Naoki called Mei and Kouichi and told them that Akira Kobayashi turned out to be Shion Muneyoshi.

They canceled the meeting and arranged to meet in the old library.

Naoki was also questioned by police.

He brought Norisuke's old suicide note from 1977. Kaito was still Shion's potential accomplice, but he avoided arrest.
Shion disappeared like a drop in the ocean, but the technology of the time and the importance of the case meant that Shion was wanted throughout Japan.
He was a serial killer after all.

Police have reviewed the cause of death of Chiemi Kobayashi in 1997.

Yuuna testified about her mother's condition at the time, everything pointed to ricin poisoning.

However, death occurred too early.

In fact, Chiemi found out about her husband's two identities, Shion, wanting to avoid this discovery, strangled Chiemi, her death looked as if she was struggling with an illness.
However, Yuuna decided not to tell her sister this, and she took care of her from then on.

Ayane was concerned about where her father went, Ayane didn't believe that Akira/Shion supposedly stayed at work longer.

Yuuna, wanting to avoid more trauma for her sister, lied to her that her father had run away with some woman from them.

Yuuna hugged her younger sister, the real reason for Ayane's abandonment by her father would remain a secret.
The police agreed to keep Shion's false identity secret in order to avoid a scandal.

All evidence that Akira Kobayashi worked at this police station was secretly destroyed.

The publication of Shion Muneyoshi's case affected Naoki's reputation at school, although he was still considered a non-existent person.
During chemistry class, someone "mistakenly" poured formic acid on his hand.

Naoki took advantage of his "privilege" of non-existence and punched his bully straight in the stomach.
Naoki managed to wash the formic acid off his hand in time, but he still had burn marks from it.
After class, he met up with Mei and Kouichi.

Naoki: So what do we do?

Kouichi: Your father may have already fled the city.

Naoki: He would have to flee the country, his case would gain a lot of publicity due to his other crimes.

Besides, I wonder if he is responsible for the death of my mother and brother.

Mei: We can also take into consideration that he will want to hide in Yomiyama for some time...

Naoki: Even the Hiiragi won't give him shelter.

Especially since he killed Tōkichi's son.

Kouichi: Tōkichi Muneyoshi? I've heard about him somewhere...

Naoki: I don't want to brag, but he was a general of the Imperial Army.

In 1945, he committed hara-kiri, and his adjutant - Kiyoshi Hiiragi - wanted to do it with him. Kiyoshi was still young, and my great-grandfather ordered him to continue living.

To this day, the Hiiragi family is grateful to my clan, they will probably help us in case of emergency.

Mei: It's possible that Shion will try to stay at my house, If he had a serious connection with Kirika in the past, he would try to get back to it.

I feel like I might die soon.

Naoki: Mei, come here for a moment..

Naoki and Mei moved away from Kouichi, Naoki began to whisper in her ear

Naoki: You know, back in those forests near Yamegawa, remember when I got lost?

Mei: Yes I remember that.

Naoki: I have access to a guns, I can give you one for self-defense against Shion.

Mei: What did you need them for?

Naoki: It's a secret, but let's assume I end up using them against Shion.

Mei: Who was your first target?

Naoki: I'll tell you later, I will have to use my ability on Kirika, if I had two eyes with the same ability I could use it more often.

Unfortunately, each use damages my eye more and more, and eventually I will have to wear the eyepatch permanently, just like you.

Mei and Naoki returned to Kouichi.

Kouichi: I'm sorry, but am I even considered by you in this matters?

Naoki: Mei told me about the events of July, you would not be fit to kill a living person, but you will be useful to me in another way.

Kouichi: Did I...kill someone?

Mei: What's more, your own aunt.

Kouichi: Well, my aunt was a teacher at this school in 1996. So she could have been an extra person in previous year.

Naoki: Sakakibara, you remind me of Ayato sometimes, Both you and Anju wouldn't hurt a fly, But in a crisis you know how to kill. I don't think you did anything wrong Sakakibara, on the contrary, by killing your aunt you saved the lives of the rest of the students.
I wouldn't even want to get involved in saving this class if I wasn't poisoned, I would just care about myself.

Mei: Well, as a previous non-existent person I had a similar attitude, I knew from the beginning that Mikami-sensei was an extra person.

However, no one would believe me, and I had no idea that an additional person had to be killed to break the curse.

Naoki: Seriously?

I even figured it out before the curse.

Mei: You know, Muneyoshi-kun, we were both the loneliest people in our class, but I had a neutral attitude towards our class and you were quite hostile.
The first thought I had was not killing the other class members, but surviving myself.

Kouichi: I on the other hand , ever since I found out about the curse, I thought about saving everyone...

Naoki: Sakakibara, I have a question for you.

Kouchi: Yes?

Naoki: Would you rather Sakuragi or Akazawa survive?

Kouichi: I wanted everyone to survive...

Naoki: I will repeat the question,

if you had to choose….

Kouichi: What is that question?

And so Akazawa-san and Sakuragi-san, Kazami-kun, Ayano-san, Takabayashi-kun and Mei's sister had to die.

Naoki: Second part of the question:

Who would you like to die first during this curse? Name even one person.

Kouichi: If this meant that the rest of us would survive, I would kill myself.

Naoki: Let's assume that someone else would die in Misaki's place, for example, if Kubodera was killed before Misaki died, would it be possible to kill two birds with one stone?

Mei: Do you think this would work?

Naoki: It works, after all, thanks to Ayato poisoning Misaki, I'm still alive.
Sakakibara, If you had also thought of it, maybe the massacre would have been avoided, I don't know who was responsible for it, but by killing the people responsible, your friends would survive.

Kouichi: Muneyoshi-kun, if you started killing like that, you would end up like your father...

You should value human lives more.

Naoki: I have seen the value of human life - none, if you want to defeat evil, you have to become a greater evil.
Just like you did.

Mei: In that case, me and Muneyoshi-kun are going to Yamegawa, besides, I have a favor for both of you.
Basically, this would be our chance to kill Shion.

Kouichi: Of course, Mei, what would you like from us?

Mei: Would you like to spend the night at my place?

Just don't imagine anything more (Mei and Kouichi blushed a bit, Mei had a slight crush on Naoki and Kouichi on Mei, even though they agreed to remain friends for now)

Naoki: So be it.

Kouichi: I'm in too, then.

Naoki and Mei went to the forest near Yamegawa to get weapons, Kirika, who was under the influence of Naoki's abilities, drove them, she had no idea what she was doing.

Kirika went to a doll exhibition.

Kouichi was waiting outside the store, he noticed Mei and Naoki walking with a strange stick covered with cloth.

Kouichi: Umm, what is it?

Mei: I bought a new easel.

Kouichi: Definitely? It seems quite strange to me.

Mei: It's not an easel, but you'll see later

Kouichi: It's something dangerous, right?

Naoki: Arisaka Type 38, we also have ammunition.

Kouichi: Naoki, your father fully deserved to die, but I wish I didn't have to clean up his body or anything like that...

Naoki: Then you will help us clean this Arisaka.

Kouichi: Does it even shoot?

Mei: Yes, I shot it myself. It works, but it freezes.
It is also not that rusty, it was kept in quite good conditions.

Mei, Naoki and Kouichi started cleaning their weapons.

After an hour she was relatively fit to shoot, Mei left the light on in Kirika's studio, they were waiting for Shion.
But Shion didn't come, the whole night passed. Nobody even fell asleep.

That same night, there was a knock on the door of Akinobu Yotoi's house.
Akinobu: Excuse me, but what do you want in the middle of the night?

Shion: Yotoi-kun, don't you recognize me?

Akinobu: I don't know who the hell you are or why you're bothering me at 2 a.m.

Shion: I'm glad that your school friend from 27 years ago, Yatagai, is on the right track in life... I came to check on you.

Akinobu: How the hell do you know who I was hanging out with when I was 15?

Shion: Because you were members of my yakuza, don't you remember?

Akinobu: Wait, are you... Shion Muneyoshi?

Shion: Correct, I am Shion Muneyoshi.

Yotoi was terrified and froze in place, but he didn't have time to save himself. Shion quickly shot him.
There were many killings during the week, mostly people who knew Shion.

Akinobu Yokoi, 42 years old.

Yoshiki Yatagai, 41 years old.

Nozomi Yatagai, 43 years old.

Rumi Yatagai, 12 years old.

Yasuharu Kiyohashi, 48 years old.

Yuho Kimura, 44 years old.

Junko Kimura, 14 years old.

It was a list of people Shion had killed, most of them had contact with Shion in his youth or were members of their families.
The press became interested in the case, Shion was nicknamed "The Vampire of Yomiyama" Despite so many murders, he still remained elusive, he even managed to escape from manhunts, and over time he disappeared, again like 13 years ago. However, murders continued throughout February.
