Kyoko Shirakawa works as a nurse at a hospital grappling with financial instability. Her career began in a sex club before the hospital director personally recruited her to deliver unconventional care designed to revitalize critically ill patients via sexual stimulation. Dubbed "special care," this method harnesses her vibrant personality, outgoing demeanor, and explicit emphasis on sexuality to emotionally connect with patients, despite her absence of formal medical qualifications.

She employs her physical presence and unrestrained approach to stimulate patients, with documented cases of success in reigniting their will to live. The director’s choice to enlist her services aligns with a pragmatic strategy to counter the institution’s fiscal challenges by elevating patient satisfaction through nonclinical interventions.
