Letra da Música Utakata de Heidi.

Aa, kono subarashiki sekai ga
Boku wa shinsoko kirai na n'da
Aa, kono toki wo ajiwau nara
Boku ga iru imi tte nan desu ka?

Moshimo boku no koe ga todoite iru nara
Boku no koe wo kiite kureteru nara
Tada hitotsu tsutaetai koto ga aru
Dakara kanashii koto nante iwanaide
Daremo ga nozonde iru shiawase wo
Kegasareta yoku hareta hiruma no you sa

Hito wa naze utsukushii no deshou? Naze minikui no deshou?
Kokoro niyadoru mono wa
Itsu ka sou sono kotae no naka ima boku ga ikiru koto
Uketomete mimasu.

Aa, kono subarashiki sekai ni
Boku wa subete wo sasagete iru
Aa, hakanaku chitte iku nara
Umarete shimatta koto wo iwaou

Boku wa gensou ni oboreta orokamono
Saisho kara wakatteta hazu na noni
Itsu no hi mo kokoro wa obiete ita
Katakuna ni chikatta ano toki no yume wo
Sutesaru koto e no tamerai sae mo
Nokoranai boku wa ikiteru to ieru no?

Hito wa naze kagayaku no deshou? Naze ushinau no deshou?
Tsuka no ma no isshun wo
Dakara ima kono kagiri no aru yorokobu beki kibou wo
Uketomemashou ka
