Hirota wandered around Yomiyama with Asuka,
He couldn't remember anything from his life as Naoki Muneyoshi.

Hirota didn't feel falseness, and neither did Ikuyo and Shuuhei, his adoptive parents.

In March 1999, after Mei killed Shion, Kaito drove Naoki to the Hiiragi estate.

On place were Kiyoshi Hiiragi, and his son Shuuhei Hiiragi,
Shuuhei lived with his wife Ikuyo in Okinawa, although Shuuhei was born and raised in Yomiyama, and Ikuyo were from Fukuoka.

Hirota Hiiragi existed, howewer he died riding a motorcycle a few months ago.
Shuuhei and Ikuyo's only son, both Shuuhei and Ikuyo were depressed by his death.
Unlike Yukiyo Misaki, Ikuyo Hiiragi did not intend to adopt Hirota's replacement.

Hirota Hiiragi was of a similar age and appearance to Naoki.
Hirota had fairer hair than Naoki, and blue eyes instead of green.

Apart from these minor changes, Naoki looked almost like Hirota's doppelganger, but Hirota's attitude towards the world.

Kaito entered the Hiiragi mansion abruptly.

Kiyoshi: Kaito-sama!, what happened to Naoki-sama?!

Ikuyo: Oh my god..

Shuuhei: Someone call a doctor!

Kaito: Shuuhei-san, I'm a doctor.
I could you do me a favor, Shuuhei?

Shuuhei: What's the matter?

Kaito: Please adopt Naoki, let him live under another identity, away from Yomiyama...

Shuuhei: What exactly happened to him?

Why doesn't he have a right arm?

Kiyoshi: This young man had just killed his father – ''The Yomiyama Vampire''.

Kaito: I'm so ashamed of my brother, please let Naoki at least have a chance to live without this stigma...

Shuuhei: I would very much like to adopt Naoki, however, my wife will not allow me to do so.

Ikuyo: It's not like that, but I don't want him to live under the identity of our recently passed away son – Hirota.
Despite the fact that it is very similar to him.

Shuuhei: So, how about Naoki joining our family as someone else?

Ikuyo: Yes, but I will never recognize him as a son, nothing can replace Hirota.

Kaito: I really thank you for this Shuuhei, Ikuyo.

Do you happen to have disinfectants and a first aid kit?

Sachio: There should be something.

Kaito bandaged Naoki's amputated arm to completion.

No infection occurred, and Naoki awoke after an hour.

Naoki: Kaito, where am I?

Kaito: This is the last day we see each other for the next few years...

Naoki: What?

Kaito: I had to amputate your arm.

Next to Shion's corpse, your arm is still lying somewhere.

You must disappear for now.

Naoki: Shion's corpse? Did you kill him?

Kaito: No, but I saved your friend's life.

Naoki: So Mei killed him?

Kaito: If I hadn't cut off a few of Shion's fingers with an axe she wouldn't have been so lucky.
This was the first time I have caused injury to anyone.

Naoki: You eat meat Kaito, right?

Kaito: Animal life, no matter how we wish it would never be equal to human life, so this is a bad argument Naoki...

Naoki: No matter what, I am grateful to you for being able to live with you for these five years.

And also thank you for saving Mei.

Kaito: I am your uncle, so it was my duty to adopt you then, I am also a doctor, my duty is to protect human life, even if it meant contributing to take away someone's life.
Yes, these were my responsibilities, however, know that you are like a son to me, Naoki. And you always will be.

Naoki and Kaito hugged for the first time, Naoki had never felt the love of a parent for his child, even though Kaito was his uncle, all the time Naoki saw him as a fatherly figure.
Even during his time in Okinawa.

On the first day of his new life, he used his skill on Shuuhei and Ikuyo.

From then on, they thought Naoki was Hirota, and he didn't die in an accident a few months ago at all.
For six years, Naoki owned his memories, and lived artificially as Hirota Hiiragi, until he once returned to Yomiyama.

Shuuhei and Ikuyo forgot their promise to avoid that city, however Kiyoshi Hiiragi died.
At his funeral, Naoki used his ability to the maximum.
The tremendous pain in the right eye was unbearable, in addition to hemorrhaging, the eye began to pus.
Although Naoki used his skill on many people at once during Kiyoshi's funeral ceremony, he had to use it again - on himself.

Some of the Hiiragi family, despite being influenced by Naoki, did not believe Hirota had survived the accident.

As a result, Naoki used his skill one last time - on himself.
The condition of his right eye was frightening, Naoki, in addition to clearing his memories, ordered himself to pluck out his right eye.

He erased his memories as Naoki Muneyoshi, and filled them with false memories that belonged to the real Hirota.
From 1999, Naoki never saw Mei again until 2007.

Mei finally agreed to a relationship with Kouichi when the two were in college.

Mei became unexpectedly pregnant, which caused Kouichi and Mei to marry sooner.

They wanted to provide their child with a normal family.
Despite the difficulties, Kouichi and Mei graduated from their college.

Their wedding, which took place in 2006, was held in Yomiyama.

After the wedding, Kouichi's father was pressed by Ayane and Ai for 30,000 yen after losing a chess game.

Hirota entered the alley where he first met Ayato many years ago.

Asuka: Hirota, Hirota, hello.

Hirota stood as if he had been caught off guard, feeling a strange sensation, like déjà vu

Hirota: Oh, sorry I got lost in my thoughts.
Since Hirota returned to Yomiyama, he has felt stranger and stranger every day.
old memories were not coming back, but Hirota felt a sentiment he could not rationally explain to himself.
Meanwhile, Kento asked his brother Kouji to contact Kaori Hasegawa, one fully functional survivor from Class 3-3 of 2004.
Kento was aware that Hasegawa probably did not remember the death of an extra of their class.
However, to resolve the uncertainty he has decided to take such a step.
Kaori was reluctant, but ultimately agreed.
Kento started asking her questions about class 3-3 from 2004-2005

Kaori didn't know much, however, after a few minutes of conversation, Kento got to the point.

Kento: I know that you most likely do not remember the death of this person, but do you associate Hirota Hiiragi?

He could have been anyone associated with class 3-3 ,2 years ago

Kaori: I'm not sure, but something comes to mind about the name.

Kento: Do you remember if it was a man or a woman?

Kaori: I don't know, I only associate the name.

It is possible that someone with this name was my classmate.

Kento: And could this person have been connected to this class in any other way?

Supposedly in 1998 the 3-3 class had an assistant educator, was there a possibility of a similar or identical position in 2004/2005?

Kaori: Not likely, although I don't remember.

Kento: It could have been the most trivial function, give, for example, a separate janitor for the class 3-3.

Kaori: No, there was certainly no such post, although I don't know.

The Class 3-3 calamity of 2004 was the most severe in the entire history of the class,
For the first six months, 2-3 students or family members per month died.

However, the situation worsened in October, when 3 countermeasures officers were murdered.

From then on, chaos reigned in the classroom, one of the students - Emi Aihara went crazy, she was going to survive the curse together with her boyfriend - Atsumi Takeshita.
Emi deliberately killed other students, or contributed to their deaths.

Initially, she did so covertly; however, in March 2005, she committed a triple homicide, after Atsumi's death.
Emi killed 20 people, mostly pushing them down stairs or off the roof or in front of vehicles.

She also killed directly - with a knife.
Before Atsumi's death, she also killed an additional person, however, Atsumi died in an accident and yes, it was not the curse's fault, but an unfortunate accident.

Because of this, she lost the last shreds of her sanity
She also tried to kill Kaori Hasegawa and Dr. Kaito Muneyoshi.

Kaori, however, had been practicing martial arts since childhood, and it saved her, and the doctor's lives.

Kento: Hasegawa-senpai, so could the extra in 2007 be Hirota Hiiragi?, he is now a post-graduate, so he could have been a teacher or someone else for the 3-3 class in 2004/5.

Kaori: I have no idea, I associate the name, I think someone like that was in my class, however, I don't know why he would be so old.

Kento: Maybe Hirota dropped out of school, and was going to at least finish middle school.

Well although Hiiragi is a rather rich family, there could have been a wasted son.

Kaori: Maybe because of the curse, I don't remember anything about him, I only associated his name.

Kento: It seems to me that this is enough, thank you kindly for the interview.

Kaori: Initially, I did not want to return to this class because of calamity of 2005, however, if in this way I can prevent another one.
