"Huh? Where the hell is this?"

Standing in the middle of a wasteland is Nagumo Hajime, a young man who looked like he's only 17. He is wearing a white T-shirt covered by a black leather jacket, and he wears a black jeans. He has black hair and black eyes, while his appearance is above average, he had an atmosphere that attracts quite the attention making him attractive . He is currently confused and exasperated knowing what just happen.

"Did I just got transitioned to another world? Where am I?"

Looking around, all he could see are land devoid of life. He thinks for a second that this world is uninhabitable, but dismiss that idea considering he was able to breathe, and he could see that this place has an atmosphere for human to live.

So that he won't waste time immediately he take out the 'compass' that could search for anything in the multiverse, and the 'gate key' that could open a gateway to anywhere in the multiverse. He contemplated for a moment whether he would return home or scout the area to look for something interesting. But before he could make a decision he detected a presence filled with killing intent directed at him.

He leap back to safety and observe his assailant who was just dive bombed into the place where he had been and flew away to make another strike. The assailant looked like a giant bird covered by black feathers and red veins pulsated throughout his body.

"A demonic beast?"

The black bird seemed similar to the demonic beasts on 'Tortus'. The beast seems angry for missing it's prey from the surprise attack, and swoop down in an attempt to make another strike. Just as it approcaches within an arms reach it's head was decapitated by Hajime.

Using one of his skills, 'air claw', he manage to kill his enemy without effort. Weak, he thought as he scans the area for another attack but only met with silence. It seems that the beast was a bird of prey, which means that it only traveled alone. From the looks of it's body, indicates that it haven't eaten for a few days. Which also means that there is no prey within this wasteland.

And so Hajime thought that he would explore this world just for a few moments.

He immediately call his family about what happened and also store the corpse of the bird in his 'treasure warehouse', an artifact that could store anything within it. After he finished he immediately traveled through the wasteland in the two-wheeler he summoned from 'treasure warehouse' into the nearest population directed by the 'compass'. He also chages his attire to the one he used while he was during a battle. Which includes a long black overcoat.

—XXXXX—

After 45 minutes of traveling, he saw at the horizon what seems to be a giant wall about 50 meter in height made of what seems to be concrete. Before he could reach the wall, he place his two-wheeler in his 'treasure warehouse' and walk the rest of the way.

When he reaches the wall there seems to be a large closed gate with a couple of guards wearing military uniform that are armed with mechanized swords. From the looks of it the guard appears to be female.

(Is this a fantasy world, or a sci-fi world?)

Hajime thought as he approaches on of the guard. One of them noticed him and became wary at his presence.

"Halt! Who goes there? Show me your identification"

The guard commands demanding some identification. Which Hajime immediately answers.

"Nagumo Hajime, You don't need to know anything else"

"Very well then, you may proceed"

Hajime said that as he waves his right hand which was holding his smartphone, which also has a function to hypnotize people using 'soul magic'. He said his line just like a certain someone in the movie about wars in the stars. The guards, who didn't feel anything strange, comply and sends him inside the gate. Well that worked, thought Hajime with the feeling of triumph considering he used a technique from a movie as if it's normal. Such are the absurdity of the 'demon king'.

—XXXXX—

As soon as he's inside he noticed a few things. 1) all the military officials are females. 2) the level of technology is advanced but most of them are using swords. 3) most of the military officials are young. He predicts that most of them are 17-18 years old. He searches around stores to see if he could sell some items for money.

After 20 minutes he managed to sell some jewelries he had to a jeweler and gain a lot of money. The jewelries he sold were the ones he made using 'transmutation'. On earth after the incident Hajime creates a strore that sells jewelries and clothes to gain money.

While Hajime was sightseeing, a shockwave follow by a roar resounds through the neighborhood.

"GROOOAAAR!!!"

With that roar, a monster about 30 meter tall blasts away part of the wall connecting to the outside. What appeared was a 30 meter tall humanoid giant with black skin covered by red veins around his whole body, it also has a compound eye which helps increase it's point of view, and a big mouth with sharp teeth that can crush any objects it eats.

Immediately after it's appearance an alarm resound the entire neighborhood ordering the civilians to evacuate to a safety bunker. Hajime watches all this while erasing his presence so that no-one can see him. The evacuation proceeds smoothly as if this had happened before. The military officers held back the giant using their mechanized swords which can also be used as a range weapon. The swords shoot out energy blast at the giant in hope to at least damage it a little.

(Hmm? Are those powered by magic power?)

Hajime thought about their technology. Considering the advancement of technology, it's a wonder they uses magic for their power supply.

(Not that I can say anything considering I also uses magic power as my power supply)

Although the weapons has great fire power it did close to nothing against the giant. Judging from the reactions of the commander in-charge and the rest of the officers, something like this is not normal. And from lip-reading several people, Hajime figures out that the giant is called the 'Colossus', an S-grade threat level. Which means that the people here are doomed if they didn't have any counter measures.

Just as he thought this, a streak of light approaches the 'Colossus' and sends his body tumbling down. Hajime immediately looks for the source of the attack and spotted someone hovering in the sky. The source of the attack came from a female that looks to be 17 years old with waist-length blue hair and blue eyes. She is wearing a skin-tight suit with some armor plating. The female also appears to be holding a giant mechanized great sword about 2 meters in length. Although human eyes can't perceive it, Hajime's right artificial eye saw that the female's body is covered by a layer of protective magical energy, so she is not as defenseless as she appears to be.

( Hmm...interesting, the armor has the same ability as 'vajra', and it seems that it's always active )

'Vajra' is alse one of Hajime's skills that allows him to protect himself by covering his own body with a layer of magial energy.

While he thought that, as the female tries to charge another strike from her sword, the 'Colossus' return fire without giving her time to react. The 'Colossus' fired a large beam of red colored energy from it's compound eye into the female warrior. The female seems fine even though she was hit directly by the beam, return fire after regaining posture and position.

The fight continues for several minutes of them firing and dodging at each other. It seems that the girl was buying some time for either reinforcements or some kind of trump card. Because after a few more minutes, a volley of energy blasts are launched at the giant. It seems that reinforcements arrived. Hajime could see that an army came marching with their (what appears to be) tanks. With their combined assault the giant staggers and crouch down on the spot, giving the female warrior time to launch another attack. This time she operates her sword and the blade shines with a bright blue color. She then flew to the giant to strike a large blow. A soon as she approaches she thrusts her great sword into the giants head, piercing through it's skull.

The giant then staggers again and collapses on to ground. The battle ended with only some damage to the surrounding of the huge hole in tha wall. The girl immediately lands and pants because of exhaustion. Her armor dematerialized revealing the girl's body in her skin-tight bodysuit.

( it seems like it's the kind that consumes energy as long as it's activated and dematerialized after it's energy is exhausted )

Hajime thought this as he observed the battle, and he immediately summon his weapon, 'schlagen', from his 'treasure warehouse', because the battle is not over.

—XXXXX—

Ciel Grandania, a warrior of eden's valkyrie from the Grandania family. She is 17 years old and has already been promoted into a valkyrie from einherjar at the age of 16. Valkyries are elite warriors handling the threat of tyrannal beasts with threat level ranging from C-grade to SSS-grade. While einherjars are warriors or soldiers handling threat levels at the range of F-grade to D-grade.

After years of training Ciel managed to reach S-rank at the age of 17, and her first assignment is to subjugate the 'Colossus' that appeared in the eastern gate.

A few minutes after the battle, the V-drive immediately loses power and dematerialized her armor. In this state, although a valkyrie can still defend herself, she is at her most vulnerable position.

( it's a good thing I finished it off before my power run out )

As soon as she thought this, the giant thought to be dead rises back up slowly. Although a part of it's head is destroyed, it still manages to somewhat move albeit slowly. It also began to ever so slowly regenerating it's wound. Ciel interally curses at the giant.

( damn! I missed the core! )

While some tyrannal beasts die the moment their heads are separated, high grade beasts will only die by having their core destroyed. As Ciel thought that she will die because of her carelessness, a flash of light followed by a roar and sparks of lightning resounded the entire area.

The flash of light was Hajime using 'schlagen', an anti-material rifle that are 10 times more powerful than a normal anti-material rifle that the military had, combined with his skill 'lightning clad' to super charge the acceleration of the bullet using electromagnet, turning it into a railgun, further increasing it's destructive powers. The railgun was aimed at the head of the rising 'Colossus', more specifically the core. Using his scope and aiming skills that are considered godly, he pierced the core shattering it while scorching the giants flesh. Fortunately he aimed his rifle upwards because of the position of the head, and didn't cause any damage to the surrounding area.

Even though Hajime always thought that saving people was troublesome, he still had some common sense to save someone from a disaster. Although immediately after he shot his rifle, he put away 'schlagen' into his 'treasure warehouse' and hid his presence, disappearing from the area before people notices what happened.

—XXXXX—

After a few moments of silence in the area, everyone was dumbfounded at just what happened. Ciel was feeling confusion and relief at what just happened. She looks around to see if she can identify her savior, but didn't spot anything. Usually people would immediately take credit and boast about saving someone's life, or at least approach the victim to tend to their safety. She had always repayed the gratitude of the one that helped her, but this individual seem to keen on hiding his achievement. She was also curious at what weapon that individual used to kill the 'Colossus'. Even though it's already weakened it is still not an easy feat to kill it in one shot with pinpoint accuracy through the core.

However Ciel didn't have much time to be idle since she has to report her mission.

Somewhere in the vault with a very high security, in the dark room with no light, a single entity has awoken.

"The Demon King has arrived"
