Her move is called Pink Typhoon and not Pinky, isn't it? Pink Typhoon is also a famous song in Japan from the 70s that has gotten a lot of covers to this day because Pink Lady was huge. Trials of Mana and Slayers have Pink Typhoon related names, those are magic related so there you go. I don't think anyone in the thread is bringing you down or calling you crazy btw. Is just that your thesis has reached the point of seeing if there's something official supporting it or not. The Sailor Moon thing can be a connection or just a coincidence. But if you find something like the Sonic X concept art describing her attacks, abilities and hammer as magical girl related then you're golden. Or some random comment in a interview etc etc. I think it's better to put your efforts there instead of looking to connections to the genre.
