The Idolmaster Million Live! Theater Days is doing much more than posting a celebratory image for its ninth anniversary. The June 29 and June 30 campaign material lays out an entire anniversary structure with a special PV, a limited-time event, mission-based rewards, ranking prizes, login gifts, and paid-gacha promotions.
That matters because these game-anniversary stories become useless fast if they do not separate atmosphere from mechanics. The official release actually gives enough structure to explain what players can do right now and what deadlines they need to keep in mind.
What The Announcement Actually Confirms
Official Million Live! Theater Days 9th-anniversary release says the game marked its ninth anniversary with a new special PV and then rolled directly into the limited-time event 最上級：Invit@tion! beginning at midnight on June 30, 2026.
The release also makes clear that the anniversary is being handled as a layered reward campaign. It is not just one event song and one login gift. There are daily anniversary missions, event-point rewards, idol-specific ranking rewards, global milestone rewards, and companion store promotions running alongside the in-game content.
The full Japanese announcement lists the currently announced details available so far.
Confirmed Details
- Anniversary PV went live for the 9th anniversary on June 29, 2026.
- Main limited-time event start: June 30, 2026 at 00:00.
- Event song: Dress Code: Saijokyu, with 52-idol vocal support and solo performance handling through the center-idol setup.
- Reward tracks include cumulative event points, high-score ranking, lounge ranking, daily anniversary missions, daily event-point rewards, and idol-specific rankings.
- Anniversary login gift window in the release: June 29 to July 12, 2026.
- The ’39 Gasha Vol.2′ promotion runs through July 31, 2026 and sells a special pull for 390 paid jewels with a 39% SSR rate.
This anniversary is structured around sustained participation rather than one login day, with several of the better rewards tied to repeated point gains, daily mission clears, or ranking engagement over time.
The game’s internal terms also become clearer when translated into plain functions. Morpho Ruban is the event currency, the anniversary card is the prestige collectible, and the mission pages gate several of the better rewards.
What Has Not Been Announced Yet
Exact fine print for every reward path still sits in the in-game notices and event pages.
The public campaign outline already confirms the anniversary dates, reward systems, ranking tracks, and login windows.
