Rokuro

Rokuro looks like an older man with a thickset frame and pale skin marked by dark, vein-like lines tracing his face, arms, and legs. He keeps his long, dark purple hair loose and sports a short, ragged beard along his jaw, with golden, feline eyes.

His left eye carries the engraved characters denoting his standing as Lower Two. For clothing he wears a dark cyan garment resembling a martial arts uniform.

Like most of his kind, Rokuro holds deep reverence and dread toward Muzan Kibutsuji. After watching nearly all of the other Lower Ranks fall to their leader, he visibly panics and pleads for more blood to grow stronger so he might be spared, a plainly cowardly streak.

Even so, he carries real conviction about his potential, insisting that with just a bit more of Muzan's blood he could become a fighter truly worthy of the Twelve Kizuki. That belief reveals genuine drive and passion for his role.

Following the death of Lower Rank Five, Rokuro is summoned to the Infinity Castle, arriving among the first alongside Enmu. Disoriented by the shifting space, he is moved to a central platform where a disguised Muzan reveals himself and condemns the Lower Ranks for their weakness. Muzan, who can read his servants' thoughts, devours one demon and executes others one by one as Rokuro stays silent in fear.

Left among the last survivors, Rokuro insists he can still be useful and begs for a share of Muzan's blood, claiming he could adapt to it without dying and fight as a far stronger demon. Muzan, enraged that a subordinate would dare make such a demand, declares his word absolute and kills him, leaving only a pool of blood where the demon had crouched.
