CHAPTER 245: TRUE DISCIPLINE (3)

0% Most students stopped writing at that, but there was one exception.

Yufiel Vierbein.

I could sense a fiery determination from that studious girl that she was going to write it down without a single mistake.

“Hmm.”

Her Mana Depletion was already a problem, yet she also didn’t seem to have a good study method.

It’d be different if it was to study for entrance exams, but in university, simply memorizing and taking good notes wasn’t going to get you good grades.

It could work for some professors’ courses, of course, but it wasn’t an appropriate study method to maintain throughout.

“Writing it down isn’t the important part, everyone. First try to listen and understand. The formula itself is shown in more detail in the textbook.”

Although the formula derived just now was the conclusion, it wasn’t the point. The main point of this lecture was to understand parity.

“If you differentiate the equation, the rate of change isn’t zero, right? This is all you need to know–that our eyes themselves have curvature, which means the symmetry is broken.”

There was no symmetry in the parity transformation. Symmetry was broken. Nothing was conserved.

“Do you see where I’m going, everyone?”

There was an ‘ah’ from somewhere.

“So the variational theory that you taught the first class.......”

The person who spoke was none other than Vermel.

It was unexpected–to think that he’d ask a perceptive question like that.

I nodded without outwardly expressing it.

“As you can see, there are several factors that can break parity symmetry. Even I don’t know how many there are. So isn’t it better to set the variable to infinity, calculate the ‘variation’ at each point to derive a generalized expression first, then apply it to special cases?”

One by one, a few students gasped.

Some were surprised, and others flipped to their earlier notes. Yufiel closed her notebook and began looking through the textbook.

This was the highlight.

“This is what people call a generalization... or in other words, a theory.”

Theory.

In the end, I came all this way to say that the explicit understanding of theories was important.

[Why didn’t you say so from the beginning?]

Simple.

Because people didn’t like it when you started with theory.

Originally, saying the most important thing at the end was a decent method, but making the other person realize without actually saying it was the best method.

And saying it before the other person became curious about it only made them lose interest, which was a way of teaching that wasn’t really recommended.

[...Oho.]

I decided to take a roundabout approach so that it’d leave an impression on the students.

“I didn’t teach you the variational theory of multivariate function in the first class, as deriving the Euler-Lagrange equation alone would’ve been overwhelming. Of course, I proved all sorts of complicated things like lemmas and such in the process, but there was only one conclusion.”

The understanding of parity.

The students’ expressions changed. There wasn’t anyone who was bored or nodding off like last time.

Not that there was anyone smiling big or with upturned lips, but I could tell just by looking at their eyes.

The students were beginning to think deeper.

“In the next class, I’ll be showing you what symmetry and conservation by proving with variational theory.”

With that, I stepped down from the platform. My throat was a little hoarse since I hadn’t had to talk that much in a while.

The class bell went off just then, too. I figured I could hand back the controls and go eat now.

But.

“Miss, I have a question.”

“Me, too....”

“Same!”

The students came forward one by one with their textbooks, blocking the way out.

Ah, no, this can’t be.

There’s a limited edition salmon dish on today’s menu.

**Sis was weird today.

She had asked her to tie her hair into a ponytail which she usually did just fine herself, and her careful walking was off somehow.

Her lecturing style even changed to something student-friendly.

This couldn’t be happening.

Her twin sister, who would clench her teeth whenever she saw humans or elves after what happened at Tilette, was regarding the students with a light smile after a long time....

Golden-Eyeds were poor at expressing emotions due to the ‘Curse of Ironization’. As such, they would think and express themselves like machines.

But that looked–

“Human....”

Like a human.

As if her body was the same but the soul had changed.

“Ah.”

Akasha recalled what she had heard at the Demon Castle.

─There are two souls. It’s faint, but one is letting the other have control on purpose.

It was what Klara Hasfeldt, the older sister of Klais Hasfeldt, had said.

Klara was an Elemental Mage who had a sensitive perception of souls. There wouldn’t be any falsehood in her words.

Which meant that her sister had a split personality, and could pull out the other personality at any time and improvise as needed.

“I see.”

Akasha grinned as Aether was teaching.

The first to detect change in a twin was the other twin. Akasha and Aether had been together since young, and knew each other better than anyone.

Yes, as if looking into a mirror.

She could easily look into what kind of state her sister was in like ripping open flesh with a sharp spear.

“This is the end of class.”

As soon as she said that, the class bell rang. Akasha packed up her pens and rose from her seat.

Right then, the students all rushed forward. She thought it was to go eat today’s special menu, the salmon donburi, but that wasn’t it.

Most of them were blocking the door. Surrounding Aether, they began asking questions in turns as if learning was more important than food.

Lotte, Freyr, and Vermel were also amongst the students who were asking questions.

“Isn’t it fascinating?”

“Hm?”

Someone came up to her.

It was a beautiful girl with burgundy hair and gold eyes. Akasha knew who she was.

“Leninya.”

Leninya held out a star candy towards her. Akasha took it without question and listened to what followed.

“Miss Heisenberg, I mean. She seems completely different from yesterday.”

“Everyone else probably thinks that, too.”

The usual Aether would’ve taken off before the students could stop her.

“I don’t why she suddenly changed like this, but I think it’s a good thing.”

Akasha nodded slightly at Leninya’s words.

A good thing, eh.

“Definitely.”

If her sister’s temper could be tamed even a little, then they could avoid world destruction.

Her sister had been out of her mind until now. Seriously, how could she burn the world that she herself was living in?

It was really too much, no? Even the Demon King wouldn’t do that.

“By the way, Rakia.”

“Yeah?”

Rakia was Akasha’s fake name.

“Vermel told me to give this to you.”

Leninya held out a scrap paper to her; it looked like a piece of paper had been ripped out from a notebook and folded after scribbling something hastily.

“To me? Why?”

“How would I know.”

It was too sloppy for a love letter. It looked like it was hastily put together, and something like that should be given in person.

Akasha remembered that Vermel and Aether used to hang out in the past.

Rosemary had said that there was ‘something’ between them that they weren’t privy to. She didn’t know exactly, but Akasha speculated that it was a bond.

And if it was a bond, then what kind of bond? How and when had it formed?

It wasn’t that hard to get the answer.

“...It was the other personality.”

“Did you say something?”

“No, it’s nothing.”

Akasha took the letter and opened it.

Then she huffed a laugh at the absurdity.

“What does it say?”

“Hmm.”

“You don’t have to tell me if it’s difficult.”

“No, no.”

Akasha showed her the note. Leninya’s expression turned into someone who was struck speechless.

“He wants to meet me in front of the dorms.”

“Isn’t this a love letter?”

Akasha shook her head.

“What kind of moron would write and send a letter like this to the person they’re interested in?”

“That’s true.”

‘Then what is it’, Leninya seemed to be pondering, but soon lost interest. She was occupied with meeting others and handing out star candies.

Why on earth was she handing out those things? She just couldn’t understand it.

“Hmm.”

Anyway, there were two possibilities.

Either reveal her identity and screw her over.

Or ask for her cooperation.

Either way, it was troubling. Akasha went ‘haaa’, letting out a sigh. In the meanwhile, Aether answered all the students’ questions and made her way towards the cafeteria.

“Right, salmon.”

They said that today’s limited edition menu was salmon.

There was a limited number so she wouldn’t be able to eat it if she didn’t get there quickly.

She’d think about complicated matters while eating, Akasha decided, and rushed to the cafeteria.

**After school.

As she neared the entrance to the student dorms, an elf came into view.

Tall, handsome. It was said that there were many beauties amongst the elves, but this student was one of the best-looking.

Akasha felt no attraction even when she saw him.

The Demon Army despised elves out of all other races. Bastards who were all boastful because they were favored by Elementals. They all needed to be off with their heads.

Today especially.

“Fucking bastard.”

She missed out on tasting high-quality salmon with evenly distributed fat because of this fucker.

Of course, it was actually because Akasha had been late that she didn’t get to eat it, but... Anyway, it was because of that elf.

Vermel Horde.

He must have seen her because he was slowly walking over here.

Step.

The two were now alone.

“You really came.”

“You, you know who I am, don’t you?”

“Indeed I do.”

“If you’ve called me here for something trivial, you’re going to be dead meat.”

A curve stretched across Vermel’s lips.

“You won’t be disappointed.”

Then he held out another letter.

It was a proper letter this time. The envelope was sealed with the emblem of the Philut Empire and was colored gold in places.

So there was something.

After looking around, Akasha snatched the letter. She carefully peeled off the wax with her nail and checked the contents.

Inside, there was a single-page letter with a photo.

“This is...?”

The photo showed a girl who was doing a headstand1.

It was Rosemary.
