Prologue

A boy wandered through the endless passages of the Instructional School while carrying an ominously dark sword. Though he was a boy, he had beautiful, waist-length ebony hair and a girlish appearance. If asked, 10 out of 10 civilians would say he was a "stunningly beautiful young girl with cold, uncaring eyes". However, he was only ever seen by those of the Instructional School, and perhaps a few "targets" right before their deaths.

After all, this boy was an assassin and not just any assassin either. He was the best in the Instructional School, a secret organization based in the Ordesian Empire that trained assassins from a young age. It was an organization that worshipped the Demon King Solomon, and

Spirits only make contracts with pure maidens. This was a fact that has only ever been overturned by the Demon King Solomon. Solomon was a tyrant who ruled hundreds of years ago who ruled the continent with an iron fist with the power of 72 demon spirits. He was eventually overthrown by the Sacred Queen Areishia Idriss, but before his death, he had established many secret organizations to support his reign, such as the Instructional School. Thus, when the Instructional School discovered this boy, Kamito Kazehaya, they wasted no effort in raising him to become the successor of Demon King.

However, now the Instructional School was being attacked by an unknown entity, a strange colossus made of fire. Just minutes after the attack, it had already killed most of members of the Instructional School. At this point, the organization had already ceased to exist.

Regardless, Kamito was not seeking to escape the giant. In fact, he was striding decisively towards it.

"Why are we attacking the giant again?"

A voice resounded in Kamito's head. Though the source could not be discerned with his ears, Kamito knew it came from his trust worthy sword.

"I'm not sure myself Restia" the boy replied, "I just have this feeling that I have to fight it"

"…"

This confused both Restia and Kamito. Kamito should have had all his emotions taken away by the Instructional School. The only emotions that he felt were those that he had been taught by Restia. Any desire to battle this giant should not exist.

"Onii-sama!"

Before the two could ponder the issue anymore, they were interrupted by the voice of a girl behind. She had ash-grey hair that was tied up on both sides of her head. Along with her blue clear pupils, her skin that could be seen from the gaps of her black combat uniform was white like virgin snow. She was the only person who called Kamito "onii-sama"

"Muir, you haven't escaped yet?"

"Nope, I was looking for you onii-sama" she answered with a pout.

Naturally, Kamito, who was an orphan, had no sisters. 'Onii-sama' was just something she called him willfully.

"Anyway, what are you still doing here onii-sama?" she asked curiously, with the same tone one would use when asking another how their day was .

"Ah, I was thinking of fighting that crimson giant over there" he replied.

"That outrageously strong flame spirit? Let me help onii-sama."

"Muir, that is not a being that a human can manage" Kamito said to Muir blandly. Even at this distance, Kamito could tell that the giant was at least an arch-demon class spirit.

"By that logic, shouldn't you run away as well then?"

"I don't think a Maou (Demon King) can really count as being human any more Restia…" Kamito thought to his sword "Besides I have you, the strongest demon sword, while Muir doesn't even have a contracted spirit".

"No problem. Muir isn't a human— Muir is a monster." Before Restia could provide a counter-argument, they were once again interrupted by Muir "I have the Jester's Vice after all. Plus I stole a few military spirits as well."

"What happened to the people guarding those?"

"I killed them" Muir replied matter-of-factly.

"I see" Kamito's words held no sympathy for the dead.

"Well I don't see any reason to not bring her along. If you insist on fighting that giant, her assistance could be helpful"

"That's true" Kamito replied. Muir wasn't known as a monster for no reason after all.

"Okay then Muir, let's go"
◊ ◊ ◊

The pair (plus sword) arrived at the location of the giant's rampage with no problems.

'Its even more overwhelming up-close' Kamito thought to himself.

"Ara, are you chickening out now Kamito?" Restia asked playfully.

"No. Before the feeling was vague, but now I can tell this spirit belongs to my enemy." Kamito was not sure himself what he was talking about but continued regardless "Muir, you ready?"

"Haaaaaai" An ominous spirit seal glowed on Muir's right hand.

No, that was not a spirit seal, but a Cursed Armament Seal that the Instruction School had given. «Jester's Vice» — It was the reason why Muir was called a «monster».

"Very well" Kamito began gathering power to his Vorpal Sword "Let's go then, Vorpal Blast!" Kamito yelled releasing a stream of jet-black lightning at his foe.
◊ ◊ ◊

Rubia Elstein was bored. Very bored.

The so-called Calamity Queen had finally tracked down the location of the Instructional School and had hoped to find a clue of the location of the Demon King or at least some powerful people to recruit to her cause.

However, everyone who went out to fight her spirit, Laevateinn was annihilated in seconds.

'Too weak' She thought to herself 'At this level, they wouldn't stand a chance against the five elemental lords. This was a waste of time'

Just as she was about to leave, she noticed two sources of great power approach Laevateinn.

One was a girl with ash-grey hair worn in twin-tails. The other was an overwhelmingly beautiful young girl with waist-length black hair. Though the grey-haired one radiated power, Rubia couldn't sense any energy at all from the black-haired girl. However, Rubia sensed from the depths of her soul that this girl was undoubtedly an enemy.

This confused her greatly. The only person she could have recognized as an enemy was the Demon King, but that person was certainly a girl. 'My senses must be confused' she thought 'when was the last time I had slept?'

Before she could ponder the issue any longer, the black-haired girl unleashed a surge of black lightning towards Laevateinn.

The giant roared with displeasure and swung its fist at the girls but by the time it reached, they had already jumped out of the way. The grey-haired girl waved her arm and summoned a giant, 8-headed, serpent spirit. One of its heads immediately tried to bite the fire giant and was instantly incinerated. The remaining heads, learning from their brother's mistake, attacked Laevateinn with jets of water. Though it wasn't nearly as strong as the flame giant, the serpent was still a military-grade spirit.

'That snake is definitely a water spirit of some kind' Rubia thought. She was more concerned, however, about what the other girl was doing, the one she had recognized as an enemy.

Rubia could neither see nor sense the other girl, but she could see flashes of darkness that surrounded her contracted spirit. Each flash would leave a large wound on the flame spirit and, though Laevateinn had powerful regeneration abilities, it was still clearly having trouble against the combined assault of the serpent and the sword-wielding girl. However…

'That still isn't enough," Rubia thought to herself 'though Laevateinn has a bad compatibility with that snake and that girl is using a powerful elemental waffe along with some strange sword techniques, but you'll have to do better than that to stop the strongest flame spirit. Are you really the one I've been looking for?'

Almost as if hearing Rubia's commentary the black-haired girl suddenly stopped in her tracks, and began generating an enormous amount of energy. She was covered with an ominous black aura that seemed to distort the area around her. It was as if the night sky had descended around the girl.
◊ ◊ ◊

Kamito was getting worried. Muir's Yamata no Orochi wasn't doing much damage to the flame giant despite having good compatibility against it and Muir wouldn't be able to use it much longer without either her or the water spirit falling apart.

Kamito himself was also having problems. He had been continuously using Shadow Weaving and Thunderclap to strike at the flame giant without being hit himself. Though this allowed him to fight the giant and remain unscathed, it was incredibly exhausting. Not to mention…

'Using the Vorpal Sword continuously really is energy consuming…' Kamito thought to himself.

"How cruel!", Restia responded melodramatically "even though I'm doing my best for you, all you can do is complain? But seriously, why in the world is Laevateinn here?"

"Laevateinn?", Kamito asked, "Restia, do you recognize this spirit?"

"Yeah, back in the Spirit War I saw this fellow quite a bit. He was the lieutenant of Volcanicus, the Fire Spirit lord, and was supposed to have been sealed after the war ended. As you may have noticed, he's quite strong. We won't stand a chance unless you use that."

"Very well then" Kamito responded, "I suppose there is no choice." He then began to chant:

"-The who gathers all shadows to her side, the one bestows terror upon her foolish foes and grants peace to her friends, Her name being, the Elemental Lord of Darkness - Ren Ashdoll"

From the depths of his soul, overwhelming power flowed in Kamito and his sword. An aura of pure darkness surrounded Kamito, one that was both menacing and calming at the same time. Feeling this intense aura Laevateinn began to back away in fear. At the same time, Muir dismissed her Yamata no Orochi, knowing that it was no longer necessary now that Kamito had gotten serious.

'Though it's nice to know you trust in me, I would appreciate if you helped, Muir…', Kamito thought to himself. 'Then again, pulling back is the right move. After all, I still can't completely control this power so she might get hit in the crossfire if she tried to help'

Gathering his power into his blade, Kamito lazily pointing the Vorpal Sword at Laevateinn and murmured in an almost bored tone,"Vorpal Blast". Lightning once again streamed towards the giant, but its intensity was incomparable to what he had released at the beginning of the battle. The crimson colossus was almost completely annihilated by the stream of jet-black lightning. It let out a pained groan, then disappeared.
◊ ◊ ◊

"Impressive as always onii-sama", Muir chirped, but upon seeing Kamito's troubled face she asked, "What's wrong onii-sama?"

"The feeling of the enemy has yet to disappear" he replied worriedly.

"Very impressive, Demon King. I've been looking for you for a long time."

Kamito started at the sound of a voice. Quickly turning around, he pointed the Vorpal Sword at the source of this voice, then gasped.

She was a young woman with beautiful red hair and eyes. Though she wore a gentle expression, she had a powerful presence. She was unarmed and carried no hostile intent, but Kamito still couldn't shake the feeling that she undoubtedly an enemy.

Barely reigning in an impulse to kill her, Kamito managed to force himself to speak, "who are you?"

"My name is Rubia Elstein, but you may know me better as the Calamity Queen." She replied.

Since both Kamito and Muir spent most of their time being trained by the Instructional School, neither of them knew that Rubia Elstein was a name hated by most of the continent. She was the former Flame Queen who abandoned her duty by stealing from the Fire Elemental Lord. This enraged the spirit king, who rained fire upon the continent in rage, hence her nickname: Calamity Queen.

Before either of them could reply, she stated, "While I'm sure you have many questions, let me first ask two things."

Not knowing what to say, Muir and Kamito both nodded.

"First of all, how do you two feel about helping me assassinate the five elemental lords?"

"""What!?""" the two girls (and sword) exclaimed in disbelief.

"Secondly, why are you, the reincarnation of the Demon King, a girl?"

"….What?"
