Basu wo orita shunkan mishiranu machinami
Itsu ka mita you na garasu no biru
Michi ni mayotte bakari itsu ka mo kurete
Hayai zawameki ni namida ga deta

Dare mo tayoranai koto ni akogareta
Da kedo chippoke na kutsu ga ame ni yaburesou

Sekai-bun no ichi no boku wa koko da yo
Sora wa boku wo mite iru
Sekai-bun no ichi no yume wa itai yo
Honto wa kowai keredo
Donna ni naite mo ii
Ima shika dekinai tabi ga shitai

Denwa box no naka koin mo nai no ni
Hanasu-buri shite wa ama-yadori

Fui ni yasashiku sareta yo "kaerou" to
Donna hito mo hajime kara otona ja umarenai

Sekai-bun no ichi no boku ga suki da yo
Motto sunao de iyou
Sekai-bun no ichi no deai ga aru yo
Ano toki ni iezu ni ita
Arigatou wo itsu demo
Dare ka ni kaeshite ikite yuku yo

Sekai-bun no ichi no boku wa koko da yo
Sora wa boku wo mite iru
Sekai-bun no ichi de okoru dekigoto
Minna uketomete iku
Kanashii hi mo aru kedo
Boku shika dekinai tabi wo shiyou
