Legend Days is a idol unit that appears in THE iDOLM@STER: Million Live! social mobile game. The unit consist of Ganaha Hibiki, Futami Ami, Minase Iori, Takatsuki Yayoi, and Akizuki Ritsuko. This unit's story is told through skits in the game. Additionally, they also have an unit CD, THE IDOLM@STER LIVE THE@TER HARMONY 01.
Legend Days was formed in response to a new event, the Platinum Star Live. Led by Hibiki, it is an energetic unit that has a strong dance focus. However, while preparing for the live, Hibiki began to feel like they weren't quite perfect yet, though she couldn't pinpoint a reason why. The producer suggested that they go somewhere as a group and gain life experience, as well as grow closer as a unit. After Hibiki, Ami, and Ritsuko took a trip to Akihabara, the girls were able to learn more about being idols.
