With both hands in the shape of a sword -- at this super close distance, she gets ready to fight.

I imitate her.

In this case a handchop is better than forming a fist.

With the arm power of a vampire, both fists’ and handchops’ power could be said to be within the margin of error. In that case, it is easier to use a handchop that is more flexible--

My handchop struck Kissshot's face in a horizontal swing -- the upper half of her head was severed, and it was blown behind together with her golden hair.

Like she was waiting for it, Kissshot's handchop blew up my head. Although it was the same handchop, the power was different -- compared to Dramaturgie’s fist the impact point was smaller, but the power was more focused.

Both our heads flew away.
