You meet Villager and he tells you that there is a god in the lake who tells him that his wish will be granted if he prays constantly. Just as he wishes, he meets you again. But it turns out, that he is not the only one who prays for that in the lake. Slime, Maou, and Dark Knight do so too. For you to return to your world, you have to do one quest with them. The adventure with this party then starts!
You woke up in a familiar world with four equally familiar faces staring back at you. Why, you are inside the game you used to play entitled Unlimited Quest! o/ These guys are the characters from the game and they are holding grudges against you. Thanks to you they have become warped!
