Lyrics for Sunao na Niji from Naruto: Shippuuden by Surface (Ending #5)
Kodomo no koro mita niji wo ima miageru to
Nanairo de wa naku yagate kiri ga kakari
Jikan wa sugi kawatte yuku kimi wo sagashite mo doko ni mo inai

Me wo toji kokoro hiraite mata nagamete mite mo
Nani mo kawara nai no ka tashikamete mitai

Sunao ni narereba kono kiri ga hareru to kokoro ni negai sou sakenderu
Nani ka wo nakushite shimatta koto de
Sou te ni shita mono mo kitto arun darou
Dakedo mada bokura wa otona ni tomadoi ikite yuku sube sagashiteru

Ame ga yamu to fuini kimi ha hodoukyou ni nobori
Sora wo yubisashite mujaki ni waratteta
Kieiru you na suketa niji wo nani mo ie nai mama nagamate itane

Hountou wa ano toki zutto
Kimi no yokogao wo miru koto ni muchuu ni natteta wasure nai tame ni

Sunao ni narezu ni tada kimi no namae wo kokoro no naka de sou sakenderu
Kimi wo ushinatte made te ni shitai mono nado nai hazu na no ni dou shite darou
Nureta kami wo dzutai ochiru no wa sayonara to iu namida datte ne

Ameagari wa ima mo hodoukyou kara semai sora miage kakehashi wo sagasu kedo
Kimi no moto he tadoritsuke nainda MONOKURO no sekai ni iru

Kotoba ni dekizu ni tojikometa omoi wo ima sara kimi ni toikakete miru
Yowasa no sei ni shite nigedashita no wa
Sou kimi no hou ja nai boku no hou da yo

Sunao ni narereba kono kiri ga hareru to kokoro ni negai sou sakenderu
Nanika tarinakute mo ima aru iro de sou boku no sekai wo nurikaete mitai
Itsuka mata kimi ni aeru nara sunao ni omoi tsutaeru kara
Sunao na niji wo egaite miru kara

If I look up now for the rainbow I saw as a boy,
There are no longer the seven colors.
Only mist and fog.
As time passed by and the world around me changes,
No matter where I search for you, you're nowhere to be found.
So I close my eyes and open my heart.
I need to know if I gaze up again,
Will things be different this time?

Maybe if I was honest, the fog would fade away
So I pray, screaming that wish deep within my heart.
When you lose one thing,
You gain another, don't you?
But still no matter how often the adults confuse us,
We'll keep looking for the right way to live our lives.

When the rain stopped, you walked to a bridge,
Pointed to the sky, and smiled innocently.
Nothing was able to be said,
when looking at the vanishing rainbow.
That time, I really watched you for a long time,
and I can't forget it.

I am not used to being gentle,
so I simply shout your name in my heart.
There is nothing I want to obtain
from losing you.
The tears of goodbye are
dripping like wet hair.
I still look up at the small sky from a bridge every time the rain stops,
Searching for you.
I am in a monochromatic world
Where I cannot reach you.

I ask you about the thoughts,
That I shut in for a long time.
You blame your faults on your weakness and run away.
That is not better for you, but for me

Maybe if I was more honest, the fog would fade away.
So I pray, screaming that wish deep within my heart.
I want to repaint my world with some color.
Even if there is not enough now,
I tell myself to think gently.
If I can meet you again sometime,
I draw a gentle rainbow.
