She appeared tough but that's because she used a mask.

Beguiled the the dagger of revenge,
She turned into a stranger 
A stranger capable of stabbing them when her control loosened.

One time, she snapped.
She killed a man. Wide eyed, she stared.
How dreadful. Her eyes were glossy.
Hands tremblimg, she dropped her weapon.

Curling into a ball, she wept.
After all, she was still a girl.
A girl who is weak despite the front she displayed in front of everyone.
