Ichika Hoshimiya works at S1 General Hospital, where she is constantly reprimanded by the head nurse for wearing her uniform too short, though she pays no mind to the criticism. Despite this, Ichika has a strong sense of duty and rushes to help any patient in need, personally providing care—sometimes even getting intimately involved when necessary. Adored by patients as an "angelic nurse," she's extremely popular. However, strangely enough, many patients at this hospital suffer from double arm fractures, hinting at a peculiar underlying reason. Meanwhile, Ichika continues her daily routine, busily attending to her patients' most private medical needs.
