"Kokoro"

A lonely scientist developed a robot
The result was said to be a "miracle"

But it wasn't yet sufficient; there was just one thing he wasn't able to do
And that was the program known as a "heart"

Hundreds of years pass
Left alone
The miracle robot wishes

I want to know, why
Until the end of that person's life
He built a "heart"
For me

Now, movement has started, the miracle is accelerating
Why? My tears don't stop...
Why am I shaking? The beat is accelerating
This is the "heart" I hoped for?

Mysterious, heart, heart, mysterious
I know; there are things to be happy about
Mysterious, heart, heart, mysterious
I know; there are things to grieve about
Mysterious, heart, heart, infinite
How deeply painful...

Now, I've begun to realise the reason I was born
Being on your own is surely lonely
Yes, that day, at that time
All the memories dwelling in my "heart" begin to overflow

Now, I can speak true words
I dedicate them to you

Thank you... for bringing me into this world
Thank you... for the days we spent together
Thank you... for everything you have given me
Thank you... I will sing for eternity
