Boku ga tsukutta "zukan" no naka nante
Kitto mama ni wa wakannai darou
Chitchana koro kara tameteta misuterii wa
Kirakira hikatte mada mitsukannai ne

Mukashi kara fushigi datta
"Uchuu no deguchi wa aru no ka na?"
Sora no deguchi wo dereba mugen ni hirogatte

Sora no sora ni wa saki wa doko made arun daro?
Mada daremo uchuu no saki nante
I've not seen!! Mitenai!!!

Papa no motteru zukan no naka nante
Kitto monokuro tsumannai daro!
Chitchana tenohira nokkaru misuterii wa
Giragira togatte ugokidashita!

Uchuu no makkura ni kakomare aoku ukabu hoshi hitotsu
Jimen ichimai de hito wa mugen ni tsunagatte

Ao no sora demo ironna nayami kakaete ne
Daremo ga ao no shita waratteru
I wanna look!! Mitetai!!!

Miru koto dekinai no ni susumitaku naru no wa
Susumanakya mirenai mirai yume issho datta

Warae warae hazumu kimochi warae
Naite motto ashita wa waratte
Yureru yureru ki to tomo ni hashaide
Our precious the earth!!

Sora no sora ni wa saki wa doko made arun daro?
Mada daremo uchuu no saki nante
I've not seen!!

Ao no sora demo ironna nayami kakaete ne
Daremo ga ao no shita waratteru
I wanna look!! Mitetai!!!
