The series focuses on the male idols of 315 Production, in contrast with the normally female idol centric series.^[1]

The original game was published by Bandai Namco Entertainment and developed by Alt Plus Inc. was released on the Mobage platform in 2014.^[2] and is a male idol raising simulation game. A second game, a rhythm game developed by Akatsuki, was released in August 2017.^[3] An anime adaptation by A-1 Pictures aired between October and December 2017,^[1] and a second chibi slice of life anime adaptation of a manga, animated by Zero-G, aired from October to December 2018.^[4]

The series follows the male idols and the producer and staff of 315 Production (315プロ, Saiko Production) and their activities as idols, including concerts, events, and stage productions. The idols are grouped into set units, although they are not limited to working within these groups.

Some of the idols are from other series; the Jupiter trio from Idolmaster and Ryo Akizuki from Dearly Stars.

The game is a free-to-play raising simulation in which the player, as the producer, collects idols and completes work tasks. In the games, the idols are individually categorized into one of three attributes: physical, Intelligent, and Mental. Idols are collected through cards that are ranked by rarity, strengthened through lessons, and do work for resources. Idols can 'battle' other idols in auditions, live concerts, and in battles against other players.^[8]

The game also contains a mini-game called SideMini, in which miniature versions of the idols bring the player items.

Within the game exists manga about the idols in the form of 'magazines' that can be unlocked via gameplay items.^[8]

The game originally opened on February 28, 2014, but due to difficulties arising from an unexpectedly large number of players, the game was closed a day later^[9] and reopened five months later on July 17, 2014.

A version for feature phones was available from launch until June 7, 2016. Around the same time, a Chrome app version was released on May 4.^[10]
