Something interesting that I found out today. Reading a book for history class today, they mentioned "tsutsugamushibyo" -- a typhus-type disease from a chigger bug called a tsutsuga bug.
Hence --
Tsutsugami Gai -- chigger bug god?
Aka biting at the occupying GHQ forces.
And of course I mentioned earlier Ouma Shu could be related to genetics. I remember in Vandread they said the one parent in the all-female society was called the Ouma. Which would fit with the Void Genome stuff, but I'm not sure about this connection.
