Perv Asshat

Perv Asshat was the fiancé of Rose Oriana and member of the Cult of Diablos, his real name is Doem ketsuhat.

Raphael Oriana
Perv brainwashed the king to become his puppet in taking over the Oriana Kingdom. He prepared to have Raphael assassinate King 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 costed him 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 conspirators in taking over the Oriana Kingdom. She helped Perv in brainwashing 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
On the other hand, Perv was terrified of Shadow after seeing just how truly deadly he really was. 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.
