Rokuro

As with most demons, Rokuro greatly respected and feared Muzan Kibutsuji as his leader. After almost every Lower Ranks had been killed by the Demon King, Rokuro was visibly scared that the same would happen to him and resorted to begging his leader for more blood to increase his strength so he wouldn’t die, showing quite a cowardly demeanor. However, in spite of this, Rokuro appeared to be very confident in the potential of his abilities as a demon, since he claimed that if he received just a little more of Muzan's blood he could definitely become a strong fighter worthy of being in the ranks of the Twelve Kizuki, which showed he had a great resolve and passion for his role.

Rokuro had the appearance of an older man with a stocky build and pale skin that was decorated with black, vein-like patterns down his face, arms, and legs. He had long, dark purple hair that he left down, and a short, jagged beard around his jawline, as well as golden, cat-like eyes, with the kanji for |3=Ka}} and the daiji for |Ni}} was etched onto his left eye, which signified his position. He wore what appeared to be a dark cyan version of a typical karate gi.
