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 Lulubell's maid/manicurist somewhat ironic.

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 Lulubell's faithful servant and personal Akuma it seems.
