My guess is that they willingly become his servants and when they do, they lose their connection to their home world and get connected to Yamigedo. All Ban is doing is restoring the connection. One can also imagine that said HD would eventually regret their actions and not want to go back. The point is still that they do this of their own free will, mostly.
