The episode 7 of The Insipid Prince’s Furtive Grab for the Throne starts with Arnold Reks Adler operating far from the imperial court under his secret identity, Silver, one of the five SS-class adventurers. His quiet mission is interrupted when Sebastian informs him that General Dominik has died. Arnold immediately suspects assassination, but with few details available and little apparent interest in investigating the killing, he chooses to finish his current request before returning to the capital.
At the Adventurer’s Guild in Wirth, Silver completes his latest job by defeating a King Minotaur alone. The guild staff are thrilled to have one of the continent’s most powerful adventurers at their branch, while Silver casually gives them alcohol as a gift. His reputation as an overwhelmingly capable adventurer is already firmly established, yet Arnold has no intention of connecting that reputation to the supposedly useless seventh prince.
Back at the imperial castle, Arnold meets his twin brother, Leonard Reks Adler, and learns that the struggle for the throne is becoming increasingly dangerous. A powerful figure who supported Leonard has died, making it clear that rival factions are willing to eliminate anyone standing in their way. Arnold admits that he cannot remain outside the succession conflict forever. If Leonard refuses to fight, both brothers and their mother could eventually be killed.
Arnold therefore agrees to support Leonard’s claim to the throne, but he wants his brother to build enough strength that hostile factions cannot easily threaten him. Leonard plans to search for allies, even though most influential nobles and ministers are already aligned with the first three imperial princes. Arnold believes Leonard is actually better suited to become emperor, while Leonard jokes that he would rather spend his life enjoying luxury with a beautiful wife. His plan is simple: Leonard becomes emperor, while Arnold gets to live comfortably away from political responsibility.
The brothers then discuss Arnold’s greatest hidden advantage: Silver. Revealing that Arnold is an SS-class adventurer could dramatically increase Leonard’s influence, but Arnold refuses to expose his identity yet. His use of ancient magic is another reason for secrecy. Royalty has treated ancient magic as taboo ever since Arnold’s great-grandfather became obsessed with it, and publicly revealing that Arnold possesses such power could damage Leonard’s political position.
Instead, Arnold decides to use Silver indirectly. Sebastian reveals that only one major ducal family remains outside the current succession factions: the Kleinert household. The family has been struggling with a serious monster problem in its territory, leaving them unable to resolve the crisis. Arnold sees an opportunity. Leonard can appear to have helped the Kleinerts by arranging for Silver to deal with their monster problem, potentially earning their gratitude and support without exposing the connection between Arnold and Silver.
There is one complication. Duke Kleinert’s daughter, Finne Von Kleinert, is famous for her beauty and is known as the Blau Mowe. Sebastian warns Arnold not to get distracted by her, prompting the prince to complain about his ever-present lectures.
Arnold first visits the Kleinert mansion as Silver, but the plan immediately goes wrong. The gatekeeper refuses to believe that the legendary SS-class adventurer has arrived, dismisses his claim and sends him away. Silver could easily force the issue, but Arnold instead returns to the capital with a different plan.
Five days later, Arnold himself arrives in the Kleinert domain. The duke is confused by the prince’s unexpected visit, but Arnold quickly makes the situation uncomfortable. He claims he has come to discuss compensation and reminds Duke Kleinert that Leonard supposedly sent an SS-class adventurer to help his territory. The duke insists he knows nothing about it, creating exactly the kind of crisis Arnold intended to manufacture.
Arnold and Sebastian soon discover that the duke truly was unaware of Silver’s visit. Someone from the household had rejected Silver before the duke ever learned about the request. Arnold uses that mistake to pressure the family, arguing that Leonard took the trouble to deploy an SS-class adventurer while fighting for the throne.
When the duke realizes what happened, his anger turns toward his own son, who admits that he rejected Silver because he assumed the adventurer was an impostor. The duke is horrified that his household allowed such a valuable opportunity to slip away. He even offers his own life as compensation, but Arnold refuses to accept either the duke’s head or his son’s.
Instead, Arnold asks for something far more valuable. He demands that the Kleinert family offer something important enough to compensate both their household and Leonard’s interests. Finne immediately steps forward, offering herself in exchange for forgiveness. Her father and brother desperately try to stop her from sacrificing herself, while Finne insists that she bears responsibility because she personally saw Silver arrive and failed to prevent the situation.
Sebastian advises Arnold to calm the situation, explaining that the duke’s family is already willing to go to extreme lengths. Arnold realizes that simply crushing the Kleinerts would damage Leonard’s reputation rather than strengthen it. Leonard’s greatest political advantage is his ability to forgive and attract people, so Arnold chooses to exploit that image instead of destroying it.
Arnold ultimately gives the family another chance. Finne later encounters Silver and apologizes for the insult. She admits that the Kleinert family failed to recognize the importance of his arrival and asks him to accept the monster extermination request again. Silver agrees, but only after demanding proof that the Kleinerts will genuinely support Leonard.
Finne cannot make that promise on her father’s behalf, but Arnold, still disguised as Silver, refuses to proceed without some form of commitment. Finne then turns to Prince Arnold himself. Despite his reputation as the insipid prince, Arnold bows his head and personally begs Silver to save the people suffering from the monsters.
Silver finally accepts. Finne is deeply surprised by Arnold’s behavior. She had expected a frightening royal figure, but instead sees someone willing to sacrifice his pride for his people. Arnold privately admits that her interpretation is wrong: he lowered his head primarily because doing so serves his own interests and protects the future he wants. Still, he allows Finne to believe that there is more kindness beneath his careless exterior.
The episode then shifts toward the actual monster crisis. The Kleinert territory is being overwhelmed by slimes, with a massive Mother Slime continually producing more creatures. A party containing two A-class and four B-class adventurers has already tried to solve the problem, but their attacks have failed to destroy the source. They can control the damage only temporarily because the Mother Slime keeps reproducing.
Silver arrives and meets Abel, the leader of the adventurer party. Abel initially refuses to simply step aside because Silver is an SS-class adventurer. His team has already accepted the request, and their pride as adventurers prevents them from immediately surrendering the job to someone else.
Silver respects their position and asks whether they can actually defeat the Mother Slime. Abel admits that they cannot. Their offensive power is insufficient to deliver a fatal blow, forcing them to retreat repeatedly. Rather than belittling them, Silver praises their efforts. He recognizes that their attacks prevented the monster crisis from spreading even further and assures them that their work matters. Abel and the others are stunned to receive genuine praise from someone of Silver’s legendary status.
With the other adventurers stepping aside, Silver finally confronts the true source of the crisis. Instead of relying on an ordinary weapon or technique, he begins using ancient magic. The scale of the spell reveals just how far beyond ordinary adventurers Silver really is. He invokes the power of the heavens and unleashes Execution Prominence, a devastating attack that wipes out the Mother Slime and the surrounding slimes in one overwhelming strike.
The monster crisis is solved instantly. Yet Silver has no interest in becoming a celebrated hero. When the others praise him for saving the duke’s territory, he simply leaves the recognition to them. His real objective has always been larger than monster extermination: Arnold is quietly manipulating events to strengthen Leonard’s faction and secure the political alliances his brother needs to survive the imperial succession battle.
The episode ends with Arnold returning to his private space after completing another piece of his brother’s political strategy. His secret identity remains intact, his ancient magic remains hidden, and the Kleinerts now have every reason to reconsider where they stand.
But just as Arnold believes the situation is under control, Finne suddenly encounters him and realizes the truth about the man behind the Silver identity. That final moment puts Arnold’s carefully protected secret in immediate danger and sets up a much more personal complication for his growing political scheme.
The Insipid Prince’s Furtive Grab for the Throne Episode 7 episode delivers a strong mix of political strategy, character development, and high-level action, with Arnold once again proving that his “insipid prince” reputation hides a remarkably calculated mind. His efforts to secure the Kleinert family’s support give the story greater political weight, while his Silver identity allows him to solve the monster crisis without exposing his true abilities. The battle against the Mother Slime provides the episode’s biggest action highlight, especially when Arnold unleashes his overwhelming ancient magic. At the same time, his interactions with Finne add an interesting emotional layer, as she begins to see a side of Arnold that conflicts with his public reputation. The episode ends on a compelling note as Arnold’s carefully guarded secret faces a new threat, making this a particularly important chapter for both his political ambitions and his growing relationships.
