Demon Slayer: My Breath Technique Mutated

[Genre: Casual, Zero Grind, Harem, Pure Chaos] | [Faction: Demon Slayer Corps (Carried Hard)]

While ordinary slayers spend years pushing their bodies to the absolute limit through agonizing training, Shirakawa Haru discovered a much better shortcut to infinite power. His training regimen? Walking up to the prettiest girls in the Corps and asking a simple question:

"Excuse me, may I get a quick sniff?"

Shinobu Kocho immediately flashed her signature sweet smile, raising a vial of lethal wisteria poison: "How many times would you like to experience death today, Yu-kun?"

Meanwhile, Nezuko just poked her tiny head out from behind, her big pink eyes blinking in utter confusion at the absolute degenerate standing before her.

Fast forward to the brutal final showdown in the Infinity Castle. Faced with the overwhelming, world-crushing pressure of the Demon Progenitor, Kibutsuji Muzan, the entire Corps is on the brink of despair. But Shirakawa Haru? He just takes a deep, appreciative breath, standing proudly amidst his harem of elite swordswomen.

A blinding, neon-pink aura erupts from his body, piercing straight into the sky as he points a finger at the ultimate evil:

"Yo, Muzan! I dare you to pull up in the dress again!"
