"D - do you know who is the culprit?!" Misao looked at him with a surprised expression.


    "Yeah, I have solved the case," Yuuki nodded.


    "Really, Onii-Chan, who is it?" Ayumi asked.


    "Do you really know who it is?" Conan asked him curiously.


    "Yeah, if I''m not wrong both of the culprits and the weapons are still in this house," his answer made everyone startled.


    "Wh-"


    "What?"


    "Really? Where is it?" Misao asked. He didn''t have an unpleasant expression since it was his idol. He would have a different expression when it was Agasa or Conan who would exin it.


    "But before that, Agasa Professor, your hammer is gone right?" Yuuki asked.


    "Ah, yes, my hammer was gone earlier," Agasa answered.


    "Hammer was a blunt object and the victim was killed with a sharp object!" Misao interjected.


    "I knew that I didn''t mean the killer using the hammer to kill the victim, rather the culprit using a hammer to transform a certain object to be a weapon," Yuuki said.


    "Certain objects? What is it?" Mitsuhiko asked.


    "It''s the obsidian," Yuuki answered.


    "OBSIDIAN!!"


    "Obsidian was used as a weapon from the ''Jomon Period'' and the culprit broke the obsidian with the hammer to get sharp fragments to kill the victim," Yuuki exined.


    "He probably made that weapon during the night before the rain and in quite a far ce to not make a lot of noise," Yuuki exined.


    "Hmm," Misao nodded while writing his note.


    "So? Who is the culprit?" Haibara asked.


    "He is the one who could tell the obsidian with one look," Yuuki looked at him and said, "Adachi Raito-San, it is you!!"


    "Wait for a second! How can I be a murderer with only the knowledge of the stone?" Adachi asked and added, "If it is only the obsidian then both Fuuga and the olddy must be known about it as well, why should it only be me?"


    "Because of the shoes," Yuuki exined.


    "Sh - shoes!!!" Adachi was surprised.


    "If I remember correctly you said that you heard the scream of Akane-San and you rushed toward her side in a hurry, you know that you need to hurry in this situation but why you need to wear your shoes firmly, and what''s more, you tied theces of your shoes very properly, it doesn''t make sense," Yuuki said.


    "In other words, you were there not because you were very fast but because you were there from the beginning," Yuuki said.


    "Still, you can''t conclude that he is the culprit only with the shoes," Misao said.


    "Of course that is just the trigger that made me suspect him, the decisive evidence is the hammer," Yuuki exined.


    "Hammer? But we didn''t find any fingerprints on it," Misao said.


    "If it was someone who was familiar with the house such as both Fuuga and the olddy, they would use something from the toolbox and not steal something from Agasa," Yuuki exined.


    "Fuuga?" They were startled.


    "Oh, I forgot to exin that he is the grandson of the olddy," Yuuki exined.


    "WHAT!!!" Everyone was surprised.


    Fuuga who was known suddenly became ufortable. He knew that he had told his grandmother to be a chef in town but here he was bing hosts and did stic surgery.


    The olddy had noticed him for a while but he didn''t say anything.


    "B - but where is the weapon?" Misao asked the most important thing.


    "The weapon should be inside the aquarium and Adachi touched the aquarium as you were heading to the bathroom to wash off her blood. So it was most likely back then when you put it inside the aquarium," Yuuki said.


    "In other words, the weapon should be there, so I guess he didn''t have time to clean his fingerprints and Akane-San''s blood," Yuuki said.


    Adachi shook his head and sighed.


    "What do you say?" Misao looked at Adachi.


    "Yes, I''m the one who killed her, that woman, she took everything from me," Adachi said with anger. He said that he didn''t want to be a host but he needed to pay his parent''s debt to her parent. He had almost finished paying the debt only that woman didn''t want to let him go and increased the debt. He was an old fashioned man and couldn''t see himself being under a woman. He decided to kill her with an old-fashioned weapon.


    The police didn''t say anything and brought him to the police station.


    Yuuki had also seen a drama between Fuuga and his grandmother. He knew that Fuuga was lying to his grandmother telling her that he had be a great chef in the town. But he had been lying to her since had had stic surgery and became host but the knife with a red handle made him realize the dream that he had buried inside his heart.


    Fuuga welled in tears while holding the knife.


    Yuuki wanted to go back but stopped by Misao since he had asked him to take a picture with him.


    "Say, cheese!!!"


    "CHEESE!!!"


    Everyone also took a photo together in this mountain, though, it wasn''t a good memory but it was still a great photo.


    Yuuki was on his way to him and felt quite great since he had beaten Conan.


    "How did you know where the weapon was?" Conan asked.


    "Ayumi who was the one telling me about it, she was very helpful to me, thank you, Ayumi," Yuuki said.


    "Hehehe," Ayumi smiled happily while looking at him.


    "I should call the police right now so you won''tmit a crime," Haibara said.


    "WHY???" Yuuki looked at her with a perplexed expression.


    They started tough together and went home. They felt tired and slept on the way leaving him alone driving.


    Yuuki felt that it was better to go on a trip with girlfriends next time. Though he remembered that he had promised to go out with someone for ramenter. He was on his way back only to see an old man with a weird head shape on the street on his way back.


    Yuuki smiled at him and this old man was also smiling at him. He felt that old man wasn''t a human rather someone from a supernatural world.


    "Yuuki, did you see someone?" Haibara asked.


    "No, it is just my imagination," Yuuki answered.


    The old man looked at his car and smiled. He had met someone interesting. He had used his youjutsu to hide but that young man noticed him, ''Interesting.''


    "Leader, what''s wrong?"


    "No, how is Kyoto?"


    "As expected a group of humans kept attacking them, do we need to help them?"


    "No, Yasaka should be able to handle it herself, anyway, let''s go back, I want to see my grandson."
