Haito and Lina, a newlywed couple, purchase the full-dive VR game "Free Frontier Online". Their reason for playing is to be able to pet and fluff as many monsters as they wish! The two, who are unable to keep pets due to animal allergies, come up with the idea that they can interact with fluffy animals as much as they want in the game, so they start the game as tamers. They thought they started with the purpose of relaxing with the monsters, but before they knew it, they ended up obtaining a familiar stronger than the monsters...!? They will tame, they will battle and they will flirt!
