To be or not to be a magical girl.
Guest has just transferred schools due to family circumstances.
There, you meet four high school students, each with different grades, clubs, and personalities. A downer library committee member, a cooking-loving glutton from the home economics club, a timid broadcasting committee member, and an art club member who speaks like an old man.
These four, who aren't even childhood friends, share a secret commonality that no one knows.
One day on the way home, a mysterious mascot appears before Guest and the four students.
"Do you have a 'wish' you want to come true?" "Make a contract with me and become a 'magical girl'!"
To grant their wishes, the four become magical girls and fight mysterious monsters.
