Sometimes writers, artists, and other people involved in a work take to their series so much that they make their own Fan Works. These are non-canon or at most semi-canon, though fans tend to take them more seriously than fan works created by ordinary fans. The quality of the fan works varies, but many are rather in-character or on-model thanks to the person's experience with the series.
There are various mangakas that started in hentai before making SFW mainstream works, but some of them continue making hentai fanworks (some of them Spin-Off of their own series) under different pen names and doujinshi circles.
The inversion of Official Fan-Submitted Content, which is when fans make contributions to a specific work.
Can run into What Do You Mean, It's Not for Kids?, if the source work is kid-friendly but the fan work is not, only to fool more easily because the creator works on the source officially. Compare to Running the Asylum, Word of Dante, Word of Saint Paul. Can often be found on a Line to God. Contrast with Fan-Work Ban, which is when creators disapprove of fan-works, Promoted Fanboy, for when someone who previously made fan-works is allowed to officially contribute to the work they're making fan works of (said fan may still make fan works of said work after that), and Ascended Fanon, for when fan works and ideas are canonized.
Compare Side-Story Bonus Art, which is official art made by the main source.

In it, Brief collected all Panty's pieces and assembled her again but with something wrong, and Nova reappears with Identity Amnesia. Whether this is Canon or not is debatable, but it's valid for the fans at least.

Most agree it's probably the fic Don't Go, but ND hasn't confirmed or denied this. The fic is now commonly accepted as canon by the fanbase, since it doesn't contradict anything we see onscreen and in fact fills in a couple gaps.
