Corporate slave Arihito Atobe's death in a freak bus accident marks the beginning of his new life as a kind of adventurer called a Seeker. Reborn into a fantasy world, he settles into a previously unknown job class called "rearguard," capable of providing his (all-female) party with critical attack, defense, and recovery support. And it comes with an added bonus: Simply being at the back of the party line increases his companions' fondness for him! Freed from the shackles of corporate life, Arihito is eager to start fresh as a newly minted Seeker!

Arihito has obtained another Hidden God armament and foiled a plot by a member of the White Night Brigade that put him and his friends in danger. His valiant actions catch the attention of the Guild Saviors, who request his party’s assistance in suppressing a stampede in District Five. Then, a potential opportunity arises to rescue Elitia’s missing friend…How will Arihito and his group realize Elitia’s most deeply held wish, even when the odds aren’t in their favor?

Arihito’s rearguard skills have safely bumped him and his party up to District Seven faster than any other Seekers in history. Just when their upward trajectory seems unstoppable, new obstacles stand in their way: the district’s top-ranked alliance, Beyond Liberty, and its monopoly over the labyrinth’s prime territory! The best shot Arihito’s group has at progressing any farther involves teaming up with an all-female party—but are two parties better than one? And with the best hunting grounds out of reach, can they earn enough points to make it to the next district?

After their many triumphs against powerful Named Monsters, it’s time for Arihito and his party to take a much-needed break! Their first post-reincarnation vacation brings them to a health resort managed by the Guild, providing the perfect opportunity for the group to get to know one another even better. Rest and relaxation may not come easy for Arihito and his friends, though, because a familiar face from the White Night Brigade has an eye on Arihito’s infamous rearguard skills...!

Once, the scariest thing to Arihito Atobe was his workaholic boss, Kyouka Igarashi. Now, this ex-corporate slave faces a world where monster-filled labyrinths are the norm and teamwork is key to survival. While others are eager to charge headlong into battle, Arihito chooses to become a "rearguard": a class dedicated to helping allies from the back lines. The rearguard gig should be his ticket to avoid repeating his old life, but this opportunity may just shed new light on what it means to support one's partners and work together!

Arihito and his party faced off against the Shining Simian Lord in District Five and successfully rescued Elitia, but the curse this horrible beast inflicted on Theresia is destroying her bit by bit. If nothing is done, she’ll soon become another one of the Simian Lord’s mindless underlings. In order to save his companion from this dreadful fate, Arihito must find a way to lift the curse on her and defeat the Simian Lord... But can Theresia hang on that long...?

Arihito and his makeshift party have somehow emerged victorious against the Juggernaut. Having heard about the miracles of the cathedral in District Four, they feel a renewed determination to make Theresia human again, but many labyrinths stand between them and their goal. Though his allies have doubled in number, will Arihito’s rearguard abilities be enough to protect them?

A DEMON IN THE DUNES With their rigorous training session behind them, Satou’s party is finally prepared to take on the tougher enemies of the Celivera Labyrinth. Never ones to shy away from a side quest or two, they also find a hot spring and open a Japanese-style inn on the spot. Areamasters and floormasters beware! This group is refreshed and ready for battle! Unfortunately, the opponent who finds them turns out to be someone nobody saw coming…

A SIGHT FOR SORE EYES! ​Having toppled another powerful foe, Satou’s group heads back to Labyrinth City to celebrate their achievements. Upon returning, they’re greeted by two familiar faces—Zena and Karina have come to Celivera! Plans are made to give them a warm welcome, but those get derailed when Zena runs into trouble. Her labyrinth dive takes a turn for the worse when a monster kidnaps her, so Satou rushes to her rescue. Inevitably, he finds much more than he bargained for! It seems a Hero’s work is never done…

Showdown in Castle Town! Having successfully averted the airship attack, Satou and company arrive safely in the royal capital. There, they are reunited with Nana’s “sisters”—Numbers 1 through 8—and give them the gift of a lifetime. But as is tradition with every trip to the capital, Satou must rub elbows with the aristocracy before he can enjoy his sightseeing. He even receives a surprise visit or two, including a summons from Sir Juleburg of the Eight Swordsman of Shiga! Because no leisurely trip would be complete without a friendly duel…
