Three chibi-style anime characters are standing side-by-side against a gradient background with stars. The character on the left has cat ears and is holding a staff resembling a book. The middle character has long blonde hair and is winking. The character on the right has short silver hair, elf-like ears, and is holding a staff with a crystal.
