Idolmaster SP

Lore & Background

The narrative of Idolmaster SP centers on the expansion of the idol universe beyond the small office of 765 Production. A pivotal plot point is the introduction of 961 Production as a formidable rival agency. This version re-introduces Miki Hoshii, who now works for 961 Pro rather than 765 Pro. Additionally, two new characters join the fray: Hibiki Ganaha and Takane Shijō, both affiliated with 961 Pro. The distribution of these new idols is strictly version-dependent; Hibiki appears in Perfect Sun, Miki is featured in Missing Moon, and Takane is exclusive to Wandering Star. This structure forces players to choose which rival idol they wish to confront or recruit, fundamentally altering the story's dynamic compared to earlier entries.

In Their Own Story

In this installment, the player assumes the role of a producer managing idols from 765 Pro while navigating the competitive landscape against 961 Pro. The storyline emphasizes the rivalry between production studios, a recurring theme that deepens with the arrival of new characters. Depending on the version purchased, the player encounters specific rivals: Hibiki Ganaha in Perfect Sun challenges the player's progress, Miki Hoshii returns as an antagonist in Missing Moon, and Takane Shijō presents obstacles in Wandering Star. The plot also integrates a multiplayer aspect where up to three players can have their idols interact and audition together, adding a layer of social competition to the traditional single-player narrative arc.

Reader's Guide

Gameplay in Idolmaster SP retains the raising simulation roots but introduces significant changes to lessons and character management. Training an idol involves minigames designed to boost vocal, dance, and visual statistics, with the number of available lessons adjusted for this title compared to other entries in the series. The schedule phase allows producers to arrange daily activities, though specific options may vary from the original arcade game's limited choices. Communication with idols remains critical; text progression pauses when multiple responses are offered, requiring timely decisions that build mutual trust or create bad memories affecting future auditions. A new promise system is introduced in SP to further enhance these interactions. The audition phase serves as the primary method for climbing rankings and gaining fans through vocal, dance, and visual minigames. Successful candidates advance to televised public performances where player direction can influence the outcome.
