A spin-off series showing the daily lives and work of the platelets.

The gag comedy is set in a school nurse's office (hokenshitsu). A strange nurse deals with the unique issues of the female student body, such as a self-absorbed eye-patch-wearing girl, a character with frequent nosebleeds, a shy but well-endowed girl, and others.
