Shuriken Sentai Ninninger

With the passing of the Last Ninja, the Yokai Army is freed once again and it's time for the five descendants of Last Ninja, Takaharu, Fuka, Yakumo, Matsuo and Kasumi to become the Ninningers and protect the world from the Yokai Army. Takaharu returns to his hometown when a horde of ashigaru attack.

After their first encounter with the Yokai Army, the five Ninningers train at the Ninja Dojo. Takaharu gives some Ninjutsu advice to the others but Yakumo, who is a genius about that, doesn’t agree with him. The five heroes start their ninjutsu training. However, Takaharu confronts Yakumo, who's standoffish attitude has worn thin.
