Holy mother of amazing character designs x3 It's hard to even pick a favourite, but if I were forced to, I think I'd have to go with Azza, but really they're all just gorgeous :3 Not just the character designs though, all the art is a treat for the eyes!
The story is very heartfelt and an interesting concept with a colourful cast of characters. It's really neat that you made it as a standalone demo but that it's also part of a larger world/story. I love stuff like that :3 I wish you the best of luck with future development
