Anorexia, narcolepsy, Bell’s palsy... Elementary schools are full of illnesses most people have never even heard of.
One day, a mysterious and troublesome doctor named Makino arrives at the school infirmary, the last line of defense protecting the children’s future.
Strange, unnamed illnesses quietly creep into the daily lives of the students.
Dr. Makino, with a big mouth and an even bigger attitude, may seem detached, but he still faces the subtle signs of these overlooked conditions head-on... or does he?
