Ryuichi P.O.V
If I was completely honest, one of the most valuable abilities I could inherit from Son Goku, at least from a strategic point of view, was ki detection, but why?
I mean, with things like the ability to fly, teleportation, Kamehameha, Genkidama, or even ultra instinct, how could something as simple as detecting life energy or ki help me?
Well, that's because of an important rule that was seen a lot throughout Dragon Ball, not to underestimate the power of an opponent or overestimate your own taking into account only the appearance.
Nappa looked more imposing than Vegeta, the third frezzer form was much creepier than the fourth, the dai ni dankai form was much better in combat than the dai san dankai, majin buu and kid buu were terrifying enemies despite their cartoonish and childish appearances, and that without counting to beings like the great priest or Zen'ō.
Plus other benefits like making surprise attacks and spies mostly ineffective unless they were better at ki control than whoever was trying to find them, or the fact that you could tell who was "good" or "evil" by the feel of their ki.
It was because of all this that one of the things that I practiced the most every day was the ability to sense ki, unfortunately, it seemed that it was not as good as a Shonnen MC or a random reincarnated, because the most I could do until now was feel and look for the ki of a specific person whose ki he had already sensed.
If I were to put it into words, it would be like if I had given a candle to someone and then they walked away, walking in a dark wasteland, I could still "see" the candlelight, but only because I had recently sensed their ki, while another person might be a few streets away from me and I wouldn't be able to sense their ki if they hadn't recently been in my "field of vision", so at this moment the only ki I could feel and identify was that of my teacher, Kirisu Mafuyu.
And that was also the reason why I was moving as quickly as possible in her direction.
After we separated I got a little distracted while listening to music and jogging, but when I got to the park that I had made my training place and got ready to start, I decided to try to feel her ki one more time while I exercised just to see if I could still do it.
And I did it, but the direction and distance in which I felt it was what caught my attention, based on my current position, I would say that the place where we separated was to the east, quite close to her place, but at this moment I could feel her ki in the northeast, much further away from where her house was.
And the worst of all was the presence that was close to her, which I could feel not thanks to my poor abilities, but to the fact that it was close to a ki that I was already feeling, because the size of that ki was several times bigger than that of any ordinary human, and that the feeling that that presence radiated was as incredibly unpleasant as it was malicious.
This rang several alarm bells in my head, so I left my backpack, filled with the things I used to train, and ran around the city while using my ki to strengthen my body and increase my speed.
I wasn't going to lie, the minutes it took me to reach the presence of my teacher and whoever was close to her were quite stressful, I knew that this world was not a normal one, but I didn't know to what extent, so I wanted to find my teacher before some bald, noseless idiot threw a hocus-pocus and transformed her into a cat, a mouse, or who knows what else.
The minutes passed, and the more I ran, I realized where this being was taking my teacher, to the part where there were many abandoned warehouses, which, according to my knowledge of comics and manga, could not mean anything good.
When I finally managed to find the warehouse where they were and entered through the back as quietly as possible, avoiding some half-open boxes full of dust or some half-broken scaffolding, I could see my teacher, but as I did so I could feel cold sweat dripping down my neck.
She was right in the middle of the warehouse, hanging just over a couple of meters from the ground, her arms and legs wrapped in spider web while her eyes were open and her normally already neutral expression had transformed into an inert mask with open and empty eyes, making her look more like a doll than a person.
And in front of her was a woman, no, calling that thing a woman would not be correct, from the belly up it resembled a woman, but the lower part of her body was that of a spider with shiny black skin, with eight thin legs that raised her until she was face to face with my teacher.
"Very well, my little cutie." The monster said in an unpleasantly sweet and sarcastic voice before an unpleasantly long and slightly hairy tongue came out of her mouth and licked my teacher's cheek.
"I thought I could handle the hunger a little longer, but playing with you will only make it take longer for me to find my next meal, so let's put aside all the foreplay and..." She spoke before opening her jaw to the point that it seemed to dislocate as her fangs grew, horrifying me until I almost turned around and fled the scene. "Let's get straight to the fun part." She finished saying, but this time her voice was distorted as she brought her jaw closer to the face of her victim.
Clank*
Until her head moved to the side as a result of a metal bar that hit her directly in the temple.
"Eh?" Was all she said as the sound of the bar falling echoed in the room, her expression showed confusion when her hand moved to touch her head, and when she saw it, she noticed the trail of blood.
She slowly turned her gaze, and when her eyes finally met mine I felt like I had jumped out of a plane without a parachute.
######
Third Person P.O.V
Even with cold sweat pouring down his back, Ryuichi clenched the metal bar in his other hand and threw it at the monster, but before the object was halfway there, the spider woman screamed, a sound that was somewhere between a roar and a screech while she ran towards to who had interrupted his meal.
Ryuichi's eyes filled with alarm as he turned around and began to run, grabbing two new metal bars from the several that were lying on the ground.
The creature advanced without caring about anything that was in its path, half-broken shelves, wood boxes, and counters filled with dust were destroyed or sent flying in its wake as she ran at full speed.
And when she saw Ryuichi near an exit door, she jumped with all her strength, landing on the wall where the door was, and in front of Ryuichi.
The monster woman moved her claws intending to slash the intruder's face and neck, but before she touched him, Ryuichi took a step back, narrowly dodging the attack and swinging one of his arms using the metal bar he was holding as an improvised club.
The movement seemed to be correct when the woman's face was moved to the side as the object sank into her cheek, while Ryuichi took advantage of the seconds of daze to take a few steps back.
"BASTARD!" She screamed as she tasted her blood in her mouth, spitting out saliva and blood with her scream.
Her jaw dropped open again as she leaped towards Ryuichi with the intention of either biting him, injecting him with her venom, or tearing off a piece of his flesh.
But once again, Ryuichi took advantage of the fact that he had an object he could throw, throwing one of the metal bars directly at the woman's face, hitting her in the nose, and unbalancing her enough that she fell to the ground on her back while the boy turned around and ran again.
Fear
Fear
I'M AFRAID
His entire body was trembling, and moving was more difficult than it should have been, but even with his heart beating so fast that it could burst out of his chest due to fear, Ryuichi continued to move as best and fastest as he could in the direction of his teacher while holding the remaining metal bar tightly.
And when he saw her appear in his field of vision, the noise behind him made him turn his head as he prepared to throw the bar again, but before he did, a bunch of thread wrapped around his hand, leaving the bar stuck to his hand and without the possibility of throwing it.
But worst of all, her strings were going straight into the palm of the monster woman, who pulled on them, causing Ryuichi to be pulled straight towards her as she opened her fang-filled mouth.
Thinking quickly and finding no other option, Ryuichi held the free end of the metal bar with his other hand and placed it in front of him shortly before the woman closed her mouth, biting down on the metal bar instead of Ryuichi's head.
The metal screamed as the creature's teeth sank into it, the woman moved her jaw trying to destroy the object and reach her target, and from the sound the bar emitted, it was a matter of a few more seconds before it broke.
Unnoticeable to the creature, a thin, semi-transparent layer covered Ryuichi's body similar to steam, and when his legs moved, both feet slammed into the monstrous woman's chest, cutting off her breath, feeling like something he had hit gave way and sank into her chest.
Using this momentum and the weakening strength of the monster's grip, Ryuichi was able to walk away from her unharmed.
"Ugr." Or at least that's how it would be if it weren't for the cut on his right arm that went from his shoulder to the middle of his bicep as a result of the woman's claws that had managed to hurt him while he was walking away from her.
The burning of his wound and the warmth of the blood running down his arm dimmed due to the adrenaline flooding through his veins, but knowing that this wouldn't last long, Ryuichi got up as fast as he could and managed to reach his teacher.
He pulled as hard as he could on the threads that held her in place while behind him, he heard the spider woman gasp, trying to catch her breath as she cursed him, but no matter how hard he pulled, he couldn't break the bonds.
In his mind, he found a way to remove them all in one movement, and although it would be possible for him to do so, he did not know how much pressure it would put on his body.
But when the sound emitted by the woman's legs standing up, similar to that of heels sounded behind him, he knew he had no choice.
"AHHHHHHH!" While holding the threads that covered Mafuyu's legs, Ryuichi's scream resounded at full power as his body was covered by a semi-transparent white aura, differently than before, this time it was completely visible to anyone who saw the teenager.
The threads that covered both the hands and the teacher's legs were destroyed and swept away like fluff carried by the wind, and a second later, the aura disappeared.
Expulsion of ki through the manifestation of an aura, something that any ki user in Dragon Ball could do, both to reinforce their abilities, as a display of an enormous concentration of ki for an attack, or in this case, as a way to destroy any restraints clinging to the person's body.
But with such limited energy reserves as Ryuichi's that expulsion of energy took away quite a considerable portion of his energy as well as putting a certain amount of pressure on his body.
And the proof of that was the sweat dripping down the boy's face along with the fact that he barely managed to catch the falling woman before her body hit the ground.
Slowly but clearly, the woman's eyes opened, her trance canceled as Ryuichi's ki surrounded her to reach the threads, and the first thing she saw was who was holding her.
"Kaname…kun?" She said confused.
"Sensei, we must-!" Was all Ryuichi managed to say when a figure hit him with the power of a cannonball, sending both teacher and student flying, only for Kirisu to roll on the ground for a few meters while Ryuichi skidded like a car out of control until his back hit a concrete column.
"GAHH!" A muffled scream and a desperate gasp were all that came out of Ryuichi's mouth as he writhed in a fetal position on the floor, trying to breathe once more as his previously injured arm bled even more as a new set of 4 diagonal cuts were left on his limb.
At his side, the metal bar that he was holding fell cut into several pieces as a result of trying to block the spider woman's claws, being the only reason why his arm had not been completely severed.
"INSOLENT WORM! I'm going to make you beg for me to kill you!" The woman screamed with bloodshot eyes and some saliva coming out of her fang-filled mouth while she was still breathing heavily.
While all this was happening, Kirisu Mafuyu found herself in a state of panic, she didn't understand what was happening, the last thing she remembered was leaving the convenience store where she had bought some things, and now she had just received a blow that left her entire body sore, and yet, this wasn't the worst.
A few meters away from her, lying on the ground in a red puddle that was slowly growing as he gasped for breath, was the student with whom, at least from her perspective, she had been walking and talking just under 5 minutes ago.
And almost a dozen meters away was what could only be described as a monster straight out of a horror movie.
Kirisu felt her entire body tremble just listening to the monster's voice, and although everything inside her kept screaming at her to get up and run in the opposite direction, she crawled with trembling legs and with a slight limp until she reached where her student was lying.
"K-kaname-kun." Was all she could say when she saw the pained expression on his face and his red-stained clothes.
And when their eyes met, for a moment, Ryuichi's eyes regained some clarity before his gaze moved from his teacher to what was behind her, only for his expression to turn into one of alarm.
Stretching out his uninjured arm, he grabbed her arm and pulled her along, barely preventing the woman's claws from slicing her neck.
They both rolled several meters in an attempt to get away, but the pain in Ryuichi's injured arm prevented them from continuing to walk away that way, so after a few meters Ryuichi sat down while his uninjured arm still held his teacher.
Staring at them with hatred as gasps came out of her mouth, the spider woman growled, one of her hands held her chest as if she were trying to dull some pain, and ugly bruises were visible on her cheek and nose.
"Sensei… can you… run?" Ryuichi spoke between labored breaths while his face had turned a little pale.
"M-my legs d-don't respond well." She said, fear clearly seeping into her voice.
"I... I won't last conscious for too long." He said before giving his bleeding arm a quick worried glance as he gritted his teeth in pain and felt his eyelids growing heavier. "When I tell you, please cover your eyes, I need you to be able to run after that, or neither of us will get out of here." He admitted, and although he tried to hide it, it was clear that he was also incredibly scared.
With that said Ryuichi stood up with his teacher behind him while the spider woman slowly walked until she was less than 3 meters from both of them, well aware that the boy in front of her was not normal, if the bruises on her face and the broken rib she had were any proof.
She knew that it was only a matter of one more blow for the boy in front of her to fall, but that was why she didn't rush towards him blindly, because in their desperation, everyone could do stupid and reckless things, and she didn't want to know what kind of damage or injury could this human do to her in his final moments if she was too reckless.
Standing without taking their eyes off each other, the boy and the monstrous woman waited for the other to make their move.
'Come on, attack me while looking directly at my face, don't you dare take your eyes off me.' Ryuichi thought as he flexed the muscles of her injured arm a little, opening and closing his hand to confirm that he could still move it.
At that moment, interrupting the staring contest, something hit the doors at the main entrance of the warehouse, flinging them open, causing both the woman and Ryuichi to turn their heads to see what appeared to be a tentacle of water coming from outside the warehouse.
And although this surprised him, Ryuichi knew that this would be his only chance, because if somehow what was coming was like the woman in front of him, he definitely had to escape right now, or he would be 100% dead.
"NOW SENSEI!" He shouted, drawing the attention of Mafuyu, who had also directed her gaze to the entrance.
Without waiting for another second and noticing how his voice had just caught the monster's attention once again, Ryuichi moved his open palms until they were in front of his face as he looked directly into the spider woman's eyes and shouted.
"TAIYOKEEEEN!"
X-X-X-X
Well, as promised, here is the chapter, and it serves not only as the first direct approach to the supernatural world, but also to dictate what Ryuichi will think about the supernatural world in the future and what his current power level is, a very low one as anyone could expect (he will not become the strongest after training only a couple of weeks), but don't worry if this isn't clear enough, the next few chapters will make that point completely clear.
It took me a little longer than I thought to write the "fight" part, although this is actually more like Ryuichi doing everything he can to not be killed, he is inexperienced and was very scared, so his movements were very clumsy, I hope I have captured it well enough.
In addition, I would also like to ask, what do you prefer that I use for the names of the techniques, the English translation or the Japanese name?
Personally, I prefer Japanese names like Genkidama and Taiyoken instead of Spirit Bomb, or Solar Flare, (except with ultra instinct, because that sounds better than migatte no gokui), but I would like to hear what you think.
Remember that if you like this story, you can leave a comment, review, or a power stone, that will inspire me to write more, see you in the next chapter.
