Naoki told Mizuki about the situation in this timeline, after returning home he continued to behave strangely but in a more normal way.
However, he still seemed strange to everyone.
Mizuki's stay in this timeline lasted 3 days or 16 hours in the original world.

Mizuki played baseball with his 11-year-old cousin, Shinya Muneyoshi.

Shinya batted the ball away and hit Mizuki right in the head.

Mizuki found himself in total solitude, just like his mother he saw the color of death while in this abyss, he did not know what was happening until he awoke from his coma.

Mizuki told his mother about all this.

However, he did not remember exactly what happened during his time there.

Mei: I used to have that too, I was probably not much older than you at the time.

Take it easy for now.

Mizuki: Is it known what happened to the rest?

Mamoru and Tohru Ogata and Nao Sekine?

Kouichi: I think Mamoru Ogata was arrested on suspicion of murdering you and his brother.

Mizuki: No, Mamoru didn't do it, neither did Tohru...

I think Sekine-san must have done it.

Mizuki got a headache.

Mei: I think you should rest more.

Mizuki, after feeling better, made a statement to the police that Tohru Ogata was killed by Nao Sekine.

Policeman: This is a difficult case, however, Mamoru Ogata's fingerprints were found on the hammer, and he is suspected of attempting to kill you as well as the suspect's brother.

Mizuki: From what I remember I saw Tohru and Mamoru Ogata before the nail was driven into my head.

So it is impossible that Mamoru Ogata did it.

Policeman: Ryuutarou Ogata declared that in addition to your corpse as well as Tohru Ogata's, he had only seen Mamoru Ogata.

This is really a strange thing, ehh.

Can you ask for a description of Nao Sekine?
Dark long hair, green eyes, about 160cm tall.

Mamoru Ogata was exonerated after Yomiyama North librarian Hajime Ueda confirmed that Nao Sekine was the dead person of the year.

This was in April 2023.

Naomi's feelings for Tohru grew stronger by the day, Naomi wanting to support Tohru said that she was the second person to return,

Misaki, on the other hand, was called by Chitose.

Misaki arrived at her mansion, it was another contract, however this time the target was an old businessman, and his wife.

Chitose: Their home and also business is located in Misakicho, heh Misakicho you think this is just a coincidence?

4-4 Misakicho, this is the exact address, if you execute this Michika escort you will no longer need it.

I will trust you enough to execute your own contracts from now on.

Misaki was shocked, the address seemed familiar to her, however she was afraid to refuse Chitose.

Misaki: Of course, Chitose-sama.

Chitose: I would like you to execute this contract in five days evenly.

I guess you don't mind it Sakakibara-san?
You know, I could give you another contract, an easier one, but I would very much like this businessman to die, his wife is usually at home, moreover, she still runs the store despite her age.

So how will it be?

Misaki tried to hide her uncertainty, the address sounded familiar, she even seemed to have been there once, or heard it at home.

Misaki: Of course Chitose-sama.

Chitose: Good, I'm glad.
I hope that you will prove your loyalty to me.

On her way out of the Minamiyashiki mansion, Misaki met Naohisa Minamiyashiki.

Naohisa: Umm pardon? This is the second time I've seen you in my house, do you have any business with my family?

Misaki: Uhh, yes.

Misaki tried to ignore Naohisa and went quickly thoughtfully in her own direction.

After a few minutes, Naohisa ran up and saved her again from a car accident.

Naohisa: H-hey, Y-you sh-should pay attention to the r-road…

Naohisa ground these words, it looked like he had broken his rib saving Misaki.

Misaki: You know, you didn't have to throw yourself.

Misaki administered first aid to Naohisa and called an ambulance.

Naohisa: Thank y-you…

Misaki: I'm returning the favor.

Naohisa: It's just a b-broken rib...

Misaki: Whatever you think, I'm going to go.

Naohisa: Wait...

Misaki: What?

Naohisa: You should wait until the ambulance arrives...

Misaki: Why?

Naohisa: Maybe you got hurt too.

Misaki: No, I don't think so.
But I'm going to stay with you now.

Naohisa: Thanks..

Misaki: What is it like at the École d'Yomiyama?

Naohisa: Tuition fees are huge, unless you are a genius, then they are much smaller.

Only the top 5 students who apply to this high school have cheaper tuition, however, they must maintain high grades, otherwise the tuition rates return to their former level.

Misaki: Is it a large school?

Naohisa: Quite small, however, this school does not focus on local youth, most students are from outside Yomiyama.

Misaki: Are you doing well in this school?

Naohisa: It is tough, even very tough, however, somehow I manage.

In fact, my mother kind of forced me to attend this school.
She will probably also try to force my brother.
But he wouldn't have made it at École d'Yomiyama

Misaki: You have a brother?

Naohisa: Yes, how about you, do you have any siblings.

Misaki: I have a brother and a twin sister, if that interests you so much.

Naohisa: I thought at first that you were a mean person, but you actually show that you are nice.

You just don't like to demonstrate it.

Misaki turned her head away and blushed.

Misaki: Maybe..

An ambulance arrived taking Naohisa to the hospital.

In addition to a broken rib, he also had a bruised bone.

However, from that point on he began to make contact with Misaki.

The next day at school, Miyuki Asahina resigned from her position as Countermeasures' deputy; she claimed, like the rest of the class, that Shion Urushibara would be more useful to Countermeasures than her.

Ken: Urushibara-san, welcome aboard...

Saki: We hope to stop the curse this year, we hope these ricin poisonings were not related to the curse.

However, not everyone in the 3-3 class was charmed by Shion.

Ayumi Teshigawara, Akira Nanami, Kana Ishigami and Yuuichi Kasuga objected to Shion's promotion so quickly to the Countermeasures

Ayumi: I have a question Urushibara-san.

Shion: Yes?

Ayumi: Are you even from Yomiyama? Do you know about the situation of our class? Are you even concious of what are you into?

Shion: Definetly, although I don't remember my early childhood, since I was adopted by Mr. and Mrs. Akazawa I quickly became accustomed to the city.

I'm also familiar with the story about the 3-3 class, as well as that whole urban legend about Misaki.

I also know a lot about the Great Clans of Yomiyama much more than you all can know.

Yuuichi: In my opinion, you should not be promoted to Yagami-kun's deputy, you only recently joined this class, almost no one knows you.

Shion: Yuuichi Kasuga-kun huh?
Born May 2, 2010 in Yomiyama, you have an older sister - Rumi, you live in Seitenchou...

Yuuichi became afraid, began to back away and Shion began to take steps forward, thus showing her dominance over him, and imposing obedience on him.

Shion: Your father is a clerk, your mother is a bank employee, should I go on and on?

Yuuichi: Please forgive me... Urushibara-san.

Ayumi couldn't stand it, she walked up to Shion and pushed her.

Ayumi: Who the hell are you!
You may be from Yomiyama, however, you are definitely not human!

Since we recognize your existence, and deaths have begun.

Then answer me one question, Why did Ogata-kun insinuate talking to you all the time?

This is not normal isn't it?

Tohru-kun is unfortunately not in his right mind, however, since you appeared he stopped talking to you.

So did Sakakibara-san.

They have forgotten about you.

Shion, in response, approached Ken Yagami and whispered something to him about Ayumi Teshigawara breaking the rule.
Ayumi was declared non-existent for mentioning Tohru Ogata and Naomi Sakakibara, this was to have lamentable consequences, later that same day.

Ken and Shion talked to each other after the lesson, Ken and Saki were impressed by Shion's skills and knowledge.

It was supposed to rain that day, so Shion had an umbrella with her, Ayumi was hostile to her so she decided to follow her from a distance.

Just as Shion and Ken were about to say goodbye and go home, Shion put the umbrella to Ken's calf and clicked the button on the umbrella,

She apologized to Ken for "unintentionally" touching his calf with the umbrella and went home.

This was all happening in front of Ayumi's eyes, everything looked similar to the assassination attempt on Georgie Markov.

This was soon to prove true.

Although Ayumi notified the police of the attempted ricin poisoning, it was not possible to save Ken Yagami.

He died, as did Rika Honma and Sakayori.

The day after Ayumi Teshigawara's testimony, police searched the Akazawa family's home.

Shion herself was taken in for questioning on the matter.

She was questioned by a new police officer, Masashi Nomura, who was privately related to Chigusa Nomura, a retired detective.

Chigusa Nomura was his grandfather's younger sister, and although Chigusa had no children, she treated Masashi at the end of her life almost as her own grandchild.

Chigusa was ill with lung cancer, and as a result had little time left.

As a result, Masashi was to inherit her house, so he moved to Yomiyama.

At the hearing, Shion behaved differently from the average person her age in a similar situation, and this surprised Masashi somewhat.
