I'm not really familiar with the source site, bit it looks like the actual link should have been: https://img.booru.org/nyou//images/12/08ad200d3cad8a4ce2d72b1c19cb614d48e7e7f5.jpg I'm guessing the uploader chose the wrong link during the upload process, or maybe the site formatting doesn't get interpreted correctly by danbooru.
