I bought volume one of the manga and was very dissapointed, so I decided to start watching the anime on Youtube instead.
Dissapointed in what way?
I guess I'm just not a manga kind of guy. Basically, it was dead on to the episodes I had already watched, the animation was in black and white and subpar at best(action scenes), and it didn't really pull you in as much because you can't get a feel for the characters like you do in the anime.
I guess what I'm trying to say is, if I want to read something, I'd grab a book.
