Case Closed: The Scarlet Bullet (2021): Unmasking the True Motives and the Dark Mystery of Makoto Ishihara

The credits roll on Case Closed: The Scarlet Bullet, but instead of the usual thrill of a neatly solved mystery, a lingering sense of unease haunts the audience. Why? Because the film denies us the ultimate catharsis. Instead of delivering a crystal-clear resolution, it leaves us grappling with a terrifying reality: the true nature of the crime may never actually be uncovered.

On the surface, the narrative frames Maiko Shirahato and Osamu Inoue as villains driven by a classic thirst for revenge against the FBI. For Maiko, it is a fiery rage born from watching the bureau brand her father, Makoto Ishihara, as a criminal, ultimately condemning him to die behind bars. For Osamu, it is a deep-seated resentment toward the investigators who ruthlessly buried the full story of the incident 15 years ago—a cover-up that permanently derailed his own family’s legacy.

Yet, scratching just beneath the surface reveals that “revenge” is an overly simplistic label for their elaborate schemes. If pure retaliation against the FBI were their only objective, they could have easily chosen a faster, far more direct method of assassination.

Instead, the duo orchestrates a breathtakingly convoluted master plan. They abduct three corporate CEOs, meticulously echoing the WSG serial kidnappings from a decade and a half ago, all just to finally corner Alan Mackenzie. Why go to such extreme lengths?

In this deep dive, we refuse to dismiss Maiko and Osamu as mere vengeful antagonists. We will dissect what this duo genuinely sought to obliterate. Simultaneously, we will plunge into the murky depths of the original case to ask the ultimate question: Was Makoto Ishihara actually the mastermind he was made out to be?

The short answer? A simple desire for payback didn’t drive Maiko and Osamu. Rather, it was a profound cocktail of “loss and despair” inherited from their fathers, weaponized and aimed at the outside world in two radically different ways.

The ultimate symbol of their hatred was the justice system itself—specifically, the controversial use of plea bargains. The chilling core of The Scarlet Bullet stems from the uncomfortable realization that the system actively prevented anyone from conclusively proving Makoto Ishihara’s guilt or innocence.

Let’s unravel these scattered anomalies to expose the true driving forces behind Maiko and Osamu, and decode the unsettling ambiguity surrounding Makoto Ishihara.

Case Closed: The Scarlet Bullet (2021): Beyond Revenge – What Drove Maiko and Osamu?

The Illusion of a Shared Vendetta Against the FBI

Initially, the narrative spoon-feeds us a straightforward motive: Maiko Shirahato and Osamu Inoue share a burning hatred for the FBI and Alan Mackenzie. Maiko harbors an unforgivable rage after the bureau falsely accused her father, Makoto Ishihara, driving him to die in a prison cell. Osamu simmers with fury because the FBI used a shady plea bargain to close the case, destroying his father’s reputation and life in the process.

However, true vengeance is usually swift. If they only wanted blood, they had countless opportunities to eliminate their targets quietly. When you step back and look at the sheer theatricality of their crime—staging a massive, public reenactment of a 15-year-old kidnapping—framing their actions as simple revenge falls completely apart.

Maiko Shirahato: Desperately Reclaiming Her Father’s Narrative

Maiko’s emotional core is anchored to her father, the man whose life she believes the system unjustly ripped away. But her deepest agony stems from a cruel realization: the alibi she holds onto isn’t strong enough to completely exonerate him.

If an accomplice existed, her precious alibi would crumble instantly. Deep down, she likely understands this fragility. Yet, she fiercely protects it because it is her only lifeline. Therefore, simply assassinating Alan wouldn’t give her peace. Instead, she needed Alan—the man at the epicenter of the tragedy—to look her in the eye and confess that her father’s guilt was never an absolute certainty.

This psychological need explains why she deliberately boards the same Maglev train as Alan during the climax; she intends to extract those exact words from him. Furthermore, the fact that her father refused to betray anyone through a plea bargain served as her ultimate anchor, convincing her of his unwavering moral integrity.

Osamu Inoue: A Toxic Obsession with His Stolen Legacy

Osamu Inoue, on the other hand, is a different breed of dangerous. He doesn’t just hate Alan or the agents involved; he despises the very fact that the 15-year-old case was hastily swept under the rug via a plea bargain. To Osamu, the justice system isn’t a tool for truth—it’s a corrupt machine designed to manufacture convenient narratives.

But his darkness runs much deeper. His true despair doesn’t stem from familial love, but from the realization that the public backlash against his father robbed him of his rightful inheritance: the glamorous, privileged life of a corporate heir.

Look at his endgame. He rejects the quiet safety of the Witness Protection Program. Instead, he orchestrates a catastrophic disaster, wiring the Maglev with explosives to crash it directly into the terminal. This grandiose destruction exposes his true desire: he is lashing out at the society that stripped him of his elite status, attempting to play God and manipulate the world to satisfy his bloated ego.

The Fatal Disconnect: Two Wildly Different Views of Their Fathers

The tragedy of Maiko and Osamu is that while they bonded over the shared trauma of having their lives derailed 15 years ago, they viewed their fathers—the catalysts of their pain—through entirely different lenses.

Maiko grieved for her “father as a human being.” She clung to her flimsy evidence, terrified it wouldn’t be enough, yet fought tooth and nail to restore his personal dignity.

Conversely, Osamu’s grief was incredibly selfish. He mourned “what his father possessed”—the golden ticket of privilege he was owed. His pain wasn’t rooted in failing to protect his family; it was rooted in losing his elite future to the murky shadows of a plea deal. That aimless, toxic anger eventually consumed him, turning him against the world.

This is exactly why Osamu didn’t stop at mere assassination. He craved a “massive reenactment of the past” where he could crown himself the untouchable mastermind. By pulling the strings of a global incident, he artificially reclaimed the omnipotence and power he felt the universe owed him.

Maiko wanted to save a man’s soul. Osamu wanted to conquer the world to soothe his bruised ego. They launched their conspiracy from the exact same starting line, but they were sprinting toward vastly different finish lines.

Case Closed: The Scarlet Bullet (2021): The Makoto Ishihara Mystery – Was He Truly the Mastermind?

The Damning Evidence: Why the FBI Targeted Ishihara

Now, let’s step into the darkness of the original crime. Was Makoto Ishihara actually the mastermind?

Given that he was spotted at the crime scene and his fingerprints heavily coated the murder weapon, it is nearly impossible to claim he was entirely innocent. Working as a sushi chef in Boston gave him organic, unforced access to the wealthy sponsor tier. For the true masterminds, Ishihara was the perfect “useful pawn” to quietly get close to their high-profile targets.

Therefore, instead of being the criminal mastermind, it is highly probable that he was merely a low-level collaborator who got roped into the conspiracy and found himself trapped with no way out.

Glaring Plot Holes: Why Ishihara Couldn’t Be the Shooter

Despite the FBI’s narrative, labeling Ishihara as the decisive “shooter” feels incredibly wrong. Aiding in a kidnapping and executing a victim with a firearm are two entirely different leagues of crime. The chaotic imagery of him desperately chasing a fleeing victim paints the picture of a panicking subordinate, not a cold, calculating mastermind.

Osamu Inoue’s flashback provides a massive clue. In his memory, the suspect arrested 11 years ago is visually depicted holding a gun. This strongly hints that the man who took the plea deal was actually the one pulling the trigger. If that suspect used the closed-door negotiations to dump the ultimate murder charge onto the deceased Ishihara, the entire puzzle suddenly fits together perfectly.

Case Closed: The Scarlet Bullet (2021): The Poisonous Core of Plea Bargaining

The 11-Year-Old Testimony: A Fabricated Truth?

The FBI anchored their entire case against Makoto Ishihara on the testimony provided by the suspect arrested 11 years ago. While plea bargains are powerful tools for breaking complex cases, they are also dangerous mechanisms capable of cementing a highly fabricated, convenient version of the truth.

A cornered criminal has every incentive to lie. By shifting the heaviest charges onto Ishihara—who couldn’t defend himself—the informant secured a lighter sentence. For the FBI, once Ishihara was officially branded the culprit, reopening the investigation would only cause political headaches. Consequently, the harder the justice system worked to process the case, the more the actual truth about Makoto Ishihara faded into obscurity.

The True Meaning Behind Makoto Ishihara’s Silence

The original WSG incident was a massive logistical operation requiring multiple operatives. The FBI undoubtedly knew Ishihara wasn’t acting alone. Following standard American investigative protocols, they absolutely would have offered Ishihara a plea deal to rat out his accomplices in exchange for a lighter sentence.

So, why did Ishihara remain silent until his dying breath?

The most optimistic theory is that he was completely innocent. While comforting, the reality of the criminal underworld is rarely that simple.

A more realistic scenario is that he was merely a low-level driver or lookout. He might not have even known the true identities of the masterminds, making it impossible for him to provide a valuable confession. In this case, his silence perfectly aligns with the theory that he wasn’t the ringleader.

Alternatively, Ishihara might have harbored a profound, cultural rejection of the plea bargain system itself. Even though he worked in America, his moral compass was forged in Japan. If his core values fundamentally rejected the cowardly act of “selling out a peer to save your own skin,” his stubborn silence makes complete narrative sense. (Positioning Ishihara as a Japanese immigrant adds a brilliant layer of cultural friction to the story).

Finally, we cannot ignore the threat of cartel retaliation. Even with the Witness Protection Program, Ishihara likely realized that snitching could put a permanent target on his family’s back. Remaining silent was perhaps his only way to protect them.

Ultimately, this ambiguous silence fueled Maiko Shirahato’s crusade. For her, the idea that “he refused the deal because he was an innocent man of honor” became an absolute, unshakeable truth.

Case Closed: The Scarlet Bullet (2021): How the Modern Crime Exposes the Past

A Distorted Mirror: Reenacting a Flawed Conspiracy

The modern-day abduction of three corporate titans required flawless timing and a strict division of labor. This complexity serves as a giant neon sign pointing to the past, suggesting that the incident 15 years ago was far too intricate to be pinned entirely on one man like Makoto Ishihara.

Look at how the modern crime was structured: Osamu scouted Maiko online, weaponized her grief, and used her as a pawn. This terrifyingly mirrors the high probability that the original masterminds used Makoto Ishihara as their disposable, “useful” pawn.

Furthermore, when we analyze the explosive finale on the Maglev, it becomes painfully obvious that Maiko had no idea Osamu planned to blow up the train. This critical detail strongly implies that 15 years ago, there was also a participant who was completely blind to the lethal scale of the mastermind’s true agenda.

The movie isn’t just delivering a nostalgic throwback. The modern kidnapping serves as a brilliant narrative device designed to show the audience audience exactly how the original, hidden conspiracy likely operated.

The “Two-Person” Illusion: Why the FBI Relies on Plea Bargains

On screen, the modern hijacking appears to be exclusively orchestrated by just two people: Osamu and Maiko. As viewers, we easily swallow the illusion that they pulled this off entirely on their own.

But logically, that narrative is severely flawed. To successfully infiltrate high-security zones, kidnap Alan Mackenzie, and rig a state-of-the-art Maglev, they almost certainly required unrevealed accomplices or inside technical support. Pulling off an international terrorist plot with just two people stretches suspension of disbelief to its absolute limit.

This deliberate “two-person illusion” brilliantly highlights why the FBI depends so heavily on plea bargains. Without a suspect cutting a deal and spilling the beans, investigators are entirely at the mercy of whatever narrative the culprits choose to spin. If Osamu and Maiko keep their mouths shut, the true scope of their network remains buried forever.

Conversely, when a plea bargain works, it shatters these illusions and exposes the entire criminal network. If just one minor accomplice had flipped, the true dynamic between Osamu and Maiko would have been instantly exposed.

By forcing us to question if Osamu and Maiko truly acted alone, the film subtly forces us to realize that without plea bargains, the grand architecture of organized crime remains comfortably in the shadows. The movie uses our own skepticism to explain the dark necessity of the very legal system it critiques.

Case Closed: The Scarlet Bullet (2021) Conclusion: The Terrifying Power of Unconfirmed Truths

The Scarlet Bullet doesn’t preach that plea bargaining is inherently evil. Instead, it shines a terrifying spotlight on its greatest flaw: the power to legally mandate a singular, unchallengeable “truth.”

If Makoto Ishihara had been exonerated by DNA, or caught on tape committing the murder, Maiko and Osamu’s psychological torment wouldn’t have festered into global terrorism. What ultimately shattered their sanity wasn’t just the tragedy itself, but the agonizing reality that the truth remained permanently ambiguous.

The film elevates itself beyond a standard whodunit mystery. It masterfully explores the devastating collateral damage that occurs when a bureaucratic system decides a case is “solved” before the actual truth is found.

To summarize our deep dive into the shadows of this film, here are the four core takeaways:

The system rushed to define Makoto Ishihara without fully understanding him. And the children left behind, broken by that legally mandated “truth,” chose to violently resurrect the past to demand answers. This psychological depth is exactly what makes Case Closed: The Scarlet Bullet an unforgettable thriller.

After reviewing the evidence, where do you stand? Was Makoto Ishihara a ruthless killer, or a tragic scapegoat? And when the dust settled, what do you think Maiko and Osamu truly wanted to destroy?
