[HOOK]
Oh, my sister
Nothing can come between us
Sometimes we fight, but always make it right
Oh, my sister
You're my best friend and soldier
For you I'd give my life

Black bird いつも自由に飛びまわる my little sister
人一倍幸せになりたくて struggle with everything
Oh, my sister そんな君をいつも見守ってるよ
Keep flying never don't stop
And keep rising to the top, together

[HOOK]

Oh, my sister
Nothing can come between us
Sometimes we fight, but always make it right
Oh, my sister
You're my best friend and soldier
For you I'd give my life

We are blood sisters
この体内に流れる
真赤な血、細胞うめつくす兄弟の証
照りつける太陽も
草木しげる地上も
砂城と化す
波うちぎわの岩より固い絆
打たれてもかけない
この魂は Hard as rock
When your life is hard for you
I will always be there for you

We will stay here forever, We sing this song together
Cause you are my sister

[HOOK]

More than words
大切な何かを見つけるため
手さぐりで歩いてる this is how we are
Oh, my sister
飛び立つ いつか その時のために
We sing forever
We sing forever

I promise, protect you
Cause you are my sister
Whenever you need, you can call on me
Cause you are my sister
Cause you are my sister baby

[HOOK]
