THE iDOLM@STER MILLION LIVE! THEATER DAYS (アイドルマスターミリオンライブ!シアターデイズ Aidorumasutaa Mirion Raibu! Shiata Deizu) also known as Mirishita (ミリシタ) is a spin-off free-to-play rhythm game distributed by Bandai Namco Entertainment for mobile devices based on THE iDOLM@STER: Million Live! franchise.

Both Android and iOS versions are released on June 29, 2017.


The game is a rhythm game where players tap notes in the rhythm of the background music. Different kinds of notes will be brought in to show how each icon must be tapped; these include simply tapping the icon, tapping and holding down the icon, tapping and flicking a certain direction, tapping two icons simultaneously, and tapping and sliding a certain direction. Different amounts of notes can appear during gameplay with a minimum of two and a maximum of six.

Additionally, after reaching level 5, the player can use a fixed amount of 20 energy to Work. The player can select Princess, Fairy, Angel, or All type work; upon selecting, a random girl from that type (or any type from All) appears, and the player gains affection and fans for her, alongside instant rewards. Occasionally, a communication- styled after communications from the main series- with the girl will appear and the player will get extra bonuses based on dialogue choices.

The player can also navigate the theater and offices to find girls to interact with: if a girl has a "..." bubble over her head this will reward the player with items and affection. Idols can also interact with each other. Finding the right idol to interact with is key to unlocking new main story commus.


There are three types of stories that you can unlock:

Main Story

The main story has the player work at 765 Production as the idol's Producer. Each chapter is broken up into three parts: Prologue, Main Story, and the Epilogue. The chapter's are fully voiced with each member's voice actress, and in order to unlock new chapters the player must either level up to the required level or wait for new chapters to be released. Each chapter in the main story unlocks a song.

Side Stories

Every idol has three types of side stories: Memorials, Episodes, and Outfit Episodes. Memorials are unlocked through gaining a certain amount of affection points for an idol, episodes are unlocked through awakening an idol's card, and outfit episodes are only available to idols with SSRs and are unlocked by liking their SSR blog post and then interacting with them.

Event Stories

Sometimes, events will come with new story to read. The chapters are unlocked through reaching certain point requirements. Each event story is made up of an opening, six chapters, and the ending.
