Slime's up for one recently deceased middle-aged businessman! When the gods reincarnate him in another world as a boy with magical powers, he discovers that magically-tamed slime are an untapped natural resource!

In his past life on Earth, Ryoma worked himself to the bone as an employee of an exploitative company. Now, in Seilfall, the former office drone decides to start a business of his own?!
