This is the isekai that actually respects the support class instead of making you wait for the healer to matter. Arihito Atobe dies an overworked salaryman and wakes up as a Rearguard, the one build that can tank, heal, and buff at once, and the show treats that utility as the whole appeal instead of a gimmick before he unlocks a flashier class. No power creep theatrics here, it's dungeon by dungeon, rank by rank, with the camera more interested in positioning and party synergy than screen-shaking spectacle. Dragging his former boss into the Labyrinth Country alongside a demi-human mercenary turns the party dynamic into the real engine of the story, loyalty and competence over chosen-one nonsense. If you've ever wanted an isekai that plays like a methodical tactics sim instead of a power fantasy highlight reel, this is built for you.

Arihito never expected his mundane office job to end in a fatal accident. Instead of oblivion, he wakes in the Labyrinth Country, where newcomers become adventurers called Seekers and venture into dangerous dungeons. He discovers he's been assigned an unprecedented job class: the rearguard. Rather than fighting on the frontlines, Arihito supports his party from the back, boosting their attacks, bolstering their defenses, and healing their wounds. The catch is unusual. Simply standing behind his all-female party members causes them to grow fond of him, a perk that seems almost too good to be true for someone escaping years of corporate drudgery. Free of his old working life, Arihito throws himself into life as a Seeker, joined by a demi-human mercenary and his former boss. Yet not even the Seekers Guild can work out what his class truly is, and learning its hidden potential may be his hardest task.
