This was a fantastic Anime that while at points was a bit slow, overcame this with fantastic action scenes, an amazing plot and a soundtrack to go along with it all.

I would rate this series as one of those that is worth purchasing based on season 1 alone.

In a sense its similar to The entire venture brings the viewer along for the ride and is only made better by the fact the writing and animation are made to suit. I would argue that if anything were to be improved upon it would be the slow pace of the plot at certain times, taking more time than necessary to get from point A to point B.

All in all at the end of the day if you enjoy a series with an engaging plot, an entertaining cast of characters and a superb amount of polish, check this serious out.
