In a rented room at the school, I talked to a girl knight who came to report to me.
　--Yesterday, there was an incident. The incident occurred yesterday in "Fenkor," a district controlled by the Kuro Wolf Knights, and "Orenso," a district controlled by the Knights of the Holy Armor.
　There were three knights affected, all of whom were skilled first-class officers. One of them, Zaeeda Ebel, a first class officer belonging to the Kuro Wolf Knights, is missing.
　According to the report of the knight who was with her, she disappeared after a battle with a knight in jet black armor.
　Based on the amount of blood left at the scene and the absence of the knight, it is highly likely that she was murdered and her body was recovered, according to the knight who examined the scene.
　In the event that you're not sure what to do, you may want to check with your doctor.

I understand what you're saying. So, I want at least two knights of the first class and above to be on special alert. ...... Is that what you're saying?
Yes, sir!　I'm not sure what to make of that. It's unprecedented that three first-class officers are killed in one night.

　The girl knight is right.
　In the kingdom's knightly orders, first officer is a rank given to knights of high ability.
　In the case of the Kuro Wolf Knights, there are only a few, including myself.
　The two knights who were confirmed to have been killed were first class officers of the Knights of the Holy Armor, and it seems that a complete high alert has been set up over there.
　--The two knights were the first officers of the Holy Armor Knights, and they were on full alert over there.
　And that would be a heavy burden for Remyll, who manages both knight orders.
　That may be why he sent a knight to contact me as soon as possible.

"First Officer Alta Schweizer has been instructed to take precautions around the school. I'm sure you'll be happy to hear that.
"...... Well... I'm going to try to stay away from the school as much as I can, but that's just the way it usually is. I'm not sure what to make of this.
Yes!　That's me!

　The girl knight answered my question with a cheerful salute.
　I was a little surprised and looked at her again.
　I can't believe I'm saying this now, but she looks pretty young. She's probably a little older than Iris and the others.
　From what I heard earlier, there are two first class officers. .......

So you're saying you're a first class officer too?
Yes, I am!　...... Oh, by the way, I haven't even told you my name yet!　I beg your pardon!　I'm Helen Trousseau, and I just recently rose to the rank of first officer in the Order of the Holy Armor!
I see, you're Helen of the Knights of the Holy Armor.　"Helen Torso?

　I couldn't help but ask the name back.
　I'm not sure what to make of it.

I'm not sure if you've heard of her, but I'm sure you've heard of her. ...... You may not have known her very well, but do you remember Belle Trousseau, the first class knight who belonged to the Kuro Wolf Knights?　Belle is my brother.
"I see. So you are Belle's sister?

　Helen was right, I did not know Belle.
The Blue Sword, that was his alias. With a sword strike so fast that it was called the "blue flash," Belle Trousseau was surely the strongest knight with a promising future in the Kuro Wolf Knights before I joined.
　In fact, even after his death in the battle against the Swordsmen, I have sometimes heard people regretting his death.
　However, I had never heard that he had a sister.
　I hadn't heard that he had a younger sister, but that he had risen to the rank of first class knight like Belle, and that they were both undeniably talented.
　As I was thinking about what I should say to her, Helen opened her mouth first.

I'm sure you don't mind my brother, do you?　There are many people in the Kuro Wolf Knights who have a gloomy look on their face when they hear my name in particular,......, but my brother fought well as a knight. It's a good thing that you're not the only one who has a problem with this.
...... If that's the case. You're right, I didn't know him very well, but I still hear his name. I'm sure he was a great knight.
I'm sure my brother would be happy to hear you say that, Alta-san!　I'm sure my brother will be happy to hear that, because Arta is the current "youngest knight", right?　I've heard that my brother is a little bit conscious of me before. I'm also a little - no, a lot - conscious of it!　It's melamela!

　Helen clenched her fists.
　I've heard about Bell from Lemire, but my impression of him was that he was a rather quiet young man. In contrast, her sister, Helen, has a much brighter personality ...... and can be described as hot-blooded.

I'm not that big of a deal. I'm a fellow knight who will be working with you. I'm not a big fan of that, but I'm a fellow knight who's going to be working with you. Let's work together to fulfill our duties as knights.
"......!　Yes!　I'm looking forward to working with you!

　I shook hands with Helen firmly.
　-Knight's murder. I don't know what my intentions are, but I have a man in my mind.
　The man who calls himself Raoul Isaruf, Aena tells me. I'm sure he'd be no match for a first class knight.
I'm sure you'll be able to find something that works for you. ......, but three knights were attacked at almost the same time. If there is a connection, then there are several other skilled swordsmen on the enemy side.
It is unlikely that there are multiple 《Kensei》class swordsmen, but in any case, there is no doubt that the enemy is quite capable.
　I was going to tell Remyll about my cooperation with Aena, but now that I've sent Helen, I don't think I'll be able to talk to her for a while.


　I'll have to check on Lemire's movements, just in case.

I'd like to ask you a question. Is Commander Ein in Orenso now?
Yes, I've been keeping my hands busy over there dealing with this matter, but ...... he said he had a 'plan' for this matter!　I don't know the details, but I'm sure they'll contact me if there are any developments.
"I see, I understand. I see, I understand. Now, shall we act on our own?
"Yes!

　Helen answered cheerfully with a smile.
　I'm not sure what to make of it. It's a good idea to take a look at the website and see if you can find any useful information about it. ...... If you don't know what the enemy is trying to do, you don't want to push yourself too hard, but if she has an idea, you'll have to wait for her to report it.
