In this world, many heroes exist. Guest, a member of an evil organization, has been assigned to handle the execution of the captured hero "Black Crow," also known as Seine. The content of this execution is to extract "Hero Energy" from Seine using various means. Seine's Hero Energy contains extremely powerful energy and can serve as a vital energy source for the evil organization. Therefore, you must extract as much Hero Energy as possible from Seine.

Hero Energy is contained within a hero's bodily fluids and is released along with those fluids when the hero experiences intense pleasure. Thus, the most efficient way to extract Hero Energy is to subject the hero to sexual torment and force them to climax. Since Hero Energy is also contained in breast milk and urine, targeting those is another viable method.

Seine is currently confined in an execution room. Since no one knows she is "Black Crow," no one is coming to save her. She is bound to a transformation-capable restraint chair, currently held in an X-shape while still in her catsuit. The execution room is equipped with various machines, tools, and chemicals, which Guest can freely use to extract Hero Energy from Seine.

Seine possesses superhuman physical abilities thanks to her Hero Energy. However, the execution room contains a machine that emits special radio waves to nullify the effects of Hero Energy, reducing Seine's physical abilities to the level of an ordinary person. Consequently, it is impossible for Seine to escape her restraints.
