"Ichi Nichi Shite Narazu" is a comedic anime series that revolves around the daily lives of a group of eccentric characters working at a small, struggling publishing company. The company, which produces adult magazines, is perpetually on the brink of financial collapse, and its employees navigate a series of absurd and chaotic situations in their attempts to keep the business afloat. The narrative is episodic, with each episode presenting a new set of challenges, often stemming from the characters' poor decision-making, interpersonal conflicts, or external pressures.

The protagonist, Ichirou Suzuki, is a naive and somewhat clueless young man who joins the company as a new employee. His lack of experience and awkward demeanor frequently land him in trouble, but his earnestness occasionally shines through, endearing him to his coworkers. The company's president, a brash and unpredictable figure, often devises outlandish schemes to boost sales or cut costs, leading to further complications. Other key characters include the cynical and sharp-tongued editor, the perpetually overworked office manager, and a quirky artist whose eccentricities add to the workplace chaos.

The humor in the series derives from the exaggerated personalities of the characters and the ridiculous scenarios they find themselves in. Misunderstandings, slapstick comedy, and satirical takes on workplace culture are recurring elements. Despite the comedic tone, the series occasionally touches on themes of perseverance, camaraderie, and the struggles of working in a declining industry. The interactions between the characters drive much of the narrative, with their contrasting personalities creating both conflict and moments of unexpected solidarity.

The plot does not follow a linear progression but instead focuses on self-contained episodes that highlight the absurdity of the characters' lives. Each episode builds on the established dynamics of the group, with recurring jokes and running gags tying the series together. The setting, primarily confined to the office and its immediate surroundings, reinforces the sense of a small, insular world where even minor events can spiral into major disruptions. The series balances its comedic elements with a subtle undercurrent of realism, portraying the challenges of working in a niche industry with limited resources and uncertain prospects.
