Otome Storm! is a unit that appears in THE iDOLM@STER: Million Live!. The members of this unit are Kasuga Mirai, Ibuki Tsubasa, Nanao Yuriko, Makabe Mizuki, and Mochizuki Anna. 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 02.
Like Legend Days, Otome Storm! was formed in response to the Platinum Star Live. After some doubt over Mirai's ability to lead the unit, the others came to accept her.
