Hmmm... it's got potential to become a rather interesting series if it plays its' cards right. Will it be able to breath life into a bunch of cliches or will it turn into yet another dragged-out serialisation? So far, the direction of this series seems to swing from 1 direction to another.
What I really liked: the protagonist and some of the characters, the craziness of this manga(on the level of certain other mangaka), the art(character designs, the mecha designs and even part of the prison levels were kinda cool), that it's grim and gritty yet dosed with a pinch of light-heartedness so things are fairly balanced, the secrets everyone seems to hold and how almost everyone really struggles to form some sort of power relation with one another, the twists and mysteries, etc.
What I really disliked: the amount of cast members(important and lesser members, those who've appeared and those who haven't) which will likely mean limited characterisation or even recycled characters and dragged-out tournament fights unless the manga creators can get it right(tough if you're trying to go for a mostly fighting manga unless you veer from that direction or can handle it). And too much random stuff in every odd chapter instead of building on the plot, character and action layers bit by bit and that the rapid pacing in the earlier chapters is starting to slow a darn lot.
So, I'll probably pick up this series again in a while's time to see if it crash-landed or headed for a round of smooth sailing. And it's worth checking out just for the fun of it.
