Synopsis
After the defeat the team suffered against Raizo Gabi, Tsumuji has brought two new ninja teachers: the Kakurangers’ Sasuke/NinjaRed and the Hurricanegers’ Yousuke Shiina/HurricaneRed. After seeing the Ninningers in action, the teachers sternly declare that the team lacks strength and that Takaharu is not even up to par.

Plot
The Ninningers train themselves to get stronger in order to surpass Raizo in their next encounter. Fuuka tries to express her gratitude to Takaharu for saving her earlier, but to no avail due to her in-confidence. Tsumuji ends their training and presents to them two new teacher; Yousuke Shiina (HurricaneRed) of the Hurricanegers and Sasuke (NinjaRed) of the Kakurangers.

The two Sentai Red veterans demonstrate their proficiencies in their respective techniques and teach the Ninningers to master it. AoNinger even tries an air technique until HurricaneRed scolds him for the use of magic spells. While Raizo is nursed back to health, Kyuemon remembers Yoshitaka's claims that he knows nothing of the Shuriken of the End. The Ninningers receive their report cards with Takaharu being the lowest, but still willingly awaits for harder tasks. Elsewhere, a new Youkai named Nekomata is born from an abandoned watch.

The Ninningers and Sentai Reds are alarmed by his presence, but Takaharu is tied up and forced to stay at the dojo by his teachers. Kyuemon approaches Nekomata and asks him to fulfill a task, which he accepts. The Ninningers and their teachers arrive, but are overpowered by Kyuemon. As Nekomata goes into the past, Takaharu races into the time door. Sasuke and Yousuke watch in regret as they reveal what will happen to Takaharu: Nekomata leapt into the year 2005 to attack any ninjas in order to search for the Shuriken of the End. As NinjaRed and HurricaneRed were the only available ninja left, Takaharu from the future assisted them in the battle. As Nekomata got the Shuriken and tried to return to the future, Takaharu tried to hold him off but was seemingly killed in the battle. What remained of AkaNinger was kept by Sasuke, which was his burnt report card.

Yakumo can't believe it, even when the returned Nekomata confirmed his demise. But Takaharu reveals himself to be alive, having uses the Clone Jutsu to fake his death and quietly sneak into Nekomata's time door. After destroying Nekomata, two Sealing Shuriken transform into Legend Nin Shurikens that represent the Ninningers' Sentai Ninja predecessors. Kyuemon realizes that what she got was NinjaRed's precious Shuriken instead of Yoshitaka's Shuriken of the End.

Kyuemon summons Giant Youkai Gashadokuro again before leaving as the Ninningers summon their Otomo Nins to form Shurikenjin. Under NinjaRed's advise, AkaNinger uses his newly received Nin Shuriken before finishing Gashadokuro with the Shurikenjin: Splendid Slash!.

NinjaRed and HurricaneRed leave the Ninningers on their own. They reunite with Akarenger as Yoshitaka thanks them for teaching his grandchildren and witness the Ninningers from afar.
