Have a good day, Vice Principal. See you in class, Seraphina."
"Goodbye, sir Caelum."
"...yes... brother."
After we gave our goodbyes to each other, the vice principal awkwardly left my room, and Seraphina —whose face was considerably pale — meekly spoke and she also turned her back to leave.
"..."
I quietly entered back to my room and closed the door. Leaning against the door I couldn't help but smile and hide my smile with my hand.
"Heh..."
Seraphina was so cute and funny when she was so scared like that. Even though she somehow ended up as a killer, she was still my cute little sister. What kind of a lame older brother I would be if I didn't find my sister's scared expression cute?
'She failed to suppress her curiosity.'
After noticing that Seraphina's eyes were the eyes of killer, I decided to mature her mentality.
A killer would be always a killer, there was no way to restore her innocent, pure self from her killer self.
But!
Not all killers were the same. Most of them had a few distinctive characteristics that varied from one to another.
My goal was to only impart the relatively 'good' characteristics of killers. In short, I wanted to make her a killer with a conscience, a killer that could suppress her desires — curiosity, bloodlust, rage, etc — in check.
There was nothing I could do to restore Seraphina's former self, but with this slightly twisted way, I could make her close to normal.
'It is definitely better than being a serial killer that always runs away from the knights and hides in the sewers, or a curious thief that sneaks inside somewhere they shouldn't do and dies on the spot.'
I was talking from the experience.
I wasn't a serial killer or a curious thief, but the 'knight' that killed them. After all, I was a legal killer of the empire while they were illegal ones — lawbreakers. Leaving oneself's back to the government had advantages and disadvantages.
Anyway, the important matter was that Seraphina couldn't suppress her curiosity.
Just a moment ago when we — I, Seraphina, and the Vice Principal — were in my living room, I intentionally mentioned her to not not go inside two rooms, my interrogation room and trophy room.
Well, like I have said, she failed and entered the interrogation room. She was lucky to enter that room instead of the other one. I was sure that I would laugh heartily if she were to enter the trophy room and scream like a little girl. That would be definitely a cute sight to see.
'Well well, let's hope that she was just being careless because she was in my room instead of a stranger's.'
'Curiosity will always kill the cat, if it doesn't die today then it will die tomorrow or another day.'
'I should speak with Seraphina about being a killer and learn how she became one.'
'Also, I should burn the teddy bear.'
"Sigh... There is too much thing to do. I need to observe the so-called protagonist of the world, Lars too. There must be a reason Mother stopped me from killing an idiotic guy like that.'
"Right, Mother?" I whispered gently to my right while caressing the black, inverted bone cross.

"Left! Left! Left! Left! Left! Left! Left!" A loud, strong voice reverberated in the training area.
The students — it didn't matter if they were mages or knights — were walking nonstop for the past hour. They were learning to walk like soldiers.
Being systematic was usually a good thing for the cannon fodders, hence I normally would approve this taking a step at the same times as your teammates did. However, this was simply worthless to this 'Royal' class.
These students were not cannon fodders but a bunch of talented people who were going to be the heads of their respectable noble households.
Plus, this was a bit unfair toward the magic-focused students. Their body was just slightly stronger than normal humans.
Hence, the mage students were already on the dirt ground, breathing loudly like wild beasts.
Though, my gaze was on the two different people. One of them was Seraphina while the other one was Lars Lightbringer.
'Did she receive any physical training while I was away?'
Among the mages, Seraphina was one of the physically strongest. I felt a bit proud to see her keep up with the knights who usually trained their bodies, unlike the mages.
'That is my sister for you, you fools!'
Internally mocking the other people, I improved my mood and turned my attention to Lars.
Unlike Seraphina, Lars was a knight, but how pathetic he was to be in worse shape than my sister.
'Maybe Seraphina is just that good?'
Quickly suppressing my overflowing proud brotherly feelings, I calmly observed Lars and his mind.
[Is there a skip button or something? Why the fuck I need to walk like a robot for a fucking two hours!]
'He is still complaining. I wonder how he even managed to get into this class. His talent and potential must be amazing for him with his sloppy body and skills.'
I leaned my back against a tree with a natural movement and closed my eyes. Taking deep breaths, I increased my concentration and very carefully unlocked one of the small seals that was limiting my mind reading.
As for why there were seals on my mind-reading ability, because mind reading was a both blessing and a curse.
Essentially, calling 'Mind Reading ability' was wrong, the right term would be a mind without borders.
According to my guesses and research, every mind has its borders. It didn't matter if the owner of the mind was an intelligent being or a wild beast. These borders were there to protect the mind from other minds — or I assumed so.
Hence, I, who has no borders in mind, couldn't protect my mind from other minds. Without borders, my mind was similar to air, every mind could walk on my mind like they were taking a light stroll — plus they could somehow learn things about me — and I could also envelope or infiltrate other minds, or scatter around like a pile of dust in front of a slight breeze, and go mad.
The seals were like a man–made, no, goddess-made borders of my mind. I was still sane because of these seals, so I was always grateful and careful when slightly opening the seals.
After all, I was too young to go mad.
As for why I was opening a seal, I wanted to infiltrate more deeply into Lars's mind instead of just reading his surface thoughts.
I needed to learn everything about him. I didn't need torture or persuasion, my mind was vastly more effective than both of them combined.
