I'm starting to like Rider's sisters more and more.

considering that Rider is the youngest one of the Gorgons, yeah

she's the youngest, but looks the most mature among all three ?
by the way, how could we recognize which one is Stheno and which one is Euryale ? ^^;

Aren't they suppose to be ugly?

If they're supposed to be ugly, then the artists fail pretty hard at making ugly chicks.

no one really wants to see ugly female characters anyways...i guess you can call it a successful failure. that wins hard.

Remember, that Medusa was made ugly, because she was more beautiful than Aphrodite, and the goddess was jealous.
