|eng1=
My magic, and everyone’s voices –
I pray that, somehow, they can resound even more strongly.
|eng2=
Even if our ways of existing are different,
I won’t be lonely,
So I pray that, somehow, I can always be by your side
Continuing to sing.
|eng3=
I prayed that, someday,
We could play our first etude together
Just like this.
I want to convey it…
|eng4=
‘Calmly, with expression.’
‘Agitated, with force.’
And sometimes,
‘With love.’
|eng5=
If everyone will be by my side,
Then I won’t be lonely.
So I pray that, somehow, I can always be by your side
Continuing to perform.
|eng6=
I prayed that, someday,
We could play our first etude together
Just like this,
So resound! More and more!
|eng7=
I pray that I will always be by your side,
And that I can continue to perform.
I make all our voices become one,
So they will not disappear.
|eng8=
I prayed that, someday,
We could play our first etude together
Just like this.
That’s what I wanted to tell you…
