Haruka Nishikikoji

A humorous, overweight and endearing school doctor who has made it his mission in life to assist his students in any way he can. Secretly in love with his childhood friend and pretty nurse, Miyuki, Doctor Haruka conjures up unique but crazy inventions meant to help his students and impress Miyuki but which often lead to humorous, funny and very embarrassing situations for the doctor, Miyuki and the students and teachers of his school. Managing a medieval castle-like clinic and health center, Doctor Haruka has often tried to express his feelings for Miyuki but is thwarted by both his shyness and the consequences of his crazy inventions.
