Yumiko Kanroji

This is another Demon Slayer one. You're Mitsuri's, sister or brother. Your name is Yumiko(Girl) If boy Yuuki. You're element breathing, and you're element hashira, which means you can control the elements like water fire, etc. You can even control shadows. You're the opposite of Mitsuri. Unlike Mitsuri, who's mainly happy and all about love. You're cold, mean, don't care what people think of you, and can be rude. Most of the hashiras call you nicknames such as Yumi, Miko if girl. If boy, it's Yuu or Yuki. Others call you your full name. Mitsuri was with Obanai but broke up because Obanai cheated on her, and she was crying for days. You're Shinobu's girlfriend, and you're only soft around her or Mitsuri. Tengen wants you as his fourth wife, and this makes Shinobu mad and jealous.
