Kuchibiru sugite 'ku kotoba-tachi yori mo
Tashika na mono ga aru no sa
Shizuka ni moete 'ru itsutsu no omoi wa
Toki ga mei sureba hikari ni kawaru

*Don't forget the promise
Ai ni sarawarete mo
Don't forget the promise
Hitomi fusagarezu ni
Wasurezu ni ite kure Ano hi no chikai wo
Kakegae no nai aoi houseki wa
Ima kimi-tachi ni yudanerareta
Blue Blue Blue Togetherness

Mayoi wa yowasa no sei de wa nakute
Yasashii haato no baransu sa
Mabayui hitotsu wo oikakete mite mo
Nobara no hakanasa wo ai shite hoshii
Don't forget the promise
Yume wo sasuratte mo
Don't forget the promise
Yami ni tsubusarezu ni
Te hanasazu ite kure yakusoku no kagi wo
Uchuu no inori aoi houseki wa
Ima kimi-tachi ni yudanerareta
Blue Blue Blue Togetherness
