Oddly, I love the series/manga... Yet Eris is ironically my least favorite girl, namely because of her attitude and behavior overall -laughs- would love to put her in her damn place at times... My favorite "Eris" is from Cat Planet Cuties. But I've noticed that not a lot give love to Ghislaine and several others either.
Guess we (the players) shall see what you have in store, good luck with the animation, will be nice when it's more fluid dynamic and perhaps some sort of audio to give it more immersion.
