Nana-iro no REINBOO tomodachi tsurete mi ni yukou
Nana-iro no REINBOO sakki kenka shita tomodachi mo
Tomodachi nannin dekita kana
Nankai attara tomodachi ka
Nante sora wo mite kangaeta
Tooku no kumo ga waratta
Warau soba de tori-tachi uta wo kanadetara
Hirori futari san, yo, gonin
Atsumaru kara
Dare ni mo osowaranai tomodachi no tsukurikata
Yuuki genki yaruki te wo furi manabi
Nana-iro no REINBOO sorezore no michi sorezore no iro
Nana-iro no REINBOO ikusaki onajite wo tsunagi
Aka ORENJI ki-iro midori ao ai-iro murasaki
Kyou no kimi donna iro?
Minna to kimi no iro shinjite GO!
Ano kumonoue ni noreru kana
Onaka ga hettara tabeyou kana
Nante sora wo mite kangaeta
Tonari no taiyou waratta
Warau shita de boku-tachi uta wo kanadetara
Rokunin nananin hachi, kyuu, juunin
Waraeru kara
Dare ni mo osowaranai kokoro no tsutae kata
Yuuki genki yaruki te wo furi utai
Nana-iro no REINBOO sorezore no michi sorezore no iro
Nana-iro no REINBOO ikusaki onajite wo tsunagi
Aka ORENJI ki-iro midori ao ai-iro murasaki
Kyou no kimi donna iro?
Minna to kimi no iro shinjite GO!
Nana-iro no REINBOO sorezore no michi sorezore no iro
Nana-iro no REINBOO ikusaki onaji te wo tsunagi
Nana-iro no REINBOO sorezore no michi sorezore no iro
Nana-iro no REINBOO ikusaki onajite wo tsunagi
Aka ORENJI ki-iro midori ao ai-iro murasaki
Kyou no kimi donna iro?
Minna to kimi no iro shinjite GO!
