The next day, Akira and Sakuya entered Ayato's house.

They talked to his parents.

Akira asked where Ayato got the cyanide capsule.
Azusa and Soichiro replied that they had no idea, suspicion fell on Yuka.

Kobayashi asked if Ayato's relationship with her sister was good, and if Yuka was interested in dark things - occultism, black magic, or if she also read books with dark themes.

Azusa became angry, according to her it was absurd to suspect Yuka because Yuka was at her university, and there was no way that Yuka poisoned Ayato.

Akira: So, I think we should assume that there is someone who wants to destroy the Great Clans, communists? competition? yakuza?

Soichiro: JRA? Chūkaku-ha? Here? In Yomiyama? I don't think so

Azusa: Can you stop putting forward such absurd theories Officer?

Akira: Absurd? How else can you explain your son's suicide?

And with a cyanide capsule... It looked as if he wanted to kill himself at all costs. He had tried to hang himself the night before, hadn't he?

Azusa: I don't know why he wanted to do this. In his farewell letter to us, he wrote that he was overcome by death. That he prefers to die before being lonely.
He suffered from schizophrenia. But on a daily basis he was quite cheerful. Until that day...
Sakuya remembered that the only person Ayato talked to right before his death was Kobayashi..

She thought Kobayashi might be involved in his suicide.

Sakuya took down Soichiro and Azusa's testimonies, and when Akira left, she told them not to trust Kobayashi because he often uses lies and manipulation to conduct investigations.
Sakuya began to wonder more about Kobayashi, he wasn't from here. However, during questioning, he seemed to know many people from Yomiyama.
It was so suspicious that she decided to ask Chigusa for help.

After work, Sakuya drove up to her house.

Even though Chigusa is 43 years old, she has never had any relationship. She had lived alone for 22 years.

Sakuya knocked on Nomura's door.

Chigusa opened the door.

Chigusa: What?

Sakuya: Nomura-san… I have some suspicions about Kobayashi...

Chigusa: And who wouldn't?

It is unclear whether he is lying or telling the truth.

If he was grilling that boy with Anju, he probably destroyed him mentally and he couldn't stand it.

Sakuya: I remembered something Nomura-san...

Sometime in November, Kobayashi helped Fujioka, one of the debtors of the Hironiwa clan.

Chigusa: Huh? Interesting..

Sakuya: Maybe it's stupid... but... but maybe Kobayashi is related to the death of Ria and Kenshin Hironiwas.

Chigusa: But where would he get the Mauser C96?

He probably wouldn't be able to afford such a weapon on his salary... and besides... he would probably have to register it somewhere.

Sakuya: Sorry... you no longer work for the police since you became a private detective.

This shouldn't concern you...

Chigusa: It doesn't matter, on the contrary. I'm going to hang around Kobayashi, maybe I'll learn more about him.

Sakuya: Thank you for your help... And sorry for the intrusion.

Chigusa: If that's all, you can go now.

The next day, Akira went to Yukiyo's store with his daughter.

Ayane was looking at the dolls, Kobayashi didn't know that Nomura entered behind him in disguise.

Akira: Ayane.. I don't think these dolls are intended for children, they look rather artistic.

Ayane: This is what I would prefer... These are different from the ones I usually have, and I'm not thinking about a toy, but about a decoration...

Akira: You are very mature for your age Ayane..

(Akira smiled)

Yukiyo was walking near the store, she noticed Kobayashi out of the corner of her eye, she came closer and looked at Kobayashi.

This was noticed by Nomura who was following Kobayashi.

Chigusa continued to pretend to look through the dolls.
After some time, Ayane also noticed Kirika staring at Kobayashi.

Ayane: You must be the creator of these dolls, right ma'am?

Yukiyo: Correct

Yukiyo turned her face to Akira.
Yukiyo: Excuse me do we know each other?

Akira: I doubt it, I've been living here relatively recently.

Yukiyo: Will you be buying anything?

Akira: Probably yes.

Ayane chose the doll, Akira and her daughter left the store, Amane, Kirika and Chigusa remained inside. Chigusa walked up to Kirika

Chigusa: Excuse me, do you know the man who just left?

Yukiyo: No

Chigusa: Are you sure?

Yukiyo: He reminded me of someone from the past... But I guess that was just a mistake.

Chigusa: Can you tell me who he reminds you of?

Yukiyo: I don't want to talk about it... It's old times

Chigusa: I'm investigating the murder of Ria Hironiwa, and your testimony could be very valuable.

Yukiyo: Hasn't it been stated that it was her father who killed her and her brother?

Chigusa: Okay, I'll admit it. I'm conducting this investigation on my own, I hope I can still count on you to help me.

Yukiyo: I doubt my memories will help.

Chigusa: Nevermind, please speak.

Yukiyo: This man reminded me of Shion Muneyoshi, his daughter had eyes identical to his, although his eyes were blue, not green like Shion's.

Chigusa: Shion Muneyoshi right? Hmm, it's quite possible he's still alive.

Yukiyo just didn't say anything.

Chigusa: His body was never found, and in 1988 the archives at the police station were set on fire. Do you remember that?

Yukiyo nodded.

Chigusa: So, it's possible we're dealing with Shion Muneyoshi. Then even the motives would match... Thank you for your time.

Chigusa left the store, meanwhile Naoki returned home. He was ignored at school all day, just like Mei was ignored, however Mei and Naoki communicated with each other through notes.
Naoki intends to visit the Hiiragis the next day to see if they killed Fujioka.

Naoki entered the house, Kaito greeted him and told him that he remembered something.

Kaito: I remembered something from the day your friend died Naoki..

Naoki: Then speak up.

Kaito: One of the nurses was blocking my passage, ahh Mizuno-san, I feel sorry for her...

Naoki: Is she alive?

Kaito: Unfortunately no, she died in an elevator accident.

Naoki: Whatever, Did she have any rational reason to block your passage?

Kaito: She said the floor was washed... but it wasn't...

If I wasn't so devastated, I probably wouldn't have listened to her... maybe I would have saved your friend...

Naoki: Mizuno? I think one of the idiots in my class has that name...

Kaito: So she died because of a curse... Naoki, what are you going to do about the fact that she had a brother?

Naoki: I'll ask him a little... nothing more

Kaito: But you won't hurt him, right...?

Naoki: Maybe..

Kaito: Naoki! do you have any morals?

Naoki: "if an injury has to be done to a man, it should be so severe that his vengeance need not be feared" – Machiavelli.

Kaito: Kiichisaburo raised you to be a monster...

Naoki: I was joking, however...
If Mizuno won't talk, I will force him to do so

Kaito: I don't think I can stop you... But please don't be cruel to him...

Evening came, Naoki was waiting for Takeru near his house, from what he heard today, Takeru met his friends today. After 10 minutes of waiting, he noticed him, took his hand and kicked him in the sensitive spot.

Takeru: What the F*CK?

Naoki knocked Takeru to the ground and looked him in the eyes. The veins in his right eye had enlarged and the markings on his eyes had increased.

Naoki: From now until you fall asleep, you are under my control.

Was your sister Sanae acting suspiciously in early April last year?

Takeru: Yes, she acted like she was possessed or under hypnosis. She seemed sadistic during that day... I don't remember what day of April it was exactly... I was afraid of her back then. However, the next day she didn't remember anything.

Naoki: Was she dating someone?

Takeru: No, but the day before my sister started acting strange she was interrogated by the policeman. Supposedly she was a witness to some crime... But I doubt it.

Naoki kicked Takeru in the head. Takeru fell into the snow, losing consciousness.

Naoki was furious, rational options were gone. His father - Shion Muneyoshi is still alive, under a different identity.

Naoki was returning home, he sat on a park bench and took out a syringe with morphine that he had stolen from his uncle when he was in the hospital.

Mei, returning from Kouichi, noticed that Naoki was going to inject the drug into his vein.
At first she just sighed and moved on, but after a long moment of thought, she ran up to Naoki and punched him in the face and grabbed the syringe from his hand.

Naoki: Oh… Mei it's you…

Mei: What were you going to do?

Naoki: All rational options can now be thrown into the trash, I had to drift off for a moment to accept that my father was actually alive all along... And that he most likely also killed my brother, mother and unborn sister.
It's probably too hard for you to understand. For me too, but I wanted to understand it.

Mei: So you wanted the person Misaki loved to be just a junkie?

Naoki: I wouldn't call myself a junkie.

I have never taken drugs of my own free will.

This was the first time I decided to take them of my own free will.

Mei: Did someone force you to do this?

Naoki: I don't want to tell you my past...

Mei: Why?

Naoki: I don't see the point in telling you this

Mei kissed Naoki.

Mei: And now?

Naoki: You just did it for just a few words?

Mei: No, you just seem like someone who understands me much more than Sakakibara..

Naoki: I think that if I tell you this, you will either not believe me or you will stop considering me as a person who would understand you.

Mei: So, go on..

Naoki started telling Mei his past….
