Shuriken Sentai Ninninger Episode Previews

I hope you aren't sick of ninja sentai yet... Anyways, let's look back on Shuriken Sentai Ninninger!
Note: This series served as the source material for Power Rangers Ninja Steel/Super Ninja Steel.

Note: The idea to make sentai episode preview videos was inspired by another channel that made videos like this.
However, since it doesn't look like those videos are up any longer, I decided to make some of my own as they're a nice way to quickly experience a sentai, "re-live" a sentai, or explore the contrasts between a sentai and its Power Rangers adaptation.
I can't remember the name of the channel, but, if you're reading this, know that I'm trying to give you credit.
