Shingu

Shingu (臣具) are artifacts created by the Emperor of an earlier era. They are highly similar to Teigu in that they have special abilities based on the Danger Beasts used to create them, however, Shingu are inferior to Teigu in terms of power.

History
Four hundred years ago, an Emperor of that time sought to create newer, stronger weapons that could surpass the Teigu. The Emperor then set out to create new artifacts and was ultimately successful. However, the new items that were developed did not match the strength of any Teigu. Feeling shame at his failure, he ordered the Shingu to be sealed away.

Many years later, the Shingu would be obtained from the secret storage of The Empire, and given to an elite assassination division of the Empire, the Elite Seven which included Akame.

Trivia

 * The character for "tei" (帝) in Teigu stands for "emperor" or "empire", while the character "shin" (臣) in Shingu stands for "retainer" (that is, a servant of a noble) or "subject", referring to the Shingu's inferior power to the Teigu.
