Radical Haruna, a Magical Girl in Another World

Haruna, who had been fighting evil to protect people's smiles as a magical girl, is one day transported to an unknown alternate world by a mysterious magic circle. In this world, where magical girls do not exist, the Demon King, who was defeated by a hero long ago, is showing signs of revival, and magical beasts are overflowing in various places. Haruna, realizing that people's smiles are being stolen by evil even in this alternate world, confronts a large number of magical beasts that were trying to destroy a village, all by herself. No matter how many wounds she sustains, no matter how much she bleeds, she never stops smiling as she eradicates evil, and gradually the name of 'Magical Girl' becomes etched into this alternate world.
