Case

Situation

On a rainy day, Kogoro decides to reward himself after gaining a lot of money from the investigation, with Rum asking where Conan could be. As it turns out, he went to the building where the Detective Boys, Rumi and Kobayashi are cheering Shiratori as he is participating in the tournament, with Kobayashi giving him the knight keychain as a lucky charm.

The Bloody Knight

When Haibara and the Detective Boys are discussing the strongest chess piece, Rumi asks her why she knows too much around, in which Conan replies as Agasa taught her how to play chess and other knowledge as well.
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 fix it.
Kuroda then greets Kobayashi and Rumi, he also mentions that he has met Rumi somewhere, even before the event of the burning tent murder case, in which she denies.

Trivia

The suspects' names are related to chess pieces^[1]:
- Kurumi Shiroi (城井来海) comes from "rook" (ルーク ,rūku^?)/"tower" (城 ,shiro^?) ;
- Kinji Ogawara (大河原欽治) comes from "king" (王 / キング ,ō / kingu^?) ;
- Naoto Kishitani (岸谷直人) comes from "knight" (騎士 / ナイト ,kishi / naito^?) ;
- Kunikazu Kisaki (木崎邦和) comes from "queen" (妃 / クイーン ,kisaki / kuīn^?) ;
- Ryoichiro Saso (佐宗涼一郎) comes from "bishop" (僧侶 ,sōryo^?).
On the floor near Kishitani's body is a copy of the Shonen Sunday magazine. It is titled Shonen Yonday (ヨンデー, Yondē) instead of Sunday (サンデー, Sandē).
The chess tournament takes place at West Topia (西トピア Nishi Topia), based on the real Hokutopia (北とぴあ, the "Hoku" means north and "Nishi" means west) building in the Kita Ward of Tokyo. The National Chess Tournaments take place each year at Hokutopia^[2].
Rum wears a cowhide dress shirt.
Juke Hotel is modeled after the New Yorker Hotel and the Waldorf Astoria in downtown Manhattan.
The chess opening played is the Queen's Gambit Accepted.
Amanda Hughes wears her watch with the clock facing the inner side of the wrist, which was commonly done by older people and women, as watches were easy to break and keeping them inside would reduce friction with hard surfaces^[3]. This was notably shown in files 328-330.
Kuroda's car is a white Ford Taurus 4th Generation.
The car tailing Kuroda is a BMW 3 Series (E46).
Rum's car is a Rolls-Royce Phantom V.
The police car is a Ford Crown Victoria 2nd Generation.
The truck that crashed into Kuroda's car is a GMC W-Series.
The ambulance is a Ford E-250.
The firetruck is a Seagrave Aerialscope.
On Conan's phone, his contacts are named as such: Ran-neechan^[4] (Ran Mouri), Hakase^[5] (Hiroshi Agasa), Haibara (Ai Haibara), Mitsuhiko (Mitsuhiko Tsuburaya) and Ayumi (Ayumi Yoshida).

Each Person's "17 Years Ago" videos

In promotion of this case, three original short videos titled “Each Person’s ‘17 Years Ago’”, have been released on the official Detective Conan YouTube channel, each supervised by Gosho Aoyama.^[6]^[7]

Each video features one of the characters—Hyoue Kuroda, Rumi Wakasa, and Kanenori Wakita—reflecting on their memories and thoughts from 17 years ago.

Release Schedule

June 4 – Hyoue Kuroda edition (Video)
June 5 – Rumi Wakasa edition (Video)
