A 30 year-old construction foreman and company worker, Satou Tarou dies from an unexpected accident. However, he receives a cheat-like ability from a god-like existence which allows him to cast healing magic and the knowledge to produce potions.

Using his newfound powers within this new world, Tarou accumulates a surplus of wealth and changes his name to Tauro. Setting his sights on the pleasure quarters of this parallel universe, perhaps the beginning of a new legend is on the rise….
