By the Grace of the Gods

神達に拾われた男

Forty-something Japanese office worker Ryoma Takebayashi dies in his sleep and is brought to a sword-and-magic world by three gods who let him start over as an eight-year-old boy. He spends three quiet years alone in a forest taming hundreds of slimes and discovering new varieties that can clean, scavenge, fight and craft on his behalf. When Duke Reinhart Jamil and his family stumble across his camp, his slime-keeping skills draw him into the city of Gimul and the wider business of the kingdom's adventurer and merchant guilds.
