Etymology

 * Luna's surname Mitsuya means "three" (三) (mi), "stars" (ツ) (tsu) and the kanji of (谷) (ya) means "valley".
 * Her given name, Luna, is spelled in katakana, so it doesn't hold any particular meaning in Japanese. In various other languages however, like Latin and Spanish, "luna" means "moon".
