This series started out with quite of bit of promise. The world in which this takes place in seems to be pretty interesting- "lost preciouses" floating around the world which have untold powers, a "society" of people, breakers, that have the ability to use these lost preciouses or would like to research them. Anways, on to the review...
This is a very disappointing story. The premise was very strong, and the first arc was somewhat decent, but all they do is build a few new characters in the following arc and the final arc is... horrible. They manage to survive through a plot device, after the main character does something stupid brought about by another plot device. This story is just not alll the great.
This series employs a slightly unusual or non-mainstream art-style, but most of the action is well done and the character designs are fairly unique and attractive. Nothing that would be a game changer, if you will, but it was well done.
Some of the characters in this series are fairly good... but too many lack any depth, are too cliched, or just not needed. Ai, despite having a bit of depth, could have been dropped from the story and everything would have been fine. Margura was an ok character, but lacked a reasonable amount of depth. Ryuuji's parents, these bad-ass breakers, barely even make an appearance and then just disappear. Eriko just hangs around for no real reason and is given basically no depth.
Well, this series was, for lack of a better word, an utter and complete disappointment. And that's all I really have to say for it.
