-SHORT VERSION-
I like. But sounds strange.
-LONGER VERSION-
I usually like these references to other games.
But this Ami = Yuri.
Particularly the signature win pose. (and other move taken from her)
Again, I like the concept, but it would be even better if the characters can surprise the players with "new" animations.
However, using "more obscure" sources is ok (seifuku densetsu, Makeruna makendou, 3do sailor moon...), but in this case you cannot unsee Yuri.
And it's from my point of view slightly out of character.
