__Class:__ 6st-year Ha-class
__Committee:__ Health
__Occupation:__ Student, Medical Practitioner

Isaku is a 6th year student in Ninjutsu Academy. He is a gentle, caring and kind "big brother" figure to all his juniors. He always has a medical kit on hand, but forgets to bring along even the most essential ninja items. As the Health Committee chairman, he takes his job of giving aid to injured or sick people responsibly and fairly.

Rantarou, Shinbei and Kirimaru are ninja apprentices in the Ninja Gakuen, where first grade ones are called "Nintamas" (contraction of the words ninja+tama (egg). They must learn everything a ninja must know, but as for our heroes, money, food or playing are more interesting. The series show the everyday adventures of our heroes, segmentated in a cartoon fashion, like 2 small episodes in a 30-min show. The cast also includes the teachers (Doi-sensei and crossdressing Yamada-sensei), nintama kunoichis, evil guys (Dokutake ninjas) and even family members of all the cast...
