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!

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 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?

Thanks to a severe wound, Arihito is all too aware that his rearguard powers have one major flaw: He can’t use them for personal protection! Now it’s up to Kyouka and the rest of the party to support him, but can they overcome the Field of Dawn’s mighty gatekeeper, the Giant Eagle- Headed Warrior? Victory would mean discovering powerful secrets about the world—including the reason they were all brought to the Labyrinth Country in the first place!

Having awakened a Hidden God at the heart of the Labyrinth Country, Arihito's party has shot to the top of District Eight's rankings, overtaking the previous #1 party, Polaris. Now the friendly rivals aim to take the exam to rise to District Seven together…and not even a stampede is going to stop them! Can Arihito's party pass their exam and protect civilians in danger, all while holding their own against waves of escaped monsters? Perhaps an unexpected ally will help turn the tide…

Just as Arihito and his party are in the midst of quelling a stampede, a giant monster capable of overpowering his support and defense skills appears. With civilians to protect and a formidable foe to defeat, Arihito fears his luck has finally run out. Yet when all hope seems lost, one Hidden God’s powers will manifest and flip the battle on its head...
