Where they realize that Yakumo's mother had the End Shuriken all along and decide to take it back.
The entire concept of magic vs. ninjutsu is silly, but there have been sillier concepts in Sentai. I thought it was handled pretty well, though.
Otherwise, a great episode. Yakumo and Kasumi's teamwork is nearly flawless now ("Mommy!" lol). I hope this goes on to the end of the series. I knew that Kasumi wouldn't be defeated just like that and was glad it happened.
So they have Kakuranger and Hurricanger attacks now?
