The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

Third Senior Sister is seductive, enchanting to the extreme, yet is actually a crude tomboy who uses brute force.

Fourth Senior Brother is shockingly handsome to others, but in private, he is a proud, battle-crazy glutton with a poisonous tongue.

The Zhu Zhu who looks very homely and unrefined was forced to live life among this group of beautiful people; it could be said the pressure was huge.
