"Flowers are short-lived but so pretty while they last and their beauty makes people happy. Why would anyone take a wonderful flower and make it into a killer?! I won't allow these plants to be used for evil! That's gonna give florists everywhere a terrible reputation! In the Name of the Moon, I'll punish you!”
— Usagi Tsukino
