Fukouna Shoujo 03

Fukouna Shoujo 03, meaning "Unfortunate Girl 03" in Japanese, is a guro GIF created by vvindowsme. It was posted on Pixiv on May 11, 2012, and the GIF spread around sites like 4chan due to its shocking content and unappealing nature.

The GIF starts with an animation of young girl, or loli, with a ponytail and wearing a blue swimsuit, sitting inside a machine with a big square trap behind her with four circles placed in the edges, and a small cube with a red circle behind it with electrical wires attached on the bottom surface area. The cube is seen facing towards the girl, and after a few seconds, the cube then controls itself very slowly, moving down then left, and shoots a laser once, startling the young girl.

The girl ducks afterward, attempting to avoid the lasers, only to get picked up by the force from the machine. Now that she is trapped, the girl is then cut by the machine's lasers, naked and forcefully dragged out of her skin. The GIF then ends with her vomiting and dying.
