Comprehensive Manga: The Master is not here today.

Taking into account the situation on Anri Sonohara's side, they finally set the time of action at 9 o'clock in the evening, and the gathering place was at Ikebukuro West Exit Park.

So, Kida Masaomi, Kadota Kyohei and others who were waiting on the roadside finally saw Fujimaru Ritsuka and Sonohara Anri reappear in their sight.

Both of them had smiles on their faces and seemed to be getting along very well.

"Anri-chan!"

"Anri-san!"

Seeing the worried and questioning looks of her two companions, Sonohara Anri nodded to them to reassure them, then turned around and bowed slightly to Fujimaru Ritsuka and said:

"Then Ms. Ritsuka, I will leave first."

"Well, walk slowly."

Fujimaru Ritsuka waved goodbye to the other party, looked at the backs of the three people leaving, and turned to Kadada Kyohei to thank him:

"Mr. Kadota, thank you for your help as well."

If it weren't for the fact that Kadota Kyohei and the others knew the young man named Kida Masaomi, they would probably have to spend a lot of time explaining if they wanted to talk to Sonohara Anri alone, right?

"You're welcome, and we didn't do anything."

Kadota Kyohei smiled indifferently and then asked:

"So how's the situation, about the man-slashing demon?"

Fujimaru Ritsuka smiled and said:

"Thanks to the intelligence they provided, we have made great progress. The Ikebukuro Slasher incident may be resolved soon."

"is it?"

Although there were many things that concerned him, he also understood that there were some things that he didn't need to ask, and shouldn't ask, so he just smiled and said:

"That's good. In this case, it's worth waiting a little longer."

Then, the other party kindly offered to take them back, but Fujimaru Ritsuka declined with a smile. After all, he couldn't keep bothering others like this.

Before parting, she also gave Kadota Kyohei and the others a business card and said with a smile:

"If you accidentally encounter any troublesome problems, you can try to come to us."

……

"Chaldea Mysterious Office..."

"How cool~!!"

Yumazaki Walker shouted excitedly:

"A mysterious agency... and a mysterious beautiful girl who handles all kinds of supernatural events... Didn't expect it to unfold like this?!"

At the same time, Karizawa Eri seemed to have thought of something and said excitedly:

"If that's the case, could it be that... that slasher is actually a runaway psychic? Or a creature from the dark world? Or even an alien?!"

"In the peaceful daily life, the truth of the world is suddenly revealed——?!"

"What a mess..."

Kyohei Kado rubbed his temple and looked at the business card in his hand, his mind full of questions.

So, who are those girls?

but……

He stared at the business card for a while, thought about it carefully, and then carefully put it into his pocket.

……

...

On the way home, Celti suddenly called Fujimaru Ritsuka and said that they had found a clue.

Selti said:

"Mori Yan said that he later sold the "Sin Song" as an antique to the owner of an antique shop called "Sonoharado" in Tokyo."

"I'll send you the address later, but I don't know if this store is still in business."

"Yeah, that's okay. That's enough, thank you."

After hanging up the phone, Fujimaru Ritsuka and Mashu couldn't help but look at each other.

First of all, if nothing unexpected happens, [Sonohara-do] should be the antique shop opened by Anri Sonohara's family, right?

In other words, there is another clue pointing to Anri Sonohara, but this is only a disguised explanation of why she possesses [Sin Song] and is not of much use in the current situation.

In addition, Fujimaru Ritsuka said with a frown:

“I actually sold the demon sword as an antique to others casually... I always feel that Mr. Silla’s father is the one who should be interviewed in particular...”

Matthew added:

"Also, it seems that Miss Celty's head was stolen by the other party and then sold, right?"

——Interview! Must interview!

Of course, we have to wait until the other party comes back.

Back to the point.

It's not just Celti. After Ritsuka Fujimaru and the others returned home, Haibara Ai also brought them the latest developments.

"I tracked down this user named [Sin Song] and found that the addresses of the strange posts on the forum recently all came from the same phone, which means they were made by the same person."

While showing the information on the computer, Huiyuan Ai explained:

"So I hacked into the other person's phone and quickly found her identity information."

The user named [Zuige] who made the post online was originally a female student at Raira Academy, but she was not Anri Sonohara, but a girl named Haruna Shikagawa.

Haruna Shikagawa was originally a freshman at Raira Academy, but her information showed that she had been expelled a year ago.

The rumors about the "Ikebukuro Slasher" also began to spread gradually during this period!

"Thank you for your hard work, Ai. You've been a great help."

Fujimaru Ritsuka smiled and rubbed Haibara Ai's hair. Haibara Ai also slightly curled the corners of her mouth, showing an expression of enjoyment.

"Nothing, as long as I can help Sister Ritsuka."

After praising Haibara Ai, Fujimaru Ritsuka looked at the other party's information and fell into deep thought.

Mashu said to Fujimaru Ritsuka:

"Senior, compared to Miss Anri, I think this person seems to be more suspicious."

"Ah."

Fujimaru Ritsuka nodded in affirmation and continued:

"But there are still some questions. I guess we can only confirm them after we meet each other, right?"

What still confuses them is that if this Haruna Shikagawa is the man-slaying demon - that is, the [Child of Sin Song] - then who turned her into the [Child of Sin Song]?

Is that Anri Sonohara?

Or another [Son of Sin]?

Or rather, are they the previous owners of "Sin Song" before Anri Sonohara, including Kishitani Silla's father, Kishitani Moritasu?

Or was it something else that they had not anticipated at all?

Of course, no matter what, after Anri Sonohara gathers the "Children of Sin Song" tonight, the truth will gradually be revealed, right?

At the same time, in order to completely eliminate the "Children of Sin Song" tonight, Fujimaru Ritsuka still has to make some preparations.

"call--"

The light of the Command Seal flickered, and the summoning array formed by the condensed magic power stirred up waves of magical storms. Then, a girl who was like a cold flower appeared in front of them -

The other person had neat short hair, and his plain black eyes revealed a cat-like laziness. He was wearing a blue kimono with a red leather jacket on the outside.

Although the combination is weird, it looks surprisingly harmonious when worn on the other person.

The most important thing is that the opponent has the same appearance as Ryougi Shiki who appeared in the Jujutsu Kaisen world.

She is Ryougi Shiki, but not [Ryougi Shiki].

Looking at the other party, Fujimaru Ritsuka smiled and greeted:

"I'm sorry to bother you this time, Sister Shiki!"

"Miss Shiki, thank you for your help!"

"It's my turn now..."

Ryougi Shiki first looked around casually, then said:

"So, what is the goal this time?"

"It's the offspring of a demon sword, um..."

Fujimaru Ritsuka thought about it and said with a smile:

"To put it simply, it is some unclean things hidden in the human body, which are easy to identify."

"When the time comes, all you need to do is kill them all, Sister Shiki."
