Synopsis
People have created countless worlds, each born from the distinct imagination of its creator. Souta Mizushino is a high school student aiming to become such a creator by writing and illustrating his own light novel. While watching anime for inspiration one day, he is momentarily drawn into a fierce battle scene. Upon returning to the real world, he realizes something is off: the anime's headstrong heroine, Selesia Yupitilia, has somehow come back with him. Before long, other fictional characters appear in this world, carrying the hopes and wounds of their own realms. A princely knight, a magical girl, a ruthless brawler, and many more now crowd the streets of Japan. The most puzzling among them, however, is a woman in full military regalia called "Gunpuku no Himegimi," who knows far more than she should about the creators' world. Yet no one knows her true name or the world she comes from. Meanwhile, Souta and Selesia work alongside Meteora Österreich, a calm and composed librarian NPC, to uncover the meaning behind these unnatural events. With powerful forces at play, the once clear line between reality and imagination continues to blur, leading to a fateful meeting between creators and those they created.
