Zutto tobira wo akeru kagi wo sagashite ita
Kitto nozomu kotae wa kono te no naka ni aru

Hajimari wo tadotte himotoita toki
Tozasareta kokoro ga tobitatsu( To the sky)

I believe. . .
Sora no hate ni kuruoshiku tsuzuku
Yami wo nuguisaru hikari tsukamu made wa
I decide. . .
Dare ka ja nai hatasubeki mono wa
Kitto donna toki da tte“ watakushi” da kara

For you owarasetakute kizukanu furi wo shita
For me meguru deai ga shimei wo yobisamasu

Hodoketa omoide wo hito-tsu musube ba
Donna ni hanarete mo mayowanai( fly to you)

I believe. . .
Suterarenai taisetsu na hibi ga
Itsu mo chīsana watakushi wo ugokashite iru
I decide. . .
Hashiridase ba kumo sae mienai
Ima wo ryōte ni kakagete tsukinuketai

Watakushi wo tsukuru kako to mirai wa
Itsu da tte subete wo
Tsuyoku dakishimeru

I believe. . .
Sora no hate ni kuruoshiku tsuzuku
Yami wo nuguisaru hikari tsukamu made wa
I decide. . .
Dare ka ja nai hatasubeki mono wa
Kitto donna toki da tte“ watakushi” da kara
“ watakushi” da kara
