That effect is also in Dawn of Sorrow; Alucard doesn't have a reflection when you run past mirrors.
From Van Helsing, PS2

I implore everyone here to
buy one of these:

I have this on my keychain and ever since I bought it, i've been getting compliments & inquiries left & right from everyone I know and don't know! Even some girls ask me about it, "why is that cross on your keys so sharp??" so it's also a chick magnet

Little did anyone know that it's a relic from the CASTLEVANIA series lol. It's made of metal so it won't break off. It's identical to the last detail & very sharp, i stabbed my coworker with it & it pierced his skin with no remorse. I think it's cool to have & should've been included with the collector's edition. only downside, KEEP OUT OF REACH FROM SMALL CHILDREN!
