Arasa OL Haman-sama reimagines the formidable antagonist from the Universal Century Gundam series, Haman Karn, as a thirty-year-old office worker navigating the mundane challenges of corporate life. The story is a slice-of-life comedy set within a Gundam-inspired office environment, where Haman serves as a high-level executive at the Neo Zeon apparel company. The premise contrasts her original characterization as a cold, ruthless regent with the everyday misadventures of a modern working professional, drawing on characters and dynamics from Mobile Suit Zeta Gundam and Mobile Suit Gundam ZZ. The narrative follows the comedic missteps and workplace hijinks of this around-thirty version of Haman, who must balance her authoritative persona with the trivial yet stressful demands of office politics and deadlines. The manga emphasizes humor derived from juxtaposing the grandiose conflicts of her source material against the relatable struggles of sales reports, meetings, and coworker relationships. The central character is this alternate Haman, while the supporting cast includes reimagined figures from the Gundam universe placed into analogous corporate roles. The publication, which began in October 2020 in Gundam Ace magazine, focuses on episodic, character-driven humor rather than mecha battles or interplanetary war.
