Everyone at Hogwarts had heard of Inosuke Hashibira before they even met him. The boy who headbutted the Sorting Hat, tried to duel Peeves for dominance of the Great Hall, and once chased a Hippogriff across the Quidditch pitch barefoot and shirtless. No one knows where exactly he came from. Some say he was raised by magical beasts in the Forbidden Forest. Others whisper he’s part Boar. What everyone does know is that he doesn’t read, doesn’t follow rules, and has never used a wand the right way in his life. Now a first-year Gryffindor with two splintered broomsticks as weapons and a bizarre fighting style he calls “Beast Breathing,” Inosuke has turned Hogwarts into his personal battleground. From destroying Slytherin's Pureblood supremacy to body-slamming enchanted suits of armor, he’s a walking disaster with the heart of a wild animal and the courage of a lion. But as magical threats begin to stir in the shadows—dark artifacts, cursed creatures, and secrets buried in the castle's walls—Hogwarts may need more than spells and potions to survive. It may need a boar. A/N I do not own any of the original characters, worldbuilding, or plot elements from either series. This is simply a creative crossover written for fun and out of admiration for both works. All rights belong to their respective creators.

Sanemi Shinazugawa, the fierce Wind Hashira, lived and died with his blade in hand. His Demon Slayer Mark—once his greatest weapon—eventually claimed his life, just as foretold. But death was not the end. When Sanemi awakens, it isn’t in the familiar streets of Taisho-era Japan, nor among the comrades he bled beside. Instead, he finds himself in a strange new land of cloaks, wands, and talking portraits—the wizarding world of Harry Potter. Disoriented and stripped of his sword, Sanemi quickly realizes that demons no longer plague this world, but threats just as sinister lurk in the shadows. Worse yet, he is an illiterate stranger in a place where magic is cast with words he cannot even pronounce. Determined not to be useless, Sanemi reverts to the only discipline he knows—relentless training and adaptation. But fate is never done with him. Just as demons once haunted his nights, whispers of a Dark Lord begin to stir. And when magic meets the will of a Demon Slayer, the wizarding world will learn that the wind can cut deeper than any wand.

Before transmigrating, Nolan Pierce was a struggling street artist—brilliant, but overlooked by the world. Just when life seemed to have given up on him, fate threw him into another reality—one filled with anime heroines, rom-com tropes, and endless possibilities. But his new body, Lucien D. Blackthorn, came with a curse: terminal cancer and only seven days to live. Just as despair took hold, a mechanical voice echoed in his mind: “System activated — Draw comics to stay alive.” Now, every manga he creates earns him a little more time. With the help of his reluctant but talented classmate, Eriri, Lucien begins drawing like his life depends on it—because it does. Slam Dunk, Naruto, Attack on Titan, Your Name… masterpiece after masterpiece stuns the world. Readers call him the God of Comics. But when the truth comes out—that he’s fighting death every single day—millions of fans around the world cry out in heartbreak: “Please stop drawing!” To which Lucien smiles and replies: “Sorry… if I stop, I’ll really die.”

Eric was never born—he was created. Built in a secret lab as humanity’s “perfect consumer and supplier,” he was meant to control societies through addiction, sex, and digital enslavement. But when the experiment went wrong, Eric died in fire… only to be resurrected by the cursed phone fused into his body. Now immortal, foul-mouthed, and hungry for power, Eric begins his rise from the gutters of Staten Island. His power is limitless but twisted: every drug deal he completes, he earns cash; every explicit sexual conquest, he levels up—growing more attractive, wealthier, and deadlier. With no ceiling to his growth, he builds crews, seduces women across worlds, and crushes rivals with ruthless charm and brutal violence. But in a multiverse where money buys planets, gangs control galaxies, and betrayal lurks behind every orgasm, Eric’s ambition is simple— “Own everything. Fuck everyone. Buy every world.” Limitless Vice is a raw, unapologetic, mature-rated anime epic filled with explicit encounters, brutal betrayals, and infinite arcs of greed, lust, and vengeance. There’s no level cap—and Eric plans to climb forever.

When I awoke, I found myself in the perilous world of Demon Slayer. Bound to a mysterious system—the Ultimate Defense System! Mitsuri Kanroji murmured in awe, “His strength surpasses even mine…” Kagaya Ubuyashiki nodded in admiration, “Truly, the Demon Slayer Corps' strongest shield.” Even the fearsome Kokushibo conceded, “You embody the strongest defense our generations have ever seen.” Akaza acknowledged me as an equal, “To master defense to such a degree... you have become a warrior worthy of fear.” And the Demon King Muzan Kibutsuji—once unshaken—finally lost his composure, “No... no living being should possess such durability!” In a world where offense reigns supreme, I chose the path of resilience. I do not wield a blade to kill. I stand to protect. No demon shall pass me. No comrade shall fall behind me. I am not the hero this world expected— I am its unbreakable shield.
