Ninjago: The Master of Mind Power

After losing her memories, Yang Nian returns to the ninja world to find her memories and her younger sister.

The Su Lun clan, missing for many years, has appeared in the ninja world once again, clashing with the ninja time and again.

As dimensional fusion gradually brings all parallel universes together into one, danger follows.

Yang Nian's missing younger sister has also been turned into the weapon GA-2 by the Su Lun people, and the ninja fight against her.
