Well, Ikeda is certainly being forced to think the Shinso blood thing through on this - we won't accept some half-assed explanation!
In regards to Akasha, I really want to know where SHE came from. She's obviously from Europe so Moka's English could be of the British type - which for some reason, I'd REALLY want to hear Moka with a deep voice tinged with a British accent... 0.o Something about that... :nosebleed:
Anyway...While Akasha could indeed sense the Shinso blood, I don't know if it would Synchronize just from that... Well, like you said, we don't know about the blood synchronization to speak of it definitely.
And the Shinso blood really is just a higher density blood in terms of a vampire's power. Pretty much high octane jet fuel instead of regular unleaded....
I wonder if anyone altered my lil posting on it on the R+V Wiki...
