It turns out that the travelers Ryoma saved were the local duke and his family. Impressed by Ryoma's various skills and enamored by his personality, they offer to take Ryoma along on their journey.

Ryoma arrives at Miya's house, overflowing with trash from a nearby dump. Ryoma and his slimes show a remarkable ability to clean, a skill that, as it turns out, the town of Gimul desperately needs.

Eliaria and Ryoma practice magic and combat in Gimul. They practice fighting against the weak but numerous monsters now infesting the abandoned mine shafts.

Ryoma decides to strike out on his own as an adventurer and business owner. He discusses his plans with the ducal family, and works with Serge the merchant to put his business plans in motion.

The laundry business is ready to open. Ryoma hires new employees to help get his business started, and throws a party to express his thanks to the friends who have supported him thus far.

The laundry business explodes in popularity, so Ryoma rushes out on day two to hire more help. He meets Fei and Li Ling, foreigners with a hidden past.

With the business going more smoothly than Ryoma ever imagined, Ryoma is able to go back to studying his slimes and adventuring. He discovers several new types of slimes.
