Later, Ran, Conan, Heiji, and Kazuha, go to a sports parlor where Teruaki was last spotted only to discover from the police that Teruaki has been assaulted by an unknown assailant.

It is also revealed that all the suspects have been seen in the hotel after the sauna was closed disproving their previous theory. Conan uses his voice changing bowtie to impersonate Agasa to reveal the one waiting on the veranda was the victim and the Tetsuyuma spotted heading to the sauna was the culprit Junsaku Tansawa in disguise. Conan explains Tansawa tricked the victim into staying in the women's sauna all night in order to see the naked Mishio Natori, the heroine; This is evidenced by the bottle in the dressing room which Tetsuyuma used to stay hydrated and the match cinders used to smoke his pipe. As evidence towards Tansawa as the culprit, Conan reveals that he was completely engrossed in pretending to be Tetsuyuma that he took the silver ring without noticing.

Kogoro receives a request from a letter by Mika Tatezato to investigate the murder that occurred at an inn eleven years ago. On the way, they pick up a teacher named Rokurou Tokobi who requests for them to stop by a grave site before heading to the inn. Tokobi explains that Tatsuhiko Numayama, a student of his, drowned in the river by the inn which is owned by Tatsuhiko's father, Banzou Numayama. They meet Kazuki Araiwa who is paying his respects to Tatsuhiko as it is the anniversary of his death. They are later approached by Banzou who tells them to forget about his sons death. They arrive at the inn and learn that Mika Tatezato is not on the guest list.

They return to the grave site to search for Ran's cellphone.

As Conan investigates, he realizes how the culprit was able to drown Bonzou with swamp water in his own attic. Conan tranquilizes Yamamura and reveals the murderer to be Tokobi. Conan explains combining the water bottle and the paint bottles would be able to carry enough swamp water to commit the crime; The water was then poured into a basin where Bonzou was suffocated in. This is evidenced by the diluted paint that are currently in the containers. Tokobi professes to the murder and exclaims Bonzou ordered his son to disguise himself as a kappa and play in the river in order to attract customers to the inn. Conan clears the misunderstanding, explaining that Tatsuhiko must have done it on his own accord in secret since he burrowed a paint set from Tokobi instead of buying paint himself. Araiwa confirms Conan's deductions, explaining how Bonzou removed Tatsuhiko's disguise as to not shame his son after his death.

They tell Kogoro that they are holding a séance to communicate with Kira Miyahara. During the séance, ghostly signs begin to show themselves and Kira's voice has heard swearing vengeance on her killers. Conan and Kogoro reveal the special effects to be activated by a remote control in Hirasaka's possession.

Hoonogi reveals that he discovered Hirasaka in his room dead. Kogoro breaks open the room and confirms Hirasaka died from drinking poisoned wine. The police arrive at the mansion where Kogoro shows them both locked rooms. In the séance room, Kogoro explains that the front door was padlocked from the inside and the only way out is through high window. The high window can only be opened with a switch in the room. In Hirasaka's room, a small window is found above the door but too small to fit a person through. On the floor of the room were the ripped posters of Kira from the séance room. The keys to both rooms were found in Hirasaka's drawer. The police interview the club members and discover Hirasaka, Hoonogi, and Sawanami have received threatening messages from a fan of Kira and their goal with the séance was to find the culprit. They deduce that the one sending the messages, swapped the recording, is the same person who committed the murders.

Conan investigates the two rooms one last time and brings Kogoro to the séance room and tranquilizes him. Conan reveals that after the culprit killed Hirasaka, he locked the room from the outside, and used one of the giant Kira posters to slide the key back into its drawer and close it before ripping it into pieces and throwing it into Hirasaka's room. As for the séance room murder, the culprit used the remaining posters, rolled them up, and taped them allowing them to support his weight and giving him the support to leave through the window; a rope tied to the poster allowed him to pull it out with him outside the window and its ripped remains are found in Hirasaka's room. He closed the window with the use of Hirasaka's remote controlled appliance. Conan then points out Mifune as the culprit, evidenced by the wine under his necktie. Mifune confesses and explains he was dating Kira before she died.

Later that night, they discover a letter signed by Miyuki confessing to the crime and is at the abandoned cabin. Conan head there and discovers the cabin covered in gasoline and the inugami running towards it. Conan catches the inugami revealing the fire effect was created by imitation fire clothing with remote-controlled lights. The flaming dog-prints were caused by modified lighters placed on the ground and tied to a wire with a hoop at the end. The dog had a mesh-enclosed charcoal tied to its tail, and when passing over the lighters, ignited them. When the dog retrieved the hoop, the lighter came with it, explaining how the lighters were not found after creating the dog-prints. Heiji points out Tomoaki as the culprit, evidenced by the inugami recognizing him as his master, and Satomi's prayer beads.

Masumi answers and pretends to end the call, allowing Conan to eavesdrop on the situation. Conan learns the case of Sawaguri's sister, Miku Sawaguri, was concluded to be suicide when she was found with her wrist slit inside her locked ryokan room. Agasa and the Detective Boys leave to interview the local neighborhood association who were at the ryokan during Miku's death. Conan gradually learns more about the case from information spoken by Sawaguri, the media, and the Detective Boys.

Sawaguri, pleased to have another detective to assist in the case, obeys his requests to take pictures of the hostages' books which were autographed by Miku. During the course of the investigation, the authorities lose the chance to snipe Sawaguri after Ran closes the curtain as she believes Shinichi can find a solution to prevent any deaths. Miku's blog post reveals her last three visitors were from an elephant, a fox, and a rat. Conan explains the animals were based on the hostages' professions: The elephant is Sumika Nihei, due to her husband's seal designs which are similar to an elephant's tusk; Shinobu Yuchi is the fox since she is a baker and her food is colored like a fox's coat; and the rat is Tamami Mitsui whom is a stonemasonry which is gray like a rat's coat. In response, Sawaguri prepares to kill Mitsui.

Conan declares Mitsui is innocent since she was witnessed leaving Miku's room; Sawaguri inferred the culprit crossed over from the balcony and left by his room. As for Miku's death, Conan explains she was mimicking the suicide of the main character in her book. Sawaguri becomes distraught as a result and is taken in by the authorities. Later, Conan reveals his previous deduction was a bluff and that Miku was murdered by Yuchi, due to the fact Mitsui left the room with Yuchi's slippers revealing Yuchi was still in Miku's room after she left. As evidence, Yuchi's book reveals it had been sandpapered to clean off Miku's blood. Yuchi confesses and reveals Miku took all the credit on the book they collaborated on motivating her for revenge.
