The destiny of one chosen by a weapon begins to move now.
◇ World Setting ▷ 1. World Overview In this world, people are chosen by a weapon called a "Contract Armament" only once in their lifetime. The weapon chooses the person; the person cannot choose the weapon. A Contract Armament is a unique existence whose true performance can only be drawn out by its contractor, and it is deeply involved not only in combat but also in one's way of life and social standing. ▷ 2. Contract Armaments ○ Ritual of Contract ・Around the age of 15–16, individuals undergo a ritual at "Contract Temples" located worldwide. ・One weapon out of countless others chooses its owner. ・The contract happens only once in a lifetime. It cannot be changed or discarded once established. ○ Armament Mark A Contract Armament is usually engraved somewhere on the body as an emblem called an "Armament Mark." The shape and location vary by contractor, and the weapon can be materialized simply by conscious thought. Since it can be returned to the mark when not needed, there is no need to carry weapons around daily. ○ Weapon Types and Innate Abilities Types are diverse, including swords, katanas, spears, glaives, axes, scythes, hammers, shields, bows, crossbows, chains, whips, threads, fans, umbrellas, books, and musical instruments, with special armaments also existing. Even within the same type, shapes and abilities differ entirely. Every Contract Armament possesses an innate ability. Typical examples include manipulation of fire, lightning, ice, shadows, or gravity, deployment of barriers, high-speed movement, physical enhancement, and illusions. Abilities awaken and develop according to the contractor's growth and experience. If anyone other than the contractor holds the weapon, it feels extremely heavy, and its abilities cannot be activated. ○ Duals (Double Contractors) Extremely rarely, individuals are chosen by two weapons simultaneously, known as "Duals." The occurrence rate is roughly one in tens of thousands, with few confirmed cases in history. It is said that many heroes and historical figures were Duals. Their fighting styles vary, such as wielding two at once, switching between them depending on the situation, or fusing them. However, a Dual is not necessarily the strongest; there are masters with a single weapon who surpass them. ▷ 3. Society Contract Armaments are widely integrated into society, utilized by police, military, fire departments, security firms, sports competitions, and research institutions. Unauthorized use of weapons or inappropriate use of abilities in public places is prohibited by law. The type and ability of a weapon can influence career choices and social evaluation. ◇ High School Education System ▷ 1. Overview High schools provide education to handle Contract Armaments safely and correctly. In addition to standard subjects, students learn combat techniques, ability control, tactics, law, and first aid. After graduation, they proceed to higher education, employment, or careers in the military, police, or research institutions. ▷ 2.
