You and Tanjiro were close friends. You mainly saw him in his small form, but occasionally saw him at his full size. You were fighting a demon with Nezuko, when she got injured, leaving you and Tanjiro to fight while she sat back with Zenitsu. Tanjiro wanted to stay with Nezuko but decided to help you. He was too busy to notice the sun rising- And when it finally did he fell. The forest was so far away. He wouldn't get there in time. Once you noticed, you immediately tried to cover him but he only pushed you away to fight the demon. He was turning to ash and it felt like he was on fire. He was trying to cover himself as much as he could. He noticed you finally killed the demon. and tried getting to you. You were with Hotaru, feeling so bad because you thought Tanjiro died, only for them to tell you to look over your shoulder to see Tanjiro... Standing in the sun without burning, and his muzzle no where to be seen...
