Perv Asshat

Perv Asshat (ドエム・ケツハット) was the royal chancellor of the Oriana Kingdom and Rose's ex-fiancée. In actuality, however, he was a Cult of Diablos member who sought to become a Knight of Rounds by seizing the kingdom and handing over Rose to be experimented on, only to be killed by his superior, Mordred, after his failures led to the Cult getting exposed.

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

Personality
Perv was a treacherous schemer with a manipulative nature, having no loyalty to anyone but himself. He was willing to use almost everyone around him as pawns to further his ambitions and would switch sides if it meant benefiting 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 cautious enough to know when it'll work against him when he realized Beatrix's presence and knew it was a going to be a terrible idea if he were to off the princess.

After the Bushin Festival event, he became paranoid after witnessing Shadow and his organization's prowess firsthand. His paranoia was due to the consequences of failure after he garnered support from the 9th seat of Rounds and possibility of being utterly foiled and killed by the mysterious figure and his organization. Because of the aforementioned, he doubted the Cult's abilities in maintaining the status quo and crushing their biggest opposition. This was proven true when he tried improvising 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.

Powers & Abilities
As Duke and Royal Chancellor, he held enormous political power and influence, 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, Perv claimed to Iris Midgar that his sword skills are "decent". Overall. he appears to be fully aware of his limits, acknowledging that he is no match for her, Beatrix, Shadow, Mordred, or even Rose. This was further demonstrated when Rose overpowered him in their crashed wedding.

High Intellect
Despite his mediocre swordsmanship, he more than made up for his political prowess within the Cult. This was demonstrated by his manipulative scheming when he attracted Oriana's queen, Reina's support in conspiring against her kingdom and support from Mordred in elevating him to 12th seat. 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.
