Typical company employee Tanaka Daichi (38-years-old, single) loves games and plays a new type of VRMMO called "One More Free Life Online" under the username "Earth."

Be it wasting time crafting potions, cooking up pointlessly tasty food, or hunting monsters with some absurd weapon he crafted, he simply enjoys playing the game.
