Les paroles de la chanson
« Once upon a me (mukashi mukashi no kyou no boku) »
Miku Hatsune

Chotto dake otsukiai negaimasu
Chotto dake ushiromuki na kono uta
Kagami ni utsuru kinou no boku wa
Kyou no boku ni totemo yoku niteite

Kanashikatta kuyashikatta tsurakatta yo
Demo dare mo kiite kurenai kara
Kono hiza kozou ga boku no otomodachi

Poroporo to ochiru namida ga
Dokka no darekasan ni todoita
"Nee shitteru kai?
Kokoro tte kimi igai no hito ni shika mienainda yo"

Ima, boku wa mukau ashita he to
Ryoute wo futte "mata ashita ne" to
Sono senaka me ga ke "ganbare" to
Kiita koto aru koe ga kikoeta yo
Douji ni kakedasu asufaruto (asphalte)
Shimikomu attakai namida
Dakara bye bye
"Mukashi mukashi no kyou no boku"

Hikitsuzuki otsukiai negaimasu
Chotto dake maemuita kono boku no
Kokoro wa pikapika hikatte mieteru ka na

Kanashikatta? Kuyashikatta? Tsurakatta ne
Demo dare mo kiite kurenai toka iwanai de ne
Boku no otomodachi

Poroporo to ochiru namida ga
Kyou no boku no mimi ni todoita yo
"Hora, daijoubu!
Kimi no kokoro wa chanto boku ga miteru kara"

Ima, kimi wa mukau ashita he to
Ryoute wo futte "mata ashita ne" to
Sono senaka me ga ke "ganbare" to
Kiita koto aru koe de sakenda yo
Douji ni kakedasu
Pikapika to hikaru kokoro wo nosete
Dakara bye bye
"Mukashi mukashi no kyou no boku"

Ato chotto otsukiai negaimasu
Chotto dake naki sou na kono boku wo
Sasaete kureta minna no koto wo
Kondo wa boku ga ouensurunda

Kanashikatta kuyashikatta tsurakatta yo
Demo chanto kimi ga mite kureta yo
Kiite kureta yo
Kondo wa boku no ban

Poroporo to ochiru namida ga
Tsukutta umi de oyogezu ni mogaiteru kimi ni
Tonaeru yo mahou no jumon
"Daijoubu" toiu kokoro no ukiwa

Ima, kimi to mukau ashita he to
Sono te wo tsunai de ashita he to
Kono senaka de dakishimete kita
Takusan no koe wo kiki nagara
Douji ni nakidasu kimi to boku
Miseau attakai egao
Dakara bye bye
"Mukashi mukashi no kyou no boku"
