Otona ni nanka naritakunai to
Ii tsudzukero! We're growing up

Imi mo naku garasu wo wattari
Abarete iru'n ja nai
Mono wakari ga ii no wa iya da
Hankouteki we're growing up

Me no mae no sekai wa
Kyoukaisen de shikirareteru
Ikutsu mono kanaami ga
Yaritai koto jama suru'n da

Koko ni itatte
Taikutsu da
Sabitsuita ruuru nante
Penchi de kitte yaburou

Bokura wa mou kodomo ja nai'n da
Jibun no ashi de arukou
Dare no sashizu mo ukenakute ii
Itsunomanika we're growing up
Jiyuu to wa wagamama to chigau
Hitori de kangaeru koto
Ikitai basho mitsukatta toki
Souda sore ga we're growing up

Chizu ni aru sekai ga
Subete datte shinjiteta
Hontou no shiawase wa
Souzou no soto ni aru'n da

Kaze wo yokogiru
Tori-tachi
Habataita sora no mukou
Soko kara nani ga mieru ka?

Bokura wa mada otona ga kirai da
Kagami wa nozokitakunai
Zettai yogoshitakunai kedo
Masshiro ja nai we're growing up
Sukoshi zutsu toshi wo tori nagara
Jitabata ikite ikitai
Me wo hiraite ima demo zutto
Yume wo miteru we're growing up

Bokura wa mou kodomo ja nai'n da
Jibun no ashi de arukou
Dare no sashizu mo ukenakute ii
Itsunomanika we're growing up
Jiyuu to wa wagamama to chigau
Hitori de kangaeru koto
Ikitai basho mitsukatta toki
Souda sore ga we're growing up

Raku na hou ni ikitakunai yo
Teikou shinagara we're growing up
