Marinette's life is beyond hectic. Go to collège, come home and work on the grimoire, fight akumas, eat and, if she gets the time, sleep. One night she has an epiphany. What if she could use the mouse Miraculous to divide and conquer? Creating a new spell with the help of magic cheese and Lucky Charm crackers, Marinette splits herself into three; Marinette, Nettie and Mari. With each unique 'version' of Marinette taking on one of her daily challenges it allows her to relax a little. That is until Nettie fixes her attention on Adrien, and Mari attempts to help in an akuma attack. The main issue though...each girl has a permanent piece of Multimouse attached to them which ends up being a little more revealing than expected.
