Well, Reika has always been all over Kurono since the first mission together. Tomb liked the messed up Kurono, and Tae is the person who changed Kurono. The rest of the girls, and there have been a ton of them, have nothing to do with Kurono.
LMFAO bro Reika is deranged, I need me a big oppai ride or die like her fr fr. she gotta point, "I forced him into this, might as well face the consequences together"
