Mukago

Mukago is a minor antagonist in Demon Slayer: Kimetsu no Yaiba. She was a member of the Twelve Kizuki (the elite group of demons serving Muzan Kibutsuji), holding the position of Lower Rank Four (Lower Moon Four).

She appears briefly during the Lower Ranks gathering in the Rehabilitation Training Arc, where she is shown to be extremely cowardly and fearful—more so than the other Lower Moons—despite her relatively high rank among them. Mukago begs for her life and avoids confrontation, which ultimately leads to her being deemed useless by Muzan and killed by him on the spot.

She has a petite build, light gray/pale skin, white hair with shorter bangs, white horns on her forehead, two dark red stripes across her cheeks, and distinctive eyes (gray with white rings and dark red sclera, with the kanji for "Lower Four" in her left eye).
