Teigu

History
The Teigu are mysterious and extremely powerful relics that exist in the world of Akame Ga Kiru! They are rare and only the strongest of warriors are able to wield them. Some have the appearance of equipment or weapons, while others seem to resemble living creatures. The user of a Teigu must be compatible with the Teigu to wield it.

The Teigu were created when the First Emperor who created the empire was afraid that the empire would eventually fall. To prevent this, he ordered many scientists to make strong weapons and defenses. Thus, the Teigu were created. There are 48 total Teigu in all, but almost half of them were lost during a civil war about 500 years ago.

While Teigu gives its user amazing powers, they are not almighty. It is stated that there is no Teigu that can bring the dead back to life. Even if a user is strong enough to use a Teigu, it can still reject him, as a user's first impression of it affects its compatibility.

It is hinted that a form of magic is used to create them. All weapon and Armor Tegiu are made up of a rare metal call Orihalcon.

Bio-Teigu's are shown to be strong but not indestructible, as if the core is destroyed then so is the Teigu. This rises the question of how many Bio-Teigu's have been destroyed and if all similar Teigu can be destroyed.
