It's a series about middle school, but with the Kirby characters in it! Kirby makes some new friends, including the two star twins Starlite and Starbrite, some new rivals like the bully Randy and the mad scientist kid puffball Dexter who makes all these demon-beasts to try to get rid of Kirby.
The classes the characters take are mixed fake with real life. Some of the real classes are math, reading and history. Some of the fake classes include Copy class (for puffballs only) and Weapon class (non-puffballs only).
Jane also appears in it, she makes new friends like Samantha and Claire but she seems to be in love with both Kirby and Dexter, giving them another reason to be rivals.
