Out Today: DCU’s Son of Batman and Super Groovy Cartoon Movie
Batman learns that he has a violent, unruly pre-teen son with Talia al Ghul named Damian Wayne who has secretly been raised by Ra’s al Ghul and the League of Assassins. When Ra’s al Ghul apparently dies after a battle with his former right-hand man Deathstroke, Batman must work to stop his long-lost son from taking revenge and guide him to a righteous path, in order for the pair to truly acknowledge each other as family.
I hope it's not Crunchyroll; if they really cared about the franchise much, Volume 10 would have already been announced a long time ago.
