The Setup Conan, Ran, Kogoro, and Heiji Hattori (who has traveled from Osaka) visit a large planetarium. Kogoro has been hired by the planetarium's director to investigate a series of threats and sabotage incidents occurring at the facility.
The Incident During a special projection show where the audience sits in reclining seats in the dark, a gunshot rings out. When the lights come back on, the planetarium's curator is found dead in the center of the room. The room was locked, and the audience was under observation, making the insertion of an outside killer seemingly impossible.
The Investigation Conan and Heiji discover that the victim managed to leave a dying message using the planetarium's star projector. Before dying, he manipulated the projector to display a specific constellation or star pattern. The duo must decipher the astronomical code while deducing how the killer managed to shoot the victim in a crowded, locked room without being seen. detective conan episode 487
The Resolution The detectives deduce that the killer used the darkness and the specific mechanics of the reclining seats to hide the murder weapon and the act of shooting. The dying message points to the killer's identity through a play on star names or mythological connections associated with the constellations.
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. Conan realizes the killer used the "spilled ink"
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.
This episode is part of the long-running "Metropolitan Police Love Story" series, focusing on the romantic relationship between Detective Miwako Sato and Detective Wataru Takagi.
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. The Incident During a special projection show where
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.
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.
The episode opens with a seemingly routine investigation. A man named Susumu Hatamoto has been murdered inside a sealed room. The room is bizarrely decorated with Okame masks and Hannya masks (traditional Japanese Noh masks representing women and demons, respectively). When the police arrive, they discover that the victim’s left hand is missing—specifically, the ring finger.
Conan, Ran, and Kogoro happen to be nearby, leading to the usual collaboration. However, the focus quickly shifts away from the locked-room mystery and onto Takagi and Sato.
