In the year 2020, on the fiftieth floor of a city's general administration building.

　　"It ends here."

　　The black-haired boy said in a heavy tone against the cold night wind, and listening to the wind, he could hear the rapid footsteps coming from the emergency corridor downstairs. Now those heavily armed soldiers, I'm afraid that in a few minutes will be able to come to the roof. The helicopter gunship had been shot down and the power to the building had been cut off, but that was as far as it went. This small team, only a dozen people, there is no way to fight against as many as hundreds of special forces, not to mention those surrounded by the building of those guys ... are thousands.

　　"To capture us? To kill us?"

　　The girl with short snow-white hair murmured nervously, and at the tips of her white fingers the water condensed into ice crystals, but then dispersed. For the girl who could manipulate the temperature, the cold she felt was definitely not just the night breeze from the roof, perhaps the despair from the heart was the real uncontrollable thing." I... We're worth something, aren't we? Aren't we?"

　　"As we go through the program, I think it's important for people to have that realization."

　　A dead silence fell on the roof as the people stared at each other. These people of different nationalities, different regions, different races, and even different ages. They were all standing in the same place because they possessed a certain quality - they possessed something that no one else did, and because of that, they were considered heretics, terrorists, or worthy of study. Many of them are feared, loathed, hidden or hunted, and this small group led by the dark-haired boy is a trusting companion built up through endless chases and escapes.

　　"Those guys put a bomb down there! It looks like they're going to blow up the building!"

　　A middle-aged man said with a pale face, he possessed the ability to sense the surrounding area, but now, this ability seemed to have no use other than correctly telling them that there was no way out.

　　"Those guys down there seem to be starting to retreat, so why don't we just ..."

　　"What a joke! You're going to rush downstairs and confront the army head on?"

　　"Useless."

　　The other girl twitched her nose slightly, then shook her head helplessly.

　　"Judging from the concentration of explosives they used, enough to blow up a third of the city, there's no way we can escape from this building in that short of time, and even if we do, we'll be caught in the blast ... results... ..."

　　"Completely screwed ...?"

　　A sense of despair like never before gripped the group, but at that moment, the dark-haired boy raised his head.

　　"I think I've got something."

　　"Eh?"

　　Perhaps because the words were so unrealistic, the crowd thought their ears were out of order for a moment, but the young man's gentle, calm voice came clearly into their ears.

　　"We don't have anyone who can defuse the bomb, and according to the analysis just now, even those soldiers will have to evacuate the nearby residents, although they will certainly be on guard to strictly prevent us from taking advantage of the chaos to escape, but I think that by the time the bomb explodes they will also be evacuated without having to worry about us escaping. After all, at that time even if we escape from this building, is also dead ... but very unfortunate."

　　The boy smiled bitterly.

　　"I think I can stop that thing. At the very least, I'll be able to delay it for a few minutes, and it's up to you to get out."

　　"Hey, you mean to say that ..."

　　The companions exchanged uneasy glances, knowing, of course, that the young man in front of them was unique among them, and that his abilities were just as special. But it meant that he had given up his own hope and left the chance of survival to the others. The roar of a helicopter was heard in the distance, and the snow-white lights shook the eyes of the crowd, but the other side had no intention of getting any closer. The wreckage of the helicopter, which was currently lying in the rubble with black smoke billowing out of it, was a good example, and it seemed that the helicopter was just watching them to make sure that these 'dangerous people' didn't run away at this moment. If they really made preparations to escape at this moment, compared to the other side will not hesitate to press the explosion button, as for the delay and explanation after the incident is also likely to be the natural gas unexplained explosion and so on, and then casually dismiss a few people.

　　It's because they're 'dangerous' that they're so reckless.

　　"It's about time."

　　The black-haired boy sighed, he slowly stood up, and then extended his right hand to the helicopter. The helicopter gunship, which could be easily overpowered by a tank, suddenly spun around and backed up like it was in a panic, looking as if it was terrified of the boy's right hand, which had nothing in it. The boy shrugged his shoulders helplessly and turned his head to look at his "companions".

　　"Well, it's time for you to make your choice. I think you realize that even if we escape this time, the hunt won't stop. If I want to live a normal life, then someone has to make a sacrifice. Yes, with full power, we could have stopped the explosion. But where does that leave us? Endless hunting, running away ... There's nothing we can do except that."

　　The boy said, looking once again at his companion.

　　"So, at least we might be free."

　　Even without an elevator, jumping off a 50-story building isn't that hard for these guys.

　　There are people with their feet on the walls, running downward in complete defiance of gravity.

　　Others fall as light as a feather, as if they weighed nothing at all.

　　Others appeared in a flash on a window ledge that could not have been connected, and moved down several floors the moment they disappeared.

　　In short, things that are impossible or impossible for human beings to do are easy or familiar to these people.

　　The black-haired boy stood alone in the silent hall, the blackness of the building without electricity, only the bombs tied to the pillars flashed bright red when they were counted down. As a matter of fact, if they had prepared such a powerful bomb, they might as well have prepared a missile. Thinking about it, the boy himself felt that it was a bit ridiculous to use such an exaggerated equipment just to deal with a dozen of them. Even if he died, he would be proud of himself in that world.

　　"Why didn't you leave?"

　　The teenager did not turn around, but asked somewhat dispiritedly, and from the darkness behind him, a figure slowly came out, until the bright moonlight shone through the glass window, revealing her figure.

　　It was a young girl with long, light blonde hair dressed in a slightly ornate nobleman's outfit.

　　Her gorgeous black dress, her doll-like white face, and her slender limbs. She was a beautiful girl in every way. But there was only one thing that made her different from others.

　　The young girl's left eye was golden yellow, like the color of dazzling gold. Her right eye was a beautiful aquamarine color, and she looked at the boy quietly, without saying anything. But the boy's original cold face smiled a little, seemed to understand what she meant.

　　"Really, want to help me? With your ability, you can really increase the success rate."

　　The young girl said nothing, but cocked her head slightly and nodded.

　　"Uh-huh? Will not be afraid? This ah ... to say that it is impossible not to be afraid."

　　The boy was talking to himself alone, but it sounded like he was answering a question from someone unseen.

　　"But what about ..."

　　Said the teenager, he sighed, his face became much heavier .

　　"Even if this continues, I don't think we'll be able to escape. And even if we do, our fate will not change."

　　"... Hmm? Cheer me up? Speaking of which, being in a bad mood at a time like this does affect your ability to perform."

　　The girl still didn't make a sound, not even opening her tiny pink lips, but the boy did seem to be answering her question. At that moment, the boy slowly turned around and stretched out a hand into the air. The girl stood behind him, back to back, with her hands clasped in front of her chest, like a nun praying.

　　The 50-story building trembled violently, and then in an instant, the energy that had wanted to burst out quickly seemed to be attracted by something. The building had already reached its peak. After a few minutes, the energy that should have been emitted erupted like a flood, and swept through the city in a frenzy. A huge explosion caught half the city in its path, and nothing was spared.

　　This is the end of the story of this world.
