[ Romaji ]
Niji o mezashite aruiteru n da to bi-dama mitai ni
Waratte ita waratte ita kara
Omoitsuku mono hashi kara jun ni
Furui ryukku ni tsumekonde kita
Dokomademo iko toku toku e
Niji no fumoto ni te o tsuku made
Mita koto nai mono o futari de miyo
Itsuka juji-ro de te o furu made
Chizu wa nigate to potsuri koboshite fukkireta yo ni
Hashitte iku hashitte iku kara
Mitekita zenbu otosanai yo ni
Furui ryukku ni oshikondoita
Dokoni mo nai mono hitotsu hitotsu
Hiroiagete kita takaramono
Ichido kiri desho futari de miyo
Itsuka niji no shita te o furu made
Cho no koe inazuma no kakera
Kumo no aji aozora no kaori
Takusan no mono to ashiato no kazu deatta yo
Dokomademo iko toku toku e
Niji no fumoto ni te o tsuku made
Mita koto nai mono o futari de miyo
Itsuka juji-ro de te o furu made
Itsuka niji no shita te o furu made
