The Onyx Task Force (or Onyx Knights) are a special group of knights who served under Charioce XVII.


The Onyx Knights are part of a task force who swear loyalty to the King Charioce XVII, and did not exist prior to Charioce XVII's reign. They work as his personal guard that perform duties from body guarding his majesty to taking out major threats. They are specially trained to take out gods and demons with the help of the green stones which grant them power.

"We offer our lives to execute our orders. That is what our unit does."

In order to become an Onyx Knight, one must place the magical green stone into one's chest. By doing so one allows the stones to drain one's life force at the cost of obtaining power. Other side effects include the formation of bruise-like spots all over the body with thick purplish black veins that pop out and the coughing up of a tar like substance. As a result, an Onyx Knight will gradually die a slow and painful death.

The Onyx Knights are extremely loyal to their cause and never hesitate to carry out a mission. Their lives have willingly been forfeited for Charioce XVII. The Onyx Knights will always be there to remind the king of his mission in case he begins to lose focus on their goal. Their connection with their king is rooted in their knowledge that the king intends to slay Bahamut, a feat at least the Captain considers noble and worth giving his life for.

However, the pinnacle of loyalty they show is the sacrifice of their bodies in order to power the weapon "Dromos" which their king shares their burden.

A weakness of the Onyx Knights is El, who possesses the ability to disable the green stones used to empower the Onyx Knights. Because of this, Charioce XVII spent two years tracking and hunting down El, desiring him either dead or alive. The Onyx Knights themselves regarded El as a major threat. Nina Drango is also capable of harming the Onyx Knights.

Their weakness is mainly derived from their abilities being focused on slaying gods and demons but not humans. El and Nina, both being half-bloods, are able to defeat the Onyx Knights for this reason.
