After lessons, Ayane and Rika met Isamu Takatsuki and Yuuko Murata on their way.
Isamu waved to them.

Isamu: Hi Kobayashi-san, and Fuyutsuki-san

Ayane: Hello

Rika: Hi

Isamu: What are you guys doing here?

Ayane: We just prefer to take a longer walk...

Yuuko: It's in a completely different direction from your homes.

Rika: Have you heard of the "house of death"?

Ayane: Rika!

Isamu: In my and Murata-san's neighborhood, a lot was heard about him.

Two people were reportedly killed there in 1999 and also the dismembered corpse of a 3-3 class student was found there in 2004.
It is said to be haunted there.

Yuuko: Are you afraid, Takatsuki-kun?

Isamu: What? Me? Of course I'm not afraid!

Yuuko: In that case, why don't we go there together with Kobayashi-san and Fuyutsuki-san.

Rika: All in all, it would have been better off in a larger group...

Isamu: Of course! Let's go!

Upon arriving at the site, it turned out that the door was locked.

Isamu: The doors are closed, Are we going back, in that case?

Ayane: Let's try to go through the window

Rika found an ajar window, everyone went inside and started exploring.
The living room still had dried blood stains, and the wall had two inscriptions "1999" and "2004."

Suddenly everyone heard footsteps, Isamu was terrified and tried to run out the window.

Yuuko, Rika and Ayane kept their cool.

Rika: Do we have anything to defend ourselves with?

Ayane: We can break the plank out of the floor

Yuuko: Let's wait, maybe he'll go away.

Isamu broke a window during his escape, the mysterious person focused his attention on the girls.

Isamu: Yuuko! Kobayashi-san!, Fuyutsuki-san! I'm so sorry! Run away!

Ayane was carrying a piece of board from the floor, the mysterious person got close enough to them.

Ayane was about to strike the person before she froze

Ayane: Naoki?

Naoki: What are you doing here?

Rika: Ayane , you know him?

Ayane: That's my brother

Rika: Indeed, good morning Mr. Hiiragi.

Naoki: My name is not Hiiragi but call me what you want.
However, answer my question first.

Ayane: We were just bored.

Naoki: Do you realize how many people have been killed here?

It's dangerous here, especially for you 3-3 class students.

Rika: Before we leave, may I ask you a question?

Naoki: Just make it quick

Rika: Who else besides Mrs. Sakakibara can remember how to lift the curse?

Naoki: Probably none, except the extra.
It is possible that they may remember the events of the past calamities

Ayane: Huh?

Naoki: Can you see these inscriptions?

I have a theory that they were written by the same person, but it's just a theory.

Ayane: "1999" I "2004"?

Ayane saddened after realizing some fact

Rika:"2001" or "2002" are missing

Naoki: This is precisely the argument that undermines my theory.

It is possible that the 2004 extra can influence telepathically or partially assimilate with the extra.

And so on with other extras.

Ayane was relieved

Yuuko: Kobayashi-san are you okay?

Ayane: Yeah just….

Naoki walked to the front door and opened the door.

Naoki: You can leave now.

Rika: Okay, we are sorry for the intrusion.

Naoki: No harm done, just don't do it again.

After leaving that house, Isamu ran up to the rest.

Isamu: Kobayashi-san!, Murata-san! , Fuyutsuki-san! Are you okay?!

Ayane: Yeah, everything is okay.

Isamu: I saw him for a while,
Who was he?

He did not have one eye nor right arm...

Ayane: Well…

Rika interrupted Ayane

Rika: Was it the murderer you know?

He said either we get out of here or he'll chop us up alive

Isamu: Really? It's really disturbing.

Ayane giggled a bit

Isamu: Are you guys making fun of me?

Yuuko: You'll believe anything they tell you to believe, you've always been like that.

Ayane: Murata-san, did you and Takatsuki-kun know each other from before middle school?

Yuuko: We live almost next door to each other, went to kindergarten and elementary school together.

Yuuko recalled an important thing.

Yuuko: I just remembered something, I think it made me vote for Ai in April as a non-existent person

Rika: Please tell us.

Yuuko: Isamu, do you remember Hiiragi-san when we were in the kindergarten?

Isamu: I don't remember much from that period, but I think we went there with Nae didn't we?

Yuuko: Exactly, and Ai?
After all, they are twins, it's a wonder they didn't went there together.

Rika: So is Ai or Nae the extra ones?

Ayane: It seems so, but how to prove it?

Rika: I shouldn't spread the word, so Isamu please move away further.

Isamu: Huh? But why?

Yuuko: Everyone knows that you like to gossip and spread things.

Isamu: No, it's not true.

Ayane: Despite the fact that you have apologized to me a few times already, I still remember the fact that you spread who my father was...

Isamu: I'm really sorry Kobayashi-san, I won't spread it anymore, really!

Rika: Takatsuki-kun, please.

Isamu: Fine…

Rika: Listen, Nae wasn't really seriously ill for a month, she actually ended up in a psychiatric hospital.
It was supposed to die in June, don't you remember her bags under the eyes back then?
The nearest psychiatric hospital is 30 kilometers from Yomiyama.

It is true that it falls under the Yomiyama hospital, but it is located outside it.
That's probably why Nae survived June

Ayane: So is Nae just mentally ill?
If so, why she was already released ?

Yuuko: Her mental illness was caused by a curse...
So as soon as Nae left Yomiyama, she started to get better.

Ayane: The problem is that Nae doesn't act like a mentally ill person, she is composed.

She's trying to finish off Sakai by destroying his psyche and forcing him to commit suicide, which is what she told me herself.

Nae Hiiragi is about to kill Kento Sakai and Hiroya Takana.

Rika: Wait what?

Ayane: That's why I asked you if you were terminally ill, Nae tried to manipulate me.

Isamu: How much longer?
Hey I'm waiting for you!

Yuuko: You can join us.
We are going now.

Under the cover of darkness, Kouichi got into Naoki's car and they drove to the house where Shion was killed in 1999.

Kouichi waited in front, after some time Naoki brought the guns.

Naoki: Sakakibara remember, you are doing it for your family, so keep your cool and don't panic.

Kouichi: I feel the same as I did 9 years ago

Naoki: Did you kill anyone then?

Kouichi: Yes… No…. Wait, I don't really know

Naoki: You probably tried to forget or...

Kouichi: Or?

Naoki: You killed the extra one.

Kouichi clutched his head as if a memory was trying to force its way into his head.

Naoki got out of the car for a moment and lit a cigarette, when Kouichi calmed down he returned to the car.

Naoki: Did you remember?

You know, I have a sister who goes to this class, it would be quite useful.

Kouichi: I want but I can not. As if this memory had never existed.

Naoki: Nevermind.

Muneyoshi had driver up to the Shinozaki estate.

Kouichi: Where are we?

Naoki: Toujurou Shinozaki's estate.

You see?

He is having a meeting, among his guests are 4 people from the Yomiyama branch of the Hironiwa clan
They are our target

Naoki pulled out Joker masks and balaclavas

Naoki: Put it on
We're about to start.

Naoki and Kouichi in disguise approached the door to the yard and opened fire.
Some tried to return fire but failed.

Naoki went inside and started killing off members of the Hironiwa clan.
One of the survivors noticed this. And she said to Naoki.

Woman: Don't shoot at me, I'm not your target.

Naoki: How do you know?

Woman: You only kill members of the Hironiwa clan, right?
Look, if you do anything to me, you'll involve the Minamiyashiki clan.
I think I know who you might be.

Naoki: First introduce yourself.

Chitose: Chitose Minamiyashiki.
You ruined my business, Muneyoshi.

Naoki: There are no cameras here?

Chitose: No

Naoki took off his balaclava and mask.

Chitose: Just as I thought
I won't say anything, but I want compensation for interruption of business.
You can't kill me unless you want to involve the entire Minamiyashiki clan.

Naoki: Fine, how much?

Chitose: 40 million yen, or give me a chance to earn at least the same amount.

Naoki: You're welcome, but give us the details of your business.

Chitose: It was a completely legal investment, new apartments, we were to buy them at a low price from the current syndicate that owns them.

Naoki: The Anju-Misaki-Hiiragi syndicate?

Chitose: Yes, Osamu Hironiwa and Toujurou Shinozaki intimidated Koutarou Misaki and Sachio Hiiragi into selling their shares at a favorable price.

My role was to peacefully convince Mahiro Anju to agree to such an arrangement.

Kouichi: Wait
Did they intimidate Koutarou Misaki?
Was killing his daughter intended for this purpose?

Chitose: I don't know, I wasn't in charge of it.

Chitose pointed her finger at the bodies of Toujurou Shinozaki and Osamu Hironiwa.

Chitose: Ask them not me.

Naoki: One more question, will anyone be after us after what we did?

Chitose: If you don't kill me? Nobody then.

Naoki: Deal then.
