In a certain RPG world that had just reached its ending... Marius, the sage and a member of the party that saved the world, was investigating something at the request of the hero, Lydia. It was the reputation of this game, based on feedback from users who had played it all the way to the ending. However, Marius's investigation revealed... the game's reputation was "GARBAGE"!! A worthless pile of crap with no redeeming qualities!! Learning that the scenario, in particular, was poorly received, Lydia and the others were thrown into an uproar. In an effort to overturn this reputation, they decided to use their last resort: "Edit Mode." Using it, the characters could ignore the scenario, move according to their own will, and create the story themselves. However, to avoid arousing the users' suspicion, they had to improvise everything seamlessly and without contradiction!!
