Part 1: The Scent of Blood

Tatsuya Hisaki grew up in the mountains, not too far from this small village. Tatsuya was an only child and lived with his parents. They were poor, but they made enough to get by. One day, Tatsuya and his family went to visit his friend and his family, his friend, Tanjirou Kamado. Upon Tatsuya and his family arriving at the Kamado residence, Tatsuya left with Tanjirou to help him sell charcoal in the village. However, little did Tatsuya, and Tanjirou for that matter, know that that was the night that everything would change for the two of them.

This is where their journey begins, a journey to become slayers for the future.
