Supervisory officer.
This is Karen Aldessia's current position.
The full name is the Holy Grail War Supervisor of the Templar Church in Fuyuki City, Japan.
The Holy Church is very persistent in the management of "holy relics" and has established the "Eighth Mystery Society" for this purpose. Both the "Holy Grail" and the catalyst used for summoning can be regarded as "holy relics" and should be subject to the management of the church, so the position of supervisor was established.
However, this was only a superficial statement. The truth was that the three families of Tōsaka, Matou, and Einzbern deliberately leaked the news to the church in order to maintain order and balance and to check and balance the Magician Association, making them work for nothing.
Kallen didn't know the origin of the Supervisor. Even if she knew, she wouldn't care. After all, the Supervisor was just a cover, and she had only one goal - to kill the heretic named Kotomine Kirei.
The story of why she became the supervisor started with an encounter at the British border (see the end of the first volume of Shinji's Case Files for details).
Before Xiel attacked Roa, he had actually been lurking for a while. He heard part of the conversation between Roa and Araya and knew that they were going to attack a ritual called "Holy Grail War" next. It seemed that winning the war and obtaining the "Great Holy Grail" would open the way to the "Root".
Hier, who inherited the memory of Roa XVII, knows very well what "root" means to a magician. This is by no means a situation that can be left alone. Moreover, both she and Kallen have a deep hatred for Roa or Kotomine Kirei. For both public and private reasons, they must defeat Roa as soon as possible.
After escaping from danger, Hiel immediately used the agency's privileges to launch an investigation. However, the covert work of Tousaka, Matou, and Einzbern was so good that the church's knowledge of the "Holy Grail War" only remained at "a small-scale magic ceremony in the Far East", and there were only a few records in the files of the intelligence department, and no valuable information could be found at all.
At that time, Xier even suspected that he had been deceived. Luoa had already discovered his existence and deliberately said these words to mislead him.
So she went to Fiore to complain.
This woman who I just met has a certain strange charm that can calm people down in an incredible way. After the battle with Roa and Araya, they have been together.
At first, it was because Kallen's injuries had not healed and she had difficulty moving, and Fiore was worried about Xiel acting alone. Later, it was because of the issue of the Holy Grail War.
However, this time, not only did Xiel fail to calm down, but she became even more excited—because Fiore said she knew the inside story of the Holy Grail War. Although she couldn't explain in detail, she was sure that Roa was not lying, and now was indeed the time for the Holy Grail War. If you don't believe it, you can ask the "Eighth Mystery Society", they should have received an invitation to send a supervisor.
When Xier checked, it turned out to be true. Now she and Kallen could not sit still. While trying to get more useful information from Fiore, she submitted an action application to Narubalek. It was during this period that Fiore and Narubalek met and had a brief conversation.
At the end of the conversation, Narubalek finally agreed to Hiel's application and agreed that she and Kallen would go to Fuyuki as nuns and Holy Grail War supervisors. Meiren stayed behind to deal with the remaining issues of Fuhailin, and formally invited Fiore in the name of the director of the "Burying Agency", hoping that she would join the Burial Agency.
After receiving the usual reply of "I'm just a wandering magician and have no intention of belonging to any organization", the invitation to join was changed to an invitation to cooperate. This time, Fiore did not refuse.
By the way, the surveillance of Japan has always been in the charge of the "Inquisition Knights", and the fact that the "Burial Agency" borrowed the quota of the "Eighth Secret Society" to send supervisors naturally reached Lizbeife's ears. The chairman of the board of directors of Reien Girls' Academy and the "Holy Shield Knight" was bored, and when he heard that the "Burial Agency" was coming to his territory, he immediately became interested. He threw away the things at hand and rushed to Fuyuki as quickly as possible, and also brought the items that were taken away and sealed during the search - the "Spiritual Instrument Disk" mentioned by Xiye and Kallen in the conversation.
At first, Xiel and Kallen did not want to accept this colleague with whom they had no connection, but Liz Baife was surprisingly resilient in this regard. In order to join, she even agreed to such a harsh condition of "obeying orders in all actions". The two of them no longer insisted. After all, Liz Baife was one of the top fighters in the church. With her help, the success rate of the crusade would be greatly improved.
After playing a little trick on Lizbeife, Karen's mood obviously improved a lot. She coughed and explained seriously:
"Although it is a borrowed identity, I must do my job as a supervisor well."
The main job of the Supervisor is to monitor the progress of the war and to conceal magic and miracles so that they are not witnessed by ordinary people. In addition, they are also responsible for "protecting the defeated" and dealing with various accidents. When necessary, they even have the right to temporarily change the rules of the Holy Grail War.
"In principle, we are not allowed to intervene in the ceremony without the Master's request or in case of emergencies."
"I see."
Liz Baife slumped back on the bench in disappointment, but was cheered up by what Hieler said next.
"Roa's involvement itself was an emergency."
"you mean-?"
"No Master has such a poisonous snake lurking in the dark. As long as we can confirm his existence, we can unite with other Masters to defeat him. Then..."
"Can I challenge the servants of these masters?"
"Well, if the master and servant you challenge agree, it's not impossible, but that's not what I mean. I want you to deal with Roa's servants. Miss Fiore said that only those who participate in the battle are eligible to obtain the Holy Grail. If Roa wants to obtain the Holy Grail, there must be a master and servant participating in the battle, either himself or his allies. Before that, please be patient for the time being. If you really can't bear it, go and defeat the nearby vampires to kill time."
Having said that, Xier pushed up the camouflage glasses on his nose to hide the cold light that flashed in his eyes.
"In addition to Roa, many vampires have poured into this country and are active in this generation. Kallen and I must remain hidden and cannot be exposed easily, but you are different. You are often active in Japan, and no one will suspect you if you come forward to fight against them."
"Okay, I'll listen to you. Let's use these vampires as appetizers first! I'll make up for the number of subjugation you've missed."
The "Holy Shield Knight" is full of energy.
