The second Utawarerumono OVA is already out.
It's hardly relevant, though pretty funny. It's a new story, which has no relation with any scenario in the PC game. It takes the main characters from the PS2 only scenario, though it didn't seemed to me the OVA plot had any relation with the PS2 scenario plot (although since I didn't understand the later, it could be that the main points were the same).
And now only the third OVA remains. What will it be about? Will it expand this OVA characters and use the PS2 scenario? Something completely new? I'd like to see a prequel, about how Benawi and Kurou got to work for the former emperor.
Also, the OVA picture drama is out since some time ago. This was also a completely new scenario, about how Urtoriy and Karura met. I wonder how canon it is?
