Experienced in fighting, as a top fighting witch, she has been Roland's personal bodyguard for a long time. Because of his polygraph ability, Roland was appointed as the director of the Security Bureau, which helped Roland a lot in foreign and domestic affairs and interrogation.

Protagonist information:

Roland Wimbledon: The Four Princes of Grey Castle Kingdom, a soul traveler from the earth, debuted at the age of twenty.

Cheng Yan, who was a mechanical engineer in his previous life, died suddenly because he was rushing for drawings. He crossed to Roland Wimbledon, and the fourth prince of the gray castle was trying to be a witch. As a modern man who received science education since childhood, he immediately stopped people from hunting witches.

However, he soon discovered from the rescued girl Anna that the laws of this world are different from the "real world" he is familiar with, and the magical power of "magic" actually exists.

In order to survive in the turbulent mainland environment, Roland decided to try to combine science and magic. With his knowledge and witch's ability, he made all kinds of industrial products beyond the times, thus promoting the development of science and technology in the territory, creating an environment in which witches and ordinary people lived in harmony, and gradually bringing the western border of Grey Castle and even the whole kingdom under his control.

At the same time, the secret of the birth of the church and the truth of the war between God and Italy were slowly uncovered.
