Alright, thanks for the help then; I don't know if i will really get cthulhu or just Ares/Titania or even someone totally different yet since I'm only playing for fun and want to get my favorite characters but thanks anyways.

So which legendary soul is the most useful for me right now? i actually wanted to get mordred next cuz i like her but i actually wanna get the best one to round out my team for now.
And what about ryu-oh? is she any good?
