Lời bài hát Niji
Naite iindayo sonna hitokoto ni
Boku wa sukuwaretandayo
Hontouni arigatou
Nasake naikeredo darashi naikeredo
Kimi wo omou koto dake de
Ashita ga kagayaku
Arinomama no futari de iiyo
Hida mari mitsukete asobouyo
Beranda de mizu wo yaru kimi no
Ashimoto ni chiisana niji ne
Isshou soba ni irukara
Isshou soba ni ite
Isshou hanarenai you
Ni isshou kenmei ni
Kitsuku musunda me
Ga hodokenai you ni
Kataku tsunaida te wo hanasanaikara
Mama no yasashi sa
To papa no nakimushi wa
Marude bokura no
Youdesa mirai ga itoshii
Oukina yume janakute iiyo
Jibunrashi kuiraretara iiyo
Hitori bocchi mayotta toki wa
Ano koro wo omoidashite ah
Sabishii yoru wo hanbun
Boku ni azukete hoshii
Ureshii hibi wa juubun ni waraiatteitai
Donna kotoba demo tarinai youna
Kimi no nukumori ni fureta sei kana
Kazoku ya tomodachi no
Koto konna boku no koto
Itsumo daiji ni waraukara
Nakete kurundayo
Nani mo nakatta sora ni
Potsun to kagayaiteita
Arigatou ni kawaru
Kotoba zutto sagashiteitanda
Isshou soba ni irukara
Isshou soba ni ite
Isshou hanarenai you
Ni isshou kenmei ni
Kitsuku musunda me
Ga hodokenai you ni
Kataku tsunaida te wo
Hanasanaikara
Hanasanai kara
