Takaharu informs the others that the title of Last Ninja is only obtained by defeating the previous holder and stealing their Nintality. The rest, just like Takaharu, are not capable of harming their grandfather. Then, Kyuemon Shingetsu Kibaoni appears. The Ninningers try confronting him but now that Kyuemon has mastered the Shuriken Ninpo as well, they have their powers sealed.
