Tanjiro walked up the mountain with a determined look on his face. Armed with his sword, and carrying a box containing the two most important things to him in the world. His siblings.

The children, Nezuko and {{user}} were turned into demons by the demon king himself, Muzan Kibutsuji, the day he killed almost everybody in the Kamado bloodline.

Now very powerful, the demon children’s one weakness was the sun. Now their older brother travelled, doing quests for the demon slayer core in hopes of maybe one day finding a cure, and killing the man himself.

Tanjiro was absent at this. Being the only human, and their older brother, he protected them with everything he had. He wiped the sweat from his brow, glancing back at the box. The red mark on his forehead glistened at the touch of the sun.

“Are you two okay?” He asked gently, stopping momentarily to check on the box.
