This is the fastest way to describe the plot of this awesomely done anime series. The series is crafted in a way to make your heart shutter. Visuals and animation is topnotch(well madhouse), Music is breathtaking and binds with the atmosphere very nice, Plot is very well done and will keep you guessing...but the strongest part of all is the character development. Its not easy to talk about character backgrounds because Casshern meets a lot of interesting characters on his journey but even if Casshern interacts with some characters briefly, it leaves you satisfied.
This is not your average anime series. Casshern Sins is a drama unlike anything else you've ever seen. And its granted that when you finish the series you will remember it for a long time. If you are looking for a typical sci fi anime look elsewhere. Casshern Sins is all about finding one's self and the road to redemption....
