Letra de World is mine: kagamine len (en ingles)

The number one princess in the whole entire world
I know by heart how to treat you like that
Don´t I?

First, I notice that your hairstyle is different from usual
Second, I should bow down really low whenever I meet you
So sorry!
Third, I will go along with every selfish desire you ask for with a pretty concise response
I understand, so forgive me now for taking your hand
I really don´t think you´re selfish
But I do think you´re pretty cute.
I just don´t like saying it in front of you!

The number one princess in the whole entire world
I promise I´ll be by your side forever
So keep smiling
And if you ask me, we´re one when we´re together
I´ll never leave you, princess
I love you!

Check 1, 2
Aaa!

A fault? She has countless!
I´ve never had a day where she says nothing
And she never really listens to her brother, ya know?

Well, but, yeah
That innocent smile and the sweet voice that calls my name
I don´t hate that.
Oh shut up... I´d never say that.
After all, you´re the princess.
I really don´t think you´re selfish,
But can´t you lend me a hand sometimes?

My number one princess in the whole entire world
You´re more precious to me than anybody else
I´ll be the one to hold your hand.
Aren´t you satisfied with me?
I didn´t mean that!
I was just joking! Seriously!
WA!
You really don´t understand!
I was truly just joking

Remember the first song we sang together?
OK. "Green is the enemy, right?"
Nothing, nothing. I´ll never forget anything
Those are the memories with my princess
"Don´t tell me you remembered?"
"You remembered it too."
Of course I remembered.
Because you are...

The number one princess in the whole entire world
I´ll keep watching you, so stay as you are.
Suddenly, I reached out with my right hand and squeezed.
"I just wanted to hold it, that´s all."
And when she presses back...
My princess is certainly the best!
