Case 1: Chess Tournament Murder

Situation

The Bloody Knight

On a rainy day, Kogoro decides to reward himself with sushi from Iroha Sushi after gaining lots of money from the investigation. While Ran goes out for some tea leaves, Wakita wonders where Conan could be. Kogoro reveals that he will be cheering for Shiratori, who is going to compete in a chess tournament at Nishitopia building, with Haibara, the Detective Boys, Kobayashi, and Rumi.

At that building, after Kobayashi gives Shiratori a knight keychain as the lucky charm, the kids begin discussing what piece is the strongest. And once again, Haibara gets teased as her knowledge is just outstanding compared to those of her age, Conan then has to explain that Agasa was the reason why Haibara knows so much about chess and other knowledge. Later, the group meets up with other tournament participants, including Kurumi Shiroi, Kinji Ogarawa, Naoto Kishitami and Kunikazu Kisaki, with each of them having their own chess piece as a lucky charm. Ogawara mentions that a chess player named Ryoichiro Saso used Amazing Grace as his phone tune, only to be betrayed by the tune itself.

In the tournament, Shiratori faces Kuroda but suddenly someone’s phone rings, causing Shiratori to be distracted and he is then declared lost. However, when the two meet up with Kobayashi’s group, Shiratori loses his lucky charm somewhere, so he has to go back to the tournament to find it. Kuroda then greets Kobayashi and Rumi, he also mentions that he had met Rumi somewhere, even before the event of the burning tent murder case, in which she denies.

Shiroi, Ogawara and Kunikazu are walking to the waiting room when they hear a strange sound, which would remind them of the ringtone played in the match. Later, Ogawara’s glass suddenly breaks when he is going to have his drink, which makes him scream in fear. Apparently, an arrow has flown through his glass and hit his bag at an almost perfect angle. Conan and Kuroda then try to find the culprit’s trace following the open door, and when they pass by a “cleaning up” sign that looks different than those they have just seen earlier in the restroom, Conan opens a restroom and sees Kishitani’s corpse with several arrows in his body. There are also some items near the scene:

  • A crossbow that could have been used to perform the murder.
  • A magazine that could leave some clue, because of its weird blood stain.
  • A knight keychain that Conan confirms belongs to Shiratori.
Murder
EP1164-1167 Case1.jpg
Location: Nishitopia building
Victim: Naoto Kishitani
Age: 32 years old
Cause of death: Arrow shot wound to the chest
Suspects: Kurumi Shiroi, Kinji Ogawara, Kunikazu Kisaki, and Ninzaburo Shiratori

Kuroda informs Shiratori about the murder scene and that Shiratori is also a suspect. Shiratori agrees with this while trying to provide an alibi, as:

  • He was in one of the restrooms to just find the missing lucky charm, but he did not see any cleaning up sign.
  • He was in the stairs near that restroom area to find the charm, as he might have dropped it there when he was making a call to his butler to inform him about the result. In addition, he did not see anyone walking by when making the call.

The police arrive and Megure begins listening to their report about the incident, he then deduces that the culprit must have escaped. Conan denies this and thinks that there are still 4 people in the building that could shoot Kishitani: Shiroi, Ogawara, Kunikazu and Shiratori, as following him and Kuroda, no one got in or out of the building. Megure wonders couldn’t Kishitani have killed himself, to which Kuroda explains why it couldn't be. Kunizaku expresses that something is wrong when the police trust a boy like Conan, Kuroda points out that his jacket seems to have a strange tear. Shiroi mentions that they heard a strange sound after returning from the match, and when they return to the place they heard the sound, an arrow is seen stuck in the wall.

The police ask what the suspects had done after leaving the match:

  • Kunikazu was buying drinks in the vending machine after he left the match with the victim when Shiroi and Ogawara showed up. After hearing the strange noise, he just played game until the glass broke
  • Kishitani received a message when he was buying drinks like Kunikazu, the message frightened him so he ran away somewhere.
  • Shiroi was going along with Ogawara until she went to the bathroom to see the match again with earphones, so she didn’t notice much noise outside.
  • Ogawara says that he also used the restroom when he separated from Shiroi. He noticed one of the toilets but didn’t know it was Kishitani. After using the restroom, he went to the waiting room with others.

When Megure takes the charm out, Conan can finally see the bloodstained side of it, this reminds both Wakasa and Kuroda of something long ago while Conan is deducing. Megure also states that there is a bloodstained crossword page, indicating that the victim may have left his last word there. The Detective Boys and Haibara mention that there were 2 glass boxes in the trash bin, one with nothing, one with shattered glasses. Conan then smiles, indicating that he knows the truth behind.

Outside the building, Rum is seen smiling in his car with his cigarette.

The Perceptive Devil

Conan calls Agasa to ask how long it takes for him to bring the item, he answers that he has completed the requested item and it’ll need 10 minutes to get there as well. While at the building, Ogawara asks if the three of them are out of the suspicious range, with Kisaki and Shiroi thinking that the culprit must be Shiratori. The Detective Boys and Haibara justify that he can’t be that kind of person, even though he has curly hair, which makes Shiratori speechless. Conan begins his deduction.

    Case 2: The Case 17 Years Ago

    The Perceptive Devil

    After the case is over, it is revealed that Kuroda was the one to let Agasa in, as he entrusted Conan to have Agasa in after hearing Conan say that he and Agasa would demonstrate an experiment that would help solve the case. Ayumi suggests that she, other friends, the teachers, and Agasa go to a family restaurant, Kobayashi agrees as the tournament is now cancelled. Kuroda asks the group if he could borrow Conan to have him questioned for a while. Everyone else then decides to go for the second floor for the capsule toy machines, but no one, except Rumi, knows that the security camera has been hacked and controlled to aim at Rumi by Rum and his subordinate, who then send the image of the target to Korn and Chianti.

    In a room where Conan and Kuroda can talk privately, Kuroda gives the boy the picture showing the dying message left by an American VIP who was assassinated 17 years ago, which means that the case Kuroda is going to ask Conan coincides with one he has been following with Subaru Okiya. Kuroda begins telling him in detail what happened and why he was there…

    Seventeen years ago, Kuroda was having drinks with a friend of his that was living in the U.S and they were discussing the upcoming chess tournament that Kuroda invited him to. During the drinking, they happened to see Haneda Kohji, and after the drinking, they saw Amanda Hughes with her bodyguard walk pass by. Amanda then was seen having a friendly chess match with Haneda while the bodyguard, revealed to be Rachel Asaka, was staring at Haneda when he revealed that she is a type of the woman he loves. He also revealed the temporary condition she has based on just her action.

    The scene changes just as Rumi is having the same condition Rachel was having, which makes the kids worry about her wellbeing, she says that probably she should have rest, and proceeds to go home. But she accidentally breaks Kobayashi’s parachute, which would force her to suggest to Kobayashi to use Rumi’s one while she has to go home via a taxi. Meanwhile, Korn and Chianti are in another building to ambush the target Rum ordered them to, though the condition to perform the sniping sucks.

    The Far-Sighted Bishop

    Continuing the story 17 years ago…

    Possessing excellent memory, Rum accurately identifies all bodyguards seen with Amanda and orders his people to capture and incapacitate them.

    Assault and kidnapping
    EP1164-1167 Case3.jpg
    Location: Juke Hotel, USA
    Victims: Amanda's bodyguards
    Injury: Shocking
    Culprits: Rum's agents

    Rum also notes that a Japanese man he saw is also a person of interest and orders his agents to also take care of him. However, when attacked, Kuroda is able to take them both down.

    Attempted assault
    EP1164-1167 Case4.jpg
    Location: Juke Hotel, USA
    Victim: Hyoue Kuroda
    Age: 33 years old
    Attack Types: Shocking
    Culprits: Rum's agents

    Kuroda begins worrying about Amanda's well-being, so he tries to have her room's number via a receptionist, but fails.

    Meanwhile, having noticed that Rum and his agents are outside the door, Amanda sends Rachel to Haneda's room to retrieve a knight from her chess set to keep her away from the encounter. When Rum comes into the room, he explains that now that they know Rachel is like a daughter to her, the organisation can use that information and now recruit and force her to help them. Rum presents the APTX 4869 pill to Amanda, showing the alternative, but in an unexpected moment, Amanda voluntarily jumps forward and ingests the pill.

    Suicide
    EP1164-1167 Case5.jpg
    Location: Juke Hotel, USA
    Victim: Amanda Hughes
    Age: 81 years old
    Cause of death: APTX 4869 poisoning

    After Rachel reaches Haneda's room, Haneda reveals that Amanda likely sent her away on a wild goose chase on purpose, as there is no way that someone would miss the fact that a knight was missing from the chess case because of the specially designed crevices for each piece. Haneda tells Rachel to hide when Rum and his agents knock on Haneda's door, asking if they have seen a Japanese woman. Haneda says no and swiftly shuts the door. He then goes on to taser Rachel and hide her in the bookcase in his room. Rum then comes back again and notices that the order of the books has slightly changed from before and, knowing that Rachel is hidden in there, reaches out to remove the books.

    At the same time, when Kuroda accidentally knows the room Amanda is staying following a bellhop, Amanda's body is discovered. Kuroda orders the bellhop to call the police while Kuroda examines the scene. He realises that the special guest Haneda said he was going to play chess with was in fact Amanda, so, sensing something is off, he requests the bellhop for the room of Haneda, but will it be in time?

    Before Rum gets the chance to remove the books, Haneda drops his act and tells Rum he remembers seeing him in the news. Haneda is then repeatedly beaten and eventually fed the APTX 4869 pill as the police are arriving due to. Before he dies, he leaves a final message by cutting up a mirror with the text "Put on mascara".

    Murder
    EP1164-1167 Case6.jpg
    Location: Juke Hotel, USA
    Victim: Kohji Haneda
    Age: 28 years old
    Cause of death: APTX 4869 poisoning
    Culprit: Rum

    Kuroda again arrives not in time, as Haneda is also dead in a really messy scene. At this time, Rachel wakes up and, under the assumption Kuroda killed Haneda, begins attacking him. Having no choice after she breaks some of his ribs, he takes Rachel down In a moment of shock when she sees a photo of Amanda's corpse on a phone.

    The Queen's Gambit

    Rum and his agents outside the hotel see chess notes flying out of the hotel, and Rum deduces that Rachel will be snuck out of the hotel using the bookcase again. However, as they reach Haneda's floor, Kuroda, wheeling a suitcase with Rachel in it, manages to sneak by. After Rum realises that Rachel was in the suitcase, he and his agents get in his car and begin chasing Kuroda's vehicle. However, Kuroda's car ends up being ran into by a truck and his car catches on fire. Seeing the commotion, Rum decides to step away.

    Accident

    Age: 33 years old
    Injury: Blunt force

    In his last moments of consciousness, Kuroda asks an EMT about how the female in his car was, and the EMT says that only he was found, suggesting Rachel escaped before the ambulance got there.

    Back in the modern day, Conan is ready to tell his deciphering process about Amanda’s final word; while Agasa, Kobayashi, and the children are impatient that 40 minutes have passed and Conan hasn’t returned, with Kobayashi hoping that Rumi does not soak herself wet. It is partially true as she is standing on the rooftop of another building other than one of the kids and the snipers for something. Rum is regretting not killing them earlier and has to wait til now when Chianti suddenly laughs as some assumed idiot tried to commit a robbery with just a knife.

    Method: A knife
    Culprit: Unknown
