WM (pronounced Double M) is an idol unit consisting of Mikuru Natsuki and Mizuki Kanzaki. The unit debuted in the Data Carddass Aikatsu! 2014 Series - 4th collection and in Episode 78 of the anime. The unit had officially disbanded after the Twinkle Star Cup that ended on Episode 100, and had made a special one-time performance in Episode 173.
Mikuru and Mizuki first met when Mizuki was still a student of Starlight School. She was preparing for a concert, but was having difficulty choosing the coord she should wear when Mikuru showed up delivering flowers. After the then florist took notice of the cards, Mizuki explained about how the coords were supposed to make her shine, but can only show the sides her fans have already seen. She then stated that she wanted to change but couldn't. Mikuru smiled after hearing the idol's problem and asked her if she would like to see Mikuru's Miracle, in which she then proceed to prepare a Good Coord for her.
Afterwards, Mikuru watched Mizuki's concert and was amazed at how she could smile to so many people, which was a contrast to the one-on-one smiles she brought to the customers at her shop.
At some point, after she left Dream Academy, Mizuki went to find Mikuru and form their unit, WM.
