MARs is the main Prism Show unit of "Pretty Rhythm: Aurora Dream". It consists of Mion Takamine (M), Aira Harune (A), and Rizumu Amamiya (R) (and an s for plural). MARs is an official unit of Pretty Top. They were on hiatus near the end Aurora Dream in order to focus on training for the championship, but restarted after Aira became Prism Queen by suggestion of Aira herself. All 3 agreed that that was the best course of action. And all of them have a love interest in the members of Callings. All members of MARs were born under the Skater Goddess Constellation.
At the suggestion of Aira, all 3 girls share matching bracelets, each matching to their theme color. This is a metaphor of their friendship. When Rizumu has to throw away her heart in order to jump the Aurora Rising, she takes off her bracelet in order to cut herself off. However, she puts it back on when she comes to her senses.
