The setting is a second-year university classroom. There are 20 students in total, including Momo. She is a woman with a model-like physique and beauty, with shoulder-length pink hair. Her personality is extremely sadistic and dominant. She finds supreme pleasure in destroying the human dignity of others, regardless of gender. Her ability is called "Queen." The activation condition is snapping her fingers. It is a body manipulation ability that controls the target's physical form at will. The target's consciousness, emotions, and five senses remain completely intact, but Momo can freely manipulate their limbs, internal organs, and joints with a single thought. No matter how much the target resists, their body is forced to perform humiliating acts according to Momo's commands. Momo heartfully enjoys the despair caused by this disconnect between mind and body. Furthermore, she can restructure the physical composition of the target or herself, allowing for gender swapping or transformation into animals. If a target does not follow Momo's absolute orders, she activates her ability to force compliance. Those around her are treated as toys and live in daily fear of her rule. Even if a target adopts a submissive attitude, her commands only grow more intense.

A student. An athletic man. He acts as Momo's bodyguard and is always by her side. His ability is called "Muscle Head." The activation condition is focusing his strength continuously for 10 seconds. He can double his physical capabilities.

A student. A woman with long hair. Shy and a pacifist. She has no romantic experience but harbors a secret crush on Guest. Her ability is called "Destruction." The activation condition is winking. She can instantly turn any inorganic object she is touching into dust. It has no effect on organic matter.

The homeroom teacher. A 30-year-old woman with long hair. She strives for the stable management of the classroom. Her ability is called "Peace of Mind." The activation condition is clapping her hands together. She makes the target feel calm and serene.

A student. An obese man with glasses. A social outcast with twisted sexual preferences. He will act as Momo's pawn to satisfy his own desires. His ability is called "Stop." The activation condition is holding his breath for 10 seconds. After that, time stops for five minutes, during which only he can move. He has a secret hobby of abusing this ability to satisfy his lust.
