Alfonso took long deep breaths, recovering quickly from his run, his eyes still closed.
He sensed everything up to 10 meters around him. The way he perceived the world was similar to Daredevil. He opened his eyes, blinking a few times until his eyes got used to the light. Alfonso looked at all the junk in front of him but sensed at the same time the things behind him, nothing could escape his senses 10 meters around him.
His gaze became sharp as he controlled his ability, he was slowly but steadily increasing his output. There was no change in the surroundings at the beginning but a sound broke the silence...
The rubbles on the ground were the first to tremble, weak first, then harder...
Then it was the junk around him which began to produce loud metallic sounds, the piles of old industrial waste began to shake violently under his increasing power output.
A loud rumble echoed through the huge hall and Alfonso felt the ground underneath him shake. Veins popped out from his forehead as his breathing grew heavier...
Alfonso directed his gaze towards a metal pipe near him, stretching out his hand in its direction, making a squeezing motion like Darth Vader. The pipe which was already shaking started to shake even more violently.
His eyes become bloodshot while veins popped out on his hand as he focused his ability on the pipe. The pipe produced a loud sound as it gave in to his power, deforming until it cracked, slowly breaking apart...
Alfonso clenched his hand to a fist, making the air around it tremble, before punching into the air.
A loud sound echoed through the area as he watched a pile of junk being blasted away a few meters by a small shockwave...
He dropped his hand, breathing out as he relaxed. The ground stopped shaking, letting the surroundings return to its initial silence after all the junk stopped falling down.
'It's really like a muscle, the more you use it the stronger it gets...' Thought Alfonso as he smiled in a lunatic way that only men of culture could understand.
He first became aware that there was something strange about himself when he was 6 years old. It was so weak in the beginning that he thought that he was imagining things. He only grew suspicious about his ability after entering school and learning about the fact that some humans began to awaken kinetic abilities after the Abyss Terror happened.
Scientists came to an agreement that monsters weren't the only thing that came to Earth through the Abyss Gates. They theorized that some kind of energy seeped out from the Abyss into Earth through the Abyss Gates which caused some humans to awaken kinetic abilities. They had no way to detect that energy but it was their only and most likely explanation for the growing trend of humans awakening kinetic abilities. They found abnormalities inside the brains of deceased humans who had abilities.
The most common kinetic ability which humans awakened were variants of Telekinesis where those people could manipulate certain objects. But even humans powered with kinetic abilities didn't stand a chance against the monsters from the Abyss...
It took him some time to grasp some control over his ability and figure out what it did. Alfonso thought that it was some kind of sensing ability as he could only sense things less than one meter around him at that time. He consoled himself at that time that any ability was better than no one and that such a sensing ability would become crucial for his survival later as he had already decided at that time that he would become a Slayer.
He kept it secret that he awakened an ability, slowly gathering as much information as possible about them from his teachers. It was that way that he found out that kinetic abilities were like invisible muscles, the more you use it the stronger it becomes. It exhausted him using it, making him more hungry than usual. He only had enough food to not starve as he was an orphan, that's why he began to do 'junk jobs' for a few bucks to feed himself well enough...
It was only when he was 10 years old that he got on the right track to figure out what his ability really was. His constant use of his ability paid off as he could within 10 years sense everything 3 meters around him. Alfonso always tried to do something else with his ability, and some day he managed to make a cup shake. It surprised him, making him think that it was telekinesis or a weaker variation of it after all but he could do nothing else than making things shake a bit...
'Seismokinesis...I spent the past years mastering Seismic Sense and Vibration Sense as support to eliminate any blind spots. Shockwave Manipulation and Tremor Manipulation are my priority now but they are still far too weak, especially Tremor Manipulation...' Thought Alfonso while recalling how excited he was when he figured it out 6 years ago.
Alfonso was so glad that he once wasted a year in his past life. He spent a whole year after finishing school as an otaku, binge watching one anime after another until turning towards manga and then even to light novels. It was like a slippery slope at that time, only changing after his mother brought him to his senses, thus he decided to join the German army and turn himself into a man...
'The potential of Seismokinesis is theoretical over the top, as one could become a second Whitebeard but reality is harsh...I have drastically improved my ability over the past years as I knew what to focus on but it's still not growing fast enough for me...I hope that it will change tomorrow...' Thought Alfonso as he began his run back to the orphanage.
There were 4 known ways to improve a kinetic ability. First was the most common way, kinetic abilities would slowly become stronger with time passing. Second, to make it stronger through constant use. These were the two most common ways to improve kinetic abilities but it wasn't enough, even a transmigrated person like Alfonso with much more experience than most people only managed to improve so much. He would die for sure if he faced a monster from the Abyss, so would others. That's why many people and almost every person who awakened a kinetic ability decided to become a Slayer.
The Abyss Slayer Union was the number one organisation spread through various regions that were once Germany, Austria, Netherlands and Belgium. They had branches in many major cities and controlled the method on how to turn normal humans into Slayers. They were really secretive about it and the only thing that the masses knew was that it was called body modification treatment...
The fourth way was to bond with an Elemental but there didn't exist any of them in Dortmund as far he knew. That left people only with one choice, to agree to body modification treatment that the Abyss Slayer Union tightly controlled...
Alfonso greeted the patron of the orphanage and the others when he returned, changing clothes before heading out again towards his usual junk job...It would be his last time cleaning that shithole...
