Kokoro ga hajikete tonda nande darou?
Hashitte minakucha wakaranai
Uzukumatta mama no fuan tobikoe
Te o tsunagi kimi to kaze ni naru

Mizutama moyou mitai na shiroi kumo
Mitsukete waratta (miagete waratta)
Mune ga takanatta (kyuu ni takanatta)
Hajimari no oto ga suru

(Ima da! Dekakeyou)
Sora ni yubisaki de ko o egaku no sa
Ukabi agaru yo Dream Rainbow
Me de miru dake ja mou tarinai yo
Kirameki o tasou jiyuu ni

(Kimi ni deaeta)
Koe o kasaneru tabi ni kanjiteru
Mugen ni fukuramu tokimeki
Ikeru yo datte kimi ga issho dakara
Tatoeba sou yozora ni mo niji ga kakaru

Totsuzen aitaku natta nande darou?
Tobira o akenakya wakaranai
Fuwafuwa umareru ironna kimochi
Shabon mitai natsukashii nioi

Tsutaetai koto itsudemo nomikonde
Umaku ienakatta yo (kimi ga kaeta no)
Ima wa ieru nda (minna ierunda)
Tsuyoku narerunda (motto narerunda)
Hajimari no oto mune ni hibiku yo

Hitori bocchi janai yo egakou yo
Dakishimete ita Dream Rainbow
Me de miru dake ja mou tarinai yo
Kirameki o tasou jiyuu ni

(Kimi ni deaeta)
Koe o kasaneru tabi ni kanjiteru
Mirai o shinjiru tokimeki
Ikeru yo datte kimi ga issho dakara
Niji ga hora oozora ni hirogatte yuku

心がはじけて飛んだ　なんでだろう？
走ってみなくちゃ分からない
うずくまったままの不安とびこえ
手をつなぎ　君と風になる

水玉模様みたいな白い雲
見つけて笑った（見上げて笑った）
胸が高鳴った（急に高鳴った）
はじまりの音がする

（いまだ！出かけよう）
空に指先で弧を描くのさ
浮かびあがるよ　Dream Rainbow
目で見るだけじゃもう足りないよ
きらめきを足そう　自由に

（君に出会えた）
声を重ねるたびに感じてる
無限にふくらむときめき
行けるよ　だって君がいっしょだから
たとえばそう　夜空にも虹が架かる

突然会いたくなった　なんでだろう？
扉をあけなきゃ分からない
ふわふわ生まれる色んなキモチ
シャボンみたい　なつかしい匂い

伝えたいこといつでも飲みこんで
うまく言えなかったよ（君が変えたの）
いまは言えるんだ（みんな言えるんだ）
強くなれるんだ（もっとなれるんだ）
はじまりの音　胸に響くよ

ひとりぼっちじゃないよ　描こうよ
抱きしめていた　Dream Rainbow
目で見るだけじゃもう足りないよ
きらめきを足そう　自由に

（君に出会えた）
声を重ねるたびに感じてる
未来を信じるときめき
行けるよ　だって君がいっしょだから
虹がほら　大空に広がってゆく
ララララララ

Why did my heart burst and fly away?
I'll never know unless I run to the answer
I'm still cowering, jumping over my fears
I shall hold your hands and become the wind

The white clouds are like polka dots
I looked up and laughed at them (looked up and laughed)
My heart was pounding (suddenly pounding)
I can't hear the sound of the beginning

(Now's the time! Let's go out)
I'm drawing arcs in the sky with my fingertips
The dream rainbow will come to life
Seeing it with my eyes isn't enough anymore
So, let's continue shining until the end of time

(I met you)
I feel it every time I harmonize with you
My excitement will last forever
I can go because you're with me
For example, yes, there's a rainbow in the night sky

Suddenly, I miss you. I wonder why?
I won't know until I open the door
Various feelings are born in a fluffy way
Like soap bubbles, the smell of my childhood

Swallow what you want to say
I couldn't say it well (you changed it)
Now, I can say it (everyone can say it)
I can be stronger (even stronger)
The sound of the beginning is echoing in my chest

I'm not alone, let's paint it
The dream rainbow I've been holding on to
Seeing it with my eyes isn't enough anymore
So, let's continue shining until the end of time

(I met you)
I feel it every time I harmonize with you
The excitement we believe awaits us in the future
I can go because you're with me
Rainbows are spreading across the sky
La, la, la, la, la, la!
