Letra de Niji
Kiyasume gurai ni nareba ii yo
michi ni mayotte hikikaeshite
jikan dake sugite yuku kedo

Tsumikasaneta omoide toka
oto wo tatete kuzuretatte
bokura wa mata kyou wo kioku ni kaete ikeru

Usui koori wo waranai you ni
shita wo muite aruku boku wa
kantan ni niji wo miotoshita

Mayowazu ni sumu michi mo atta
dokonidemo ikeru jiyuu wo
ushinau hou ga motto kowakatta

Tsumikasaneta omoide toka
oto wo tatete kuzuretatte
bokura wa mata kyou wo kioku ni kaete ikeru
machigai toka sure chigai ga
bokura wo kirihanashitatte
bokura wa mata kyou wo kioku ni kaete ikeru

Tachidomatte miageta sora ni
kotoshi hatsu no hoshi ga nagareru
nantonaku kore de ii to omotta

Tsumikasaneta omoide toka
oto wo tatete kuzuretatte
bokura wa mata kyou wo kioku ni kaete ikeru
machigai toka sure chigai ga
bokura wo kirihanashitatte
bokura wa mata kyou wo kioku ni kaete ikeru
