Letra da Música Niji de Ikimono Gakari

Kasanariatta aozora ga bokura no yukute ni hirogaru
Okiku shinkokyushite yurunda kutsu no himowomusubu
Kawaru kawaru kono sekai no himitsu
O moichido mitsukeyou
Jibunrashiku yanda' tte taninrashiku nan'na tte
Tatoeba soko kara hajimaru mirai
Ga tashika ni aru to shite mo
Mada bokura futashikana michi no ue

Hashiridashita sekai ga boku o ashita e izanau
Nagarete iku keshiki wa yagate hikari to kawaru
Aru ga mama no negai o komete mata fumidaseba
Toku mieta sekai ga nanairo no niji e kawaru

Tsukareta nda' to nageku yori koko
Made kita' tte yorokobu
Son'nafuni omottetai son'nafuni ikiteitai
Yamanu koto nai kutsuoto
O mata ippoippo ashi shite ko
Sono hohaba wa itsu datte fuanteideattatte
Tojite wa hiraita mune no uchigawa ni
Fureyou to shite mitara
Dare mo mina uzuku yona kizu mo aru

Atarimae' no sekai ga boku ni kiseki o mi seru
Haruka mieru keshiki ga toku toku hirogaru
Iro toridori no ai ga boku o tsutsumikomukara
Yagate todoku mirai mo ikutsu mo no niji e tsudzuku

Tada hitotsuno sekai o bokurano iro ni someru
Togireru koto nai michi sono saki o mata mitsumeru
Hashiridashita sekai ga boku o asu e izanau
Nagarete iku keshiki wa yagate hikari to kawaru
Aru ga mama no negai o komete mata fumidaseba
Toku mieta sekai ga nanairo no niji e kawaru
