Casshern Sins (2008)

S1E1 At the End of the World

The world Casshern awakens to is nothing but a decaying, acid-scarred ruin. Adrift in a future that feels utterly alien, he has no bearings, no allies—only the relentless pursuit of enemies who want him dead. Every step is a fight for survival, a desperate gamble to outrun the shadow of destruction closing in around him.
