## Plot[[edit](/wiki/index.php?title=Crossover_(manga_chapter)&action=edit&section=6 "Edit section: Plot")]
The [Detective Boys](/wiki/Detective_Boys "Detective Boys") are eating at the family restaurant Danny's with Professor Agasa after going to the movies, where they watched "[Kamen Yaiba](/wiki/Kamen_Yaiba "Kamen Yaiba") vs. Cosmo Detective Ginga: The Movie", a crossover between the two series. Ayumi particularly liked the scene in which the female Yaiba Fūko (風子) tended to the wounds of rival Ginga. Such a surprising scene can only be seen in a crossover, says Mitsuhiko, but Haibara sees it more as a typical fling mentality, in which you quickly find a new person more attractive than your old partner because you long for a change. She however says she at least liked the film's theme song, which is by the band The Knight Hearts, a group of four men who wear knight-like costumes and are currently topping the charts.
They have an upcoming concert, but just as Haibara is about to look up the details, they are interrupted by a woman called Tokumi Nagasu, who says that The Knight Hearts will be playing a concert at the [Tohto Dome](http://en.wikipedia.org/wiki/Tokyo_Dome "wikipedia:Tokyo Dome") next Saturday at 6PM. Tickets sold out within ten minutes, but she and her friends were fans of the band since their indie days, which is why they received the tickets for free. Tokumi brags about it and also shows a photo of herself and her friends together with The Knight Hearts, who apparently had a fifth member at the time. Laughing, Tokumi walks away from the table while her friend Mao Toya apologizes to the Detective Boys, saying that Tokumi has been spinning her wheels since the band's breakthrough. Tokumi's friend Sumika Kokonoe urges her to apologize to the children later, but Tokumi sees no point in this as she will never see the children again anyway. The three friends are led to their table by the fourth member of the friend group, Yasuko Aijima, who works as a waitress in the restaurant. The four friends take a selfie together before Yasuko goes back into the kitchen.
Meanwhile, the detective boys have ordered their food. Before it arrives, Genta and Ayumi quickly go to the toilet, while Mitsuhiko goes to the counter to buy some soup to takeout for his mother. Ayumi sees her teacher Sumiko Kobayashi in the ladies' room, Genta sees detective Chiba in the men's restroom and Mitsuhiko sees Shukichi Haneda at the counter. Agitated, the three children, Agasa, Conan and Haibara talk about their encounter. They deduce that Shukichi, Kobayashi and Chiba are here in the restaurant on dates with their respective partners. They want to look for the couples in the restaurant and tease them a little. Conan, Haibara and Agasa advise against it when the lights suddenly go out. A waitress comes in with a birthday cake and they sing happy birthday to a child. The lights come back on and Mitsuhiko, Genta and Ayumi have disappeared again.
Meanwhile, Yasuko serves her friends a plate of [maritozzo](http://en.wikipedia.org/wiki/it:maritozzo "wikipedia:it:maritozzo"), an Italian dessert. The boss of the restaurant wants to put the dessert on the menu soon, and Yasuko wants her friends to try it first. Tokumi is ready to dig in, but Sumika first takes a photo for her social media profile and adjusts the plate so that the angle is just right. Before Tokumi can take a bite, Mao intervenes, fearing that Tokumi will eat it all, and she uses tongs to divide the maritozzo onto small plates, after which she gives Tokumi a plate with three pieces.
Meanwhile, Genta, Ayumi and Mitsuhiko are back with Conan, Haibara and Agasa, making disappointed-looking faces. They have found the couples, but instead of being together, they are with the others' partners. They show what they mean by this with photos as proof: Kobayashi is eating with Chiba, Shukichi with Naeko and Shiratori with Yumi. Conan is confused by all this relationship confusion, but Haibara thinks she knows the answer: the couples are all cheating. She wants to get to the bottom of the matter, as she is, after all, the "affair researcher", but Conan holds her back.
At the friends' table, the Maritozzo tasting is in full swing and Sumika and Mao find the desserts very tasty. Tokumi thinks the same, but something about the cream filling bothers her. She licks her thumb and suddenly starts to gasp before letting out a scream and tipping over backwards in her chair. The three other friends scream in horror, which is noticed by both the detective boys and the "cheating" police detectives. Conan and Chiba rush to the body, but Chiba can no longer feel a pulse. Shiratori arrives and detects the smell of cyanide coming from Tokumi's mouth. Yumi and Naeko also arrive, and Yumi tells Naeko to call an ambulance and Sato. A moment later, the shock of realization sets in as all the couples notice each other. The partners eye each other grimly and suspiciously, while Conan looks at them all with an annoyed expression.
