In a company where violence, gunfire, zombification, and electric shocks are everyday occurrences, a fresh-faced new employee known only as Newgrad-chan steps into an office that has no straight man to rein in the chaos. The story follows her as she navigates a workplace populated by colleagues who treat absurdity as normal. Her senior, Yuu-senpai, is a taciturn fighter who communicates directly through telepathy and can knock out anyone with a single blow. The president is a seemingly friendly old man with a surprising amount of physical strength, while the department head, Chief Tsukumi, is a rabbit-like figure whose breath reeks like a miasma. The president's spoiled daughter, Maria, is a wealthy ojou-sama who casually spends large sums on friends. Other recurring characters include a grim reaper-like doctor, a cleaning lady who doubles as a zombie, and a variety of equally unhinged supporting staff.

The narrative unfolds in a fast-paced four-panel gag format, with each episode delivering a self-contained absurdist sketch. There is no overarching plot; instead, the humor stems from the complete lack of normalcy. Job interviews become physical brawls, orientation involves learning to withstand body blows, business card exchanges turn into battles of smashing cards into the ground, and customer service training covers how to answer the phone even when a murderer appears. The world of Kyatapiland is one where basic office tasks escalate into cartoonish violence, and every character contributes to the mayhem with a straight face. Newgrad-chan herself is resourceful and ambitious, often trying to one-up her colleagues in equally ridiculous ways, such as destroying office equipment with her bare hands or replicating documents by perfect hand-drawn copies. The series revels in its nonsensical logic, drawing readers into a workplace where the only rule is that there are no rules.
