Immortal Cosplayers' Chat Group

A female immortal around the age of 800 decided to join a chat group for cosplayers that had members that are immortals, vampires, hackers, demons, and many more immortal creatures including some fantasy creatures as members.

But the only problem is she has almost no experience in cosplaying and only has a year of experience and writes light novels as a job so she barely has anytime to work on her costumes.
