新しい私になれ!
新しい私になれ!
小さな偏見を捨て
生まれ変わりたい

勇気をもっとください
勇気をもっとください
誰かの目線なんて
気にしたくない

新しい私になれ!
新しい私になれ!
ガンコな考えを捨て
生まれ変わりたい

勇気をもっとください
勇気をもっとください
本当の英雄として
生まれ変わるの　AH

atarashii watashi ni nare!
atarashii watashi ni nare!
GANKO na kangae wo sute

Be the new me!
Be the new me!
Throw away my little prejudice
I want to change myself
 
Give me more courage
Give me more courage
Don't want to care about the public eye 

Be the new me!
Be the new me!
Throw away my obstinate way of thinking
I want to change myself
 
Give me more courage
Give me more courage
As a real heroine
I will change myself  Ah
