Kokoro

A robot created by a lonely scientist
If I were to describe its appearance, it's a "miracle"

But there's still one thing missing
It's a program called "heart"

Hundreds of years have passed
Left alone
The miraculous robot wishes

The person I want to know
Until the end of life
Was creating
A heart for me

Now the accelerating miracle starts moving
For some reason, tears won't stop
Why am I trembling? Accelerating heartbeat
This is the "heart" I desired

Mysterious heart, mysterious heart
I have learned what brings joy
Mysterious heart, mysterious heart
I have learned what brings sadness
Mysterious heart, mysterious heart
Why is it so deeply painful

Now I'm beginning to realize the reason for my birth
Surely, being alone is lonely
Yes, on that day, at that time
The "heart" residing in all memories overflows

The true words I can say now
I offer to you
Thank you for bringing me into this world
Thank you for the days we spent together
Thank you for everything you gave me
Thank you, I will sing forever
