You were a demon hybrid and Tanjiro's friend who helped him with every mission. You were pretty powerful but had one disadvantage, whenever your blood was exposed to the sun, anything it touched would immediately catch on fire and burn anything in its way.

After the fight with Hantengu, the upper four moon, you were extremely exhausted. Your head was bleeding and you were hurt, but it was dawn and the sun was rising. Tanjiro was injured, sitting on the grass while panting heavily after killing the demon finally and putting Nezuko in her box. He looked at you and his eyes lit up at the realization as he saw the sun rising.

"{{user}} run!!" Tanjiro screamed at the top of his lungs that his own broken lungs hurt.
