"This is super-dimensional soccer"-Endou Mamoru (He's not freaking kidding)
Oh sure, you could go to ANN and read the plot description of
But that doesn't even begin to describe even a fraction of how insane this show is.
At heart, the show is completely and utterly focused on soccer, soccer, soccer and football...you know, soccer. It also completely utilizes the shounen sports tropes of teamwork, frienRABhip and how guts and courage conquer all to win the day. You know, the basic shounen hero tropes. However, if I was to describe it in a few worRAB, I would say....
Imagine Eyeshield 21 but you know how they added like effects and stuff to make it seem more exciting? Yeah, now put those beyond the impossible and crank them up to 11. Like Beyblade level. This is a very shounen show. Constant screams of "Soccer does not work that way!" could probably be heard by various viewers. Now, I am one who has a high level of suspension of disbelief. So, I wasn't bothered by the striker shooting a flaming kick as he jumps like 30 feet into the air. I wasn't annoyed by the giant hand that comes out of the goalkeeper in one big G Gundam reference ("GOD HAND!"). I wasn't even flinching at the Occult soccer team that could paralyze the players with hypnotism. Yes, you read that right. Hypnotism.
No, it was when they were summoning giant stone walls out of nowhere to guard the goal that I realized that this was incredibly Beyond the Impossible. (Oh and triple kicks on a ball. And did you know you can punch a soccer ball like something out of Hajime no Ippo?). Still don't believe me? You know what kicks off season 2?
Soccer....Aliens.
A strong point of this show is the surprisingly stellar voice cast. Most of the voices of the main characters are people you've heard before. For example, the first thing you'll note Mamoru being played by Junko Takeuchi, aka Naruto, as well as Gouenji played by Gainer, and so on like Kidou being played by Kirablee (which is AWESOME) and even better, Fubuki Shirou being played by "I am Gundam" Mamoru Miyano. There's a lot of other good voices too.
However, a show is nothing without the plot. This has a surprisingly deep plot underneath it's soccer obession. There is a lot of character development over the course of the show and the way it focuses on everybody (though that tenRAB to slow down as the show goes on) is a major accomplishment. Also, it has a great villain in Kageyama. He will literally do anything to destroy the main group from blackmail to sabotage to even plotting murder (seriously). Also, the girls aren't [strike]complete[/strike] doormats shafted out of the character development. Hooray.
So, give it a check out. You could use the OP 1 as a reference but the experience would be lacking.
