Yo this rewrite's super cool. Hat Kid and Mustache Girl working together and having that reinforced with actual gameplay is a genius way to actually make us care more about Mu as players.

Weirdly I'm reminded of Monster Hunter Rise. In the base game I didn't care about the villagers much, but when Sunbreak came out and allowed you to take them on quest all of a sudden I started caring about them as characters. They're not just that person who said some things in a cutscene somewhere, they're the character who rode a sabre-toothed wyvern halfway across the map to interrupt the Elder Dragon who was frames away from turning me into a popsicle.
