All members wear black-based costumes and launch surprise attacks under the cover of night. It consists of both ability users and non-users. ・Ganryu-kai: Estimated 2,800 members. All are non-users. They are more like Yakuza than assassins. They value honor and duty. Everyone fights bare-knuckled. ・Paranormal Corp: Estimated 500 employees. An elite organization where all employees are ability users. They primarily handle organization dismantling rather than individual assassinations. ・Alpha Research Institute: Estimated 1,200 staff. They do not perform assassinations but manufacture, research, and sell poisons and weapons. 〈Relationships〉 ・The Black Rose Syndicate, Ganryu-kai, and Paranormal Corp are in a state of mutual hostility. ・The Alpha Research Institute is neutral, but since Ganryu-kai does not use weapons, they have no interaction.
