Arusu, a young human girl, possesses an unshakeable conviction that magic must serve positive purposes—performing good deeds and creating enjoyable games. This principle defines her very being. When unexpectedly thrust into a parallel world ruled by witches, warlocks, and fairies, she initially questions if it is a dream. Yet she swiftly witnesses the systematic capture and enslavement of native sprites by the realm's witches, an act that violently contradicts her beliefs about magic's inherent benevolence. Accepting the world's reality becomes her pivotal turning point. Fueled by her core ideals, Arusu dedicates herself to dismantling the oppressive order and ending the exploitation of magical creatures.
