A salaryman so broken by corporate life that he demands spreadsheets in a fantasy kingdom is the funniest possible response to isekai wish fulfillment. The show gets that some people's damage runs deeper than any magic system can fix, and that watching someone slowly realize their addiction was the actual curse, not the solution, hits different than another hero's journey. By the time he stops treating Romany like a quarterly report, you've stopped treating this like every other portal fantasy that came before it.
Kondou Seiichirou has spent his twenties chained to a corporate desk, and it shows. When a summoning ritual yanks him into the Romany Kingdom, he doesn't waste time sightseeing. Instead, he lands a job as an accountant for the royal government, ready to bring order to their chaotic books. His obsessive work ethic makes him invaluable, but it also leaves him desperate for any edge against the crushing fatigue that follows him even here. A magical tonic promises relief. It works almost too well, erasing his exhaustion completely. But Kondou's body has no natural defenses against this world's magic, and the tonic starts poisoning him from the inside. His only survival option requires finding someone willing to attune him to magical energy through close, repeated contact. As he navigates workplace politics and the strange customs of a fantasy kingdom, Kondou discovers that escaping the grind means learning to actually live first. Balancing ledgers turns out to be simpler than balancing a life that finally has room for something beyond work.
