Ryouma may look like a preteen child, but he’s actually the reincarnation of an adult salaryman who died from overwork at his stressful, exploitative job. He spends the first few years of his new life taming slimes and even discovering new types that eat dirt and grime, until he finds himself in the good graces of a local duke’s family and they introduce him to the rest of the world. Determined to make his own way without relying on the family’s financial support, Ryouma ends up opening a laundry service that uses his slimes to clean extremely tough stains most people would just give up on.

What’s particularly sweet about Ryouma is that he puts serious effort into making sure his employees are treated well (unlike, say, Yuna from Fall 2020’s Kuma Kuma Kuma Bear, who doesn’t see anything wrong with making dozens of children work day in and day out). He builds dormitories for his workers, hires them a cook, factors in paid holidays, frequently checks in with them to make sure they’re happy, and much more. The laundry service may only have a small impact by itself, but Ryouma’s introduction of fair employment practices is sure to make lasting waves in this world’s culture.

Genzou, on the other hand, doesn’t have much of a plan for his new ventures in isekai land, but he’s got a good heart and a lot of people to help him. Formerly a professional wrestler called Animal Mask, Genzou is called to this world to defeat a plague of monsters... but upon learning that he’s being asked to hurt what are basically animals, he suplexes the princess who summoned him and runs off to start a pet shop so people can understand how adorable these creatures really are. In the process, he also introduces wrestling to the flabbergasted public and they discover a deep love for the spectacle and athleticism of it all.

Hilariously, the pet shop and pro wrestling projects somehow manage to solve the underlying monster problem, since the monsters start to respect Genzou and the draconic princess causing most of the issues accepts defeat in the ring (for now). Genzou does have a few bad habits, like spending what little money he has adopting new pets and insisting on cuddling any creature he comes across, but his contributions to the town’s welfare are uniformly positive.
