Ryoma continues to enjoy his extended time in the fishing villages of Fatoma territory, away from his home base in Gimul. As he streamlines his morning hunts of mad salamanders to protect the fishermen at work, Ryoma receives two more special requests from Count Porco, lord of Fatoma, where his culinary ingenuity shines! Can Ryoma accomplish Porco's quests with the help of his evolved slimes, modern knowledge, and experience in this fantasy world? While his slow living comes to fruition, a shocking truth about Ryoma's previous life is revealed...!

Ever since he left the forest, a boy from another world named Ryoma had been cared for by the duke's family. Rather than take advantage of their generosity, however, he's determined to live independently. Seeking to earn a stable income, he decides that alongside his adventuring job, he'll use his cleaner slimes to open a brand new laundromat! After he sets up his store by himself and hires some excellent employees, the laundromat opens to praise that far surpasses Ryoma's expectations. As business gets busier and more exciting, he also gets ahold of some new followers in the third installment of this daily life fantasy!

With the help of the Jamils and volunteers throughout the city, Ryoma’s ventures in city management and defense have come to full fruition—just in time to combat the sinister forces plotting to bring down Gimul. As fires and violent attacks break out across the city, Ryoma jumps into action, but he soon discovers that his enemies are after him personally... Now Ryoma must fight to protect the city of Gimul, along with all his friends!

In this isekai for dog lovers, an office worker is transported to another world...with his loyal canine companion! Takumi often works overtime and gets home after dark. At least his beloved Maltese puppy, Leo, is always happy to greet him when he returns home. One day, Takumi wakes up in an unfamiliar forest...and right in front of an enormous wolf! Wait, could this gigantic canine actually be his once-little Leo?! With the help of a mysterious new magic power, Takumi will do his best to make a laid back, easy life for himself and his furry best friend!

Thanks to the windfall from his first solo adventure, Ryoma's able to open a second slime laundromat. Once back home in Gimul, Eliaria sends him a letter to inform him of the city's upcoming Founding Festival. Follow along with Ryoma, as he sets out to open a stall at the festival to sell foreign food and unique drinks! But will everything go to plan, or will trouble find Ryoma once more?

Concerned by Gimul's changing social climate, Ryoma resolves to revive the city and eliminate the mastermind behind the city's decline, calling on the full strength of his connections to set in motion a plan that will revolutionize public policy and make the streets of Gimul safe! Meanwhile, the nine gods have a key detail about slime magic to share with Ryoma...

Now that Ryoma has parted ways with the duke's family, it's time for him to begin a new life on his own in the abandoned mine he manages. Assorted issues crop up at his laundromat, but, as he solves them, he installs more security equipment in the store and becomes closer with his employees. When it's suggested that he start training new staff so he can open a second laundromat in another location, Ryoma seeks out the ideal spot for his new store by going on a solo adventure for the first time! Ryoma's connections with the kind people around him further expand his world in the fourth installment of this daily life fantasy!

Ryoma, the boy from another world, takes the opportunity to revisit the Jamil estate, where his fellow merchants Serge and Pioro and a friend's unexpected marriage are all converging. Ryoma's happy to help the young lovebirds-provided he can tear himself away from developing new uses for his slimes and expanding his business! There's more familiar faces and laid-back scenes to come as well, of course, and a stalwart (if dubiously attained...) new ally too!
