A group calling themselves the "New Ninja" tries to stop a vengestone smuggling mission while the ninjas attempt to deal with Nya's disappearance.

The ninjas' investigation into the vengestone smuggling mission leads them to an abandoned subway line — where they run into the New Ninja.

In a strange twist of fate, the ninjas successfully break Aspheera out of prison. But to save Nya, they'll also need to steal back Aspheera's staff.

As they wait in the monastery for the ninjas to return, Aspheera and Master Wu compete in a series of tests of strength and cunning.
