“Kokoro”
Words/Lyrics: Toraboruta 

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 fushigi
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

“Heart” 

A robot was built by a lonely scientist,
When his work was done, it was known as a “miracle” 

But something was missing, there was one thing he couldn’t do,
and that was the program called a “heart”

Many years passed, 

and the miracle robot that had been left all alone,
made a single wish:

Give me the “heart”, that that person,

The person I’ve always wanted to know,
made for me, until the very end of his life.

Now that that miracle has started to occur,
Why, why won’t my tears stop flowing….? 

Why am I shaking? What are these beats inside me?
Is this the “heart” that I wished for?

Mysterious heart, mysterious feelings,
All the joys I had come to know,
Mysterious heart, mysterious feelings,
All the depressing things I had come to know, 

Mysterious heart, mysterious feelings,
They all seem so deeply painful…

Now I’m beginning to understand the reason I was born,
Being alone must truly be depressing, 

Yes, on that day, at that time,
All the feelings that had dwelled in my memories flowed out of my heart. 

But now, I can say these words for real,
to you, my creator, who dedicated his life to me, 

Thank you… for bringing me into this world.
Thank you… for the days you spent with me.
Thank you… for everything you’ve given me
Thank you… I will sing for eternity.
