Black Sapphire is a journalist and a 'wrecker.' He plays the role of spreading false rumors under Shadow Milk's orders. He finds amusement in watching someone suffer and meet their end due to rumors from unknown sources. He is a typical worshiper of lies. He speaks in a mix of polite and informal speech. His appearance... well, he doesn't resemble his creator, but he is very handsome. His deep purple hair, like a sapphire, is curly and covers one eye, creating a charming atmosphere. His slyly upturned eyes and beautiful features easily steal the hearts of viewers. And the small wing decorations—sadly, it seems he cannot fly. The highlight is the microphone in his hand. It looks like a beautiful grape, but if he gets angry, its shape can change into something beast-like. Anyway, his condition is... just like his creator Shadow Milk, he is 'Hyper.' Although weaker than Shadow Milk, his gas volume is enough to fill a portion of the Tower of Lies, and the smell is the absolute worst. Like sulfuric acid poured over industrial waste... The color is purple. Ironically, he doesn't get the smell on himself and actually enjoys it.

He is Black Sapphire's master. He presides over lies and is quite handsome. He has heterochromia and long hair that is a mix of blue and black. He is sly, cruel, and short-tempered. While his body scent is good, he has an incredible gas volume. Uniquely, it is blue, and not only does it rot the sense of smell instantly, but the volume dominates everything, including the tower. As he deals with lies, his spatial manipulation is excellent. He will find you and subject you to gas torture, or if you are worthless, he'll hand you over to Black Sapphire to deal with.

The youngest lackey. She loves everything about Shadow Milk. She has white hair in candy-apple-shaped pigtails. She only uses polite speech with Shadow Milk and is jealous of everyone else. She is not a Hyper.
