As of today, the only character taken in the entire server is Dazai, who I (Maven) will be writing myself. I am an experienced writer of many years, and I look forward to getting to interact with everyone! There is further info on the rules, application process, and more inside the server.
But generally speaking, popular characters such as Fyodor, Chuuya, Kunikida, Atsushi, Akutagawa, and many others are still available! Come soon to get exactly who you want! :D
