The artist had to delete his old galleries on Pixiv, due to the guidelines and uploaded them now in new Collection.
The cover contains the censored version, because the file in the Mega Link is broken. If someone still has the original cover, or if someone digs through the 35 pages/1377 pictures of KEYLUN's gallery (in theory it should be included there), feel free to upload it again.

The artist says that all his works are free and freely available, but if you still want to give him a little support:
