[Verse 1]
Itsumo sou yo
Nanika wo ushinatte kara
Taisetsu da to kidzuite kurande
Asu e fumidasu no wa kowakunatta
Kizu darake de
Kokoro no sora ame tsudzuki
Demo anata ga kureta hitokoto de
Sora ni niji ga kakaeta no
[Pre-Chorus]
Namida no bun dake
Asu wa motto yasashiku nareru
Mudana koto nante
Hitotsu mo nai kara daijoubu to
[Chorus]
Anata no yasashisa shitte
Umareta kimochi
"Arigatou, deaete yokatta"
"Sekai wa konna ni kagayaku
"Nijiiro shiteru"
Sou anata ga oshiete kureta
[Verse 2]
"Mou aenai"
Nante kangaeru dakede
Hitori bocchi sonna ki ga shiteta
Demo ima wa chanto wakaru
[Pre-Chorus]
Soba ni inakutemo
Moratta yasashisa wa, kiezu ni
Kokoro ni nokotte
Sasae tsudzukete kureru koto
[Chorus]
Kokoro no sora ni kakatta
Kono niji kitto
Asu ni tsunagaru kakehashi da ne
Anata ni hokoreru youna
Atashi sagashitе
Ima arukidasu to kimeta no
[Bridge]
"Tsumazuki sou ni nattemo
"Kokoro ni niji wo egakou"
Atashi mo itsuka darеka ni
Sono hikari wo tsutaetai no
[Instrumental Break]
[Chorus]
Anata no yasashisa shitte
Umareta kimochi
"Arigatou, deaete yokatta"
"Sekai wa konna ni kagayaku
"Nijiiro shiteru"
Anata ga oshiete kureta
Kokoro no sora ni kakatta
Kono niji kitto
Asu ni tsunagaru kakehashi da ne
Anata ga kureta yuuki wo
Kakae mezasu yo
Kagayaku niji no mukougawa
