Since the anime was released and promptly canceled for release in the US, is there any problems with copyright associated with this series? Is there someone else who holds the copyright for the manga separately from the anime? If not I see no reason that should prevent a group from translating this.
Also due to the release of the anime in the US many people have gotten into this series, and due to the cancellation before the series conclusion; There will be many people that will come to read the manga to see where the story progresses, that is if someone starts translating this. Whatever group picks this series up will defiantly gain a good amount of traffic once they pass where the anime was canceled.
