Mirai Asahina is a 13-year-old girl who will soon be in her second year of middle school. One moonlit night, Mirai witnesses a wizard girl on a magic broom falling from the sky. The girl's name is Riko. Mirai wants to help Riko, who is hungry and weak, but a suspicious man appears...

Mirai and Riko have become legendary magical Pretty Cures. Riko brings Mirai and Mofurun, a teddy bear who is able speak, back to the magic school. However, the vice-principal is angry that Riko brought back a non-magic person and wants to expel her from the school. Mirai tries to meet the principal in order to protect Riko…

Mirai decides to attend the magic school to study about magic during her spring vacation. She rides a magic carpet with Riko and Mofurun to the magic mall to buy magical items. Meanwhile, the Linkle Stones are robbed by something like a spider’s thread!

In the magic school library, there is a Forest of Knowledge where even the principal can get lost. While chasing after a paper butterfly in her lesson, Mirai heads to the library and gets lost in the Forest of Knowledge. While Dokuroxy’s minions approach, Mirai and Riko find a mysterious shiny book in the library…

Mirai’s second lesson is to boil a magic kettle and make tea on a cold island. Although the students’ magic did not work in the beginning because of the cold, Mirai and the other students manage to successfully boil their magic kettles after they are warmed up by a game that Mirai suggested. However, Riko, who didn’t join the game, couldn’t use her magic well and gets in a fight with Mirai...

The next lesson is taught by the teacher Liz, who is an educational intern and Riko's older sister. The content of the lesson is to make a shape with water using a magic wand and then hold the shape for 10 seconds. Riko tries to show off in front of her sister but after failing she quarrels with Liz and runs out of class.
