Her signature odango hairstyle, iconic transformation sequences, and catchphrase "In the name of the moon, I'll punish you!" have become legendary in anime history. Her relationship with Tuxedo Mask and her friendships with the other Sailor Guardians showcase themes of love, friendship, and believing in oneself that have inspired generations of fans worldwide.
