Shame we cannot see the rest of the series. Not in manga form at least. The fact that it was removed from sell, and that the artist didn't know until it happened, implies that it's a licensing issue. Makes sense, I believe there were other manga's and related to the series but were published by other groups. If I am right, there is a decent change it will be resolved but it will take time for the corporate lawyers to sort it out. A year minimum. And that is assuming they want to spend the money to fix it.
