This Comic's Cast:

If you take every game release where she has been a playable character, that makes... three: Rondo of Blood, Symphony of the Night, and Judgment. Symphony has multiple iterations with different playable versions of Maria, and Rondo had two. So, she's been playable like... six times and presumably fought some kind of Dracula every time.

Oh, and she was unlockable (along with Richter) in Portrait, but that's not continuity. And, if we're going to count that, there's also Harmony of Despair.

So, what... eight times, maybe?
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
