No worries on the blood magic, the other game treats it as highly illegal, and the game here treats it as highly dangerous. Having a vampire gf would be super interesting, given MC's already got succubus gfs, an angel gf, a doggo gf, and a slime gf... but curious if having a vampire gf would clash with someone (say, a certain daughter of Gaea)
Ashley, I'm aware hides her insecurity behind flirting and teasing. When you get her to serious, she unloads a lot. Sarah is more open about it, but both are struggling with a lot of issues.
You didn't mention Batman was making an appearance in Divine Dawn! lol
