Case

Situation

Heiji and Kazuha visit Tokyo where the two part ways. A murder occurs at the restaurant Kazuha is in, forcing Kogoro, Ran, Masumi, Heiji, and Conan to investigate.

Murder
	Location: Danny's Victim: Kengo Shibamiya Cause of death: Poison Suspects: Rakutoshi Sugai, Toru Amakasu, and Sanpei Toujou

The witness is Andre Camel who explains the victim's last words were a confession to a poisoning. Heiji reveals the victim was speaking in a Kansai dialect and the victims actual words were referring to an unknown culprit as the poisoner. Realizing the culprit is still in the restaurant, the police narrow down the suspects to three people without alibis. After Heiji is unable to trick the culprits into revealing their Kansai dialect, Conan arranges the three culprits to drink salty soup.

Resolution

Tooru Amakasu is revealed to be the culprit after exclaiming the soup to be Tsurai (辛い?, lit. "Spicy"), a Kansai dialect for Tokyo's Shoppai (塩っぱい?, lit. "Salty") using the (somewhat incorrect) Kansai expression "spicy" (karai) instead. Another fator is the suffix "-sa" used in the Kansai dialect to finish sentences, a habit which Amakasu has maintained during the investigation. And when Conan subtly changes his dialect during the presentation of the facts, Amakasu bursts out and identifies Conan's speech as a bad usage of the Kansai dialect, proving that he is really from the Kansai region.

In addition, while acting as a left-hander, Amakasu is really right-handed, as the arrangement of his dishes easily proves. He had used his right hand to administer the poison to his victim and did not want to end up his own victim as well, even after cleaning his hand with a wet napkin usually served along with ramen (which is the reason why he had ordered ramen while the police checked the crime scene).

As it turns out, Amakasu is responsible for murdering his firm's manager in a fit of rage some time earlier, and Shibamiya, the latest victim, had found out about it, so Amakasu decided to silence him, so he lured Shibamiya to the restaurant toilet and poisoned him.

After Amakasu is arrested, Andre and Jodie Starling examine a photo of Masumi while noting their familiarity with her face. Meanwhile, Heiji reveals his purpose of the visit was to take them to the house of deceased Kohei Wakamatsu after receiving a letter which challenges him to solve the murder.
