Welcome back, truth-seekers! Today, we’re unpacking a fan-favorite milestone in the long-running Metropolitan Police Detective Love Story arc. Episode 487, titled "
Metropolitan Police Detective Love Story 8: The Left Hand's Ring Finger
," originally aired as a one-hour special and is a must-watch for anyone shipping Takagi and Sato. The Mystery: Poison and a Locked Room
The episode kicks off when Conan, Kogoro, and Ran encounter Detective Sato at a crime scene. A man named Moroguchi has been found dead from poisoned coffee in what appears to be a classic "locked room" setup.
As usual, Conan is the one to spot the tiny details the adults miss. He drops strategic hints that help Sato and Takagi realize the killer used a clever trick involving a cassette tape string to slide a key from a window directly into the victim's hand, making it look like the room was sealed from the inside. It’s a classic Detective Conan mechanical puzzle that really tests your spatial reasoning! The Romance: Is Sato Engaged?
While the murder mystery is solid, the real draw here is the "Love Story" subplot. The precinct is in an absolute uproar because Sato is seen wearing a ring on her left ring finger.
Poor Detective Takagi is practically in a tailspin, and the rest of the police force (led by the ever-mischievous Yumi) is buzzing with rumors.
The Reveal: In true Sato fashion, the ring isn't a secret engagement—it’s actually a charm she wore to ward off unwanted attention, completely unaware of the romantic symbolism behind which finger she chose to put it on.
The Vibe: The episode perfectly captures the "will-they-won't-they" fluff that makes this secondary couple so endearing.Production Highlights
New Theme Song: This episode marked the debut of a new ending theme, "Sekai wa mawaru to yuu keredo" by GARNET CROW.
Manga Roots: The case is adapted from Manga Chapters 576–578 (Volume 56).
Format: Being a one-hour special, it has a much better pacing than the standard 20-minute episodes, allowing both the case and the character development to breathe.Final Verdict
Rating: 8.5/10If you’re a fan of the police cast, this is essential viewing. It balances a clever murder trick with the hilarious interpersonal drama of the Tokyo MPD. Plus, seeing Conan and Ran react to the "fluff" from the sidelines is a treat for any longtime viewer.

The Echo of a Silenced Gun: Why Detective Conan Episode 487 is a Masterclass in Melancholy
For the uninitiated, Detective Conan (Case Closed) is often pigeonholed as a simple "murder of the week" whodunit. A shrunken genius solves a puzzle, points a finger, and the culprit collapses in tearful confession. Rinse and repeat.
But for those who have walked the 1,000+ episode journey, we know the series has a hidden, darker spine. Every so often, Gosho Aoyama stops playing fair. He stops giving us a puzzle and gives us a wound.
Episode 487: "Metropolitan Police Detective Love Story 8: The Fingerprint of the Left Ring Finger" (often shortened to "Left Hand’s Ring Finger") is not just another installment of the Takagi-Sato saga. It is a chilling, melancholic masterpiece that explores the ghosts we carry inside our skin.
Here is why this episode stands as one of the most emotionally devastating and expertly crafted chapters in modern anime mystery.
3. Key Characters

Heiji Hattori: His presence elevates the episode. His dynamic with Conan is one of the highlights, showcasing their friendly rivalry and shared deductive prowess.
Kogoro Mouri: Serves as the initial point of contact for the case. He is largely baffled by the trick but provides the authority for the group to be there.
Ran Mouri: Acts mostly as the emotional support and witness, typical of these "detective boys" style cases, though she notices clues she doesn't realize are significant.
Detective Conan Episode 487: The Curse of the Masks – A Deep Dive into the Metropolitan Police Love Story
When discussing the most impactful episodes of Detective Conan (also known as Case Closed), fans often point to the sprawling Black Organization arcs or the thrilling showdowns with Kaito Kid. However, nestled in the late 400s is an episode that stands as a masterclass in tension, character development, and emotional resonance: Detective Conan Episode 487, titled "The Metropolitan Police Love Story 8 – The Left Hand Ring Finger" .
For viewers searching for this specific entry, you are likely looking for more than just a plot summary. You want to understand why this episode is considered a turning point for Detective Takagi and Officer Sato, how the "curse" of the masks works, and where this fits into the broader Conan timeline. Let’s break down every detail.
Why This Episode Matters for Long-Time Fans
In the grand tapestry of Detective Conan, Episode 487 is a watershed moment. It is the episode where Sato finally stops running.
She confesses—not explicitly, but tacitly—that she has been using danger as a form of suicide by proxy. Every time she chased a bomb threat or a killer, a part of her hoped to join Matsuda.
Takagi’s survival in this episode is not luck. It is choice. He chooses to stay alive for her. And by the end, when Sato looks at the ring on his finger—now his own, not a prop—she sees the future, not the past.
The Turning Point: The Marriage Proposal
While chasing down clues, Takagi suddenly asks Sato to meet him at a specific location that night. He claims he has something important to tell her—something he can only say face-to-face.
Fans of the series know that Takagi is notoriously shy. His hesitation to commit has been a running gag for hundreds of episodes. But here, the atmosphere is different. He holds a small box in his pocket. It is heavily implied (and later confirmed) that Takagi intends to propose marriage.
Three years prior to this episode’s timeline, Matsuda was Sato’s partner and first love. Brash, genius, and wearing a ring on his left ring finger (to avoid marring his dominant hand in a fight), he was blown up by a serial bomber. He died alone in an elevator, leaving Sato with nothing but a text message and a trauma that bleeds into every case she works.
Episode 487 doesn't explain this again. It assumes you remember. That is the genius of the "Love Story" arc—it is a serialized tragedy.
When Sato looks at Takagi’s left hand, she doesn’t see her partner. She sees Matsuda. The identical finger placement isn't a clue for the thief; it is a psychological Rorschach test. She is projecting the dead onto the living.
The Resolution
Conan tranquilizes Kogoro. Using the Sleeping Kogoro persona, he reveals that the killer is the student, Takuya Hane.
Motive: Shima had discovered that Takuya’s breakout hit from five years ago was actually a stolen composition from a deceased rival. Shima was planning to expose him during the event.
Evidence: The ink. Takuya claimed he rushed in after hearing a scream, yet his alibi for the time of the murder relied on the power outage. However, the ink spill pattern proves it was poured deliberately after the water was added to slow the drying time, meant to frame the rival composer who was known to be messy. But crucially, a trace of the "missing" sheet music was found stuck to Takuya's shoe—it wasn't stolen music, but a document proving Shima intended to disinherit Takuya.
Closing Scene:
As the police lead Takuya away, Ran comments on how tragic it is that talent was wasted on jealousy. Conan spots the Kid in the crowd (a cameo), who winks and disappears, implying the "Phantom Thief" was also interested in the rumored diamond but found the "treasure" to be nonexistent. Conan smiles, realizing Kid left a calling card on Kogoro’s back.
Detective Conan Episode 487, titled "Metropolitan Police Detective Love Story 8: The Left Hand's Ring Finger", is a standout installment in the long-running Case Closed series. Originally aired on October 15, 2007, this episode masterfully blends the series' signature intricate mystery with the fan-favorite romantic tension between Detectives Miwako Sato and Wataru Takagi. Episode Overview
Title: Metropolitan Police Detective Love Story 8: The Left Hand's Ring Finger Original Air Date: October 15, 2007 Manga Source: File 576–578 (Volume 56) Case Type: Locked-room murder The Romantic Rumor Mill
The episode begins with a buzz at the Metropolitan Police Department. Detective Sato is seen wearing a ring on the ring finger of her left hand—traditionally the finger for engagement rings. This sends shockwaves through the department, particularly among the male officers who are notoriously protective of Sato. Detective Takagi, who did not give her the ring, is left in a state of depressed confusion, wondering if someone else has captured her heart.
It is later revealed that the ring was actually a gift from Yumi Miyamoto, who told Sato it was a "charm" to keep "bugs" (unwanted suitors) away. Sato, being somewhat dense in romantic matters, took the advice literally without realizing the significance of which finger she chose. The Case: The Locked-Room Mystery
While the police department is distracted by office gossip, Kogoro Mouri is invited to an interview with a famous but arrogant mystery writer, Masataka Moroguchi. Moroguchi is obsessed with analog technology and recently acquired a gaudy, diamond-encrusted ring.
The next morning, Moroguchi is found dead from cyanide poisoning in a sealed room. The key to the room is found clutched in his own palm, and the only other opening is a window too small for an adult to pass through. Suspects & Motives Kakuji Dejima: Moroguchi’s interviewer. Wataru Tarumi: An editor. Harue Anabuki: Moroguchi’s housekeeper. The Resolution
Conan Edogawa, naturally, identifies the trick behind the "locked" room. The culprit used a cassette tape string looped around Moroguchi’s ring to create a "zip-line" from the small window to the victim's hand. This allowed the killer to slide the key directly into the deceased man's palm from outside the room.
The murderer is revealed to be Kakuji Dejima, who sought revenge for his friend and former assistant of Moroguchi, Akiba. Moroguchi had used Akiba as a "test subject" for his macabre murder ideas, which eventually led to Akiba's death—a tragedy the police had originally ruled a suicide. Ending and Legacy
The episode concludes with a classic "Takagi and Sato" moment. After Sato realizes the misunderstanding her ring caused, she accepts Takagi's offer to replace the "charm" with a ring of his own choosing—though the romantic progress remains characteristically slow.
For fans, Episode 487 is a perfect example of why the Metropolitan Police Detective Love Story sub-series is so beloved, offering high-stakes deductive reasoning alongside the endearing, comedic development of the series' secondary cast.
The "Curse" of the Masks
The suspect list includes three women, all of whom are traditional mask makers. As the investigation unfolds, Sato learns a terrifying local legend: The Curse of the Cursed Masks. According to the lore, anyone who steals a demon mask (Hannya) will be killed, and the ring finger of their left hand will be severed. The victim was found with a Hannya mask nearby, suggesting the curse is at work.
