Trivia
In a proposal by Toonmakers, Inc to dub Pretty Guardian Sailor Moon, there is a white cat seen in the proposal clip. It is unknown whether this is supposed to be Luna or Artemis, or a combination of the two.
Artemis is a Greek feminine name- "Meaning unknown, possibly related either to Greek αρτεμης (artemes) "safe" or αρταμος (artamos) "a butcher". Artemis was the Greek goddess of the moon and hunting, the twin of Apollo and the daughter of Zeus and Leto. She was known as Diana to the Romans." (www.behindthename.com)
