#669008 | COMIC Shingeki 2026-09 | 1,350 All original, not derivative works, published by a publishing company in a manga. No different than something like Shonen Jump.

Specify that it's "doujinshi" and not just "works". The categories of 二次創作 "derivative works" and オリジナル "original works" is all about self published doujins. A better description would be "Doujinshi that are original works instead of being parody of other anime/manga/game series"

Does this include any pre-existing IPs?

I think the same as the guy below. It should be original unless proven wrong or at least have a way to search only works without parodies (like how you can exclude tags -tag but with -parody) + original. I only read original things but I have to enter the doujinshi before knowing if it's original or not bc if you search with the 'original' parody you end up missing a lot of gems that don't have it.

If a hentai administrator or developer see's this, is possible to make it so that when the parodies field is blank that it would be count as an original? Or would it create too much noise for the "original" tag?
