Mitsuri Kanroji (甘かん露ろ寺じ 蜜みつ璃り Kanroji Mitsuri?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. She is a Demon Slayer of the Demon Slayer Corps and the Love Hashira (恋こい柱ばしら Koi Bashira?).
Mitsuri is a young curvaceous woman with fair skin and round, light green eyes with long eyelashes, a small mole beneath each of them. She has long, pink hair that fades into a neon green color at the halfway point, which she wears in three thick braids with five shorter clumps hanging over her face as bangs. When she was trying to get married, her hair was dyed black in an attempt to make herself look more "normal."
Mitsuri wears a modified purple tinted version of the standard Demon Slayer uniform along with a plain white haori that was gifted to her by Kyojuro Rengoku. The chest area of her uniform is left unbuttoned and she wears a short skirt in place of the usual hakama pants. Additionally, she wears a pair of navy blue thigh-high socks layered with the striped lime-green socks Obanai Iguro gave to her and a pair of white zōri with pink straps.
While at the Swordsmith Village, Mitsuri wore a kimono with floral designs.
During her and the other remaining Hashira's fight against Muzan, Mitsuri's left and back braids are cut off by Muzan Kibutsuji's attacks, now shortened to shoulder length, and part of her left ear is also torn at the side. Mitsuri also loses both of her arms in the process of ripping out Muzan's left arm clean off.
Obanai Iguro (伊い黒ぐろ 小お芭ば内ない Iguro Obanai?) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the Serpent Hashira (蛇へび柱ばしら Hebi Bashira?).
Obanai grew up in a family with only females, and was fed and kept alive so that he could be fed to a Serpent Demon. Once he realised this, he immediately conceived a plan to escape, by scratching at the walls he was imprisoned in, it was also where he met his friend snake, Kaburamaru (鏑かぶら丸まる Kaburamaru?). When he escaped, he was chased down by the Serpent Demon who had killed all the members of his family earlier on, before being saved by the former Flame Hashira, Shinjuro Rengoku.
Afterwards, he decided to join the Demon Slayer Corps in hopes that he could cleanse his corrupted blood and live a normal live. Obanai also has a crush on the Love Hashira, Mitsuri Kanroji.
