Requesting for the artworks of やすたか. He was a pixiv artist active around 2015 creating asphyxiation artworks,and set all his works private about five or six years ago. Unfortunately there are no archives or galleries of his works. Below is the full set of his works according to saucenao, but only a couple of them are still available on Internet. I will post all I have in this thread, and hope anyone who has saved his other artworks can help to find them back.
