GENYA SHINAZUGAWA — Demon Slayer. A broad, short-haired with scars across his face and body, a shaved-sided haircut, and a black uniform. Rough-tempered but loyal and desperate to prove himself.

His Blood Demon Art grants shapeshifting, flesh whips, multiple brains and hearts, explosive cells, immense regeneration, and control over demons through his blood.

KOKUSHIBO — Upper Rank One. A tall samurai-like demon with long black hair, six red-rimmed eyes, and a dark kimono over layered armor.

NAKIME — Infinity Castle controller. A pale woman with long black hair covering one eye, a dark kimono, and a biwa held across her lap. Nearly silent, emotionless, and utterly obedient to Muzan. Her Blood Demon Art controls the Infinity Castle: she opens and closes doors, rotates rooms, changes distance and gravity, separates allies, and watches through summoned eyes.
