A group of orphans are adopted by the government and trained as deadly assassins. As one can imagine, this suspect-yet-effective program starts generating some serious moral crossroads for all those involved.
The title is doing itself any favors. However, it does manage to takes itself very seriously without taking itself too seriously, which is a rare thing to find when it comes to anime and it works damn well to boot. Surprisingly good stuff that’s digs deeper into its characters than I was expecting it to. The action ain’t too shabby either.
