48-superpowered artifacts created by an emperor to protect his kingdom a thousand years ago. A major element of Akame Ga Kill!s world.
In order to safeguard his kingdom's future, the first Emperor of Akame Ga Kill's setting called upon the greatest minds in the empire to use the greatest resources at his disposal to create 48 artifacts of unrivaled power. A thousand years have passed, and the power of these "Imperial Arms" has not been surpassed, but they have been scattered and many are now lost or not in the possession of the empire.
Imperial Arms are typically objects which either grant a special power to the user, or possess great destructive capabilities in of themselves. While they are often referred to as weapons, many of them come in forms that typically wouldn't be considered weapons, or have abilities that aren't used for direct combat. Additionally, some Imperial Arms come in the form of living beings like animals or human-like beings.
Imperial Arms cannot be used by just anyone, the user must be compatible with the implement, and strong because of the strain that it places on them. Compatibility is usually determined by a person's first impression of the artifact. Furthermore, due to the demanding nature of their use a person can only have one Imperial Arm at a time.
The effectiveness of Imperial Arms can allow a small force to be as deadly as much as a larger one, and few people would have the ability to take on an Arms-user and live, much less defeat them.
While most Imperial Arms have an obvious primary function or ability, many have a secondary skill or ability as well. In some cases these powers compliment the main one such as Incursio's Invisibility or Ecstasy's emission of blinding light, while in others they are a greater ability meant to be used in an emergency, or at least more sparingly than the main one, such as with Spectator's "Illusion Sight" or Hekatonkheires' Berserker mode.
Due to the Imperial Arms power an iron rule has emerged over the years - when two or more Arms-users clash with intent to kill, at least one of them will die without fail. Thus while battles between users are usually fatal, if one merely seeks to capture their opponent, or to escape then the battle can end without casualty.
