Sha la la... itsuka kitto
Boku wa te ni surunda
Hakanaki mune ni sotto
Hikari moete yuke

Aitaku naru no shoutou
Naki taku naru no junjou
Natsu no hi ni tobi konda
Hotaru wa kae ra nai

Anata wa nani mo iwazu
Kuchizuke wo nokoshite
Kizutsu ku mama una zui nare
Kanashii hodo inochi yurameite ita

Sha la la... itsuka kitto
Boku wa te ni surunda
Hakanaki mune ni sotto
Hikari moete yuke

Sha la la... itoshiki hito
Anata mo miete iru no
Mabayui tsuki ga sotto
Ashita wo tera shite

Tsuyoku tsuyoku... kagayaite

Kaze ni fukare ni hodo
Hageshiku naru kokoroni
Hagure sou na omoide ga

Matayasa shiku komoru
Muchuyude kake da shitara
Uemareru kiga shita
Omoru ku nama
Teo nabasuyo
Setsunai hodo inochi yurameite yuku

Sha la la... boku wa zutto
Utai tsuzu keteikuyo
Furueru mune ni sotto
Hikari moete yuke

Sha la la... itoshi ki hito
Anatani todokume you ni
Hakenai sora ni sotto
Omoi tsugora sete

Tsuyoku tsuyoku... hibikasete

Sha la la itsuka kitto
Hotaru wa moetsuki
Chite kieyuku
Mune ni soto
Yume o kagayaite

Sha la la... itoshiki hito
Anata mo wasurenai de
Kimareku natsu ni sotto
Negai wo kesagete

Sha la la... itsuka kitto
Boku wa te ni surunda
Hakanaki mune ni sotto
Hikari moete yuke

Sha la la... itoshiki hito
Anata mo miete iru no
Mabayui tsuki ga sotto
Ashita wo tera shite

Tsuyoku tsuyoku... kagayaite
