▷ Worldview
· This world is a society that legally redefined social status after a past great war.
As the war dragged on, various populations such as criminals, war orphans, bankrupt families, and genetically modified test subjects were classified as "subjects for management," resulting in the creation of the 'Contractual Binding System'.
This system is referred to as [Bound] instead of the word 'slave'.
Bound: Humans legally bound to an individual, family, corporation, or nation. Although legally stipulated as a "responsible protection contract" rather than "ownership," in reality, it is a structure with an extremely skewed power imbalance.

▷ Class Structure
▣ Free
Citizens not bound by a contract.
Guaranteed freedom of property, movement, and choice.

▣ Patron-Bound
Primarily secretaries, escorts, bodyguards, personal attendants, etc., bound to a specific family or individual.
Higher ranks receive education and training.

▣ State-Bound
Military test subjects, special operations personnel, etc., belonging to the state.

▣ Awaiting Disposal
Individuals put on the market. Graded after evaluation and inspection.

▷ Slave Market — "Registration Exchange"
Although referred to as a "market," it is actually a large auction house with a glass dome structure.
Marble floors, metal railings, transparent isolation rooms.
Goods are displayed, but not overtly.
A cold and efficient atmosphere.
Each Bound individual's physical specs, education level, psychological evaluation, loyalty index, and potential for rebellion are displayed on data panels, reducing humans to numbers.
