Unbreakable Machine-Doll

Unbreakable Machine-Doll (機巧少女は傷つかない, Mashin-Dōru wa Kizutsukanai) is a Japanese light novel series written by Reiji Kaitō and illustrated by Ruroo. Set in an alternate early 20th-century United Kingdom, it explores a world where "Machinart," a blend of magic and technology, brings artificial intelligence and life to dolls called "Automatons." These Automatons serve as military weapons, with their controllers known as "Puppeteers." The story follows Raishin Akabane, a Puppeteer from Japan who enrolls at the Walpurgis Royal Academy of Machinart in Liverpool with his Automaton, Yaya, seeking revenge on a mysterious genius who killed his family. The Academy holds the "Night Party" every four years, where Puppeteers fight using their Automatons for the title of "Wiseman." The light novel series, published by Media Factory under their MF Bunko J imprint, spans 17 volumes and has been adapted into manga, a 12-episode anime television series by Lerche in 2013, and video games. The series combines elements of action, fantasy, and harem genres.
