I'm on the bandwagon with Pradeepsixer. The Black getsuga tensho is part of his hollow half. As he was able to use that form of getsuga tensho you would think he still has the hollow powers. However, you never see him interact or deal with his internal self so is it still there? But Ginjo and Ichigo do have that hollow/shinigami connection, though Ginjo's mom was attacked by a hollow before he was born so I don't know how connected.
