Teigu

The Teigu (帝具) are mysterious and extremely powerful relics that exist in the world of Akame Ga Kill! 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 be living creatures. It is implied that a form of magic was used to create them.

Origin
The Teigu were created on the instruction of the First Emperor, who feared that the Empire he had founded would eventually fall. To prevent this, he ordered many scientists to make strong weapons and defenses, and the Teigu are the result of their efforts. There were 48 Teigu in all, but almost half of them were lost during a civil war about five centuries before the start of the story. Several Teigu have been seen to be destroyed; it is not known how many of the original 48 remain.

Many Teigu were created from the remains of Danger Beasts that had unique powers, imbuing the equipment with special abilities. Many weapon and armor type Teigu were forged from a rare metal called Orihalcum. Teigu are not limited to one ability; some are known to have secret powers that are yet to be discovered, and some have powers that are lost to history.

Usage and Limitations
While the Teigu give 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, and a user's first impression of it affects their compatibility. The user of a Teigu must be compatible with the Teigu to wield it.

Biological Teigu are shown to be capable of regenerating after serious damage but are not indestructible; if their core is destroyed then so is the Teigu.

If two users of Teigu were to fight each other, one of them is guaranteed to die.
