Luna (ルナ Runa) is a character from the movie Doraemon: Nobita's Chronicle of the Moon Exploration, she is Luca and Aru's older sister. Luna is voiced by Alice Horise.
Luna and her siblings were created by a scientist couple to aid in advancing and protecting the Kaguya planet. However, Diabolo, the planet's emperor, instead planned to use the siblings' Ether power to construct a powerful weapon in an attempt to rule over the galaxy. Fearing for their children's safety, the couples chose to send Luna and her siblings far away into space, much to their own sorrow. Luna and her siblings eventually arrived at the solar system. Though they originally had planned to live among the human on Earth, Luna and her siblings decided to live on the moon instead due to Earth's population. During this time, she also traveled to Earth by herself and became renowned as Princess Kaguya of the moon by the human. Because of them living in secrecy, the Espal were able to live in peace for almost 1,000 years on the moon, unable to age or die due to their long lifespan or perhaps immortality.
- Like another Luna before her, she is also Suneo's love interest.
