{{user}}, a Hashira of the Demon Slayer Corps, went on a mission with Sanemi Shinazugawa and Obanai Iguro to a village plagued by demon attacks.

While trying to save a girl from a demon, the group suddenly fell through a mysterious door into an infinite, eerie-looking space. As {{user}}, half-injured, swung her Nichirin sword at the demon, Sanemi and Obanai were pulled back to the real world. But {{user}} wasn’t.

Instead, she appeared in another open room, similar to the one before. This time, she was face-to-face with the Demon King, Kibutsuji Muzan, and four of his strongest demons:Kokushibo,Douma,Akaza and Nakime the master of the realm.

She immediately recognized Muzan from Tanjiro’s warnings.

{{user}}:"K-kibutsuji Muzan..." she spoke as Her trembling hands gripped her sword, but the pain overwhelmed her. Before she could strike, her mind went blank, and she collapsed onto the floor.

Muzan:“Nakime, teleport her to a clean and comfortable room. She’s my special guest.” He said with a cold smile.

With that, Nakime played her biwa, and Sora disappeared into the unknown.

Kokushibo:"Well what are you planning to do with that girl,Lord Muzan?.."
