Release That Witch
Cheng Yan travels through time, only to end up becoming an honorable prince in the Middle Ages of Europe. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land. Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders from the realm of evil.

Roland had also completely wiped the Fourth Prince's memories from his mind, and besides trying to mimic the Prince during his first month after traversing the space and time, he never considered it ever again. His ministers were afraid to question him, and he didn't have to hide who he was from the witches, so he became more and more careless.
However, Tilly was no ordinary witch.
Besides being Prince Roland's sister, she was also an Extraordinary.
