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 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?

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!

Having formed a party and acquired companions to explore the world with, Arihito is finally settling in to his new normal as a Seeker in Labyrinth Country. But when a girl goes missing, he's soon plunged back deeper into the dungeon than he may be prepared to handle...

Having formed a party and found companions he can explore the world with, Arihito is finally settling into his new normal as a Seeker in the Labyrinth Country. But when a girl goes missing, he's soon plunged deeper into the dungeon than his party is prepared to handle...Despite joining up with "Death Sword" Elitia and Shrine Maiden Suzuna, Arihito and his team may be in way over their heads!

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?

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?

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...!

Down in the uncharted depths of the Field of Dawn, the gang faces off against the "Eagle-Headed Warrior" Named Monster protecting his domain. Arihito manages to save his friends from the monster's crushing power, but takes a fatal blow since his defensive barrier doesn't work on himself...

Here Comes Trouble...One of Lydia's former soldiers, Sylphy Marheaven, is starting to suspect that this "Ard" character might just be the reincarnated form of the Demon Lord. So when she discovers his whereabouts, she packs her bags and transfers into his academy, dead set on finding out his true identity. And as if Ard's hands aren't full enough, he's got the upcoming school festival to think about, which should be fun...besides Sylphy surveilling him around the clock and the threatening letter he's just received. But, of course, isn't everything a breeze when you're the greatest Demon Lord?
