Shinobi 15: Youkai, I Never Failed (妖怪、ワタシ失敗しないので Yōkai, Watashi Shippai Shinai node) is the fifteenth episode of Shuriken Sentai Ninninger.




While Kasumi helps Nagi and Fuuka in their studies, StarNinger tries to assassinate them, with the period given by Yoshitaka is about to end but fails. Kasumi quickly pins his shadow before releasing him back to target Takaharu. Elsewhere, Aka and AoNinger try to find the Sky OtomoNin in hopes of taming it under Yoshitaka's orders. Masakage and Kyuemon spot them, as the former plans to take control one of them. StarNinger tries to attack them, but knowing they were occupied by their own works, he decided to leave them alone.

Masakage creates Youkai Futakuchi-onna and orders her to gain control of one of the OtomoNin. With a Youkai detected, StarNinger lets Rodeomaru return home while he rushes to the scene himself. As Rodeomaru did so, Futakuchi-onna approaches him and offers a deal. As the Ninningers gather at the place where Futakuchi-onna first appeared, Kyuemon summons a Gashadokuro, which uniquely this one has a pair of eyebrows. StarNinger tries to summon Rodeomaru but to no avail, with the Ninningers summoned theirs and Rodeomaru arrives late, with Futakuchi-onna besides him acting as his negotiator. It was revealed that she had made him under her control after revealing him the poor treatment StarNinger gave to him in the past, battling Youkai and did labour works. With more troubles arises, AkaNinger decides the group to split, where he battles Rodeomaru with Shinobimaru, Yakumo and Kasumi deals with Futakuchi-onna and Ki and ShiroNinger deals with Gashadokuro as Aka gives them some of his Nin Shuriken.

Ki and Shiro use Kakuranger Nin Shuriken, splitting themselves to fill in the empty seats in Shurikenjin and summons Paonmaru and UFOmaru to help them, using auxiliary combinations per switch but even though they win, the Kakuranger Nin Shuriken greatly exhaust their energies. Futakuchi-onna prepares a contract for Kinji to sign in order to regain Rodeomaru, but Yakumo and Kasumi stop them, as they become Kinji's attorney in an agreement. Unable to stand any longer seeing Rodeomaru gone wild, Kinji quickly signs the contract and quickly fell under it's effects, turning into a rampant. Futakuchi-onna prepares another contract for Yakumo and Kasumi to sign for their comrades to return back to normal. Rodeomaro summons a Bison Rifle and destroys the Shurikenjin combination before setting it's target at Shinobimaru. While Kyuemon collects humans fears, Masakage orders him to create another Gashadokuro as it attacks again and with Rodeomaru, attacking the OtomoNins.

An idea hits Kasumi, where she tricks Futakuchi-onna by pretending to give up and surrenders. Amazed by her words, Futakuchi-onna removes her spells, until she realizes too late. StarNinger and Rodeomaru regain their senses and with BisonKing, StarNinger kills Gashadokuro while the Ninningers taken care of Futakuchi-onna and destroys her with Ninja Ichiigeki. Kinji meets Kyuemon, where he reveals that his reason of betraying Yoshitaka was due to his fear of not lending him the End Shuriken, since he is not from the Igasaki clan and thus, she deduces that Yoshitaka betrayed him first and that he is afraid of him. She also proposes Kinji as his pupil, knowing that he is also after the End Shuriken and leaves. The other Ninningers regroup with him where Kasumi returns his hat before they return home.

      • Futakuchi-onna is psychologically manipulated by Masakage to fight for him and by Kasumi to give in in the end; while similarly it is later revealed that Twilight was the lost Hope Kingdom Princess Towa Akagi, who had been brainwashed and manipulated since childhood into working for the villain group Dys Dark; after breaking away, she later becomes the heroic Cure Scarlet.
