Transformation Ninja Sword Ninja Ichibantou

"Now, change!"

- Pre-transformation call

Transformation Shinobi Katana Ninja Ichibantou (変身忍刀忍者一番刀) is the transformation device and sidearm for the main five Ninningers.

Transformation
By inserting their activated transformation Nin Shurikens and pressing the red transform button on the Ichibantou, the blade announces "Now, Change!" (さあ、變化！), then a standby chant of "Nin nin nin, nin ninnin nin!" until the Ninningers spin the Nin Shurikens, which then releases the five elements of the Ninningers (Fire, Water, Wood, Metal, and Earth) and allows them to transform into their respective forms, as the Ichibantou announce the Ninningers being transformed.

Other Uses
The Ichibantou can be used to summon the Otomonin by inserting their respective Nin Shuriken into the sword and spinning it, allowing the Ninningers to ride the Otomonin by stabbing it into their Otomonin.

When forming Shurikenjin, the Ninningers insert the Ichibantou into special slots within the cockpit. The Ninningers also use the Ichibantou to play out Shurikenjin's finisher.
