Mimi

Mimi is Lulu Bell's faithful Akuma. While her spirit is that of a servant, her body is that of a princess. Making her existence as Lulu Bell's maid/manicurist somewhat ironic.

Appearance
She has pale blue hair that she keeps in pigtails with pale skin, red eyes, pointed ears and is wearing a sterotypical maid's uniform. Unlike most Akuma she has two Akuma forms, the first of which involves her skin turning to a dark metalic gray and her sclera turning black. In this form she produces two war fans to fight with. In her second Akuma form she takes the form of a large robotic dragon.

Background
Mimi, like all Akuma, began life as two seperate people. Her outward body was originally a princess of some unknown land, but when her trusted maid servant fell ill and died, she was of course approached by the Millennium Earl. Accepting his contract, she called back her servant's soul and the two became an Akuma. From there Mimi would've killed humans until obtaining Level 2 and regaining some sort of persona. It was sometime after this that she met Lulu Bell, who asked that she do her nails for her. Happy to be needed, Mimi from then on became Lulu Bell's faithful servant and personal Akuma it seems.

Lulu Bell's Attack Arc
Mimi was the one with Lulu Bell, atcking the exorcists. She was the reason for Lulu Bell's victory for stealing Meilin's crystal ball

Abilities and Powers
She fights wielding two steel fans which she uses as projectiles, throwing them disc-like towards opponents or launching their spiked tips like darts. Her akuma form of a giant metalline dragon allows her to manipulate wind with her wings; a continuation of her steel fan fighting. When specifically protecting Lulu Bell, her dragon form glowed orange and displayed increased power; her normal form became more like a Noah with dark blue skin and an insane grin. She became both faster and stronger with her fans, slashing at close range against Allen.

Trivia

 * Mimi is similar to the Noah in the sense she has an intermediate form between her "human" and Akuma forms.
