The game mechanics is really good. Though I'd like to suggest, the game have animated gifs of characters like the one the Alice event at the left side of the character, why not make it an option to see them while viewing the character story or even while viewing the Hero's list.
Also, I'd be great if you can update the novel and also improve the interface.
I think this game would be much better if you can tie up the stories and make the world building much more immersive.
Also, maybe it's time to release it as a separate game program/software as well.
