Spoilers: This article explains both attacks and identifies the person who kills Tamai.
The Four-Person Class Reunion, international episode 1177 (Japanese episode 1119), is an anime-original case with three involved suspects. Okawa and Sasaki attack Tamai and throw him into a river, but he survives. His fiancée Emi Maeda later strikes him at the pool, causing the death that Conan and Kogoro investigate.
An engagement disturbs an old hierarchy
Four former schoolmates meet at the luxurious home of Tamai, owner of the high-end host club Sunset. He announces his engagement to Maeda, the former student-council president. Okawa, formerly the secretary, and Sasaki, formerly the treasurer, appear less comfortable with the news than the celebration suggests.
About a month later, Tamai visits the Mouri Detective Agency because strange things have been happening around him. He wants an investigation and protection, and arranges to meet Conan and Kogoro at the club the next day.
They arrive to find him dead in the garden pool. The blow to the back of his head has left a curved mark resembling the Japanese syllable no, and there are bite marks on both wrists. Those injuries point toward contact with other people, but initially seem difficult to fit into one event.
Why three alibis do not settle the three roles
The estimated time of death is around half past noon on the previous day, after Tamai had visited Kogoro. Maeda was involved in a live shopping broadcast, Okawa was performing surgery and Sasaki was in court. Each appears to have a substantial alibi associated with the relevant period.
Their accounts also introduce a school-era story in which Tamai supposedly took the blame for stolen student-council funds and saved the others’ futures. The two men have continued treating him as a hero.
The essential problem is whether the time of death is also the time of every injury. If the wrists and head were injured in separate confrontations, an alibi for one moment cannot automatically answer what a suspect did earlier.
The pool contains a trace of the river
Conan notices aquatic weeds caught in the pool’s drain. Their presence is odd in that setting and suggests that Tamai reached it after being in another body of water.
The investigation extends to Haido Bridge over the Haido River. Scrapes on the railing and Tamai’s belt, together with footprints on the riverbank, support a sequence in which he fell into the river and then climbed out.
These traces explain why discovering him in the pool does not locate his only encounter with violence. He swam out of the river and returned to Sunset alive. The weeds link the two sites, while the injuries have to be divided between what happened before and after that return.
The supposed hero had been receiving money for twenty-three years
Records of payments extending over twenty-three years overturn the flattering version of the student-council incident. Tamai had leverage over Okawa and Sasaki and continued receiving money from them. The relationship was sustained by pressure, not simply gratitude.
Drone harassment leads into their attack on him at the bridge. During the struggle, the men leave the bites on his wrists before throwing him into the river. Dental comparison connects the marks with the two men, while the payment records explain the grievance behind the assault.
The engagement intensifies their resentment toward someone still occupying the position of celebrated benefactor. Their attack is exposed, but it cannot explain the final death on its own because Tamai survived the fall.
That survival is the second turn in the mystery. Identifying two assailants does not finish the case; it makes the remaining injury and the later encounter more important.
Maeda's lunch and the reversed letter
Maeda says she went out for lunch after the broadcast. Something she told the staff reveals that she had brought a homemade lunch instead, undermining the account used to cover her movements.
She was waiting by the pool with food for Tamai. For her, marriage offered the possibility of leaving the shopping-show persona behind and returning to ordinary life and cooking. He instead intended to keep her earning as a television-shopping attraction, with himself managing her.
After his return from the river, the confrontation over that future provokes her to strike him with her bag. The curved wound is the reversed impression of an e on the bag’s buckle, rather than a message deliberately written in Japanese.
The lunch detail exposes the opportunity; the buckle accounts for the distinctive fatal injury. These are separate from the bite marks that identify the earlier attackers. Conan’s solution succeeds by assigning each trace to the right encounter instead of demanding one explanation for everything.
Why the reunion remains uncomfortable after the solution
All three classmates’ involvement comes to light, and Maeda is taken away. The staging of the departure recalls the old student-council arrangement, with its president seemingly escorted by the two men who once served under her.
That echo is what gives the ending its particular bitterness. The school relationship has persisted into adulthood, but its language of loyalty and admiration conceals payments, resentment and control. Even the engagement is viewed by the people involved through incompatible ideas of what their future should be.
The evidence remains satisfyingly concrete despite those tangled relationships: teeth identify contact, payments reveal pressure, weeds connect locations, lunch undermines an account, and the reversed letter explains the wound. The closing food joke provides release, while the old hierarchy remains the image that lingers.
