Soon after Kaito enters his living room, he sees his nephew lying on the sofa, although this scene looks peaceful, Kaito is anxious because of flashbacks from March, Kaito with a worried voice asks Naoki if he is okay, which he replies that he is just tired and needs rest. Kaito seems to understand Naoki and he is going back to his room.
Kaito is living with Naoki since his older uncle Kiichisaburo was killed in Geneva 5 years ago, unlike Kiichisaburo who abused Naoki, Kaito actually developed a relationship with him similar to that of father and son.
Despite Kaito's cheerful attitude towards people, he is deeply traumatized by the events of 1977 and 1986. He understands Naoki because he was abused by Kiichisaburo as well, after 1977 incident, but his second older brother (Naoki's father) was always supportive towards him. And he controlled Kiichisaburo's anger that he took it out on Kaito, that's the reason why Naoki is very precious to Kaito, Naoki is the only thing left of his older brother, who was murdered in 1986 with his closest family, pregnant wife, younger son and himself.
Naoki went to his school, nothing serious happened, until Kouichi, Mei, and Ayato approached him, Naoki turned his head to their direction.
Naoki: What?
Kouichi: Muneyoshi-kun would you like to join our Christmas party tommorow?
Naoki: Ayato didn't tell you? First of all, I don't want to go there, secondly, I'm busy that day.
Ayato: We thought you changed your mind..
Mei: To be honest I'm only going there because Kouichi asked me to go with him.
Naoki: Ayato, I said it before, I don't have time for it, I'm busy. I don't care to be honest.
Ayato: Oh I'm sorry I thought that you maybe changed plans for today.
Naoki: No and don't bother me again.
Naoki went on his way, he spent the whole day as usual.
When he approached his house Kaito was there, Naoki wanted to ask a question to him.
Naoki: Kaito, are these rumors about our clan true?
Kaito: Which ones exactly?
Naoki: The ones about the fact that after the capitulation of Japan, our clan collected weapons from demobilization and hid them in secret caches in the mountains.
Kaito: Umm, I don't really know much about this rumor, but in my opinion this is nonsense.
Naoki nodded, and went to his room, for his Vicortinox knife, then he went to the old mansion that belonged to the Muneyoshi clan, and after 1977 incident it was abandoned.
Soon Naoki arrived there alone, (or so he thought), he broke out inside and started searching for the answers.
Dried blood from the incident 21 years ago was still visible on the property. The property was not in the best condition, no one had taken care of it for 20 years.
Naoki continued searching until he heard footsteps. He immediately took out his pocket knife and pointed it towards the footsteps, that person was Ria.
Ria: Can I give you a hand?
Naoki: Were you following me?
Ria: Maybe
Naoki: I'm looking for information about secret weapons caches that my clan supposedly left behind after World War II. I don't even know if it's true, but I remember when my great-grandfather's adiutant once told me that, his name was Hiiragi or something.
Ria: I don't know if Hiiragi can be trusted, he's an old man, he could be talking nonsense, but my family also talked about it and I even saw a couple of old Arisaka rifles in my basement. It is possible that Great Clans collected weapons after the surrender of Japan, but no one wanted to fight for our former privileges, everyone wanted peace and freedom. So the case was kept silent, or the witnesses were killed.
Naoki: Anyway do you have something about Misaki Fujioka's death?
Ria: Well , I stole notebook from my brother, but (Ria opened it) the Fujiokas were solvable, at least until your friend died in April. See?
Naoki: Well, then your family is not involved in Fujioka's death?
Ria: I don't know, but it seems like they are not involved in her death, like I said before, my brother might know something more about her death.
Naoki and Ria started searching the whole mansion, soon Ria almost fell into a hole through the damaged floor, Naoki caught her reflexively, but the hole was only 2 meters deep.
Naoki: It looks like a hidden basement, I don't know how, but we need to go down there.
Naoki and Ria used the furniture that remained there to use it as a ladder. After a coupe of minutes they finally descended to the basement.
They kept walking through the corridor until they reached the door, Naoki used his swiss knife to break in, he opened it, but the door. The door didn't open all the way, it was still chained from the inside
Naoki: They were closed... on both sides?
Ria: This chain looks rusty and could be easily destroyed with the right tool.
Naoki tried to destroy the chain and door by force by kicking it, but he is not that strong. Soon Ria joined as well, together they somehow broke the padlock and chain. They went inside and Naoki turned on his flashlight, What they saw was a skeleton with a katana in its chest, and a letter next to him, there was dried blood all over the room and some documents. Naoki took the letter and read it. Ria felt like vomiting. *[The letter will be separate from this part]*
Naoki seemed angry after reading this letter. And he started looking for the informations about alleged weapon caches from 1945.
Naoki also saw some family photos of his father, Kiichisaburo and Kaito from 1977, after Kaito graduated from Yomiyama North, after 5 minutes Kaito saw somehing interesting, a crumbling letter to his grandmother Kaguya Muneyoshi from 1950.
The letter:
**guya-sama, everyone who t*ok part in hiding the weapons ca****
** dead, according to your orde*s, however, we also had to kil* * *esident of the villa*e of Yamegawa, it's terrible, but the safety ** *ur clan is now ce***in, the cache is cov**ed with earth and a few pine trees are planted around it, I'm not sure not sure if we will ***
these **apons in the future, ho**ver, these pine t*ees were plante* *n the oak forest, wh**h can distinguish it, these wea***s are not lost.
Naoki: So it's true, It's not just a conspiracy theory, according to this letter the cache is somewhere near Yamegawa village, we can go now.
Naoki and Ria, left the abandoned building, Naoki looked at her and he decided to lend her his pocket knife.
Naoki: I know the streets are safe, but take this just in case, but give it back to me tomorrow
Ria: But why? I mean I appreciate it, but I doubt anyone would raise a hand against me.
Naoki: Just in case
Ria: Oh, okay.. thank you I guess?
Ria and Naoki went to their homes after it got dark, Naoki wondered whether to tell Kaito the truth about the 1977 incident.
"He shouldn't know, he still has good memories of my father," - he thought.
Kobayashi met with people who were in debt to the Hironiwa clan, they decided to attack someone from the Hironiwa clan.
Meanwhile Ria met with her friend Yuuna, she was there until midnight, she was going home now, soon she noticed that she is followed by two men. She entered a dark alley where she bumped into Kobayashi.
Ria: Oh I'm sorry officer.
She tried to walk awal but Kobayashi blocked her path, soon the two men approached her, they started closing in with a crowbar and a baseball bat, Ria pulled out the pocket knife Naoki had lent her, and she managed to stab the man with a baseball bat, the second man hit her arm with a crowbar, breaking her bone, but she stabbed him as well, soon Mr. Fujioka arrived from her back and stabbed her neck with a kitchen knife.
Ria died immediately, the two men were still alive, but severely injuried, after a while, Fujioka realized what he had done. He knelt down, he felt disgusted by his action.
Kobayashi approached him.
Akira: You're doing this for your daughter, aren't you? You shouldn't back down just because your hands get dirty, you're doing it for her right? Believe me, it was necessary, and now...
Kobayashi fired from his pistol at two men who survived, later he gave gloves to .
Kobayashi: We have to clean it up somehow...
was trembling when he carried Ria's body to nearby trash bin. After they did that they fleed from the crime scene.
Fujioka: K-Kobayashi-san I-I thought that we were only going to intimidate her.
Akira: If she survived, her clan would know about it, we would all be dead.
Fujioka took a deep breath,
Fujioka: But why did you kill these two?
Akira: If they survived they would have led to us, they were injured which meant they could have led the police to us through them. I had to kill them.
Fujioka: But why did you use your service weapon? This would lead the police even more to us, or more precisely to you officer.
Akira: Service weapon? (Kobayashi laughed) No, it's private.
Fujioka: Private?
Akira: Correct.
Fujioka: The only reason I'm working with you is because of my daughter, but I wonder what benefit you get from it?
Akira: You will find out in due time.
Kobayashi and Fujioka went to their houses. When Akira entered his house he pretended like nothing happened, his daughter and stepdaughter were already asleep, he just entered his house like a ghost.
The next day, Kobayashi goes to the crime scene again, this time as a policeman, he arrives at this dark alley where the bodies of two men are lying, soon Seiji Ota opens the trash can where he discovers Ria's body.
Ota is a young policeman, not yet used to such sights, Ota turned pale.
Keitaro: You should get used to such views, or even worse, or give up if it disgusts you Ota-kun.
Seiji: It's not about that, I mean how they treated her body, throwing her into the garbage, depriving her of her dignity.
Soon, Kobayashi joined Ota, Matsuda and other policemen
Kobayashi: That's because those men were probably indebted to the Hironiwa clan, I think they tried to kidnap the girl, but they failed, they accidentally killed her, and then someone from her clan probably shot her.
Then Detective Chigusa Nomura appeared out of nowhere, she is a woman similar in age to Kobayashi, she came to the crime scene with a cigarette in her mouth, and tired eyes that she usually has.
Chigusa: You are wrong, the victim had no bodyguards. The version in which the perpetrator first killed Hironiwa, then his partner and finally himself is senseless, so the only logical explanation is the existence of a third perpetrator who ordered the entire operation and then killed his accomplices. It had to be a person with access to weapons legal or not.
