Comprehensive Manga: The Master is not here today.

Back to the point.

The current chairman of [Yagiri Pharmaceutical] is named Yagiri Namie, the niece of the former chairman Yagiri Seitaro.

The other party is currently only 25 years old and is said to be a strong woman with strong working ability. She is expected to "lead the company back to its peak."

The head that was originally kept by the former chairman also fell into the hands of Yagiri Hae.

Although the other party also owns real estate, he lives directly in the company most of the time. If nothing unexpected happens, the head should be kept strictly in the company by the other party.

In short, everything is ready, and the next step is to really take action.

The time finally came to midnight, and Ritsuka Fujimaru and others arrived at the agreed meeting place - the rooftop of an apartment building diagonally opposite the Yagiri Pharmaceutical company building.

Haibara Ai stayed at home to provide remote support, waiting for instructions from Fujimaru Ritsuka, ready to hack into the surveillance system within the other company at any time.

Not long after Fujimaru Ritsuka and others arrived, a slight strange noise suddenly came from the side of the apartment building. It was Celti driving a motorcycle, speeding up the wall, and successfully reached the roof to meet up with everyone.

She was accompanied by Kishitani Silla, who was sitting in the back row.

'Sorry to have kept you waiting.'

Celti glanced at Kishitani Silla behind him and said a little embarrassedly:

"I didn't intend to bring him here, but..."

The intruders who carried out the plan were professionals sent by Ritsuka Fujimaru, while the rest of them were only responsible for supporting them outside.

However, in the worst-case scenario she anticipated - that is, if the infiltration failed, they might have a direct conflict with the other party.

If that really happens, Kishitani Silla will obviously be a burden that holds the team back.

However, the other party followed her forcefully, saying, "What if Celty gets the head and runs away?" She could do nothing about it.

Fujimaru Ritsuka expressed his understanding and said with a smile:

"Don't worry, at least we are absolutely safe here."

On the other side, Kishitani Silla also came up and smiled helplessly:

"Excuse me, I was originally planning to ask a friend who is an information dealer for detailed information about Yagiri Pharmaceuticals."

"As a result, I just found out that the other party seemed to have been struck by lightning, so I didn't find out anything."

"Eh?"

Intelligence is secondary. Upon hearing this, Fujimaru Ritsuka was a little surprised and said:

"Struck by lightning? Is the other person okay?"

"what,"

Kishitani Silla shrugged indifferently and said:

"Unfortunately, the other party is very lucky and does not seem to be in danger of death. He is just still in a coma."

"?"

Didn't he say he was a friend? Why did he sound like he wished the other person would die?

"I heard it was struck by lightning the night before yesterday."

"It hasn't rained in the past few days, but this happened."

Celty couldn't help but sigh:

"I wonder if I should say that Izaya is unlucky or that he finally got his comeuppance?"

“I think it’s probably more of the latter.”

Listening to the conversation between the two, Fujimaru Ritsuka roughly understood that the guy who was struck by lightning did not seem to be a good person and was not very popular.

The gossip and small talk soon ended and everyone returned to the main topic. Then Celti and Kishitani Silla looked at the stranger they noticed at the beginning, Kato Danzo, who was dressed as a ninja.

This person should be the professional that Fujimaru Ritsuka mentioned.

Judging from the way he's dressed, could he be a real ninja?

The two parties nodded to each other and briefly got to know each other. Fujimaru Ritsuka looked at the time and said with a smile:

"Well, it's almost time to start taking action."

She called Huiyuan Ai, and after confirming that the internal surveillance system of Yagiri Pharmaceuticals had been hacked, she nodded to Kato Danzo and said:

"The rest is up to you."

"Yes! Received the order, Danzo begins the action!"

Kato Danzo nodded solemnly, then turned around and jumped down from the roof.

"?!"

Celti and Kishitani Silla were startled, but when they reached the edge of the roof and looked down, they found that the other party had disappeared without a trace and they didn't know where they had gone.

Worthy of being a ninja.

During the time when the other party was taking action, they had nothing to do except to be alert to the surrounding situation, so the atmosphere became a little quieter.

"that……"

At this time, Kishitani Silla suddenly spoke up and said to Fujimaru Ritsuka:

"I heard from Celty that you guys seem to be investigating the Ikebukuro Slasher incident, right?"

"That's right..."

Fujimaru Ritsuka nodded, and seeing that the other party took the initiative to bring up this matter, he asked curiously:

“Could it be that Mr. Silla knows something?”

"Well, almost."

Kishitani Silla pushed his glasses and said with a smile:

"To be precise, I don't know the true identity of the Ikebukuro Slasher, but after looking up some related rumors online, I can roughly confirm one thing—"

"That Ikebukuro slasher should be the owner of the demon sword [Sin Song]."

"Demon Sword [Sin Song]?"

[Sin Song] is a demon sword that once existed in the Shinjuku area. Just like the famous demon sword Muramasa, it is a sword with strange magical powers.

It is said that [Sin Song] has its own consciousness and can devour people's hearts, control humans, and even spread and reproduce like a virus. Anyone who is injured by [Sin Song] will become the object of control by the holder of [Sin Song].

Not only that, [Sin Song] seems to have the ability to sever souls.

"…As for the holder of Sin Song, the most obvious feature is that when using Sin Song, their eyes will emit a scarlet light."

After listening to Kishitani Shinra's story, the atmosphere suddenly became quiet. Fujimaru Ritsuka thought about this information with a thoughtful expression.

"The Demon Sword [Sin Song]!?"

"Wait a moment!"

Then, Celti asked in surprise:

'Silla, how do you know these things? Why have I never heard of them? ! '

"Well..."

Kishitani Silla scratched his head and laughed:

"My father seems to have once been the owner of Sin Song. I have read some of his notes before, and he seems to have conducted some research on Sin Song."

"But after finishing his research, he sold [Song of Sin]."

"Stern? Tsk, so it's that guy?"

Hearing Kishitani Silla mention his father, Celti couldn't help but let out a "tsk" sound, his tone sounding quite disgusted, and it seemed that he didn't have a very good relationship with the other party.

Fujimaru Ritsuka asked curiously:

"May I ask who your father is?"

"Don't worry too much about him, he's just a freak who likes to study all kinds of weird things."

Kishitani Silla smiled indifferently:

"But speaking of which, Celti was also invited to our house by him."

'Well, forget about that spoilsport.'

Celti expressed his disgust for Kishitani Silla's father without disguising himself, and took the initiative to change the subject:

"By the way, Ritsuka, speaking of [Sin Song], I actually have some information here."

"Eh? Really?"

Ritsuka Fujimaru opened her eyes wide. New information appeared one after another, making her feel a little overwhelmed.

Celty took out his PDA and started to operate it. He quickly opened a chat room and showed her the content.

In the chat room, there happened to be a user named [Sin Song].
