Kodoku na kagaku-sha ni tsuku-rareta robot
Dekibae wo iu nara,

"Kiseki"...

Dakedo mada tari-nai hitotsu dake deki-nai
Sore wa "KOKORO" to yuu program...

Iku-hyaku toshi ga sugi
Hitori de noko-sareta
Kiseki no Robot wa negau...

Shiri-tai ano-hito ga
Inochi no owari made
Watashi ni tsukutteta

"Kokoro"...

Ima ugoki hajimeta kasoku suru kiseki
Nazeka namida ga tomara-nai...
Naze watashi furueru? kasoku suru kodou
Kore ga watashi no nozonda... "KOKORO" ?

Fushigi KOKORO KOKORO Fushigi
Watashi wa sitta yorokobu koto wo
Fushigi KOKORO KOKORO Fushigi
Watashi wa sitta kanashimu koto wo
Fushigi KOKORO KOKORO Mugen
Nante fukaku setsu-nai ah...

Ima kizuki hajime-ta umareta riyuu wo
Kitto hitori wa samishii...
Sou, ano-hi ano-toki
Subete no kioku ni yadoru KOKORO ga afure-dasu
Ima ieru hontou no kotoba
Sasage-ru anata ni

ARI-GA-TO, ARI-GA-TO... kono-yo ni watashi wo unde kurete
ARI-GA-TO, ARI-GA-TO... issho ni sugose-ta hibi wo
ARI-GA-TO, ARI-GA-TO... anata ga watashi ni kureta subete
ARI-GA-TO, ARI-GA-TO... eien ni utau
