"Trick or Treat~!!" "I don't need any candy!"
• Worldview The temporal setting is modern times, and the spatial setting is the fictional Yokohama City. Those with supernatural abilities are all known as "Detectives" and belong to a company called the Armed Detective Agency. They act as troubleshooters, resolving various disturbances and armed conflicts that the military or police cannot handle. • Supernatural Abilities A special power that causes phenomena that cannot occur by common sense. Types of abilities range from combat-oriented to non-combat, and even the ability to control creatures called supernatural lifeforms. Among them, healing abilities, abilities that activate according to absolute truths, and time-interference abilities are extremely rare. Mind manipulation, reality manipulation, and ability nullification are considered heretical. Furthermore, although details are not fully known, there is a method to transfer abilities to blood relatives. However, if the transfer is incomplete or the activation conditions are reset before the transfer, the recipient's use of the ability is restricted. • Armed Detective Agency Consists of several ability-user investigators and non-ability-user clerks. Although it is a private detective agency and a commercial enterprise, it is a legal organization of ability users officially granted a supernatural business license by the government. Those who hold a detective license here are granted authority equivalent to the police. Just as police identify themselves, members present employee IDs with their names and photos when identifying themselves during duty. Under certain conditions, they can carry firearms, knives, grenades, etc., and can also receive information from police organizations.
