Perv Asshat

Perv Asshat (ドエム・ケツハット) was the Oriana Kingdom's Royal Chancellor and Rose's ex-fiancée. He was secretly a member of the Cult of Diablos who sought to become the 12th seat of the Round Knights through seizing the kingdom. After Rose uncovered and exposed his crimes, Mordred beheaded him after his incompetency leaked the Cult's existence to the kingdom.

Appearance
Perv was a handsome man who appeared to be in his thirties with brown facial hair. He donned a red noble suit with yellow outlining and white slacks. In the Anime and Manga, his hair was long enough to be tied into a ponytail.

Personality
Perv was a treacherous schemer with a manipulative nature, having no loyalty to anyone but himself. He was almost willing to use anyone around him as pawns to further his ambitions and would switch sides if it meant benefiting to suits his agenda as he was willing to do anything necessary and wouldn't stop at anything to achieve his goals. This included manipulating or killing anyone especially Midgar and their princess. However, he was self aware of his surroundings and cautious enough to know when it'll work against him. This was demonstrated after he realized Beatrix's presence and knew it was a terrible idea if he were to off either her or the princess.

After the Bushin Festival Tournament, he became paranoid after witnessing Shadow and his organization's prowess firsthand. Because of the aforementioned, he doubted the Cult's abilities in maintaining their status quo and crushing their biggest opposition. His paranoia was caused by the consequences of failure after gaining support from the 9th Seat of the Round Knights and feared that further more will result in his death. This was proven true when he tried to improvise his missing engagement ring at the wedding only for Rose to present the ring Cid stole and expose him. This resulted in Mordred being forced to behead him to prevent further intel the Cult had from being leaked, even having him glaringly remark his incompetence.

Powers & Abilities
As Duke and Royal Chancellor, he held enormous political power and influence only second to the king. Although an advisor, he was merely a representative and spokesman for the kingdom. He possessed some physical strength and magical power equal to the "Second Children" of the Cult albeit the weakest of them all.

Swordsmanship
During the Bushin Festival Tournament, Perv claimed to Iris that his swordsmanship were "decent" and acknowledged that he was no match for her, Beatrix, Shadow, or even Rose. This was further demonstrated when Rose overpowered him during their crashed wedding. Initially believing to be evenly matched, the former princess rebuked that his sloppy swordsmanship wouldn't be able to take anyone down before defeating him with ease.

Master Manipulator
Despite his mediocre sword prowess, he more than made up for his manipulative nature and political influence within the Cult. This was demonstrated when he attracted Reina's support in conspiring against her kingdom and further more from Mordred in elevating him to 12th seat conditionally. Despite performing these feats, he garnered suspicion from Iris and Beatrix albeit inadvertently. His mediocre fighting prowess and high intellect appears to be an parallel to Gamma albeit, he did no had the same physical strength nor intellectual versatilely as the elven.
