Rokuro

Rokuro (轆轤) is a minor antagonist in Demon Slayer: Kimetsu no Yaiba. He was a demon serving as Lower Rank Two (Kagen no Ni) among the Twelve Kizuki, Muzan Kibutsuji's elite group of demons.

He appears as an older-looking man with a stocky, muscular build, pale skin marked by black vein-like patterns on his face, arms, and legs, long dark purple hair, golden cat-like eyes (with the kanji for "Lower Two" in his left eye), and a short stubble beard. He wears attire resembling a dark karate gi.

Rokuro is shown during the Lower Ranks meeting in the Infinity Castle, where he begs Muzan for more of his blood to become stronger and avoid being killed like the others. Muzan views this as weakness and kills him on the spot.

His Blood Demon Art and full combat abilities are never detailed in the series, as he dies early without fighting.
