(As a note before I begin my review, I would like to point out that this discussion will be over all six volumes as an examination of the series as a whole. I include it on the page of the first volume since it seems appropriate here, as well asI can not attatch a review to a manga page.)
With the relations between manga and anime, they usually fall into one of three categories: mangas before the anime, anime and manga being released simultaneously, and the anime coming before the manga. The Eureka Seven manga series falls into the latter of the categories and while there is some relation between the two medias, a majority of aspects such as plot, characters, theme,and more do a complete 180.
Now in all fairness, there will always be some divergences from the original story, but these changes feel so unnatural that the story becomes more confusing with each chapter. I'll give you an example. In the third volume, which is where the manga waived bye-bye to the original story, we are introduced to a character who has some bitter rivalry with Holland Novak, claiming to be his eternal enemy for some past occurence between the two and literally dies at the end ofthe first chapter. My question is why make him some mysterious rival enemy type charactrer when you would only include him for one part of the story? Ray & Charles Beams were better adversaries to the crew of the Gekkostate that this twit. Not to mention how oddly different the ending is for the story. Without spoiling too much, instead of the Coralians being a kind and benevloent race who wish to co-exist with humans, they instead plot to destroy humanity to claim the Earth for their own.
I know things didn't make a whole lot of sense the first time around in the anime, but at least if you went along slowly you could absorb what was truly going on. In the manga, I have read it multiple times and am still confused as to why certain things were going on, especially in the last two volumes. Charactrers are different from their anime counterparts and again, while changes are to be expected, certain explanations for why characters behave as such is a little too farfetched, even for Eureka Seven. There is one scene where Eureka is literally possessed (or body snatched, I have no idea how it truly happened) and only till the very end do people go "Hey, Eureka sure is acting weird."
The majority of this series left a sour taste in my mouth,mostly due to me being such a huge fan of the anime. If you are a fan of the series, you cab give it a look but I doubt you'll like what you get. For those who are alien to the entire franchise, you can pick it up but you're better off with the anime. Come to think of it, with a franchise that has a slew of video games, two manga series, and a feature length movie, the only thing that was ever good was the anime.
Final Score- 2/5
