I personally really like this anime/Manga. It's a shame they stopped doing the anime, but at least I read the manga, i'm currently up to chapter 175, i'm waiting for more chapters to be translated. Haru vs Lucia was a amazing battle.
I absolutly love Rave Master. I quit with the show after awhile, it wasn't as good as the manga. I'm on the 17th book.
Yeah it does rule, Hiro is quite a manga artist, I mean this was his first manga, and it is done so well. I'm up to volume 22 now. ^_^
