Prisma wants to be a cartoonist - but she's rather obsessed with magical creatures, looking for evidence for their existence and because of that not finding much time to work on her cartoonist carrer anymore. This is until her friends sign her up at an art academy. Prisma goes there and finds some new friends to work together with on a project for the summer party that's gonna happen in a few weeks. But there is one problem: The students at the art academy mysteriously lose their creativity, and soon even Prisma's new friends do. After a weird dream, Prisma accidentally summons a "Spacecat-Spirit" who watches over a bunch of legendary powerful crystals - and one of those crystals is - when used in the right way - able to give the cats their creativity back.
