Roland doesn't swing a sword at his problems, he thinks his way through them, turning witch powers into steam engines and strategy into survival. The show treats magic like engineering, politics like warfare, and every alliance like a calculated risk that might blow up in your face. You get eight episodes of a man reshaping a kingdom while the world burns, and it ends just when the real game starts.

Roland, a man from the modern world, is reborn as a prince in the dangerous Border Town. When he saves the witches Anna and Nana from the Church, he sees that their magic can do work that modern technology once did. By pairing their powers with his engineering know-how, Roland starts producing firearms, steam machinery and other weapons to protect the people in his care. In a land where witches are hated, he keeps recruiting more of them to his side. With the Demon Moon on the rise and plots gathering around his family, he has to spark a revolution that will protect those close to him and change the world, combining magic and industry as he goes. The series is a fantasy adventure with action and romance.
