In a world where girls are much more than mere action figures, we follow the story of a young otaku, Hiroko, who becomes completely obsessed with her collection of action figures and video games. However, her life takes an unexpected turn when one day, one of her figures comes to life in a way she could never have imagined even in her wildest dreams. This figure is none other than a miniature version of a metal icon: a steel warrior with an explosive personality and a sharp sense of humor.
Together, Hiroko and her new metal-loving friend embark on a series of comedic and thrilling adventures as they try to navigate the strange world of everyday life and the challenges of adolescence. From competing in video game tournaments to facing school bullies and dealing with Hiroko's complicated romance, their increasingly strong friendship teaches them about loyalty, acceptance, and the importance of being oneself.
However, the story takes a dark turn when forces that want to reclaim the warrior begin to stalk them. Friendship and courage are put to the test, and both must face their fears and the obstacles of the real world. As this peculiar story unfolds, it explores the connections between passions and reality, demonstrating that, sometimes, the most valuable things in life are the unexpected connections we make.
