The episode begins with Detective Sato wearing a ring on her left hand ring finger (the traditional engagement/wedding ring finger). The entire Tokyo Metropolitan Police Department panics, assuming she is engaged to Takagi. However, Takagi is confused because he never proposed. detective conan episode 487

The Main Story: The police department is hosting an annual marathon. During the race, a hit-and-run accident occurs, and the suspect escapes on foot, blending in with the runners. Takagi and Sato investigate, but their personal tension distracts them.

The Twist: Sato reveals that the ring is not an engagement ring, but a "protective charm" given to her by Officer Wataru Date (her late former partner who died in the line of duty). Date gave it to her before a dangerous mission, telling her to return it only when she finds true happiness. Sato has kept it for years.

As Takagi and Sato pursue the hit-and-run suspect, Takagi ends up in a life-threatening situation, similar to Officer Date’s final case. Sato panics, fearing history will repeat itself. However, Takagi successfully captures the criminal and survives.

The Ending: Sato finally takes off the ring, places it on a memorial plaque for Officer Date, and tearfully tells Takagi: “I’m ready to move on.” The episode ends with them walking off together, officially becoming a couple. Takagi jokes about buying a real ring, and Sato smiles.

The murder they investigate is equally poetic. The victim is found in a sealed room, shot with a gun that has no sound—a custom silencer so perfect it leaves no trace.

This is the visual metaphor of the episode: The silenced gun. Lowlights:

Sato’s pain is the silenced gun. She never screams about Matsuda. She never breaks down. She smiles, works, and arrests criminals. But the gun is still loaded. The trauma is still lodged in her chest, waiting for a trigger.

The killer in the episode is a man trying to erase his past—destroying fingerprints, altering identities, silencing the evidence of who he used to be. He is Sato’s foil. He wants to forget. Sato cannot forget.

This is where Episode 487 digs deep into character psychology. Sato is not just excited; she is terrified. Viewers will recall that Sato’s first love, Detective Jinpei Matsuda, was killed by a bomb set by the serial killer "Kamiya" before they could formalize their relationship. Matsuda died with a ring in his locker that he never got to give her.

Sato begins to see parallels: Takagi is going to a dangerous location (a secluded park) to give her a ring. Her PTSD kicks in. She flashes back to Matsuda’s death, worrying that history is repeating itself. She believes in the "curse" of the police love story—that any officer who finds true happiness will lose it in the line of duty.

Why the left ring finger?

In forensic science (which Aoyama adores), the left hand is often the "passive" hand. The right hand does the work—firing a gun, writing a report, handcuffing a suspect. The left hand holds the evidence. It holds the ring. Verdict: If you like character-driven cases with heart,

For Matsuda, the ring was armor. For Sato, the ring on Takagi’s left hand is a symbol of cognitive dissonance. She wants Takagi to be Matsuda (safe, brilliant, heroic) but she loves Takagi for being Takagi (human, clumsy, alive).

The episode argues that we cannot erase our ghosts. But we also cannot let them pilot our present.

Episode 487 is a stand-alone mystery episode that takes place at a planetarium. It is notable for featuring a guest appearance by Heiji Hattori, making it a collaborative case between the detectives of the East (Conan) and the West (Heiji). The episode blends a "locked room" style murder mystery with astronomical themes, requiring the detectives to solve both a mechanical trick and a dying message left by the victim.

Can you skip this episode? No, if you are a completionist or a fan of Heiji Hattori. Yes, if you are only watching the main plot (Black Organization) arc, as this is a pure "filler" mystery case with no impact on the overarching narrative.

Who should watch this?

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.
