Plot overview

Tottori Sand Dunes Mystery Tour (Anime: 801-802)

Yamane and Kogoro meet again.

When Kogoro, Ran and Conan stroll around Kurayoshi in the late evening, they see a police car zooming by with flashing sirens, before stopping in front of a lavish mansion. Yamane and Okamoto just received a call from Shuko Kumado, who reported a robbery at the house. When exiting the car, Yamane recognizes Kogoro and decides to let him help him with the robbery investigation. He instructs Okamoto to first go into the house before filling him in with the case details. Inside, they untie the captive Shuko and Yamane comforts her. Later, Okamoto, Kogoro and Yamane interrogate the suspects and gather information to find the culprit behind the robbery. After learning about the existence of a new suspect in the person of Naomi Senda, Yamane and Okamoto come fetch her and bring her to the Kumado Residence to interrogate her with the rest of the involved people. Despite there being high tension between the Kumados and Senda, Yamane and Okamoto do little to defuse the situation, and Kogoro takes the lead, which hints towards Yamane and Okamoto still lacking long-term experience in tough cases.

Later, the stolen item is returned, which surprises everyone, including Yamane and Okamoto. The two detectives convene with Kogoro to try to dig more information on the suspects and later meet at a local restaurant to discuss the suspects' alibis. They are left stumped when they realize every suspect has an alibi. Later, during Kogoro's deduction, a fictional sequence featuring Yamane and Okamoto comforting the culprit is shown. At the end, the true culprit is arrested at the sand dunes and Yamane thanks Kogoro for solving the case and salutes him.

The Lover Who Vanished on Pont Koitani (Anime: 1190-1191)

This time, Yamane and Okamoto do not meet Kogoro because of a case, but instead because they happen to stay at the same inn in Misasa Onsen. Yamane and Okamoto recently caught a serial robber and rewarded themselves with a stay at the hot springs. Kogoro enjoys the late-night dinner with them, teaching them about how to solve cases, while they eagerly listen. The next day, when one of the inn's employees goes missing, Kogoro directs both of them to help with the search and Yamane dispatches Okamoto to get backup at the Misasa substation. Later, they start searching for the missing person across the prefecture, including at Daisen-ji, a temple at the foothills of Mount Daisen. When he calls Kogoro to give him an update, he jokes to him that he is probably gone off to buy some crab to eat, which he is spot on, but Kogoro does not tell him he is right. Kogoro, Conan and Ran convene to meet with the two detectives at Tottori Station and Kogoro exposes his reasoning. Afterwards, they head back to Kurayoshi where they corner Yasuto Utsubuki, the missing person's boyfriend and force him to reveal that he had planned a fake disappearance with her.

When they head back to the place the missing person is hiding, they do not find her. Going back to the inn to reveal the truth about the hoax, they realize that Sachiyo Yumemiya, the victim, was kidnapped for real this time as they receive a recorded ransom video from the kidnapper. Yamane and Okamoto then coordinate prefecture-wide roadblocks in hopes of stopping the kidnapper. Kogoro later asks Yamane for the piece of evidence found in the place Sachiyo was hiding and matches it to the inn's personalized envelopes, thus revealing that the culprit is among the people at the inn. Following this revelation, Kogoro and the two detectives interrogate the suspects for their alibis, Yamane explaining the timeline for her kidnapping found from security camera footage. They later listen to the recordings from the ransom messages along with the forensics team. After Kazuko Yumemiya, the inn's manager, accepts to give the ransom money, Yamane and Okamoto coordinate with the bank to gather said money. However, Conan and Kogoro then figure out the truth.

At night, everyone gathers to arrest the culprit at Hakuto Beach, where Sachiyo is being held, and Yasuto, Yamane and Okamoto tackle down the culprit and restrain them. Kogoro quickly breaks down the culprit's modus operandi and how they kidnapped Sachiyo. However, when they are about to be brought into the police car, Kogoro is knocked out by Conan. Yamane realizes that the case is not solved and that the real mastermind has not been revealed yet. The real mastermind, once revealed, takes Sachiyo hostage and runs to the shore, and Yamane and Okamoto run after them. After Conan knocks out the weapon from the culprit's hand with his power shoes, Yamane is able to apprehend the culprit.

Relationship analysis

Kogoro Mouri

Since meeting the great detective many years ago when working together, Yamane has been impressed with Kogoro's work and became a big fan, especially since the advent of Sleeping Kogoro. He listens to him religiously and does not hesitate to let him get involved in the investigation. He is often seen nodding when Kogoro makes a statement. In return, Kogoro trusts him and Okamoto to cooperate with him and dispatches them to help the investigation, which he has since taken over. They also have friendly banter between each other, especially shown when they get drunk at the ryokan and Kogoro calls him without honorifics, showing proximity between both of them.

Ryo Okamoto

Depiste their 10-year age gap, Yamane and Okamoto are inseparable sidekicks, working together at all times and even answering in sync. However, Yamane being the superior, Okamoto listens to his orders without hesitation, which shows that he trusts his superior.
