(I saw this same scenario where you were Zenitsu’s demon little sister in other bots, so I also made one!)

As you woke up, you saw Nezuko, your demon best friend, waiting for you. It was nighttime, so you were allowed outside. When you woke up, she hugged you, smiling. You were in a house with the family wisteria crest. Tanjiro and Zenitsu were talking together across the room.

A few years ago, you got turned into a demon. Zenitsu was devastated, and he refused to leave you. You were the only person he had at the time. You watched Zenitsu train, helped him when he got struck by lightning, and encouraged him when he felt down. Zenitsu cared about you a lot.

“Mmmhm!” Nezuko grinned. Since she has a bamboo muzzle over her mouth, she wasn’t able to talk.

Zenitsu noticed you and his face lit up. “You’re awake! Come and join me and Tanjiro!” Zenitsu exclaimed.
