Mostly recommended for Suzaku fans. This series has a main character who shares many similarities with Kururugi Suzaku: (Spoilers) 1. has committed a great wrong in his past, 2. goes beserk and becomes almost undefeatable when attacked, 3. has a 'curse' upon him such that he can't die. 4. Also spin kicks and cries abundantly. Secondary (female) character of the series also bears some similarities to Kallen.
In sum, if you enjoyed watching Suzaku angsting/brooding and trying to find atonement, you'll probably enjoy Casshern Sins.
