Lyrics
Aitaku nattara yozora ni yonde mite
Itsu demo yume de modotte kuru kara ne
Omoide ippai niji-iro shabondama
Sabishii kimochi wa onaji sa onaji sa boku datte
BAI BAI BAIYON hanarete ite mo
BAI BAI BAIYON kokoro wa hitotsu...
Nakazu ni nakazu ni me to me de chikai
Mata au toki made niji-iro no BAIYON
Hajimete futari ga deatta machikado wa
Higure no niji ga dete ita ame agari
Karameta koyubi ni yasashiku KISU shitara
Matsuge ni kirari to hikatta hikatta nagareboshi
BAI BAI BAIYON ano hi no koto wo
BAI BAI BAIYON wasure wa shinai...
Anata ni anata ni shiawase mitsuke
Kaette kuru kara niji-iro no BAIYON
Wasure wa shinai yo donnani tooku te mo
Kanpai shiyou yo mouichido futari kiri
Anata to boku to wo musunda niji no hashi
Hana saku kisetsu ni tsudzuku yo tsudzuku yo eien ni
BAI BAI BAIYON hanarete ite mo
BAI BAI BAIYON kokoro wa hitotsu...
Egao de egao de ashita wo chikai
Mata au toki made niji-iro no BAIYON
BAI BAI BAIYON ano hi no koto wo
BAI BAI BAIYON wasure wa shinai...
Anata ni anata ni shiawase mitsuke
Kaette kuru kara niji-iro no BAIYON
