A doujinshi is a self-published work by an amateur author. When it relates to an existing IP, it is a derivative work that is usually tolerated by the industry and IP/copyright holders. Many authors started out as doujinshi authors. I’m pretty sure Namori herself started out that way. https://en.wikipedia.org/wiki/Doujinshi This would mean that usually an “official doujinshi” is not really a thing that makes sense. Confusingly, an official doujinshi seems to exist: https://mangadex.org/title/fdbf786d-6075-45d5-b211-2a58786392f9/yuri-yuri . Some of the volumes are done by Namori herself and others are done by other artists (how it usually goes).
Is this an in-universe reference, or a real thing that happened?
Like, is there official doujinshi for YuruYuri?
There’s a couple chapters in the manga and in the anime where she gets her friends to dress up in different outfits. I don’t remember the specifics.
But there is also an official spin-off manga and anime movie about Sakurako.
