King Piece

Diehauser revealing the King Piece's existence to the Underworld

**King Pieces** are rare Evil Pieces, created in the early days of the Rating Games' existence. Originally created by Ajuka Beelzebub, they were judged too dangerous due to the potential for rogue Devils to abuse them, with their production stopped early on.

## Summary

Created in the early days of the Rating Games' existence by Ajuka Beelzebub, they were judged too dangerous due to the possibility of devils who had malicious intentions towards the government, and could even harm the government, as their production was stopped early on and only Ajuka Beelzebub knows the specifics on how to create them. Despite that, 9 King Pieces were created and seized by the Great King Faction when they took control of the Rating Games. Due to the Rating Games being tied together with politics and economics, the Old Devils of the Great King Faction sought to manipulate the Rating Games form behind the scenes in order to increase their own influence and generate more money, by fixing matches by bestowing certain Pure-blooded Devils from the 72 Pillars such as Roygun Belphegor and Bedeze Abaddon with King Pieces and using bribery to obtain the commercial rights for the popularity obtained by competing in Rating Games. The reason why the top ranked Rating Game contestants don’t have much change in rank is due to Old Devils who are secretly controlling things in order to reap the benefits of the matches, managing the tug-of-war state so that there perfect adjustments to balance it out in order to generate a lot of money.

Despite the fact that the production of the King Piece had been discontinued early on and the Old Devils doing their best to ensure that it's existence was kept an absolute secret, rumors about it's existence spread across the Underworld, with Azazel hearing about them. Cleria Belial, who took a interest in the rumors was able to confirm the King Pieces existence, as the Old Devils had her killed and covered it up, blaming her death on the fact that she had entered into a romantic relationship with the human exorcist Masaomi Yaegaki.

In Volume 17, Cleria's cousin, the current Rating Game Champion; Diehauser Belial, defected to Qlippoth in order to investigate the true reason for Cleria's death, as he believed that it was impossible for Cleria to make a mistake. After learning of the King Piece's existence and the corruption of the Rating Games, he set about to expose the Old Devils who were responsible for Cleria's death and the corruption of the Rating Games, which he enjoyed. He was able to retrieve 2 King Pieces and keep them as future proof.

In Volume 19, Diehauser had a Rating Game against Riser Phenex, during which he revealed the existence of the King Piece to Riser, kidnapping him and his sister Ravel in order to call out Ajuka Beelzebub. They discussed the existence of the King Piece as Diehauser entrusted the Phenex siblings to Ajuka as well as one of the King Pieces he possessed.

In Volume 20, Ajuka revealed the existence of the King Piece to Team DxD, due to the Champion's affiliation to Qlippoth and the matter of the Phenex siblings. During Team DxD's attack on Qlippoth-controlled Agreas, the Champion hacked into the TV stations to broadcast his message out to the entire Underworld, as he revealed the King Piece's existence and the Old Devils corruption of the Rating Games.

In Volume 21, Bedeze Abaddon, who possessed one of the King Pieces, attacked the Bael castle along with his peerage in a attempt to take down the Heads of the Great King Faction, in order to cover up his own involvement in the corruption of the Rating Games and pin the entire blame on the Great King Faction. During Bedeze's fight against Sairaorg Bael, Bedeze offered Sairaorg a King Piece if he stepped aside, but Sairaorg refused as he stated that he wouldn't discard the way he lived until now and defeated Bedeze. Bedeze was taken into custody as another owner of a King Piece, Roygun Belphegor, helped Sairaorg supress the riots happening in the Bael territory.

In Volume 22, it is revealed that those involved in the King Piece scandal were dismissed from their posts and Ajuka prosecuted their mistakes strongly and has been capturing them and revealing the crimes they committed. Many people with authority lost their place and were forced to resign their posts due to the incident as it greatly affected the political world, the business community, the human world, and many other departments.

In Volume 23, it is revealed that the function of the King Piece had been suspended and all of those that had used it to climb the Rating Games had lost all of their privileges, such as Roygun Belphegor, who had her status as the second ranked Rating Game player revoked as her and her Clan's status as Ultimate-class Devils was removed, reducing them to High-class Devils.

## Abilities

The characteristic of the King Piece is power enhancement, as it can strengthen the user by several folds. The strengthening is possible on a magnitude of 10 or 100, as it can elevate a High-class Devil into power that is comparable to Ultimate-class and even strengthening some users to Satan-class powers. All of it's users were capable of being the top Rating Game players, reaching the Top 10 Rating Game players.

While using the King Piece, Bedeze Abaddon was capable of using his strengthened Hole ability to completely overwhelm Genshirou Saji, who was using his Malebolge Vritra Promotion, which has power equal to that of a Dragon King. Bedeze was also capable of overwhelming Sairaorg Bael, who was using his Regulus Rey Leather Rex armor.

While using the King Piece, Roygun had strength comparable to that of Grayfia Lucifuge, who is reknown as the Ultimate Queen and contender for the position of Satan Leviathan and Serafall Leviathan, who is reknown as the strongest female Devil in the Underworld.

### Weakness

If the King Piece is used by someone who is already too strong, or if it is used by someone who has a special ability, an overload may occur as in the worst case, it would endanger their lives.

## Trivia

* After the events of Volume 21, Ajuka succeeded in retrieving all of the King Pieces.
