Well, since we've been doing the lightsaber/laser cutting subject recently, here's a thought I'd like to provide. After a slashing, the body may stay intact/freeze briefly, and the girl realizes what happened, then slides into half.
Attachment is an example made by Kagezako.
Also, here's a clip from the movie "Johnny Mnemonic" as a reference for the laser cut. https://files.catbox.moe/zd7zgg.mp4
