Kodoku na kagakusha ni tsukurareta robotto
Dekibae o iu nara "kiseki"

Dakedo mada tarinai hitotsu dake dekinai
Sore wa "kokoro" to iu puroguramu

Ikuhyaku toshi ga sugi
Hitori de nokosareta
Kiseki no robotto wa negau

Shiritai ano hito ga
Inochi no owari made
Watashi ni tsukutteta
"Kokoro"

Ima ugoki hajimeta kasoku suru kiseki
Nazeka namida ga tomaranai...
Naze watashi furueru ? Kasoku suru kodou
Kore ga watashi no nozonda "kokoro" ?

Fushigi kokoro kokoro fushigi
Watashi wa shitta yorokobu koto o
Fushigi kokoro kokoro fushigi
Watashi wa shitta kanashii koto o
Fushigi kokoro kokoro mugen
Nande fukaku setsunai... ?

Ima kidzuki hajimeta umareta riyuu o
Kitto hitori wa sabishii
Sou, ano hi, ano toki
Subete no kioku ni yadoru "kokoro" ga afuredasu

Ima ieru hontou no kotoba
Sasageru anata ni

Arigatou... Kono yo ni watashi o unde kurete
Arigatou... Isshoni sugoseta hibi o
Arigatou... Anata ga watashi ni kureta subete
Arigatou... Eien ni utau
