The guests decide to explore the spacious wine cellar belonging to the restaurant. While they look for a wine, Sawaki narrowly avoids getting shot by an arrow, a trap with Eight of Spades apparently set by Jo Murakami. The scene transitions again to the Detective Boys waiting for Professor Agasa on a bench . While waiting, Ayumi plays with a love oracle, and the machine tells her her and Conan are a perfect match. She then asks the oracle to tell Conan's romantic fortune, which is "A chance for an A (kiss)". Conan wonders just how old that machine is - "A", "B" and so on were very ancient expressions for romantic events. Agasa finally turns up and takes the Detective Boys to the Tohto Aeronautic Memorial Museum. Towako Okano (She was suspected as the target's name contains the kanji for 10) - Tammy Diez (She was suspected as the target's last name is the number 10 in Spanish)

Shinichi practiced shooting a gun at a shooting range at their Summer Retreat in Hawaii, when he was with his father.When Conan calls Ran as Shinichi later, she asks him if he would do the same if Ran was held hostage, even if it meant injuring Ran. Conan says that although Kogoro did shoot Eri, he wonders if that was the whole truth, and hangs up.

Midori Kuriyama calls for an ambulance and gets Eri to the hospital in time so she survives the poisoning. There is a paper flower on the chocolate box that seems familiar to Conan. During dinner, Ran shows a suprising amount of knowledge about wine, explaining to Conan why the sommelier Kohei Sawaki wears a grape badge and what a tastevin is for. Eri and Kogoro realise their daughter has grown up a lot. Shinichi Kudo (His name contains the kanji for 1) - Jimmy Kudo (Only child and number 1 at many things) Everyone decides to get something to drink while they wait for Asahi to join them. Conan gets a box of juice for Ran and is surprised to see Kogoro help himself to a juice as well.The search for the next target, a "number nine", continues. Kogoro says he can't think of anyone but he does know someone with an eight, Kohei Sawaki. Therefore, Megure, Shiratori, Ran, Conan and Kogoro visit Sawaki at home to warn him. He shows them around and presents his large wine collection to them. Conan has a look through Sawaki's apartment and notices a dent in the floor. Sawaki explains he dropped a wine bottle. When asked about his plans for the next couple of days, Sawaki explains that he is supposed to meet Kazuyoshi Asahi in his not-yet-opened complex AquaCrystal to discuss the restaurant Asahi plans to open in the building. Shiratori corners Sawaki and points his gun at him. Conan notices his hands are shaking and worries that Shiratori might accidentally hit Ran if he shoots with unsteady hands. Shiratori drops his gun and confers with Megure, preparing to take Sawaki down. Sawaki notices and demands Conan bring the gun to him. As Conan walks up to Sawaki, he finally realises why Kogoro ended up injuring Eri ten years ago. An injured hostage is a burden for the kidnapper and he wanted to make Murakami let go of her. Conan decides to do the same, firing the gun and lightly grazing Ran's shoulder. Sawaki lets go of her and Ran faints from hypothermia and exhaustion. Kogoro takes Sawaki down and helps Conan stop Ran from sliding down the rooftop. Sawaki wants to kill himself but Kogoro stops him, saying he has to face the consequences of his crimes. Kogoro decides to tell everyone about the ongoing investigation, saying he fears Jo Murakami, who has recently been released from prison, might target all of them. Osanai and Nishina get into an argument. Osanai complains that a restaurant that Nishina recommended in his book was actually terrible and that he has no taste at all.
