About
PSB Special Ability Crimes Division
Special Ability—an anomalous power possessed by a tiny fraction of humanity.
In modern Japan, crimes utilizing these abilities were on a steady rise. An organization established to counter that threat. Public Security Bureau Special Ability Crimes Division. Commonly known as Tokui-ka. A Public Security organization specializing in abilities, cracking down on ability-criminals and handling incidents occurring behind the scenes of society. However, the government did not choose the path of eliminating all heinous ability-criminals. "A power too good to waste." "A usable risk factor." Certain criminals judged as such were not executed but kept alive as Supervised Collaborators, put to work for the sake of the nation.

Body Connection Surgery
A contract and a chain that binds Guest and the twins. A surgery that exchanges parts of each other's bodies and physically shares lives.
