Perv Asshat/Chronology

Background
Doem was the second adopted son of Duke Ketsuhat who joined the Cult of Diablos and through dubious means, he quickly became Oriana's Royal Chancellor by committing illegal acts to obtain the position. He masqueraded himself as a good-willed politician with a good reputation in the public eye who were unaware of his criminal activities.

Upon learning the King's treason after he refused to hold his end of their agreement and severed ties by allying with the Kingdom of Midgar, the Cult ordered Doem to brainwash him as their puppet by drugging him with his wife's help. Before he was brainwashed, Raphael was able to send his daughter Rose to Midgar under asylum. It was then that the Cult decided to usurp the Kingdom through the Second Child.

Doem persuaded and curried favor from the 9th seat Knights of Rounds, Mordred and his faction to support his elevation into taking the vacant 12th seat. Under the condition that his mission was successful, Mordred agreed in helping in exchange for his backing support in the Cult's upcoming internal power struggle.

Before Raphael became the their puppet, he did one final act; he took possession of the "Ring of Succession", which was the key to the "Black Rose", and recorded his last will in the ring alongside the evidence of Doem and the Cult's crimes. He also altered the ring ownership over to his daughter and it was through marrying her that the ring can allow control beyond it's user. After finished recording, he hid the ring within his kingdom's First Fort.

While Mordred tracked the ring's location, Doem visited the Royal Capital of Midgar to retrieve Rose Oriana under the pretense of their engagement after he brainwashed the King.

Bushin Festival Tournament
Doem alongside his subordinates met Rose and smirked at her after presenting to her, her brainwashed father. Rose suddenly drew her sword and attacked before his subordinates called the guards to apprehend her. Framed as a criminal, Rose fled into hiding as Doem threaten her to surrender before the festival's end or he'll order her father to kill King Klaus Midgar. He also noticed that Rose showed symptoms of demon possession and took the opportunity to use her for the cult's experiments. Despite having jurisdiction, The Chancellor and his collaborators dissuaded Midgar from investigating on the matter and personally went on to handle it themselves.

Doem and his Puppet King later had a meeting with Princess Iris to discuss the security plan for the Bushin Festival, but didn't believed that there was a need for more. When Iris noted on that his condition was better than the report she received, he clarified that the report exaggerated and assumed that the kingdom has gone paranoid from Alexia's kidnapping. He heard that she personally went to look for her and decided follow the same and to avoid external problems. He then added that he'll take care of every businesses for the negotiations and restructure her order before attending the Festival. He lastly sympathized with her worries and assured her that Oriana will not cause trouble to her kingdom.

He later met the princess at the main event where she harbored suspicion. They discussed about Rose's predicament when he assured her return when she calms down before explaining that Raphael is well enough to attend the festival tomorrow. Iris informed him that his father will also be attending tomorrow to spectate after he apologized that the provided security was assembled in vain. The two watched the tournament when the match between Annerose Nichtsehen and Mundane Mann commenced where Iris believed Mundane will win despite the Swordswoman's favor from The Chancellor and crowd. Mundane pulled the upset and won before he complimented her observation. After the match, he had his men search the dark horse's background and believed that he's a denizen of the Lawless City who'll pose a threat to his plans. He lastly dismissed the idea of a possible connection to Shadow Garden and doubted that they have a motive at the Festival.

Before the finals of the tournament and meeting the King, Doem drugged Raphael once more and ordered his men to cover its odor sweet with perfume. He waited for Rose to arrive at the tournament from the threats he made believing that even if she didn't come, he would order his puppet king kill King Klaus Midgar and start a war resulting in Oriana's annihilation and loss of status. He didn't ponder as the Cult's plans to install a puppet leader in Midgar Kingdom were already underway. Worried about Shadow Garden's activities and possible collaboration with Rose, he prepared to increase the Cult's forces around the venue.

Upon arriving for the finals, he along with Raphael met up with Iris once more to become wary of Beatrix when she noticed something off about them. He thought of offing Iris if she were to obstruct him but decided to against it when Beatrix's presence became known that it'll be a bad idea. He was on high alert about Mundane due to his close to non-existent background, which meant to him that he covered his tracks and had an objective. Wary of him, he anxiously decided to spectate and predict outcome of the match between Iris and Mundane.

He watched Iris' match against Mundane and was shocked that she was taken down in one strike. It was after that Rose suddenly arrived to kill her father before attempting to take her own life. Outraged that he lost his puppet, he ordered his knights to apprehend her when Mundane intervene to reveal himself as Shadow.

Novel/Manga
Doem sent his men after a fleeing Rose before they were slaughtered by Shadow. Realizing the fruitless attempt, he witnessed both Iris and the Goddess confront the leader of Shadow Garden. The confrontation occurred within the venue with the two swordswoman put on a valiant effort. Despite their joint efforts, both the spectators and the chancellor were shocked to see the strongest knights imaginable with ease by Shadow before he disappeared.

Anime
Doem tried to apprehend her but had no means to when all of his men were killed by Shadow Garden members led by Beta. By the time Beatrix jumped into the fray, he saw an opportunity to escape back to Oriana without stopping at the embassy and left Raphael's corpse to his political archenemy, Marquess Grant. During his siege within the kingdom, Grant was the leader of the anti-chancellor faction who sought to prevent his usurpation.

Returning to Oriana, Doem was reprimanded by Mordred after hearing the report of his failed operation in securing Rose due to Shadow's intervention and conveyed his disappointment. Disgruntled by his failure, he begged for his forgiveness before informing him of their leverage over the kingdom and as long as the Cult holds the royal family, Rose won't be able to stay hidden. Plus Oriana's situation is already in chaos with the loss of their king, Perv is sure that Rose can't ignore it and will come back. Mordred said hopefully so and ended his conversation by telling Doem not to disappoint him again.

Red Moon Incident
Following Rose's escape due to Shadow's interference for ruining his plans during the Bushin Festival which resulted in losing a puppet king to control the kingdom, Doem decided to think about changing his original plans while he's still sending all of the Cult's troops to search for the location where the king had hidden the ring.

According to Beta's report, Doem was struggling to maintain Oriana's internal affairs after Princess Rose Oriana caused an international incident by publicly murdered the King Raphael Oriana in broad daylight. Leaving with neither a monarch or successor, the nation descended into a civil war over the throne.

Oriana's "Black Rose" Civil War Wedding
While still in control of the kingdom's affairs, Doem received word that the ring has been found in a ruined site near Fort First but was unable to retrieve it as it was sealed and only the royal family could break it. Thus, he sent Kouadoi to lead a group of 40 First Children with 3 Named to the ruins along with Queen Reina to retrieve the "Ring of Succession".

However, the Cult's group had received a surprise attack by Shadow Garden team led by 559 after they successfully acquired the ring. Reina was nearly killed by 559's attack when one of the other numbers which happened to be Rose intervened. This instance allowed Kouadoi to see an opportunity to hold Rose and Reina hostage during their dispute, whereupon 559 ignored the threat and branded Rose a traitor to Shadow Garden. Kouadoi ordered his men to send Rose and her mother to Doem while he engaged in battle with the remaining numbers and called for reinforcements.

Anticipating Rose's return, Doem threatened Rose that her mother will be killed if she doesn't comply with his orders. Reina being her mother and only family left, Rose was forced to comply with Doem's orders under the threat of her mother's safety while unaware that she conspired with him. Despite having managed to get the ring, Doem realized that the ring has been altered its ownership through Rose and that only she could activate it.

Doem was forced to alter his plans of taking over the kingdom by marrying Rose in order to win the civil war so that he gain ownership of the ring and finally so he could succeed in completing his mission. In doing so, this would've ensured his position as 12th seat of the Round Knights and conquering Oriana directly as the Cult's puppet state, as well as handing Rose over to the Cult for their nefarious experimentation after extracting intel from her.

Since news of Shadow Garden's raid at Fort First had reached Doem, he had tightened the security around the capital to ensure that Shadow Garden couldn't infiltrate and take any action that would jeopardize his plans. Unbeknownst to him however, the incident had also reached Shadow who became confuse upon learning the invitation announcement regarding Rose's marriage with the Chancellor. Set on stopping her from marrying, Shadow infiltrated Oriana as an unassuming boy.

While Doem was surveying the palace with his entourage, he coincidentally met Miss Shiron who was an invited guest set to perform at their venue. However, she was with an uninvited young boy who claimed to be an apprentice. Suspicious of his presence coupled with the incident at Fort First, Doem stopped the two under the pretext of changing the castle's premise rules and that her student might be an intruder. To confirm his suspicion, Doem tried testing the alleged apprentices of his legitimacy in front of a stage full of nobles. Unexpectedly, Doem was too touched by his performance after playing The Moonlight Sonata much to his shocked and joy that he tried asking the apprentices' name. But, the apprentices refused to answer and ran off with Shiron, unaware that the Ring of Succession has been taken by an apprentice who is none other than Cid Kagenō which he thinks that the ring is an engagement ring and considers pawning it.

After the performance, Doem returned to Rose's room and barged into her room after he heard that she was talking to someone. When he entered her room, he saw no one in the room but Rose. Doem confronted Rose about her current situation and threatens that her mother's safety was dependent on her cooperation with him. Unbeknownst to him however, Cid overheard everything of their conversation while hiding outside the room and learnt that she was coerced into the marriage.

Later in the night, Doem went into Reina's room and told her that once his business with Rose is over, he would publish their relationship in front of the kingdom's people. While they became intimate, Cid in his Shadow persona alongside Rose witnessed everything and concluded that Reina was never in danger and was conspiring in the kingdom's usurpation while having an affair with The Chancellor.

Shortly after witnessing everything, Cid tried to reignite Rose's resolve in saving her kingdom unknowingly that the engagement ring that Cid pocketed from her fiancé has been left in Rose's room. Unbeknownst to Cid however, the engagement ring he left was the Ring of Succession which Rose believed to be the ring of the person she cared about. After hearing Cid's motivational speech about trust as a sign of both affection and devotion, Rose became set on saving her kingdom once more.

Before the upcoming wedding day, Doem was still worried about security in the capital to the point where he had to carry out a check on the defensive perimeter from the reports of Cult agents disguised as guards to make sure there was no disturbance and keep a watchful eye on Shadow Garden's movements that might be currently plotting something within the kingdom. With a very strict guard system in place, Doem assured himself that once he married Rose, he'll snuff out intel from her and be promoted to 12th seat after successfully seizing the kingdom. Despite the elevation, he was well aware that he had the weakest track record of his achievements to the point that he'll have to play along with Mordred to gain more political power within the Round Knights and whatever faction is in control.

Upon opening the case containing the Ring of Succession, Doem discovered that the ring was gone to the point where he panics that he has made sure the ring is in the box case still which kept in his pocket until it never leaves him and the only person who knows the Ring is Queen Reina, but Doem knew that he had no motive to steal the ring. Doem even thought that this was Shadow Garden's work, but that doesn’t make any sense since they would’ve just killed him if they have the opportunity.

Leaving aside his thought, Doem realizes that this act must have been caused by an inside job from the work of Mordred's opposing faction with their wicked motives and want to ruin Doem, which got him played by setting a cruel trap for him by stealing the ring and leaving the box. If his assumptions are correct, then Doem knows that the power struggle must already be underway which makes his promotion to become the Rounds is vanish and if Mordred finds out about his blunder, he would definitely be killed for sure.

Therefore, Doem seeks to find the ring himself without having to use any Cult personnel to do so because their loyalties lies with Mordred. Fortunately, Doem still has some time left before he actually needs the ring and he can probably buy himself time for three days before the handoff. At the time Doem wanted to do a search for the Ring of Succession, Mordred spoke to him telepathically by telling him that everything was setup for him to be promoted once everything was over and not to disappoint him. Without knowing what the future holds, he anxiously continued on with the wedding.

At the wedding, Rose rebuked both him and the wedding while presenting the Ring of Succession. The ring activated accordingly and Raphael Oriana's last will was played to the everyone in attendance. In his last will, he exposed Doem as the main culprit in his manipulation especially implying his wife's involvement and the Cult's conspiracy to seize control of the kingdom in his crimes. He lastly entrusted the kingdom to his daughter and implored the citizens to believe in her before the recording finished. Realizing his plans have completely and utterly failed, Doem in an act of desperation tried to order for her now ex-fiancé's apprehension but was given nothing but glares in response.

Now confronted by the princess, an enraged Doem attacked Rose and their final skirmish commenced. Initially thought to be evenly matched, Rose overpowered him and avoided fatally wounding him to confess his sins. Before could finish his sentence, he was suddenly beheaded by a fed up Mordred before cutting down his collaborator.

Legacy
In the events of his death, Princess Rose and Shadow Garden freed Oriana from the Cult's control and became more aware of their existence than Midgar. Although Perv was dead now, his failures resulting in the exposure of the Cult's activities within Oriana Kingdom would have consequences.

With their existence threatening to be exposed, the Cult would use their connections within the Holy Church to branded Oriana Kingdom as a heretic state. In doing so, international support for the kingdom will be cut off and eventually allow neighboring countries to invade Oriana, whilst preparing to initiate a "holy war" to destroy the nation and thus cover up their past actions.

Alpha demonstrated that the Cult will not die as long as people believes in them and by distinguishing the Church from the Cult, the Cult will become the world's common enemy. The elven assured her as long as the queen is determined, Shadow Garden will not betray her before being cut off by 664 & 665.
