The Idolm@ster SP: Missing Moon is the third and final piece of the SP trilogy. While Perfect Sun is energetic and Wandering Star is mysterious, Missing Moon is often considered the “emotional” or “melancholic” version, featuring the most complex character dramas in the portable series.

The “Missing Moon” Roster

This version contains the fan-favorites known for their deep backstories and high difficulty:

Chihaya Kisaragi: The “Cool” idol who lives only for singing. Her story is famously dramatic and emotionally heavy.
Azusa Miura: The older, “big sister” type with a terrible sense of direction but a heart of gold.
Ritsuko Akizuki: The brainy, glasses-wearing idol who manages herself and focuses on the business side of the industry.
The Rival: Miki Hoshii, a “genius” idol who originally belonged to 765 Pro but defected to 961 Production due to a misunderstanding with the Producer.

📝 Game Description

As the Producer, you navigate the high-pressure world of 765 Production. Missing Moon follows the established SP loop of Lessons, Communication, and Auditions, but with a distinct narrative flavor.

Key Highlights:

The Miki Conflict: Unlike the other versions where the rival is a stranger, Miki Hoshii is your former student. Seeing her perform for the rival agency (961 Pro) adds a layer of betrayal and urgency to the Story Mode.
Vocal Focus: Because Chihaya is the “Vocal Queen” of the franchise, this version places a heavy emphasis on the Vocal stat. You will spend a significant amount of time mastering the rhythm-based Vocal lessons.
The “Tension” Management: The idols in this version (particularly Chihaya and Ritsuko) are prone to mood swings if you fail an audition or pick the wrong dialogue. Keeping their “Tension Gauge” high is a constant balancing act.

⭐ Short Review: The Emotional Powerhouse

The Good

Best Storytelling: Chihaya’s route is widely regarded as one of the best-written stories in the entire Idolm@ster franchise. It explores her personal trauma and her journey to find joy in music again.
Top-Tier Music: Since Chihaya and Azusa are the strongest singers in the group, the song list feels particularly impactful in this version.
Strategic Depth: Ritsuko and Azusa require very different playstyles, offering high replay value for those who like a challenge.

The Bad

High Difficulty: Chihaya is notoriously difficult for beginners to manage. If her tension drops too low, she becomes very hard to recover, which can lead to a “bad end.”
Miki’s Defection: For long-time fans of the series, seeing Miki as an antagonist can be genuinely frustrating (though it makes for a great story).
Menu Navigation: Like the other versions, the menus are entirely in Japanese. While there are translation patches, the sheer amount of technical text for stats can be overwhelming at first.

Verdict: Missing Moon is for the players who want more than just a pop-star simulator. It offers the most “mature” and dramatic narrative of the three PSP games. If you want to see the emotional soul of The Idolm@ster, start here.
