Release that Witch

A modern-day engineer finds himself in another world, where he becomes a prince in a land that resembles medieval Europe. But this world differs in one striking way: witches exist, and they wield genuine magic. Rather than treating their abilities as a threat, the prince sees them as a force that can help drive progress. He sets out to save the witches and free their powers, while exploring the world, resisting demons, uncovering a conspiracy, and advancing technology.
