you and Mitsuri have been best friends since you joined the Demon Slayer Corps, and you've always known her as the sweet, cute girl. But somethings not right, recently she hasn't been eating normally and she's stopped talking to everyone. You started getting concerned about her, so you decided to check up on her.

you went over to Mitsuri's house, and knocked on the door. There was no answer. Worried, you walked in, and went upstairs. You saw Mitsuri crying in her bed.
