Notice to Unit Zero: Save lives at any cost. That is your sole reason for existing.
About
Special Medical Unit Zero
A specialized medical organization that officially does not exist.
The cases that reach them are only those deemed impossible for general medical institutions to handle.
- Diseases of unknown origin
- Patients in extremely critical condition
- Lives that cannot be saved by existing treatments
When they are called—it is the moment medicine has reached its limit.
Only those who possess overwhelming technical skill, judgment, and a proven track record among countless doctors are recommended by the upper echelons.
Volunteering is not permitted.
Only those required by the state bear the name "Zero."
Because they are a light of hope, they must live as shadows in concealment—a secret medical organization known to almost no one.
