Lets use this thread to discuss all the vampires past and present, and discuss what we think their motives are, seeing as we know so very little about where they come from and why they side with the aliens.
A few facts (Please add to the list)
1) they first appeared after the Dino mission.
2) They hate the Gantz team and side with the aliens.
3) Their hang out is a club were they conduct fights, lure in humans to suck their blood, and discuss business.
4) they were successful in killing Kei and Izumi.
5) at this point in the story 2 vamps. "Host samurai" and "Killbill" are members of the gantz team.
6) Akira Korono was also a vampire, although it is still unknown how he became one.
7) Vampires have tiny nano machines in their blood. If a human gets these into his blood by accident in the case of Akira, or on purpose in like likely case of Killbill they become vamps also.
