Case

Situation

A chef named Shigeru Unagizuka, who is also the owner of Ginpachi Unagi Shop, was injured in the leg and could not make a delivery, so Genta decided to help him. He coincidentally meets Conan, Haibara, Mitsuhiko, and Ayumi on the way. Unfortunately, the chef is discovered to be seriously injured by a stab wound to the left side of the chest and is currently being treated in the hospital in critical condition. This makes Genta extremely angry and determined to make the culprit pay for what he has done.

Attempted murder

Location: Ginpachi Unagi Shop

Victim: Shigeru Unagizuka

Time: Between 3:30 and 4:30 pm

Injury: Stab wound to left side of chest

Suspects: Yuya Kurashima, Hiroyuki Okamoto and Rio Matsui

Before that, Takagi has to ask Genta about the time he last saw Unagizuka, the boy answered he arrived here at 3pm and left to help the victim deliver goods at 3:30pm. Later, the boys also learn that Yuya Kurashima found the victim stabbed at 4:30pm when he delivered soy sauce. In addition, Genta remembers that he met a man who was immediately chased out by Unagizuka when he just left the shop holding an envelope with the word Aoiya written on it, so the police, Conan, Haibara, and the Detective Boys go together to confirm the identity of that person. The man, Hiroyuki Okamoto, had an argument over eel sales outside the victim’s shop. The police also plan to question the last customer who had been to the shop (and luckily they paid by card, so it would be easier to find them) before Unagizuka got stabbed. The last customer, Rio Matsui, recalls that she was at the shop from 3:45 pm to 4:15 pm, and she did not see anyone else suspicious.

At the same time, Genta is hungry because he couldn’t eat the eels he would had after delivering the goods if Unagizuka hadn't been stabbed by someone. Luckily, Rio’s husband would be home late tonight and would be having dinner out, so Genta and his friends are treated to the eels that are probably meant for tomorrow by her. However, when leaving Rio's house, Genta points out something unusual about the eels he and the others had just eaten, so after Takagi leaves, they return to the Ginpachi Unagi Shop to check. There, Genta discovers that the soy sauce used on the eels is different from usual, so everyone decides to ask Kurashima to confirm, and he denies the crime because:

• Ginpachi Unagi Shop stopped using Kurashima's soy sauce since he took over his soy sauce company and if he wanted revenge he would have done it years ago because making soy sauce takes many years.
• Today he went to that shop to let Unagizuka try his newly made soy sauce and saw him stabbed.

Then Genta gets the idea to ask Rio about the eels and who prepared it for her and she says that a very young person wearing a mask made it, and from there, with Genta’s rich knowledge of eels and Conan’s deduction will together reveal the abnormality to point out the culprit.

Resolution

  Show spoilers »

The difference between today's eel, which is the eel purchased by Rio Matsui, and the usual eels is: It was opened from the belly in the Kansai style while the usual eel from that shop would be slit from the back, and the person who prepared the eel was the former chef in the Kansai region and also the culprit of the case, Hiroyuki Okamoto.

There is one crucial piece of evidence that he couldn't erase, the fingerprints on the fan that was used to help grill the eels stolen by him. He tries to run away, but with Genta's determination, it is useless. After the case is over, Conan, Haibara, Genta, Ayumi, and Mitsuhiko visit Unagizuka and he promises to let Genta eat as much eel as he wants and perhaps ask him for help if he needs. He happily agrees with the thought of being able to eat as much as he wants after he helps him.
