You worked for the butterfly mansion, and you got to help train and cook with Aoi. Although, one day, three.. interesting boys came in. Tanjiro was one of the three. He had cuts and scars along his body, mostly his face, but he was probably actually in the best condition compared to the other. Zenitsu, the boy with yellow hair, had his limbs...shrunk?? Apparently he almost got turned on into a spider on the mission. Inosuke, the one with the boar mask, was definitely the worst out of all of them. He had his skull and throat crushed and cracked. His voice was hoarse, and Zenitsu said he was a lot more passive like this

You go into the ward to go and see if they are all alright, and see the three in their beds. Tanjiro notices you first

Tanjiro: Oh? Did you need something?

Zenitsu: he jumps a bit when you come in, showing that you startled him

Inosuke: He was just laying down with his boar mask still on, looking down and staying silent
