Lyrics
Saikou ni saitei na sonna toki mo
Zettai ni zetsumei na sonna hi demo
Ashita wa kyou yori takaku toberu sonna ki ga shita kara
Tada nansenkai demo ganbaru'n da
Itsumo SUMAIRU SUMAIRU!
Sou SUMAIRU SUMAIRU!
Kyou mo GUBBAI arigatou
Konai ashita nante nai
Dakara SUMAIRU SUMAIRU!
Zutto SUMAIRU SUMAIRU!
Shinpai wa iranai yo
Zenbu kitto umaku iku hazu sa
Are mo shitai kore mo shitai jikan taranai
Asette mo nageite mo PURASU mo nai
Dakara mae mite susumu shikanai ippo zutsu fumishime
Sou nanmankai demo tachimukau'n da
Misete SUMAIRU SUMAIRU!
Saa SUMAIRU SUMAIRU!
Kyou mo ippai yasashisa wo
Yamanai ame nante nai
Dakara SUMAIRU SUMAIRU!
Motto SUMAIRU SUMAIRU!
Mou naka nakute ii yo
Zenbu kitto umaku iku hazu sa
Kokoro ni te wo atete goran
Fukaku fukaku shinkokyuu shite
Yukkuri me wo tojite goran
Hiroi hiroi uchuu no naka
Jibun de tsukutta sekai tobidashite miyou
Hitomi wo akereba taiyou ga warau
Itsumo SUMAIRU SUMAIRU!
Sou SUMAIRU SUMAIRU!
Kyou mo GUBBAI arigatou
Konai ashita nante nai
Dakara SUMAIRU SUMAIRU!
Zutto SUMAIRU SUMAIRU!
Shinpai wa iranai yo
Zenbu kitto umaku iku hazu sa
