Mukago (lowermoon 4)

Appearance
Mukago was a petite, fragile girl with sickly yellowish skin. Two dark red stripes ran down her cheeks, and two white horns protruded from either side of her forehead. Her eyes were gray with white rings, dark red sclera, and the characters for "Lower Moon Four" carved above her left iris. Long eyelashes framed her gaze. Her chin-length white hair had short bangs between her horns. She wore a simple red kimono with a collar trimmed with black and white fur, tied at the back with a large dark purple bow.

Capabilities
Little is known about Mukago's demonic abilities. It is believed that, since she achieved the position of Lower Moon Four, she was significantly stronger than the average demon, surpassing Rui and Kamanue in power. However, in the story, she never demonstrated these powers in combat.

Despite her high rank, Mukago proved to be the most cowardly of all the Lower Ranks. Muzan, who could read the minds of the demons with whom he shared blood, learned that she had no intention of fighting the Hashira (Pillars) of the Demon Slayer Corps and planned to flee at the mere mention of encountering such an adversary. When she desperately tried to convince him of her loyalty, declaring that she was willing to risk her life for him, he considered this a contradiction in terms.
