Demon Lord Knights or Demon King Knights (デーモンキングナイト, Dēmonkingunaito) are knights who have powers nearly equal to the Trinity Seven. They were chosen willingly to undergo a forbidden ritual which turned them into knights, removing their human persona. Unlike all the previous Demon Lords, the Demon Lord Knights do not possess souls. They currently reside in Demise World.
Originally, they were all human mages, but they undergone a ritual which requires four talented mages to do so. With each one possess unique ability to their own, in their former human lives. After becoming a Demon Lord Knights, the summoner gave them two tasks to complete. The first to eliminate Anastasia-L whom called the 'The traitors Saint' because she sealed Demise. The second task is to revive Demise. Having faith in them doing so. However as time passed each assassin failed to do so, and befriended Ana.
At some point they built a massive crystal which shows events that is happening, as well as meeting Altana Magnus. Unknown to them that she was performing experiments. Seeking power and revenge against Ana, the Arbitrator gave Pandora a forbidden weapon.
Unfortunately, all the Knights along with Altana, Lilith and Ana have been trapped in the school. Fortunately because of Lilith and Ana possess the same Thema, they were able to escape the trapped dimension by using their Last Crest.
However, a cost have been paid at both parties, for the Knights they became "deceased" and how many years would have passed they won't age, remaining at their youth. But are still alive. Pandora as well has the power to summon all four of them at any time she wishes. They chose to remain in Demise World and protect it, in case something happened. Altana has stayed as well but she sealed their memories of them meeting her.
