Nin Shuriken

The Nin Shuriken (忍シュリケン) are small throwing stars used by the Ninningers to unlock their powers, forms, and Mecha by placing them into the Ninja Ichibantou, then spinning them. The Ninningers can also throw copies of their Transformation Nin Shuriken for various kinds of attacks.

The Nin Shuriken are divided into three types: Transformation Nin Shuriken (変化忍シュリケン), Technique Nin Shuriken (技忍シュリケン), and OtomoNin Shuriken (オトモ忍シュリケン). The Nin Shuriken were initally created by Yoshitaka Igasaki's friend, the weaponsmith Tetsunosuke Saika XXI, who is succeeded by his son Tetsunosuke Saika XXII. However, in certain cases, when the Ninningers sharpen their Nintality (忍タリティ) enough times, the purified Sealing Shuriken used to create Youkai can transform into new Nin Shuriken to expand their arsenal.

Sealing Shuriken
The Sealing Shuriken (封印の手裏剣) are the original set of 48 Shuriken which were used by Yoshitaka Igasaki to seal Gengetsu Kibaoni. Tainted by Kibaoni, they are used to create Youkai by combining with inanimate objects. Once the Youkai is destroyed, the Sealing Shuriken that forms its core is purified and the Ninningers must gather all of them in order to seal Kibaoni once more. Certain Sealing Shuriken can also transform into Nin Shuriken which adds to the Ninningers' arsenal or Yo Shuriken which are used by Kyuemon Izayoi to further the Kibaoni Army Corps.
