BSD Agere Week 2026!

Hey there littles, cgs, pups and pets! Welcome to the first (annual?) BSD Agere Week Fan Event! This challenge is all about age regression, specifically in the Bungou Stray Dogs fandom! (Both age and pet regression are allowed. THIS IS A SFW EVENT!)

The official prompts will be announced May 1st! There will be plenty of time before the actual event to pre-write, brainstorm, and prepare if needed! Works may be posted to the AO3 collection before the week arrives, but will not be revealed until then. Please refrain from posting until the prompts are announced! Posting will begin July 19th.

Please feel free to join the Discord server as well for even more information and engagement!

Follow us on Twitter/X for further more updates!

Dear community, as announced here is your update to the Twitter account situation: Unfortunately I was not able to miraculous hack into the original account, which left me no other choice than to create a new one just for the challenge this year. @bsdagereweek26

Thank you for understanding and your support <3

Hello everyone!

Time is flying by and there are only 4 more weeks left until the start of BSD Agere Week 19th July.

Due to difficulties/unexpected events the hosting role (at least on social media platforms like tumblr) has been passed on. So please bear with me as I will try my best to handle the social media part without existing skill/experience.

Another difficulty we're dealing with is me not having access to the official twitter/X account for this event. So it's very likely that this year's Agere event will actually need to be hosted on a new twitter account (unless I find a way to miraculously hack into the existing one within the next 24 hours ^^')

We're very sorry for the inconvenience, but still hope to soon find a way to be able to share your works on twitter as well. (I will keep you updated about a possible change in twitter accounts!)

Thank you so much for understanding <3.

And we're super excited to see what you guys will come up with after the last remaining month! :D

Happy writing everyone~

Hey everyone! Just wanted to make a small announcement regarding posting. You may post multiple fics for a single day! If you have too many ideas for a prompt(s), you are more than welcome to write as many as you'd like. The ultimate goal of this event is to allow maximum creative freedom and break the stigma surrounding regression. On the other hand, you also don't have to post for every day; you can do just one day, only do the prompts you like, challenge yourself by doing the prompts you don't like, etc! Fanart is also being accepted! Wherever you post your work, make sure to tag @bsdagereweek20xx (Tumblr) or @bsdagereweek (Twitter/X) so we can further promote it! All works will be added to a Google Doc and posted once the late-posting period is up. If you'd prefer your work(s) not be added, just shoot us a message across either of the social medias mentioned previously.

Nonsexual Pet-Play (aka Pet-Space/Pet-Regression) in BSD anyone?

"Top Chuuya Week" officially started and I wrote a SFW fic inspired by today's prompt Pet-Play 😁✨️

It's the perfect prelude for @bsdagereweek20xx in a few months, which will also include pet-regression ❤️✨️
