Ester is an albino rabbit. She is also Umarekawaru's (Sailor Easter) guardian. Both are from 31st century Crystal Tokyo. In the 31st century and when she gets brought back to the present, she calls Luna and Artemis, Auntie Luna and Uncle Artemis. Ester, although talkitive with Umarekawaru (and her family), Luna, Artemis, Diana and (in the future) Salem, is very shy around strangers.
