Human body cells never pause for long; each day brings fresh tasks and lessons, as the system constantly adapts. That is the reality Hakkekkyuu U‑1146 experiences as he darts back and forth, hunting any pathogens that might threaten the organism, ensuring its stability. Though his job is perilous, it is worthwhile to safeguard the bright smiles of Sekkekkyuu AE3803, the platelet squad, his fellow neutrophils, and every other cell he encounters for their collective well‑being. During his latest pathogen‑tracking missions, Hakkekkyuu U‑1146 learns that even vital cells can err and that not every bacterium is harmful, sometimes playing protective roles. Everyone endures rough moments, yet all resolves when allies support one another, reinforcing the body's resilience. Ultimately, it remains just another ordinary day for these diligent cells, continuing their ceaseless duty!
