Taichi Tanaka, a 38-year-old office worker, is an avid gamer and lives a solitary lifestyle, whether in the office or at home. In his spare time, he devotes himself to his latest addition, "One More Free Life Online", a brand new VRMMO. But Taichi is not your average gamer, rushing from adventure to adventure, tirelessly fighting monsters. On the contrary, in the virtual world of "One More Free Life Online", Taichi reveals his genius as a masterful cook and skilled potions brewer.
However, his culinary and alchemical skills are not his only unusual talents. To gather the ingredients for his cooking and brewing skills, he takes on monstrous creatures, using only homemade, bizarre-looking weapons. Because for Taichi, only one thing counts in the end: having maximum fun in the game.
