When I saw the archer girl, I couldn't help but think "Sonia Belmont!!!" Of course she's using a bow, but if Alucard can use a whip in LoS, no reason Sonia couldn't use a bow. Recast her as a member of the brotherhood (sisterhood?) of light? Haha.
Another thought was that this was a Japanese take on a western take on a Japanese game that was a take on a mostly Western lore.
And no, Castlevania is not only a pachislot series now. It's a normal slot game series too haha.
