Detective Sakuta Jiro, a sharp investigator in the prefectural police's First Investigation Division, spends his days on stakeout surveillance. His only small pleasure during these long hours is the homemade character bento he prepares for himself—octopus-shaped sausages, cat-shaped croquettes, and bear-shaped rice balls made from premium Koshihikari rice, each crafted with care from carefully chosen ingredients. The quiet routine is disrupted when a highly motivated new subordinate joins his team, making it much harder to enjoy his cute lunches in secret while on the job. In the second volume, Sakuta unexpectedly gains a bento companion who shares his passion, leading to new recipes and shared meals. He later creates a special sandwich for a junior colleague who dislikes bread, and at Christmas he celebrates with his new bento friend. A forced arranged marriage meeting brings an unexpected encounter, and finally Sakuta meets the person he has long admired, setting the stage for major changes in his life. The story intertwines the daily realities of police work with the gentle, comforting ritual of preparing and eating lovingly made character bento.
