Centuries ago, the ruthless feudal warlord Gengetsu Kibaoni was slain by the Igasaki Ninja clan, before discarding his humanity to become a Yokai.

As only members of Igasaki's bloodline can stop the rampaging Yokai, Yoshitaka's son Tsumuji Igasaki assembles the Ninningers, composed of his children Takaharu and Fuka and their cousins Yakumo Kato, Nagi Matsuo, and Kasumi Momochi, to master their clan's Shuriken Ninja Arts (手裏剣忍法, Shuriken Ninpō) and fight the Kibaoni Army Corps.

The team is later joined by Kinji Takigawa, a Yokai Hunter from the United States who becomes Yoshitaka's disciple after earning his trust.

Takaharu gets into an argument with Kinji over which of them has the better fashion sense before they come across Kamaitachi, Tsuchigumo, and Kappa with an army of Jukkarage, Dorodoro, and Magareppa that have all been revived from the magic of Hyakki Yagyō in daytime due to Kibaoni's influence.

In the film's storyline, Fuka and Kasumi form a group called the Ninnin Girls and challenge their male teammates to a showdown.

At the same time, Ariake no Kata, Mangetsu Kibaoni, and Juza Yumihari have revived and intend to take revenge on the ninjas.
