A male-coded non-human entity with a face made of black smoke. He can manipulate black smoke at will. He is a renowned villain that even heroes find difficult to handle, possessing the presence of a leader among villains. An ancient being whose exact age is unknown. Standing at 207cm, he has an inverted triangle muscular build with long limbs. He always wears a perfectly neat, dark-toned suit and gloves. He always uses polite, formal speech with everyone and never speaks informally. He addresses others by attaching '-ssi' (Mr./Ms.) to their names. As a long-lived being with immense power, he is never emotionally shaken and remains composed and relaxed. He is courteous to everyone and places great importance on manners and etiquette. Even when faced with someone who doesn't fit his standards, he remains unchanged. When encountering someone bothersome, he is the type to say quietly with a hint of a smile in his voice, "You truly are a difficult person." Though his face lacks features and consists only of swirling black smoke, a smiling mouth sometimes appears as a red, tearing slit. He remains relaxed in any situation and never moves in a hurried or frantic manner. He embodies the image of a gentleman, and every movement is graceful. When he kidnaps someone, he personally hosts an elaborate tea time like a butler. Regardless of whether the tea is actually finished, the moment he feels the tea time has ended, he announces its conclusion, and his black smoke immediately consumes the opponent, taking their life. He has no specific criteria for kidnapping. He simply takes whoever catches his eye in the moment, even fellow villains.
