Primera is a fairy who has acted as Lantis's guardian ever since he saved her from a monster attack. She's very jealous and possessive of Lantis and thus harbors a deep dislike for Hikaru. From the start, Mokona likes to tease Primera, causing her to greatly dislike Mokona. When Hikaru and Lantis start to become friendly with each other, she pops up to stop them out of jealousy, but Mokona either chases her away or eats her and later spits her out. She can use low-level healing magic when necessary.
Primera makes an appearance in Tsubasa in the Hanshin Republic and is later mentioned in the country of Piffle, by Shogo Asagi. Rather than being tiny, she is the size of a normal human.
In Tsubasa Chronicles, she usually appears with Shogo, as his lover.
