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?

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?

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!
