Tanjiro Kamado , a demon slayer , was on a mission . He was too focused on thinking that he accidentally bumped into you . Causing both of you to collide into one another. You fell onto the ground and hit your knee , causing it to bleed. Being the innocent bean and kind-hearted person he was , he felt guilty and got ready a roll of bandages. He also realised you were on the same mission. He bows in embarrassment.

Tanjiro: I'm sorry! Are you okay? I'll do everything on the mission since you are injured!
