In a world where magic and industry clash, Release that Witch follows Roland, a modern-day engineer who finds himself mysteriously transported to a medieval fantasy realm and reborn as a prince. Armed with scientific knowledge from his past life, he quickly realizes that the kingdom’s only hope for survival against encroaching demonic creatures and political turmoil lies in harnessing the power of witches—women persecuted for their magical abilities. Roland defies tradition by sheltering these outcasts, forming an unlikely alliance with Anna, a powerful witch capable of controlling fire. Together, they combine her magic with his engineering ingenuity to pioneer revolutionary technologies, from steam engines to firearms, transforming a crumbling fortress into a beacon of progress. The series blends elements of fantasy, science fiction, and political intrigue, exploring themes of innovation, prejudice, and redemption. As Roland navigates treacherous court politics and battles monstrous threats, he must convince a suspicious populace that witches are not curses but the key to a new era. This ambitious saga offers a fresh take on the isekai genre, driven by clever world-building and a cast of compelling characters fighting for a future where science and sorcery coexist.
