>>4141562For voiced content, there's the games. The games are the primary Idolmaster media. Not many of them are translated, but Chihaya's route in Idolmaster SP: Missing Moon is mostly translated. There's an ongoing translation project for One for All, as well. I can't recall if Gravure for You is translated or not.
A good handful of Chihaya's songs and covers are translated, as well.
For non-voiced content, there's some decent manga out there. Puchimas is very funny and worth reading, it centers on all 765 girls equally, more or less.
Chihaya has the lead role in a few doujin manga which are good and worth reading, too, and is a supporting character in others.
