Harukaze Doremi considers herself to be the unluckiest girl in the world. Her parents are always fighting, her little sister makes fun of her, and her crush pines after another girl. If only Doremi could just wave a magic wand, she would have a much better life—or so she used to think. After a mishap with a real witch, Doremi becomes an apprentice witch herself, and it turns out she's pretty horrible at that, too. Now she and her two friends must study to become better at magic so they can become good witches. That is, if they can focus on their magic studies! The three apprentices will need all the luck they can get if they want to pass the witch exams and become full-fledged witches. Only then will Doremi's debt to the witch Majorika be repaid. Until then, Doremi will remain a useless little witch girl!

In the northern Kanto area in Japan, there is Binan City… At Binan High School, as per usual, the “Earth Defense Club (lol)” was a club that did nothing. The club members Kyoutarou Shuzenji, Ryouma Kirishima, Nanao Wakura, Taishi Manza, and Ichiro Dogou nonchalantly enjoyed tea while having pointless conversations that amount to nothing. All of them have now gathered at Kurotama Bath after school. When Ryouma pulls Kyoutarou Shuzenji by his arm out of water that he claims feels too good, together with his towel comes a pretty boy in strange clothing. These five boys are then dragged into a battle for the heir of the magical kingdom, Honila Land...

The older boys are graduating school and recount their memories together. The next day everyone defends the graduation ceremony against Zundar and Dadacha's Second Button Monster but Yumoto struggles using his love power.

Movie commemorating the franchise's tenth anniversary.
