Although all the suspects have video clips serving as their alibis, Shinichi figures out that Naho Ojiro is the murderer. He noticed that it was strange for Naho Ojiro to take a clip vertically, since it would be hard to film long fish, like sharks, in their entirety. Moreover, no one seemed to avoid walking into the camera frame, as if they had not noticed the camera. This is because Naho hid the phone on her boyfriend's white cap without him noticing.

The evidence is the blood on her hand covered by her glove. While she used a plastic bag to prevent blood splatter when stabbing the body with the knife, the bag did not block all of the blood, and some of it had seeped onto Naho's glove. So, she had to reverse her gloves inside-out, but this changed the color of the gloves. Shinichi noticed this color change after seeing the photo that Naho took with her boyfriend.

Motive

Kunihiro was blackmailing her by threatening Naho that he will leak nude photos of her to her current lover, family, and workplace to humiliate her unless she pays him.

Aftermath

After the case, Shinichi and Ran were walking in front of aquarium and talking. It started to rain, prompting Ran to put her hood to her head. Unfortunately, Ran's phone fell from her hood into a nearby drainage grate. Shinichi forgot to tell her that he placed it there after testing how the culprit did the trick. Shinichi promises that he will buy a new phone for Ran, but after seeing that Ran is still upset, he suggests that they visit Tropical Land. Ran adds a condition: She will only forgive him after paying for all their expenses at their Tropical Land visit, assuming she wins the next karate tournament.

Trivia

• Nazo is used as an insert song during the scenes where Shinichi is walking around Tropical Land.
• Starting this episode, the door eyecatch has been updated to be a combination of CGI and 2D animation. A new Next Conan's Hint design is also introduced, featuring a remake of the first version of next episode title card with the addition of Ai Haibara.
• This is the third time that a case has been adapted for a second time in the anime, with the last being The Moonlight Sonata Murder.

  • Your Best Friend (chosen by Minami Takayama)
