Ryoko Koizumi

A member of the Sukedachi police force tasked with exacting vengeance upon heinous criminals as a representative of the bereaved.

Ryoko is the only survivor of the AA Incident.

This famous incident was the trigger for the release of the "Revenge" Law, since the relatives of the victims not only wanted the criminal to be arrested or killed in a painless way, but to suffer the same as the victims suffered.

She totally disgusts men and can twist her body in a superhuman way.
