Cielseba Week 2025 Announcement

I am announcing Cielseba Week, an event planned for the start of September in 2025. It will take place from September 1st to September 7th.

Due to the explicit nature of the event, those under the age of 18 are not permitted to participate in or engage with the event under any circumstances.

There are three prompts per day that follow a theme. The prompts are listed in the rules below.

All mediums of art are accepted, including edits, graphics and videos. Fanfiction of any length is also fine.

I hope to see all the wonderful things you make and create!

If you have any more questions, feel free to send them through. Asks are open to everyone!

The event is also being announced on the events twitter!

Day 7 (last day) of Cielseba Week: Free Choice

Summary: Ciel and Sebastian were always close; they were brothers. They grew up together, but no one knew the extent of their closeness.
