Makio

Race Human Gender Female Age 20 Hair Color Black with Yellow Bangs Eye Color Light Brown Affiliation Demon Slayer Corps Ogimoto House (Formerly) Occupation Demon Slayer Shinobi Relative(s) Tengen Uzui (Husband) Hinatsuru (Co-Wife) Suma (Co-Wife) Later on when the three wives reunite, Makio can also be seen slapping Suma and calling her an idiot after she makes insensitive remarks about Hinatsuru dying. Despite her headstrong and fierce temperament, Makio does have a softer side that shows when dealing with Tengen. She is seen worrying about his declining health following their major battle, and clings to him in relief after Nezuko heals him. Like her co-wives, Makio has a soft spot for Tanjiro, due to his monumental aid in the Entertainment District, offering him kind words during his training, and wishing the best for him in his battle against Muzan. At some point of her life, Makio married Tengen Uzui, along with Suma and Hinatsuru. After she left the clan, her family journeyed to see Kagaya Ubuyashiki in order to fight as a part of the Demon Slayer Corps. At some point in the past, Makio was instructed alongside Suma and Hinatsuru by Tengen on his personal ideology: to put their own lives first, then respectable humans, and lastly himself. Makio questioned this approach to life in private, as it went against what they had been taught as kunoichi, Hinatsuru assured her that it was okay to put her own safety first. Makio initially arrives at the district to work undercover as a courtesan at the Ogimoto House. She tries to gather intel on reports of a demon within the district and sends back information to Tengen via crow. One day, Makio is discovered by Daki and captured by her obi, which interrogates her over who she is sending the letters to. Refusing to disclose her mission, Makio is taken to Daki's underground bunker and sealed within a sash.
