According to the local folklore of southwest England, pixies are small mischievous creatures that inhabit the countryside and woodlands that like to play pranks on humans. Depending on the tale told, pixies can vary in size from tiny enough to fit in the palm of a human's hand to the size of a small child, although they are always a good deal below the size of an average human. They can be portrayed with or without wings, and over the years have taken on many traits usually associated with fairies, often leading to the common misconception that they are one and the same.
Pixies are sometimes said to be born in much the same way as humans, however some tales tell that they are humans transformed through misdeeds or magic. They play pranks on humans such as stealing their belongings, throwing things or calling out their names. They may also steal horses during the night and return them by the morning with tangled manes. While pixies usually don't cause any real harm, it is said that if someone follows the voices of pixies, they will never to return.
Pixie is the lowest leveled Persona of the Lovers Arcana, on par with the starting Personas and can only be fused using low level Spell Cards and a gem that lowers the rank of the Lovers Arcana (example: Yoma Agathion + Spirit Poltergeist + Aquamarine). Despite the low stats when first fused, Pixie receives a noticeable increase in its Magic Attack and Luck stats as it ranks up, with a Magic Attack of 164 and a Luck stat of 94 at Max Rank (possibly more if the result of a beneficial fusion combination).
The Persona itself also differs from its demon counterpart, wearing the traditional leotard in a red color, along with matching long boots and short gloves. Returning a Max Rank Pixie in the Velvet Room yields a Luck Incense.
During the puzzle set up in Yoyogi Park, an old saying from Dartmoor; Pixie Led is played out. It was said that travelers that got lost on the moors were being led astray and turned around by the spells of mischievous pixies. In a similar manner, the pixies of Yoyogi Park lead the Demi-fiend astray by teleporting him to various locations if he passes below them.
The first demon you get in Nocturne is a Pixie, who wants to get out of the hospital and go to Yoyogi Park. She'll help you out in getting the card needed to get out. After you arrive at one end of Yoyogi Park, she'll try to part ways with you, but if you tell her you need her, she'll stay with you. For Nocturne Maniax, if you take Pixie (or one of her 'descendants') to a certain area of the Fifth Kalpa, she'll turn into a level 80 "super" Pixie.
Pixie can evolve into High Pixie through leveling up, and High Pixie into Queen Mab through the same method.
"In English myth, they are fairies of the forest that love to play tricks on people. They can also be hard workers when necessary."

Pixie appears as the demon recruitment tutorial as well as the first recruitable demon. It appears as a preset encounter in Sector Antlia, not far from the entrance. It first appears as an unknown entity unreadable to the Demonica's systems, but immediately makes itself visible to impart the tutorial. Afterwards, it's possible to recruit the Pixie.
Pixie will also issue the first possible EX Mission, The Injured Little Fairy, in which Pixie requests a Bead, which can be obtained as the spoils of the battle against Morax. Accomplishing this mission is rewarded with a Pixie Knife, a melee weapon that can inflict charm. Later, the same Pixie will evolve to High Pixie and begin issuing requests to bring Fairy demons to her so she can create a land for Fairies. Despite this detail, the player cannot obtain a High Pixie through direct evolution and must instead use Special Fusion.
