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!

Undead adventurer Rentt Faina manages to survive the poisonous Tarasque Swamp and retrieve the Dragon Blood Blossom for the orphan Alize. Just as he's about to return, a mysterious stranger approaches him. The man offers him a job on behalf of his mistress, the Latuule matriarch. Rentt accepts the request, and at the behest of Sheila and the adventurer's guild, he agrees to meet with the elusive head of the Latuule family. However, there's more to this family than meets the eye. Will meeting one of the oldest and most influential families in Maalt go according to plan, or will Rentt get more than he bargained for?

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!

Rentt Faina, the undead adventurer, agrees to take on a request from the Latuules, a highly influential yet mysterious family in Maalt. There's just one complication-in order to actually meet with them, he has to find his way through a giant hedge maze! At the end of the maze, Rentt finds the Latuule matriarch, a young girl named Laura Latuule. Laura explains the request, and as thanks for him accepting it, she shows Rentt her family's prized magic item collection. Rentt is fascinated by the sheer number and variety of items...but when he accidentally activates a magic golem, it's time for battle!

When Rentt Faina crosses paths with Nive Maris, he finds himself victim to a rain of Holy Fire! But rather than prove he's a vampire, it disproves it! Lorraine believes Rentt's divinity may have protected against the Holy Fire, and together they decide to make for Hathara, where Rentt obtained his divinity. Before Rentt and Lorraine can depart Maalt, they first need to create wands and equipment for their disciple, Alize. To avoid trouble with others like Nive, Rentt has to negotiate with the Guildmaster, Wolf Hermann, to have his double registration officially approved. But as Wolf oversees countless ruffians, this'll be no easy task! An undead with a dream, eternally striving for the rank of Mithril-class!

After his evolution to a thrall, Rentt Faina sets out to explore an unmapped part of the Water Moon Dungeon. He finds a secret chamber, guarded by a mysterious woman. She offers him a treasure called the Map of Akasha as long as he keeps his silence about the secret chamber. Rentt agrees, but before he can find out more about her, she teleports him out of the dungeon. Rather than fret and worry about this odd meeting, Rentt continues on his path to becoming a Mithril-class adventurer. His next hurdle? The Bronze-class Ascension Exam! His adventure as an undead is only just beginning!

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!
