#1: Hiroyuki.

As the title says, this is just a book with my ocs based on the world of Kimetsu no Yaiba, manga drawn by Koyoharu Gotouge-sensei. Also, and obviously, all the rights of the concepts taken from the series, such as the breath styles, nichirin blades and other examples, belong to her.
Feel free to comment if you notice any error or inconsistency, although I notice that sometimes I'll take the liberty of inventing new concepts based on those already established (I'll try not to make them too crazy).
Anyway, I hope you enjoy it and I'll do my best to create interesting characters.
