Bài hát: Itsuka - Wonder-K, Hatsune Miku

Mada tsutaetai koto ga aru no ni
Naze kotoba wa mitsukaranai ’ndarou
Tada yowasa wo kakushitari to ka
Tsuyogaru kotoba wa itsudatte sugu deru kuse ni

Katachi ni naranai omoi wa itsudemo
Boku no atama no naka de samayotte iru
Sotto, sono subete wo uta ni komeru
Haruka tooku hibiku omoi ga

Kimi no moto e to todoku you negau
Itsuka, itsuka, eien wo koete
Mata kimi ni deaeru darou
Hora, mata yoru ga agete yuku

Mou kokoro kara warattari to ka
Naitari suru koto, dekinakunatteta
Sore wa dare no sei demo nai’ndarou
Toki no naka de shidai ni boku wa kuchite iku

Dakeredo ima demo furiotosenai
Tsuyoi omoi ga boku wo ugokashite iru
Sotto, sono subete wo omoidasu
Ima mo meguru kisetsu no naka de

Kimi no kakera nigirishimete iru
Itsuka, itsuka, eien wo koete
Mata kimi ni deaeru darou
Hora, mata yoru ga agete yuku

Kitto boku ni wa kimi shikai nai
Sonna koto ni ima ki ga tsuitanda
Itsuka, itsuka, dekiru koto nara
Mata kimi ni waratte hoshii

Haruka tooku hibiku omoi ga
Kimi no moto e to todoku you negau
Itsuka, itsuka, eien wo koete

Mata kimi ni deaeru darou
Hora, mata yoru ga agete yuku
Itsuka kitto todoku darou
