*BOOOOM!*
A loud sound of "boom" was heard from a distance, causing Fiore to set up a barrier in Bucharest to feel startled and frowned.
When Fiore turned her head, a gust of wind and sand scattered, along with the fluctuation of Magic Power which made her knew instantly what was happening.
"Has the battle begun?!"
Fiore manipulated her wheelchair and rushed over in the direction of the source of that loud "boom" sound, however, Chiron stopped her!
"Master, please stop! That place is dangerous!"
Chiron held his bow and arrow, appeared in front of her with a very serious expression, telling her what was happening.
"It's not the Assassin of Black that has appeared, but Berserker of Red."
Chiron, who owned clairvoyance skills, immediately saw the situation instantly.
"Berserker of Red?!"
Fiore was taken aback.
Did the Berserker of Red appear in Bucharest?
Fiore frowned and said, "Is this Red Faction's trap? Has the Assassin of Black fallen in the hand of their faction?"
Regarding Fiore's question, Chiron gave his own guess.
"There is no way to determine this situation at this moment whether it is being done by Red Faction or not." Chiron looked at Fiore and said, "However, besides the Berserker of Red, there seem to be one or two servants from the Red Faction. Master, we have to be careful now."
Fiore's eyes began to change and she became worried about him. She tried to calm herself and then made up her decision.
"First, we have to support Kasugano-kun first."
There was anxiety on Fiore's face when she thought he would be attacked by the servant from Red Faction. "The Berserker of Red should be fighting against our Berserker of Black so Kasugano-kun should be alone at this moment. In the face of the Assassin of Black's attack, if we don't go and support him, I am afraid that he's going...." She knew that she needed to save Haru since she knew if he lost so soon then the Black Faction would be a disadvantage over Red Faction.
Chiron also agreed with Fiore's decision.
"I just looked around the city and there seems to be a strange mist on the east. That mist is obviously abnormal and it should be related to a servant."
Fiore nodded and understood Chiron what Chiron wanted to express.
In other words, Haru should be in that mist!
"Let's go quickly, Chiron!"
Chiron nodded.
Then the two of them quickly moved toward the east to save Haru as soon as possible.
---
Haru frowned when he saw the white mist which had surrounded him. Even though the mist had surrounded him, it didn't mean the mist was touching his body since he was using his gravity magic to push all the mist away from him, even though, he knew that he should be alright from the mist.
However, it was better to be careful.
Haru knew that this mist was the Assassin of Black or Jack the Ripper's Noble Phantasm.
The Mist.
This mist wasn't a normal mist, but it was mixed with sulfuric acid which was made with magic.
The mist, wrought with magical energy, forms a bound field around an area over a dozen meters that has a negative effect on all those who enter within the perimeter, even though it can be a means of keeping people out.
Normal humans will quickly faint from pain upon coming in contact with the dense cloud of enveloping smoke as simply breathing it in burns their throat and direct contact with their eyes causes them to fester. They start to suffocate due to being unable to breathe, and they cannot see anything as they writhe in pain.
Jack the Ripper can easily use this time to selectively kill them, or she can simply wait for them to be inflicted with death within a few turns.
Magus will not immediately perish, but they will receive continuous damage and makes it difficult for them to use Magecraft if they do not take countermeasures.
Heroic Spirits will not receive damage, but they will have a Rank Down in Agility
However, such a Noble Phantasm was useless to him, showing how cheating and powerful he was.
"Huh?"
A somewhat innocent and surprising voice rang from the surroundings.
"You don't get eaten by the Mist?"
Along with such words, the surrounding mist became dense and it started to twist as if trying to eat Haru alive.
However, Haru took out his knife from his zipper storage and swept it down toward the knives which were thrown toward him.
*Clang!*
As if Haru used his magic, the knives which were thrown toward him suddenly turned and returned toward its master with double speed.
*Swoosh!*
However, those knives hit nothing and only passed through the mist.
"Wow!"
The innocent voice came out from the surrounding mist once again.
"I'm quite good at it, right?" Haru said with a smile.
The innocent voice chuckled and said, "Big Brother, you're very funny."
"Is that so? So can I meet you now? From your voice, I can tell that you're quite a cute little girl," Haru said.
Then the mist slowly dissipated, and a petite figure slowly appeared.
This petite figure was a young girl, and she was about 12 or 13 years old.
She had lavender-colored hair with green-yellow eyes, with stitched-up scars on her face. Her upper body was that of an adolescent, while her lower body was more mature like that of an adult, creating an odd juxtaposition to her appearance.
She wears a tattered coat as a cloak over her outfit, and at the small of her back, she carries a number of sheaths that hold her knives.
At this moment, the young girl looked at Haru with a surprised expression.
"Even though you're only a master, you're very strong, Big Brother! You are not eaten by the mist and you can even return back my knives, who are you Big Brother?"
"Call me Onii-chan, then I will answer your question," Haru said.
"Onii-chan?" She titled her head with a confused expression.
"....."
Even though this young girl was a psychopath, he had to admit that she was quite cute.
If someone heard her voice, no one would ever think that this young girl was the legendary Jack the Ripper.
'If this young girl is 10 years older....'
Haru quickly shook his head and asked, "Do you want to know my identity?"
"Yes, Onii-chan."
"Do you really want to know?"
"Yes, tell us Onii-chan!"
She wasn't sure, but she was really curious about him since his aura made her relax somehow.
"Well, my name is...."
"Is...?"
"Secret."
"..."
Jack was stunned but then pouted. We hate someone who teases me, Onii-chan."
"Well, what are you going to do now?"
"We're going to kill you!"
The mist then became dense once again and this time, it was thicker than before and Jack disappeared along with the mist.
Assassin of Black.
The real name of this servant was Jack the Ripper.
Jack the Ripper was a killer who had killed at least five people in two months from August 31, 1888.
All of those killed were women.
Not only that, the organs of those women who were killed were sent to the newspaper, and signed letters were added on the parcel, announcing the existence of such a cruel killer to the world.
Perhaps compared to other non-hero servants in Holy Grail, the crime of Jack the Ripper was relatively small since she had only killed five women.
However, the case that was committed by Jack the Ripper was an unsolved case without any conclusive evidence except the dead body.
In addition, no one can determine the race and gender of Jack the Ripper so the identity of this killer is shrouded in many mysteries and the killer has become a figure that no one knows.
Thus, Jack the Ripper became a modern Heroic Spirit.
Its story was different from many heroes with a long history, but its existence was similar to a legendary monster, demon, devil, wraith, or ghost.
Such an existence appeared in front of Haru, but still, he had to admit that Jack the Ripper was quite a strong opponent, especially with the combination of "The Mist" and "Presence Concealment rank A+".
Even if it was a servant, it was impossible to detect the existence of Jack the Ripper, showing how strong she was as an Assassin.
"Isn't it a bit too cruel to kill me just because I tease you, Jack-chan?" Haru asked.
"....."
"Onii-chan, do you know our real name?"
Jack was surprised when Haru knew her real name, but when she asked that question, her voice sounded on the surrounding mist which made it impossible to determine her location.
"Well, you're very famous after all, but I don't expect that the legendary killer is a cute girl like you," Haru said.
Jack chuckled happily and said, "We're happy that you've praised us, Onii-chan, but you still have to die." Leaving such words, she completely merged into the mist.
Haru let out a long sigh and shook his head. He raised his knife and said, "Well, if that's your answer, then blame me for killing you first, alright?"
