Demon Slayer: Karina – The Arcane Slayer
In a world ravaged by demons, where the Demon Slayer Corps fights desperately to maintain balance, a new warrior emerges from a distant land: Karina, master of the mysterious Arcane Breathing.
Her style is unknown, her power disrupts even Upper Rank demons, and her past remains sealed behind a secret mission—evaluate the true threat posed by Kibutsuji Muzan.
Upon arriving in Japan, Karina is immediately thrown into one of the most dangerous battlegrounds: the Entertainment District, where countless disappearances shake the Corps. Tengen Uzui leads the investigation… but Karina’s sudden insertion into the mission changes everything.
Her strange aura, precise yet overwhelming technique, and sharp presence draw both trust and fascination. Tanjiro, Inosuke, and even Tengen begin to see her as a formidable force capable of confronting the deadliest demons of the night.
But Daki and Gyutaro, the Upper Rank siblings, sense instantly that she is no ordinary slayer.
She is a threat.
She is an anomaly.
She is the variable that could break their centuries-long domination.
This explosive What-If retelling of the Entertainment District Arc reshapes every battle, every revelation, and every choice.
Karina will confront the shadow of a tragic past, survive the advances of powerful allies drawn to her strength, and unleash an ultimate technique capable of slicing through illusions, arteries, and even the destiny Muzan imposes upon the world.
One thing is certain:
this time, history will not unfold the same way.
