The "one who yells on Youtube" is named Winter, and her wife is my sister, Lily Tsukuyomi. But you're right, I am a Precure.

And yeah, I've seen something like it, but none with those specific features. It doesn't look like anything I've ever encountered. This may be hard to follow, but there are multiple universes where there are Precure... this is probably from a world that's similar to mine but not exact.
