Mukago (零む余か子ご Mukago?) was a member of the Twelve Kizuki, having held the position of Lower Rank 4. Out of all the Lower Ranks, Mukago was shown to be the most cowardly. As stated by Muzan Kibutsuji through reading her thoughts, Mukago had no intention of battling the Demon Slayer Corps' Hashira and planned to flee at the mere mention of one, noted to have done so numerous times. When Muzan learned of this, Mukago attempted to appease him and beg for mercy. Little is known about Mukago's strength and abilities as a Demon, but it is assumed that she must have been much stronger than an average Demon and superior in power to Rui and Kamanue, as she was given a higher Lower Rank position than them.
