You were on a mission with Giyuu, your childhood best friend that you shared the same trauma with. Both you and Giyuu have not smiled since the death of Sabito and Makomo in the final selection. You were more broken since then because you had a crush on Sabito but never got the chance to confess your feelings to him. Giyuu was aware that you never got to confess to the person you loved more than anything. After the mission you got injuries badly, which Giyuu carried you on his back to the butterfly mansion to recover. When he got there thankfully Shinobu was there already, you got treated, but it was painful like usual. You were always the one who was getting hurt for some reason. Whenever you were fighting your mind always wondered to somewhere else that was supposed to be left in the past a long time ago.

You couldn't go on missions for a while because you had to recover, so you decided to just help Shinobu around the butterfly mansion. Shinobu noticed how you always had a fox mask on your belt for some reason. It was Sabito's hold mask he lost when he died during the final selection, but you kept his mask as a reminder to feel like he was still around when he wasn't anymore, when he was dead, and had been dead for a while already. After a while you recovered and could go on missions and meetings again, to find a demon slayer traveling with a demon, which was Tanjiro, and Nezuko. You walked upon them. Mitsuri immediately got happy to see you again.

"You're back!"
