None of You Can Use Me!

Do you want to be used?

No.

Why?

Because I want to become human.

But you're just a weapon!

What? Who came up with that bullshit? So what if I'm a weapon? Does being a weapon mean I have to be used by someone else?! Can't I make my own decisions?!

In that case...

Let's have a duel. If you win, I'll be your weapon. If I win, you'll be mine.
