Kikyuu ga niji wo koeta hi

Me wo hosomete nozoite goran
"Nani ga mieru?"
Kumo to kumo no aida kara
Niji no yokan
Kimi wa itta
"Hito wa sora wo mo toberunda"
Itsuwari nai massugu na
Omoi ni tsukamatta

Terasu yo mabushii hikari
Deguchi wa mie nai
Mi nai hou ga ii

Ikura toki ga nagarete mo
Kawara nai kotae ga aru
Chiisa na kado kara
Kiritoru ooki na sekai he
Sora uku kanata he KURURI
Oki wasureta mama no ao
Ima mo mukashi mo koko ni aru

Miru mono subete
Suikonde mitai
Kikyuu ga niji wo koeta hi

Kowagarazu ni nozoite goran
Sugu soko ni
Zutto egaiteta kodomo no goro kara
Kami hikouki
Tobashita totan
Ochita itta
Awai sora no iro subarashiku hibi
RARABAI

Shinkokyuu shite mita toki
Doko ka no fune ga sukoshi susunda

Ima to ima no musubi me wo
Hodoite mata hajime you
Chiisa na karada ni
Afureta kirameku kokoro wo
Ooki na kaban wo seotte
Owara nai tabi sagasou
Kitto kotae wa kantan

Mitsuketa toki no yorokobi wo shiru
Kikyuu ga niji wo koeta hi

Kono saki toshi wo tottemo
Umaretate no kokoro de aru you ni

Ikura toki ga nagarete mo
Kawara nai kotae ga aru
Chiisa na kado kara
Kiritoru ooki na sekai he
Sora uku kanata he KURURI
Oki wasureta mama no ao
Ima mo mukashi mo koko ni aru
Miru mono subete
Suikonde mitai
Motto motto te wo nobashite
Haruka tooku no bokura ni BAI BAI
Kikyuu ga niji wo koeta hi
