You don't have to answer if you don't want as I know you're amazingly good at cliffhangers, but in the story the characters warn the MC not to have sex with the vampires.... Will that ever happen? And to clarify I mean sex with the vampires lol.
Hehe. It's basically already answered in the game, so I don't mind answering this: There is at least a drug that would allow MC to have sex with vampires, yes. Uraha mentioned it before. Now MC only has to get it from somewhere.
