Editing Unlimited Fafnir:Volume 2 Chapter 1 (section)

===Part 1===

—A sharp pain.

A sharp pain ran across the back of my left hand, lifting my consciousness from the abyss of deep sleep.

Opening my eyelids, I saw dawn's rays entering through the window, shining mercilessly into my eyes, forcing me to squint.

I checked out my left hand's state, which felt like I had been bitten by a bug.

On the back of my left hand was a birthmark with a distinct shape. This dragon mark was present somewhere on the body of every person capable of generating dark matter—commonly known as Ds. Its size was directly proportional to one's dark matter generating capacity. My dragon mark was extremely small.

That tiny dragon mark was my proof as an inferior D. And next to that dragon mark, a small red swelling had appeared.

I probably bruised it accidentally while I was sleeping.

The wound was itching but I used that hand to search next to my pillow, holding back the urge to scratch it. 

Touching the alarm clock with my fingertips, I brought it before my eyes to check the time.

6:10am.

Because I normally set my alarm at 6:30am, this meant that I had woken up slightly earlier than usual.

But the lingering drowsiness was not enough to make me want to lie in bed.

"...It's good to get up early once in a while."

I got off the bed and walked to the washroom, only to see my familiar face reflected in the mirror.

Perhaps due to just waking up, my eyes seemed more vicious than usual.

On the other side of the mirror, a young man was scowling and staring at me. Named Mononobe Yuu, he was sixteen years of age, ranked 2nd Lieutenant.

Arrested at the age of thirteen due to his identity as a D, he was assigned to a military organization—NIFL.

For three years, he had fought in various lands as a member of the special team Sleipnir. Finally, a month ago, he was reassigned to Midgard.

No—More accurately, he was ''transferred''.

This Midgard was a ''school'', converted from an uninhabited island far south of Japan, the self-governed educational institute of the Ds. Mononobe Yuu was currently living here as a student of Midgard Academy.

After washing my face with cold water, I felt my expression tense up.

I returned to my room and changed into the school's uniform.

—THUD!

Just as I was tightening my belt, I heard a massive crash coming from above.

"What...?"

I looked up at the ceiling and muttered. Directly above was the room my younger sister Mitsuki used.

Beginning to worry, I swiftly finished changing and exited my room, then went through the entrance hall to reach the second floor, arriving in front of Mitsuki's room.

"Hey, Mitsuki! Did something happen?"

"Eh? N-Nii-san? I-I am fine, so—kyah!?"

While hearing a scream from the other side of the door, I heard another massive crash.

"Mitsuki!?"

I instantly opened the door.

Perhaps because the entire dorm belonged to Mitsuki, she had grown a bit careless. Mitsuki frequently did not lock her door.

I rushed into the room but was met by an unexpected sight.

Underwear of all colors was scattered inside the room while my younger sister was naked, buried in a pile of underwear. A drawer from a set of drawers was overturned completely.

Mitsuki had her hand pressed against her head and looked like she was in pain. Discovering I had entered the room, she looked up.

"W-What—"

Her snow-white skin, visible between gaps in her gorgeous long black hair and the large amount of underwear, turned scarlet from embarrassment.

Mitsuki grabbed nearby underwear to cover up her petite yet beautifully shaped breasts and glared at me. But due to the pair of striped panties on her head, she did not look intimidating at all.

I crossed my arms and reconfirmed the situation in the room.

"Uh... It feels like you were trying to get underwear from the top drawer, but lost balance and overturned it? And it even happened twice?"

"W-What are you calmly analyzing the situation for!? The second time happened because just as I was putting the drawer back, Nii-san, you suddenly appeared! No, I should ask you to leave now!!"

Mitsuki, the student council president, harshly commanded me to leave, but I did not follow her orders. Instead, I approached her while she was buried in the pile of underwear.

"Sorry, Mitsuki, before I leave, let me have a look first."

"Eh...? N-Nii-san? What are you looking at—"

Mitsuki looked up at me in her naked state. I knelt down before her and lifted up her long black hair with my hand.

"Ah... Nii-san, no... Something like that—"

With her face bright red, Mitsuki shook her head slightly in refusal but did not resist in any other way.

I brought her head closer as though about to hug her head. Using my fingers to comb and push her long black hair away, I searched the beneath her hair.

"Nn... We still have not... The promise—Hold on, Nii-san..."

Mitsuki squirmed and exhaled hot breath.

As my fingers reached the minor bulge I was looking for, Mitsuki instantly shook.

"—Does it hurt? Although there's no bleeding... It's a bit swollen. Hold on, I'll get some ice."

Saying that, I separated from Mitsuki.

"...Eh? What is the meaning of this, Nii-san?"

Mitsuki looked up at me in surprise.

"What do you mean, what is the meaning of this? I was checking your injury. You bumped your head, right?"

"Right... Ah, ahhh, I see what was going on now, and I even thought—"

Mitsuki lowered her head in embarrassment.

"Thought what?"

Hearing me ask that, Mitsuki blushed so much that even her ears went red. She shook her head.

"N-Nothing at all!"

Sulking, Mitsuki turned her head away.

Despite her incomprehensible reaction, I still went to the kitchen to fetch an ice pack.



Twenty-five years ago, a giant creature suddenly appeared in the sky above Japan.

Simply by moving, that monster caused severe calamities. Using a supernatural power capable of conjuring matter out of thin air, the monster was able to neutralize every kind of attack the humans threw at it.

Then as though mocking the humans who resisted in desperation, the monster leisurely traveled once around the world and vanished into thin air without warning.

Thereafter, children possessing the same power as the monster became born among the humans. They were known as producers and users of dark matter, the Ds, or Type Dragon.

There was an extremely high economic value in their ability to create any type of matter arbitrarily. Reportedly, wars even broke out in the past in struggles to obtain Ds.

And during the same period while the Ds were born, new types of giant organisms appeared in the world.

These monsters with powers beyond human imagination were called dragons by the world. An international organization, Asgard, was established specifically to deal with dragons.

Asgard reorganized the United Nations troops into NIFL, a military force that could operate outside of conventional laws, trying to use military intervention to resolve various problems caused by dragons.

Due to the fact that the Ds were designated as one of the problems caused by dragons, an isolation facility was constructed on an uninhabited island near the equator, namely, Midgard in its infancy.

When it was first established, Midgard's purpose leaned closer to detainment, but as the Ds grew up and increased in number, their voices grew in strength and they finally won human rights and autonomy.

Hence, Midgard became the current state... But for some unknown reason, all humans born as Ds were female, hence, Midgard inevitably became an all-girls school.

However, I was enrolled in that kind of secret garden.

That was because I, too, possessed the power to generate dark matter.

Currently the only male D in the world, that was me—Mononobe Yuu.

Or perhaps because I was an exception, back when I was arrested three years ago, they did not send me to Midgard. Instead, I was cultivated as a soldier in NIFL.

But one month ago, I was suddenly reassigned to Midgard.

That was arranged by my younger sister Mitsuki who had amassed substantial authority in Midgard.

Ever since, I lived a school life under Mitsuki's ''supervision''.

As I was the only male in the school, to prevent problems arising because of me, Mitsuki made me live in her dorm, separate from ordinary dorms.

—Hence, walking to school like this with Mitsuki together had gradually become my daily life each morning.

"You have been acting a bit weird lately, Nii-san."

After breakfast, the two of us left the dorm together. On the way to school, Mitsuki remarked unhappily.

Because there was a long way to go before the path converged with that of ordinary dorms, no other students could be seen in our surroundings.

The road followed the breakwater on the shore, tracing out a gentle curve. The other side of the breakwater was a vast stretch of blue sea and white sands.

The only sounds were that of the waves, the coconut trees swaying in the wind, and the footsteps from Mitsuki and me.

"How am I weird?"

Since I had no clue, I asked her honestly.

Mitsuki kept switching hands to carry her schoolbag as though she could not settle down, then she looked up at me.

"How should I put this...? Recently, Nii-san, you have been acting without delicacy, such as entering my room without knocking, approaching me nonchalantly while I was naked... I believe you are acting a bit too unreserved."

"...? Siblings aren't supposed to act reserved to each other, right? Are you asking me to act more distant towards you, Mitsuki?"

Unable to understand Mitsuki's allegations, I frowned and asked.

"That is not what I mean..."

Mitsuki frantically lowered her head. She seemed unable to explain clearly.

—Was there something wrong with my behavior?

But even after thinking back to scrutinize my behavior, I still did not think I did anything wrong.

But... There was only one reason that could explain why Mitsuki had this feeling.

Two weeks ago, during the battle against the white dragon—"White" Leviathan—that was invading Midgard, I took a slight risk.

In order to break out of the crisis, I accepted ''knowledge of power'' that eroded my personality and memories.

But the most important information to me right now—everything that had happened after arriving at Midgard—I should not have forgotten any of it. I also knew clearly about my little sister Mitsuki. My memories at NIFL also remained vivid.

However, it was also possible that I was simply unaware of it. I might have ''changed in nature'' in fact.

Three years ago, apart from memories related to Mitsuki, all my other memories were eroded to oblivion. My emotion of fear had also become extremely diluted. Perhaps just like that time, the personality named Mononobe Yuu had become even more distant from me.

"...Nii-san, what is the matter with you?"

Seeing me silent, Mitsuki made a worried expression and peered at my face from below.

—No good. I can't let Mitsuki worry. Mitsuki was the one person I absolutely must not allow to find out.

Because if she knew what I had lost as the price, Mitsuki would surely blame herself.

Hence, I switched my consciousness and changed the subject cheerfully.

"Hmm? Oh, I was recalling what happened this morning. I wanted to say that you've grown quite a bit over the past three years, Mitsuki."

Immediately, Mitsuki went red in the face.

"P-Please do not reminisce about that! I-If you were to repeat the same words in school, Nii-san, I shall have to punish you for sexual harassment! You will be punished to write ten repentance essays!"

"Man... I don't ever want to write another repentance essay again. Give me a break."

Due to insubordination in the previous battle, I was punished to write almost a hundred repentance essays. To be honest, it made me suffer even more than NIFL's training.

"Then please think very carefully before you speak."

"...Affirmative, student council president. But what happened this morning really doesn't seem like a blunder you'd make, Mitsuki. Shouldn't daily necessities like underwear be kept somewhere easier to reach?"

The drawer Mitsuki had dropped on the ground was the top drawer—It was at a height that she could barely reach on tiptoe. Hence it came as no surprise that she overturned it.

"That is... a drawer I normally have no need to use. It is for keeping slightly special underwear."

"Special? So it's what people call victory underwear?"

Hearing me ask that, Mitsuki frowned.

"Another statement filled with the flavor of sexual harassment... Sigh, as much as I hate to admit it, perhaps that does come close in meaning. Because in a certain sense, it is underwear used for battle."

"Battle, you say? Against what?"

Hearing me ask with curiosity, Mitsuki answered with a slightly solemn expression.

"Although ordinary students have not been informed yet, an impromptu health examination will actually be held today. In order to maintain the integrity of the student council president's dignity after undressing, I must exercise extra caution on the matter of underwear."

Finding out about Mitsuki's secret efforts, I sighed.

"...Life must be tough being the student council president. But these random sampling health examinations... Are they frequent in Midgard?"

I still had yet to get a grasp on Midgard's common knowledge, so I asked Mitsuki this question.

"No, this is the first time."

"Is there a reason for doing this?"

I asked immediately, only to see Mitsuki nod in admission.

"—Indeed there is a reason, but I cannot reveal it yet."

Seeing her put on her student council president's face, refusing firmly to reveal the truth, it was very hard for me to pry further.

Hence, I gave up asking the reason and turned my gaze forward.

On the other side of the flourishing jungle, I could catch a glimpse of the tip of the clock tower, the school's symbol.

Feeling like something was about to happen, walking with Mitsuki side by side, I made my way along the path to the school for Ds—
