Kasanariatta aozora ga bokura no yukutte ni hirogaru
Ookiku shinkokyuu shite yurun da kutsu no himo wo sugu
Kawaru kawaru kono sekai no himitsu wo mou ichido mitsuke yo
Jibun rashiku yandatte kani hirashiku nandatte

Tatoeba sokko kara hajimaru mirai ga
Tashikani aru to shite mo
Mada bokura hi katsukana michi no ue

Hashiri dashita sekai ga boku wo ashita e sasou
Nagarette yuku keshiki wa yagate hikari to kawaru
Aru ga mama no negai wo komette mata fumi daseba
Tooku ni etta sekka ii ga nana iro no niji e kawaru

Tsukaretta nda to na yaku yori koko made kida atte yorokobu
Sonna funi yo moo ttetai sonna funi kittetai
Yamanu koto nai itsu koto wo matta ippo ippo tashitte kyo
Sono ho haba wa itsu datte fuan te deatta tte

Tojitte wa ki warui tta mune no uchigau wa ni
Fure yo wo toshi tte mitara
Dare mo minna hikutsu yo na kitsumo aru

Atarima yoi sekai ga boku ni ki seki o miseru
Haru ga miaruge shiki ga tooku tooku hiro ga aru
Iro tori dori no ai ga boku wo tsutsu mikomu kara
Yagaatte to doku mirai mo ikutsumo no Niji e tsutsu ku

Tada hitotsu no sekai wo bokura no iro ni someru
Toginaru koto nai michi sono seki wo mata mitsu meru

Hashiri dashita sekai ga boku wo ashita e sasou
Nagarette yuku keshiki wa yagate hikari to kawaru
Aru ga mama no negai wo komette mata fumi daseba
Tooku ni etta sekka ii ga nanairo no Niji e kawaru
