True that the characters are based on characters from classic stories (not just fairy tales), but they're not going to follow the story of the character they're based on. It's just a fun little theme they're doing.

They have acknowledged that Roman looks kinda like Alex Delarge. In the DVD/Bluray directors commentary, one of them even says "Shoutout to Clockwork Orange!"

For Penny, I'm assuming you're talking about her weapon. Monty used that kind of weapon for Namine in Dead Fantasy. Apparently, a character in League of Legends uses that kind of weapon too.
