the books are actually a cheep rip off of the manga (that's not my opinion, it's from all the reviews i've read. i agree though)There's only one season, unless your talking about the two books, Digi.Ive watched it sence it came out.
And yes, it is really good.
Did you watch the english or japanese one? Japanese is better, english kills it.
yes, there are two season of the show. I own the two season box sets. there are 15 episodes a season I think it was, i can't quite remember. but there are two seasons, the cases that say season one and season two are my proof enough
Japanese of course XD english pretty much kills all anime, almost...sorta...pretty much.
