Let the Moon Rise, Little Ninja

Given the chance to enter Prince Wu's academy, Nya devotes herself wholeheartedly to her studies, trying to prove that she's worth the effort (If Sensei Wu had trained Kai to find his cutie mark, why couldn't he train her?).

But when her studies led her to uncover the old prophecy of the Oni in the Moon, she couldn't help but worry. Two letters and one burnt breakfast later, she, her brother, and their resident green bean Lloyd are being sent to Ninjago City to "relax."

But how can Sensei Wu expect Nya to "relax" when disaster is about to strike?

But maybe, just maybe, this trip to Ninjago City would turn out to be better than she expected.

-Or-

A Ninjago MLP crossover because why not :D
Sensei Wu takes the role of Celestia, so he won't have as big a role in here compared to his role in the Ninjago Netflix series.
Hope you enjoy this just as much as I will
