Coco

Coco is a small yet very fast barefooted girl who serves as a messenger, among other things. Her title is Assistant Chief of Staff, putting her only a rank below the wizened Byro in standing. She seems to either be incredibly agile or perhaps has Magic which pertains to speed in some way. She is also very hyperactive, sprinting from one end of Faust's throneroom to the other just to respond to a question.

Apperance
Her face's appearance bears a distinct resemblance to a puppy, with a small black nose and some kind of headwear having large, floppy "ears". The greater significance this has to her actual character is unknown.

Edolas arc
Coco is first seen reporting the increase in magic. Faust responds that he needs more still. Later she takes part at the Royal Army Captains' meeting, commenting on the good progress of the Dragon Slayer Magic extraction. When Faust and Byro wanted to use the Edolas Magic Chained Dragon Cannon to crash the floating island with Lacrima-ed Fairy Tail members, she protested, becouse she didn't want to kill Pantherlily, who was currently fighting there. She stole the key, and ran away. Faust tried to stop her by injuring her legs, but it didn't work. Later, she crossed paths with Lucy, and asked her for help. Byro arrived right after and asked for the "key". Lucy misunderstood and thought that Byro wanted to have her Celestial Spirit Keys, and prepared to fight him. After Lucy and Natsu defeats him, Coco and Lucy get stuck under his tentacles. Coco comments that they are stuck partly because Lucy has big boobs. After she rescues Lucy, Coco began to aid Team Natsu by helping them escape and transport them to the Lacrima Island with her Legion flying beast. Coco asked her Legion Flying Beast to stop the Lacrima Island, but to no avail. As the Lacrima Island continues to crash, she noticed Pantherlily was yelling at her for doing something that foolish. Coco replied that compared to Infinate Magic, she would rather have Infinate Smiles. After Mystogan stops the Lacrima, while crying she, says "The prince has returned." Coco helps Lucy and the others during the invasion of the Edolas troops. After Mystogan "defeats" Natsu all magical creatures return to Earthland. Coco waves goodbye to Earthland Fairy Tail as they get transported back home.

Trivia

 * The aforementioned resemblance to a puppy could reflect Coco's vast stores of energy and tendency to make exaggerated actions.
 * When she fought Byro with Lucy, Virgo was summoned and she did her usual "Did you call for me, Hime?", which made Coco think Lucy is an actual princess. When saying goodbye to Exceed and Earthland people, she called Lucy 'Hime', which concludes that the misunderstanding was never cleared up.
