En

Boss of the En family and is an elite Magic User. He is cousins with Noi and Kikurage's partner. He's also good friends with Chidaruma, who is the most powerful Devil. En controls most of if not all business within the Magic-User realm and is regarded as one of the strongest Magic Users in the world. He's shown to be a man who has a large expansive group of lackeys, and is currently Noi and Shin's boss.

Typically seen in loosely worn formal attire and wears his long, red hair spiked upwards. He has a large forehead and menacing eyes further defined by his lack of eyebrows. His mask consists solely of a mouthpiece resembling something between a gas mask and the mouth of a skull. Beneath the mask, he is revealed to have a thin mustache with a goatee. En is cool and confident in everything he does. He often enjoys quietly drinking tea or tending to his exotic garden of mushrooms. En is very full of himself and his capabilities. The very thought of someone laying a finger on him in a fight, the world's most powerful magic user, can cause him to lose control of his emotions and go berserk, turning everything and everyone caught in the crossfire into mushrooms. Despite being a pretty big narcissist, he has shown that he truly does care about the members of his family. He is especially fond of Kikurage, often worrying about her safety and well being above everyone else. Regardless of what others think or wish, En's desires come first and he'll do anything to get his way, even if that means killing, kidnapping or forcing them to do as he says, forgoing a more diplomatic approach.

En possesses a powerful transformative type ability that allows the smoke he can exhale from his mouth or fingers to turn whatever it touches into mushrooms. Despite the somewhat silly nature of his magic, by his own admission, most don’t understand the truly terrifying degree to which he has mastered his ability. The various applications of En’s power appear only to be limited by his creativity.
