meet alone.
He keeps eating, fighting, and laughing through scars that would break lesser men.

All while a harem comedy brews around him.

Girls fight over training slots, over cooking for him, over who gets to sleep beside him after brutal battles. Akeno and her mother wage a quiet war of seduction that constantly blows up into loud, ridiculous confrontations. Koneko wedges herself into his side and deadpans threats at anyone who dares push her out. Rias struggles to balance her pride as a Gremory heiress with the ache in her chest when she sees him holding someone else.

Through it all, Sairaorg refuses to lose himself. He builds a family out of misfits and survivors, crafts a power that erases the unfair advantage of bloodlines, and walks a line between hero and monster with deliberate, stubborn steps.

“Anti-Magic King: Reborn as Sairaorg Bael in High School DxD” is a high-energy blend of power fantasy, harem comedy, and emotional character drama. It is about a boy who rises from weakness to change a world obsessed with talent and blood, using nothing but fists, Anti-Magic, and the wild, inconvenient love of the girls who refuse to leave his side.
