Those trademarks Siliconera discovered were indeed for a localized version of The [email protected] Shiny Festa rhythm games. While these aren’t idol training sims, Namco Bandai made English versions of the PSP games. However, these won’t be available for PSP, the localized The [email protected] Shiny Festa games are for iOS.

There are three games – The [email protected] Shiny Festa Melodic Disc (called Groovy Tune in Japan), The [email protected] Shiny Festa Harmonic Score (called Honey Sound in Japan), and The [email protected] Shiny Festa Rhythmic Record (called Funky Note in Japan). Each one has a different set of idols and a different animated opening feature. If you thought Square Enix’s iOS games were expensive brace yourself because each The [email protected] Shiny Festa game costs $54.99. The complete The [email protected] Shiny Festa series will cost $164.97 and it appears the games will have additional DLC.

The [email protected] Shiny Festa Harmonic Score has idols Haruka Amami, Chihaya Kisaragi, Azusa Miura, and Ritsuko Akizuki with the "Music in the World" animated feature.

The [email protected] Shiny Festa Melodic Disc has Iori Minase, Yayoi Takatsuki, Ami Futami, Mamai Futami, and Hibiki Ganaha with the "Music is a Friend" animated feature.

The [email protected] Shiny Festa Rhythmic Record has Miki Hoshii, Yukiho Hagiwara, Makoto Kikuchi, and Takane Shijou with the "Music of Love" animated feature.

The games are compatible with the iPhone 4S, iPhone 5, iPad 2 (and higher iPads),the iPad mini, and fifth generation iPod Touch.
