“Who are you? Are you a Sailor Guardian? Did you just say that Chibi-usa's mind is in danger? What do you mean by that? Don't worry Chibi-usa. Have faith in us! Because all of us will protect you no matter who is after you. We'll see to it that you never get hurt! In the Name of the Moon, we'll protect you!”
— Usagi Tsukino
