Detective Conan Episode 1107: I Was Set Up

Spoilers: This article reveals the scam, murderer and revenge motive.

I Was Set Up, international episode 1165 (Japanese episode 1107), is an anime-original case. Sanada really is targeted by a blackmail scheme, but he is also the murderer. He discovers the trap, turns it into an opportunity for revenge, and uses an apparently remorseful confession to steer suspicion toward his supposed friend.

A cancellation that turns into a confession

Real-estate businessman Sanada has called in Kogoro Mouri, yet when Kogoro and Conan arrive, he tries to cancel the job and presses a cancellation fee on them. His urgency makes the dismissal itself suspicious. When questioned, he says that he never intended to kill anyone.

According to his account, Inumaru approached his company three days earlier and threatened him over wrongdoing he did not recognize. Sanada consulted his friend Kawakatsu, who offered to deal with the matter. Inumaru later called to say he was coming over, arrived first, and grabbed Sanada.

Sanada says he shook Inumaru off, only for the man to collapse and stop moving. Kawakatsu then arrived, confirmed the apparent death and helped him bury the body in the mountains. He also advised Sanada to arrange an alibi. The story casts Sanada as someone swept from an unjust threat into a panicked cover-up.

The demand for 30 million yen

The next visitor is Saori Yukawa. She claims that Inumaru cheated her out of 30 million yen and demands repayment. Saying she saw him enter Sanada’s property gives her leverage over a man who supposedly believes he has killed and buried him. Sanada pays to keep her quiet.

The timing makes the events look coordinated. A blackmailer collapses, a helpful friend arrives to manage the body and alibi, then another claimant appears with precisely the knowledge needed to extract money. Conan recognizes the possibility that the death and burial were part of a scheme to make Sanada believe he was guilty.

That explanation is a useful correction to the initial confession, but it is not yet the whole solution. The episode makes the prospect of exposing a fraud feel reassuring just before it produces a body that cannot be dismissed as pretend.

Why finding a real body changes the theory again

Inumaru is genuinely dead when the mountain burial site is examined. A button connected with Kawakatsu appears to implicate the friend who had supposedly been helping Sanada. Kogoro initially moves toward treating Kawakatsu as the killer.

The estimated time of death does not fit the time of the accidental killing Sanada described. His account can no longer serve as a neutral framework for organizing the other evidence. Someone has not merely lied about responsibility; the chronology of the confession itself has been constructed.

Conan also attends to ordinary objects and observations: shopping receipts, sweets given as a present, a picture frame that had been put away but is now displayed, and the housekeeper’s testimony. These details challenge the polished story at points where a frightened witness might otherwise seem persuasive.

The clues work together by testing actions against time and setting. The apparent frankness of admitting an accidental death does not make every part of that admission true. Sanada has offered a damaging-looking version of events because it helps control which questions the investigators ask.

Sanada's revenge and the planted button

Through Sleeping Kogoro, Conan identifies Sanada as the murderer. Sanada had understood the blackmailers’ plan and used it rather than remaining its passive victim. He killed Inumaru, buried him, and left Kawakatsu’s button to redirect suspicion.

The deeper motive reaches back to the robbery in which Sanada lost his wife ten years earlier. Something Inumaru said connected him, in Sanada’s mind, with that loss. Discovering that Kawakatsu was willing to participate in the scheme added a personal betrayal to the older grievance.

His account of the accidental death and the later extortion made his victimhood look like the explanation for everything. In reality, those circumstances were also tools he could use to conceal a deliberate killing and frame another man. The planted button is the clearest physical expression of that reversal.

Sanada confesses and is arrested. The exposed scam remains real, but it cannot absolve him of the separate murder. Holding both facts together is essential to understanding the ending.

A title that changes its owner

The case succeeds through successive changes in perspective: an accidental killer becomes an apparent fraud victim, the fraud produces a real corpse, and the apparent victim emerges as someone directing the final deception. Each change depends on a detail already present rather than simply replacing the story with a new culprit.

Sanada’s loss explains why the confrontation has such force for him, while Kawakatsu’s betrayal makes the situation still uglier. Yet using a trap against its makers does not turn the killing into innocence. Kogoro’s human sympathy and Conan’s attention to evidence pull in different emotional directions without needing to contradict each other.

The most unsettling element is the confession itself. Sanada seems to surrender control by admitting something terrible, when he is actually trying to control the investigation. The final meaning of the title depends on seeing how easily a statement of victimhood can also be a device for framing someone else.
