Perv Asshat

Perv Asshat (ドエム・ケツハット) was a duke from the Oriana Kingdom who served as the country's chancellor. He was also Rose Oriana's ex-fiancée. In truth, however, he was a member of the Cult of Diablos who sought to become a Knight of Rounds by taking over the kingdom using his puppet king and hand over Rose to the cult for their experiments.

Appearance
Doem looks are quite handsome for a man around thirty.

Personality
One key aspect about Perv is that he is a treacherous schemer with a manipulative nature, having no loyalty at all to anyone, even to his allies. He is willing to use almost everyone around him as pawns to further his ambitions and would switch sides if it suits his agenda. He is willing to do anything necessary and won't stop at anything to achieve his goals, including manipulating or killing anyone.

Background
Learning the Oriana's current king treason for cutting his ties with the cult and building a force to rebel against the cult by allying with the Midgar Kingdom and also sending his daughter to attend their academy in the secret hope to protect her from harm, they decide to brainwash him to become their puppet king by ordering Doem to drug the king considering his action with the help from the Queen Reina.

Doem persuaded and curried favor with the 9th Seat Knight of Rounds, Mordred, and his faction to help him receive a promotion to become a candidate for occupying the Knight Rounds 12th seat if his mission from the cult has been successful. Mordred agreed on helping him, in exchange for Doem's backing support in the cult's upcoming internal power struggle.

Before the king become cult's puppet, he did one final act; he took possession of the "Ring of Succession", which was the key to the "Black Rose", then he recorded his last will in the ring along with all evidence of Doem and cult's crimes. Also, he altered the ring to transfer control over his daughter, and by marrying her is the only way to gain dominion over the ring. After that, the king hid the ring from the cult.

While Mordred searches the ring's hiding place, Doem will be visiting the Royal Capital of Midgar to retrieve Rose Oriana under the pretense of their engagement after the king become his puppet.

God of War Festival
Perv meets Rose and he smiles at her along with his subordinate after he presented her brainwashed father to her. Rose drew her sword and attacked him all sudden, but his subordinate called for some guards to apprehend her. Rose, now framed as a criminal, fled with Perv warning the princess to surrender herself before the festival ended, or he'll order her father to make him kill the king Klaus Midgar. Perv also noticing that Rose showed signs of possession, which means she will become a prime material for the cult's experimentation. So, Perv and his collaborators then dissuaded Midgar's government not to get involved in interfering with Rose's affairs and personally want to handle it themselves.

Perv later meets Iris Midgar at the tournament when she, who is suspicious of Perv, discusses and asks about Rose's predicament but Perv calmly expressed confidence that she will return to him once she calmed down. He explains that his puppet king will be attending the festival tomorrow citing not feeling unwell and apologized that the security that had been prepared was in vain, Iris explains that his father, king Klaus Midgar will be also watching from tomorrow.

Perv and Iris watch the tournament when the match between Annerose Nichtsehen and Mundane Mann. Iris had a feeling that Mundane will possibly win the match, and Mundane wins against Annerose and compliments Iris's observation. After the match was over, Perv had his men search Mundane Mann's background, believing he might be a potential threat to his plans because it will be a problem if he is a denizen of underworld society backed by the Lawless City, even Perv dismisses the idea of Mundane have a connection with Shadow Garden and doubts if they have the motive to take action at the Bushin Festival.

Before going to the final tournament and meet with King Klaus Midgar, Perv drugs King Raphael again and tells his men to cover its odor sweet with a perfume. Perv also waited for Rose to arrive at the tournament because of his threat at her, even if she didn't come he would make his puppet king kill King Klaus and start a war resulting in Oriana Kingdom's annihilation and lose his status. But, Perv doesn't really care because the cult's plans to install a puppet leader in Midgar Kingdom is already underway. Perv is also worried what Shadow Garden may do and that they may be working with Rose, so he preparing to increasing the cult's forces around the tournament arena.

Upon arriving at the tournament for the final match, Perv, along with King Raphael Oriana, met up with Iris once more only to become wary when Beatrix was there, who took notice of something off about the king. Perv also thought of getting rid of Princess Iris if she were to become a hindrance but he decided to forget about it, due to Beatrix's presence which would become even more troublesome if she decided to make a move against him. Even Perv has to be on high alert about Mundane Mann because he never found anything about him no matter how hard Perv searches, which means Mundane is a pro and has some objective. So, Perv decides to wait until the predicament outcome of the match between Iris and Mundane.

He watched Iris's match against Mundane and was shocked that Iris was taken down in one strike. Suddenly, Rose Oriana arrived and she killed her father, along with wounding Perv. Outraged that he lost his puppet, Perv ordered his knights to arrest Rose only for them to be stopped by Mundane Mann who revealed himself to be Shadow. Perv sends his men after Rose as she flees only to see the men he chose have been killed by Shadow and he watches Shadow against Beatrix but she was overwhelmed. Perv witnesses in horror as Shadow's fight ends with Beatrix losing even with Iris Midgar's help, as he bests both of them. Also, Perv witnessed Shadow emitting a large magic vortex from his body in the tournament.

Oriana's "Black Rose" Civil War Wedding Incident
Following Rose's escape and Raphael's death, leaving with neither Oriana Kingdom a monarch or successor, the nation descended into a civil war over the throne. This forced Perv to alter his plans from taking over the country through marrying Rose to directly conquering the kingdom by winning the civil war.

Powers & Abilities
As a Royal Chancellor, he had enormous influence, second to the king. Only by giving effective advice, he was appointed to represent his kingdom and be the spokesman for the king. He possessed some physical strength and magical power on par with the "Second Children" of the Cult of Diablos.

Raphael Oriana
Perv brainwashed the king to become his puppet in taking over the Oriana Kingdom. He prepared to have Raphael assassinate King Klaus Midgar and then used him as a meat shield in case Rose tried to attack him during the Bushin Festival, only to be outraged that the princess killed her father as losing him cost his control over the kingdom. In the end, Perv received his comeuppance when Rose activated the "Ring of Succession" that projected an image of Raphael who exposed all of Perv's crimes.

Reina Oriana
Reina was Perv's lover and part of his collaborators in taking over the Oriana Kingdom when she agreed to help Perv brainwash her husband. While it seems Perv is engaged in a romantic relationship with the queen, it's revealed that Perv saw Reina as nothing more than a useful pawn and implied that he would have her either brainwashed like her husband or killed.

Cid Kagenō / Shadow (Mundane Mann)
Perv catches a glimpse of Cid at the Bushin Festival while in the deluxe suite, but he ignores him. Even when Perv sees him back in the Oriana Kingdom during the civil war, he does not recognize his face and only notices him as the famous pianist and composer Shiron's apprentice making Perv tries to test his skills by playing the piano in front of the nobles as he wants to embarrass him. When he is playing the "Moonlight Sonata" with a passion to the end, Perv was amazed by his performance and wanted to know his name until Perv didn't realize that he was snatching the "Ring of Succession".

On the other hand, Perv was terrified of Shadow after seeing just how truly deadly he was during the Bushin Festival. When he lost the "Ring of Succession", he dismissed the idea that it was Shadow's doing because he believed he would have just easily killed him to get it.

Mordred
Despite Mordred being his direct superior, Perv had no loyalty to him and would have switched allegiances to another Rounds member if it served his goals. Nonetheless, he was shown to be rather fearful of the knight, hiding the fact that he had lost the "Ring of Succession" out of fear of what he would do to him. True enough, Perv died at Mordred's hands after he learned of his failures.

Beatrix
Perv heard about the famed "Goddess of War" and was quite wary of her, concluding that he needed to be careful when she sensed something was off about Raphael despite the chancellor's attempts to hide the king's brainwashing.
