Bài hát: Sora - The Idolm@ster

Sora ni naritai jiyuu na sora he
Tsubasa nakute toberu kara suteki ne
Sora ni naritai sukina sora he
Kumo de yume egakeru kara

Hajimari ha doko ni naru no?
Oshimai ha doko ni naru no?
Ue wo mite anata ni kiitemitara
Hajimari to oshimai nante
Tsunagatte meguru MONO
Daiji nano ha yametai koto to
Akiramenai koto

Haru ha hana wo ippai sakaseyou
Natsu ha hikari ippai kagayakou
Kiseki janakute un janakute
Jibun wo motto shinjiru no
Aki ha yoru wo meippai norikoe
Fuyu ha yuki wo meippai dakishime
Waratte ii yo naite ii yo
Datte megutte mata haru ha kuru kara
Tsunagu REINBO-

Sora ni naritai hare no sora he
Namida kawakashite ageru muteki ne
Sora ni naritai ame no sora he
Egao dakeja samishii kana

Imi ga nai to DAME desuka?
Kotae nai to DAME desuka?
Mae wo mite anata ni kiitemitara
Imi ya kotae to iu no ha
Ato kara tsuitekure MONO
Hitsuyou nano ha tatta hitotsu
Sono kokoro dakesa

Hana doko datte tane wo mawase yo
Hikari ha doko datte yami terasu yo
Watashi no mama ni i no mama ni
Jibun ni chanto sunao ni
Yoru ha itsudatte asa ni kawatte
Yuki ha itsudatte ibuki nokoshite
Ichihi izutsu ippozutsu
Kikkake ha nan datte daijoubu
Tsudzuku REINBO-

Haru ha hana wo ippai sakaseyou
Natsu ha hikari ippai kagayakou
Kiseki janakute un janakute
Jibun wo motto shinjiru no
Aki ha yoru wo meippai norikoe
Fuyu ha yuki wo meippai dakishime
Waratte ii yo naite ii yo
Datte megutte mata haru ha kuru kara
