Living Weapon

Living Weapon (現存武器, Genson Buki) is a unique form of Holder Magic that gives its users the ability to personify their weapon, essentially giving it life and creating an entity to serve their wishes.

Overview
Living Weapon is a Holder Magic that allows its user to personify a weapon of their choice, granting it sentience and the ability to shapeshift between a weaponized and human-like form. These beings are completely autonomous from their user, possessing physical and magical abilities of their own. The weapon’s abilities develop as they adapt rather than being a direct result of the owner’s wishes although the wielder can encourage the weapon to develop certain abilities.

The magic allows the being to switch between being a weapon and being a human but they are incapable hybridizing their forms. Additionally, damage to the weapon or body is reflected in both forms, though minor wounds on the body do not carry over. If the weapon is broken in two, so is the body, and should the weapon be mended, the body can be too, though any dysfunctions carry across both forms. If the humanoid is killed, the weapon breaks into an irreparable form.

The beings that are born from weapons are physically and mentally reflective of the weapon they personify and the one who cast the spell, making them intimately bonded to their wielder. Living Weapons are born from their caster’s soul, creating beings that are unique to each and every person and linking them together. Because of a weapon’s autonomy, they may adopt conflicting ideas to their wielder but they are intrinsically bound to each other. The death of a wielder results in the death of the weapon, and passing a weapon onto others results in the creation of an entirely new entity.
