In a galaxy where nobles rule with arrogance and the gap between social classes is vast, John Ouzos is a mercenary who knows exactly where he stands. Short, portly, and unassuming, John pilots a ramshackle ship called the Patchwork, taking whatever jobs come his way. He does not fight for glory or honor. He fights to pay off his father’s farm debts and to fund his own hobbies, which include anime and light novels. His greatest ambition is to be completely ordinary. In his mind, trouble always follows the protagonist of any story, so he has decided to be neither a hero nor even a notable side character. He is determined to be nothing more than an NPC, a background figure who completes his missions, collects his pay, and vanishes without anyone noticing.

The galaxy John drifts through is vast and dangerous, filled with pirates hiding in asteroid fields, scheming nobles, and the constant threat of war between rival houses. The setting resembles a fantasy guild adventure transposed into space, with mercenaries accepting contracts from guild halls, escorting ships, hunting pirates, and getting caught in the crossfire of conflicts they would rather avoid. John’s work takes him across distant star systems, from planets bleached white by salt to remote archaeological sites and the volatile territories of noble families. The mercenary guild system provides the backbone of his existence, allowing him to accept jobs as long as he is willing to ignore the politics swirling around him.

Despite his unremarkable appearance and his best efforts to remain invisible, John possesses exceptional piloting skills that he cannot fully hide. He is one of the best pilots in the galaxy, a fact that draws unwanted attention. Beautiful, strong, and statuesque women approach him regularly, but their interest is never romantic. They want to work with him, duel him, or challenge him because they recognize his talent. A fellow mercenary grows furious at what she sees as him hiding his true abilities behind lazy excuses. A sentient spaceship becomes determined to have him as her pilot so she can escape her immature current partner. An old classmate who has become a famous racer wants him to join her team. Each of these women sees the skill he tries so hard to conceal, and each one pulls him further into the spotlight he despises.

The narrative follows John through a series of episodic adventures, each structured like a guild quest translated into space opera terms. He takes security jobs that turn into murder mysteries, hunts pirates only to find himself blocked by noble territories, and provides piloting services that leave him stranded and betrayed. In one mission, he acts as security for a noble party where a murder occurs, forcing him to help an accomplice escape. In another, he pilots for an archaeologist only to be left for dead while his ship is destroyed. The jobs are varied, but the pattern is consistent: John wants simplicity, and the galaxy refuses to give it to him.

Throughout these adventures, the corrupt nobility of the empire serves as the primary source of his problems. Almost every noble John encounters is arrogant, cruel, or both. They bully him for his commoner status, hire him for dangerous work and refuse to pay, or try to use him as a pawn in their political games. A cartoonishly evil noble girl seems to have stepped out of a villainess story, while disgraced nobles turned pirates hunt him for sport. The empress who rules the galaxy appears to be one of the few decent nobles, though even she is manipulating events from behind the scenes, deliberately appearing less competent than she truly is to lure corrupt nobles into revealing themselves.

As the series progresses, an overarching conspiracy begins to emerge. The encounters that once seemed random start to feel connected, and John finds himself caught in the middle of a brewing noble rebellion. In the third volume, he finally earns enough to pay off his parents' debt, a milestone he has been working toward since the beginning. But rather than retire, he gently rejects their offer to find different work, admitting to himself that mercenary life is what suits him best. Shortly after this achievement, his ship is destroyed and he is left for dead, a turning point that forces him to rebuild from nearly nothing. He acquires a new ship, an improved version of his old Patchwork with better radar and more space for storing his manga collection, but the loss is a reminder that even his best efforts cannot keep him safe.

The rebellion finally erupts in the fourth volume, plunging the galaxy into martial law. Mercenaries are called to fight for the empire, and John has no choice but to participate. The empress, it turns out, has been orchestrating events to expose the worst of the nobles, using double agents and financial penalties to dismantle the conspiracy from within. Once the rebellion is crushed, the disgraced nobles who survive turn to piracy, giving John a new wave of contracts as he hunts them down across the galaxy. Even as he does this work, the attention he receives only grows. A tsundere noble girl named Fialka remains a persistent presence in his life, alternating between harsh words and reluctant admiration. His childhood friend Scuna misinterprets his actions at every turn, adding comedic misunderstandings to an already complicated existence.

Throughout all of this, John remains stubbornly committed to his NPC philosophy. When others try to promote him, he refuses. When they praise his skills, he deflects. When they ask why he holds himself back, he explains that rising in the ranks would mean more official business, more run-ins with snobby nobles, and far more danger than he wants to face. His emotional state rarely shifts from a default of flat acceptance, a defense mechanism that may stem from a traumatic past that is only hinted at. He does not seek excitement, but excitement continues to find him. He does not want to be a protagonist, but the women who surround him, the nobles who hate him, and the conspiracy that is slowly revealing itself all suggest that the universe has other plans.
