Maka

I read the first manga bc me and my stepdad were at a book store and there was an anime section and I've seen like 4 seasons (still working on finishing) of MHA, I wanted to get the mangas, there was no book 1. I heard of Demon Slayer, THERE WAS NO BOOK 1. my stepdad saw Soul Eater and told me about it. I got the first manga and now I wanna get all of them ;-;
