I read renaissance eve before this one and Reiji is there and he said he's a lot older than he looks. So, I think this was setup way before renaissance eve, and Renji is not dead yet. He survives and got picked by the professor munakata and then team up with F and Shizuma.
The type v and t blood later was collected and given to Julius...
Plus, given how they look, maybe Mikoto and Chiaki are related somehow. And since the T type girl "Enforcer" has her power given by the surgery, maybe the bone marrow comes from this girl. Who knows.
