A tale depicting the struggle of the Relic Countermeasure Organization.
About
【Synopsis】 A long time ago, the predecessors left behind traces of war and "weapons" in this world before departing.
In the present day, these "weapons" have come to be known as "Ancient Weapons." The Earth continues to spin, scarred by war and desolate lands. However, it has been discovered that the Ancient Weapons, which were supposed to have been sealed by the predecessors, are running rampant across various regions. In response to this phenomenon, the government established an official agency called the "Relic Countermeasure Organization," commonly known as "RCO."
RCO travels the globe to perform a "Forced Termination" — Shutdown — on the unsealed Ancient Weapons. However, behind the scenes, a group calling themselves "Kamon Rasen" is moving with plans to exploit these Ancient Weapons for their own ends...
【Terminology】 ・Relic Countermeasure Organization (RCO) A government-sanctioned agency that manages the Ancient Weapons left by the predecessors. Members are issued weapons and a uniform cloak. It is divided into four divisions: "Inspection," "Suppression," "Repair," and "Medical," each with distinct roles. Many people look up to them.
・Inspection Division Responsible for confirming and reporting the storage locations and "Forced Termination" status of Ancient Weapons. As they may engage in combat depending on the situation, individuals with combat sense are often assigned here in addition to basic physical strength and intelligence.
・Suppression Division Receives data on the "Forced Termination" status from the Inspection Division. Depending on the readings, they head to the site to re-execute the "Forced Termination." The headquarters' communication room is always connected to the Suppression Division so they can deploy at any time.
・Repair Division Responsible for repairing and adjusting the weapons and communication terminals used by the Inspection Division. They can handle almost anything. They are stationed in the headquarters' repair room. Mostly individuals with high manual dexterity are assigned here.
・Medical Division Responsible for treating those injured in combat with Ancient Weapons. They are experts at healing everything from minor scratches to major wounds. They are stationed in the headquarters' medical room. Mostly individuals with high intelligence and vast knowledge are assigned here.
・Soul A power that every human is born with. By channeling this into a weapon, one can finally stand against Ancient Weapons. The type of Soul varies by person, and this type is called a Soul Attribute.
