"Have you ever thought about what makes a Pure Heart? To me a Pure Heart is something that comes from the love and friendship you feel towards others. It gives me the strength to overcome anything. And remember, even if you return to the future, our hearts will always stay connected. Bye Chibi-usa, please take care!”
— Usagi Tsukino
