Problem
There isn't an anime for Mystic Messenger.

Solution
Cheritz should make an anime for Mystic Messenger. The game already has a huge fan base and it would only grow if there were an anime. It is obvious that majority of the fanbase would love an anime since most create fanart and videos for the game. Cheritz would benefit greatly from this as it would also expand the fanbase.

Personal story
As a fan of the game myself, I can say for certain that I would love an anime for this game.
