En is shown to be the Corporate boss of a business that apparently sells automated brooms and other objects. He’s shown to be a man who has a large expansive group of lackeys, and is currently Noi and Shin’s boss. He wears a mask that holds over his mouth similar to a surgeon’s mask, and his smoke can turn people and objects into mushrooms. He is quite fond of mushrooms, that’s why he themes every product he sells after them and every meal he eats is made from mushrooms. While all magic users can be considered “the bad guys”, En is more or less the lead villain.
