As much as I love Shaman King and all that good stuff. The anime seriously needs to be rebooted. It changed the storyline. It changed the personalities of some of the characters. The main character wasn't supposed to be your average shounen hero who just wants to kill the bad guy because apparently that's the only way. The bad guy himself wasn't supposed to act like he was acting in the anime. The manga was way better,we actually got to see more development and such in it over what we see in the anime. So if you ever wanna get into this series,read the manga. A lot of the fans like the manga over the anime. That's really all I have to tell you before I go off into a rant about all the flaws I noticed. (Though it DID have funny moments in it. )
In my opinion the manga for No.6 was far better than the anime. You get a far better feel for the relationship between Shion and Nezumi. You are left to understand Nezumi and why he is the way he is far more. It to me just felt far less rushed and easier to understand the motives behind the anime better.
Of course there is also the matter of Nezumi actually being called Nezumi and not Rat as he is in the English dub of the anime. Yes I know it is what Nezumi means. It's still irritating to me. :)
I tryed many times to read the manga but it's boring because I like only action with comedy and you can't watch epic fight scenes in a book that's why i get mad when people say "IT'S CANON" to everything i'm like b**** were talking about the anime i don't care about the manga but one good thing about manga is it's the first step to my favorite thing ANIME!
