Hakkenden: Tóhó hakken ibun - Season 2

Strangely, even though they aren't brothers, Shino and Sosuke bear identical birthmarks. When a fire destroys their village, leaving the two of them and Hamaji as the only survivors, they are forced out into the world. There they meet Genpachi and Kobungo, two soldiers who also have the same birthmark and whose confrontations with demons have left them irrevocably changed. Now however, they are on the run as the Imperial Church tries to capture Shino and take his mysterious powers for themselves. The unlikely quartet's only hope is to discover the secret behind their birthmarks, which will lead them to eight magical gems and their owners. (Sentai Filmworks)
