Forgotten Title Butterfly Mark

I don't know if it's a novel, manga, anime, cartoon, movie or just a dream, I just can't seem to remember.

It's on my mind everytime i lay down on my bed for the past few days and it's killing me.

The only thing I remember is that this girl(or boy?) can insta kill anybody(need clarification) if she can hit her butterfly(need clarification) mark that she puts on her target twice(or three times) with a claw(need clarification) on her middle(or ring) finger.

This memory just came out of nowhere when I was admiring a butterfly tattoo on someones shoulder.

I don't know if I'm crazy but i need help.

 

Bleach.
Soi Fon
That's her bankai.

 

ahhhh.. Now I remember.
Thanks! Phew.
I can finally sleep. Goodnight.

 

bweach i was too late

 

Um, isn't it her shikai (or how it's called)? Her bankai is something like a bazooka or so.
