Major spoilers follow for the Haneda case, the identities of Asaka and Rum, and the present-day confrontation in The 17-Year-Old Truth.
Rum is responsible for the deaths of Amanda Hughes and Koji Haneda, while Rumi Wakasa is Amanda’s surviving bodyguard, Asaka. Hyoue Kuroda becomes involved through a secret police assignment and is injured while helping Asaka escape. Amanda’s final message warns about someone’s eyes, and the danger continues into the present when Rum sends snipers after Wakasa.
This guide covers The Perceptive Devil, The Far-Sighted Bishop and The Queen’s Gambit: international episodes 1223–1225 (Japanese episodes 1165, 1166 and 1167). They continue the manga-based Volume 104 story begun in The Bloody Knight. The central flashback is discussed through Files 1106–1109, within the broader series drawn from Files 1103–1109.
Kuroda’s photographs open the hotel’s past
The present-day chess murder gives Kuroda a reason to approach Conan. He has just watched Conan interpret a knight left as a dying message, and he wants help with photographs of another arrangement: a knight marked red around its eyes and a wristwatch bearing a lipstick mark. Amanda left those objects seventeen years earlier.
Earlier references in The Marriage Registration’s Password and Just Like a 17 Years Old Crime Scene established Haneda’s death as a continuing mystery. Here the story moves beyond the outline of an unsolved case and shows the people inside the hotel on the day it happened. The old Rum candidates acquire distinct histories rather than remaining interchangeable suspicious figures.
Asaka is Amanda’s bodyguard and the person she raised
Wakasa’s identity is made explicit: she was Rachel Asaka, Amanda’s bodyguard, aged twenty at the time of the case. Their bond extends well beyond employment. Asaka’s father had also protected Amanda and died shielding her during an attack.
Asaka saw the attacker, testified and entered witness protection. Yet she chose to return to Amanda and follow her father’s work as a bodyguard. With her mother already dead from illness, Amanda had become a parental figure, and Amanda in turn regarded Asaka much like a daughter.
That relationship changes the meaning of the hotel crisis. Protecting Amanda is a personal commitment for Asaka, while Amanda’s concern for the young woman is more than concern for a member of her security staff. Losing Amanda means losing someone central to the family Asaka still had.
In her conversation with Haneda, Asaka describes temporary loss of vision in her right eye, identified in the story as amaurosis fugax. The episode associates these spells with severe emotion or stress. This explains the condition discussed in the flashback; it does not establish that Wakasa’s present-day vision is always normal or settle every later change to that eye.
Haneda chooses to shelter Asaka
Haneda is shown alive, close enough to Amanda to meet with her privately and openly interested in Asaka. Amanda sends Asaka to retrieve something from his room, leaving her own side exposed as Rum approaches. The errand connects the two rooms while separating Asaka from the person she protects.
When Rum’s group comes looking for Asaka, Haneda hides her. He gives her his cherished shogi piece as a protective token, then incapacitates her with a stun gun so he can conceal her from the pursuers. His action keeps her out of sight while leaving him to face the men searching his room.
His words about a bishop watching from far away become a promise of future resistance. Paraphrased, the idea is that staying out of an enemy’s reach while continuing to watch can eventually create a chance to counterattack. The shogi piece carries that thought forward after his death.
Haneda recognizes a connection between Rum and Renya Karasuma and brings up Karasuma during the confrontation. Rum kills him with APTX 4869. This accounts for Haneda’s name appearing on the drug’s victim list, a detail that had linked his case to Conan’s much later experience.
Haneda also cuts the hand mirror marked PUT ON MASCARA to leave a message pointing toward Karasuma. That message concerns the organization behind the attack. It must be distinguished from Amanda’s separate knight-and-watch warning, even though both are left during the same hotel crisis.
The flashback gives Haneda choices as well as a fate. He is a gifted player, but the decisive part of his role is his effort to protect Asaka while confronting someone connected to the Black Organization’s leadership. His death follows that effort to keep another person alive.
Kuroda came on a secret assignment
Kuroda’s apparent reason for being at the hotel is to watch the chess tournament with a friend. His actual purpose includes a confidential assignment from his superior to meet Amanda. His affiliation is identified as the Security Planning Division within the National Police Agency’s Security Bureau, associated with Zero.
An assault in a restroom alerts him to trouble in the hotel. He subsequently discovers Amanda and Haneda dead, becoming involved in a crisis he did not plan. The official role explains why he had intended to meet Amanda, while the unfolding attack explains why his connection to the case becomes so personal.
Kuroda finds Asaka, whom Haneda has hidden, and tries to get her out of the hotel. Rum is still searching for her; learning that the police have not yet found Haneda’s body gives him a reason to return to that room. The attempt to save Asaka takes place under the continuing threat of discovery.
While driving to help her escape, Kuroda is cornered by Rum’s group and suffers a serious injury. He damages his right eye and remains unconscious for years afterward. The flashback supplies the connection that the younger, uninjured Kuroda in The Bloody Knight had only raised as a question.
Rum’s memory makes familiar bodyguards vulnerable
Rum, now living under the name Kanenori Wakita, acts directly in the old case as the Black Organization’s second-in-command. At that time he still has both eyes. The story attributes an extraordinary photographic memory to his left eye: faces once seen can be retained and recognized.
Amanda’s reliance on trusted bodyguards becomes a vulnerability because Rum remembers the people who have protected her before. He identifies and has the guards other than Asaka captured. Familiarity that should provide security instead allows him to separate Amanda from her protection.
The account also connects that memory with Rum’s ability to notice relationships, compromising conduct and weaknesses among powerful people. It has helped the Organization extend its influence. In his younger years, the ability is described as belonging to both eyes; by the hotel case, it remains in the left. These are properties the story assigns to Rum, rather than a general claim about human vision.
Rum explains that his code name was inherited from his father, who had long served the person above them. The revelation makes Rum more than an isolated operative: his role is connected to an earlier generation serving the Organization’s leader.
Amanda’s message says to watch out for the eyes
Amanda leaves the arrangement while dying after taking APTX 4869 during her confrontation with Rum. Kuroda finds the knight and watch but cannot decode them at the time. Seventeen years later, he asks Conan to interpret the photograph after hearing his explanation of the tournament case.
The first part is the lipstick impression on the watch face. Amanda deliberately gives it the shape of a mouth and removes its two ends. Read as the word MOUTH, removing the first and last letters leaves OUT. The object itself supplies WATCH, producing the warning WATCH OUT.
The red marks around both eyes of the knight then indicate the subject of the warning: someone’s eyes. The watch, altered mouth shape and marked eyes have to be read together. None of the objects alone communicates the complete caution.
Conan and Kuroda reach that warning and recall the man Kuroda passed in the hotel, whose monocle and snake-like gaze left an impression. Their deduction does not at this point establish the full memory ability that the flashback reveals to the audience. Recognizing a warning about an eye and understanding exactly why that eye is dangerous are different steps.
Amanda’s warning may refer specifically to Rum’s memory: he has just used it to identify the people guarding her. That is the interpretation supported by the surrounding events, while Conan’s later attention to the selective targeting of the bodyguards points toward the same unresolved question.
Wakasa’s counterattack brings the past into the present
Rum suspects that Wakasa is the Asaka who escaped him. He wants to remove someone who may have heard his voice and could provide a route back to him. He orders Chianti and Korn to wait for her as she leaves the building, turning the historical revelation into an active threat.
Wakasa anticipates the attack. She has Kobayashi carry her umbrella, using the resulting confusion to gain an opportunity to shoot Chianti. Rum compares the move to a gambit, in which a piece is offered to gain a strategic advantage.
The maneuver is troubling because it brings Kobayashi and the Detective Boys into danger. That risk does not establish that Wakasa intends their deaths, and the scene should not be read as confirmation that they have been killed. It does show how ruthless her fight with Rum can become around people who do not share her knowledge of the threat.
Wakasa holds the shogi piece Haneda entrusted to her as she acts. His advice about a distant bishop now has a visible response: years of watching can produce an opening to strike back. The keepsake links her current resistance with the person who concealed her when she could not protect herself.
Tsutomu’s disappearance and Rum’s missing eye remain open
At the end of the day, Conan exchanges information with Shuichi Akai. Tsutomu Akai was not involved at the hotel on the day of the murders. His involvement began when the head of the Haneda family asked him to investigate; he went to America afterward and did not return.
This establishes the order of his involvement without filling in the missing later events. The connection between Tsutomu and Asaka remains unclear at this stage. Nor does the hotel case explain when Rum subsequently lost the left eye that was still intact during those events.
A later clash with Tsutomu is one possible explanation for Rum’s eye injury, but it remains a theory here. Rum’s closing remark about turning back the time of his right eye likewise raises a question about recovering an earlier ability; it does not identify a confirmed method or settle the left eye’s fate.
Why the revelation still feels dangerous
The series answers several longstanding questions together: who Asaka is, how Kuroda entered the case, why Haneda became a victim and what Amanda arranged in her final moments. Its emotional center is the protection passed between them—Asaka’s commitment to Amanda, Haneda’s decision to hide Asaka, and Kuroda’s attempt to get her away.
Yet the ending refuses to leave those choices safely in the past. Rum still wants the survivor removed, Wakasa is prepared to counterattack, and people around them can be drawn into the line of fire. The old message has been understood more clearly, but the need to watch out has become immediate again.
