Guys, sorry for the new writing style, I'll bring you more chapters and other different works in the coming days.
Diego: (If I want to control the Reverse Damn Technique, I need to understand it better... and for that, I have to see it in action.)
I walked away from Saji without answering anything else. It was not the time to talk to him anymore. I needed to train.
When I finished the classes, I went straight home.
I sat down on the floor and closed my eyes. I activated all Six Eyes and observed my own body, focusing on my cursed energy.
Diego: (To use the Reverse Damn Technique, I have to turn negative energy into positive. It's like a collision of two opposite charges... but it's not that simple.)
I could clearly see how the cursed energy was flowing through my body. It was dense, dark, but when I tried to reverse it... the flow became unstable and collapsed.
Diego: (Tsk... I need to compare this to something. If only he could see the Reverse Damn Technique in action, he would understand better how to stabilize it.)
I gritted my teeth and concentrated. I had to try again.
I raised a hand and forced the cursed energy to collide on my palm. I tried to control the reaction... but at the last moment, the flow got out of control and the energy dissipated.
Diego: (Shit... I failed again.)
I took a deep breath. I couldn't despair.
I decided to analyze something else. I focused my Six Eyes on my entire body, but this time observing my cursed energy control in general.
Diego: (If I want to improve my control, I first have to understand how the cursed energy flows inside me. Every cursed sorcerer has a unique flow... mine is not polished yet.)
I noticed that my cursed energy had certain points where it flowed faster and others where it got blocked.
Diego: (These blocks... are due to lack of experience. If I can get my energy flowing continuously, I'll be able to use the Reverse Damn Technique better... and my own power in general.)
I adjusted my breathing and tried to smooth the flow of energy inside me. Gradually, I felt how the energy was distributed more evenly.
Diego: (This is... better. It's not perfect, but at least now I have a base to keep training.)
I stood up. I couldn't stay training all day. I had already made some progress, but I needed real experience.
Diego: (If I want to improve, I have to keep fighting. It's already dark... it's the best time to hunt demons or fallen angels.)
I put on my jacket and left the house.
I had a bad feeling about it. Something was going to happen tonight.
And I wasn't wrong.
I walked through the dark streets of the city, my eyes scanning everything around me. With the **Six Eyes** active, I could see the energy flowing in every person, every being. But I wasn't looking for humans.
Diego: (Come on... there has to be some damn demon or fallen angel nearby.)**
My body was still hurting from the last fight, but I didn't have time to rest. If I wanted to become stronger, I had to train in real combat.
After almost an hour of walking, I finally felt it.
In a narrow alley, a dark presence.
I calmly approached and saw him.
A **demon**, about two meters tall, grayish skin and long claws. His red eyes glowed in the darkness, and in his hand he had what appeared to be... a human arm.
**Diego: (Tsk... it seems he was late to save someone.)**
The demon slowly turned around and looked at me, showing a sharp-toothed smile.
"Hmm... human, but with something different—" he said in a deep, raspy voice. Are you one of those magicians in the church?
I spat on the floor.
- I have nothing to do with the church, but I'm going to kill you.
The demon laughed, his breath reeking of blood.
- Hahahaha... kill me? Boy, you're fucked.
I didn't answer.
In an instant, ** my cursed energy exploded**, covering my entire body.
**Diego: (I'll do better this time. I'm going to use my damn energy more efficiently.)**
The demon growled and jumped towards me with a brutal speed.
But this time, I saw everything.
His movements were clumsy compared to what my eyes caught. I read his attack before he even did it.
Diego: (My control improved, there are not so many blockages anymore... my energy flows better.)
I leaned to the side and avoided his claw, feeling the air cutting my cheek.
I extended my hand towards him and the blue energy burst out.
- Blue!
An invisible force pulled him with brutality. His body was thrown towards me uncontrollably.
At the exact moment, I closed my fist covered with cursed energy and Infinity and put a punch straight to his jaw.
- GAAARGH!! - The demon spat blood as his jaw dislocated from the impact.
I didn't give him time to react.
I turned Infinity off for a split second to save power and turned it back on just before it hit back.
The demon tried to scratch me, but his claw stopped inches from my face.
- What the fuck...?
I smiled.
- Infinity, asshole.
Before I could react, I raised my hand and threw another Blue, harder this time.
The demon exploded in blood, his body shattering against the wall by the force of the attack.
I took a deep breath, my hands shaking a little.
Diego: (I'm getting better. But it's still not enough.)
I observed the remains of the demon scattered along the wall of the alley. Dark blood and pieces of flesh slowly dripped to the ground.
Diego: (I keep spending too much energy... although my control has improved, I can't trust myself.)
I shook my hand, scattering the last traces of my cursed energy. My body hurt, but it was a bearable pain. I looked up at the sky.
Four days.
Four days until Issei Hyoudou died at the hands of Raynare.
My plan wasn't complete yet, but I knew one thing: I needed to get stronger before trying to take the Boosted Gear.
I turned to leave the alley, but then I felt another presence approaching .
He wasn't a demon.
Not a fallen angel either.
- Who's there? - I asked quietly, getting ready to fight if necessary.
From the shadows, a female figure calmly walked out.
He had the uniform of the **Kuoh Academy**, black hair tied in a ponytail and an imposing aura.
My eyes narrowed as I recognized her.
- **Akeno Himejima.**
She smiled with that playful air she always had.
- Well, well... what a surprise to see you here at this hour, Diego-kun.
I didn't let my guard down. Knew what Akeno really was . A nephilim, a hybrid of human and fallen angel. And not just any fallen angel, but the daughter of Barakiel, a faction leader.
—I was just taking a walk—" I replied, keeping my tone neutral.
Akeno looked at the mess he had left in the alley.
- A walk, you say? — i laugh softly-. I didn't know that walks now included blowing up demons.
Diego: (Shit, this is not good. If Akeno is here, it means that Rías already has his eye on me.)
Akeno walked slowly towards me, still smiling.
- You're an interesting guy, Diego-kun. I feel a rather peculiar energy in you... something that is not just magic.
I didn't answer.
She tilted her head a little, evaluating me with those violet eyes that seemed to scan me completely.
Are you hunting demons too?
My lips curled into a faint smile.
- Something like that.
Akeno laughed again and moved a little closer.
- Hmm... I wonder what Rías will think about this. I'm sure he'll find you even more interesting.
Diego: (Tsk, I don't want to attract Rías' attention yet. But I also can't act like I'm just a human, not anymore.)
I looked up and looked her straight in the eyes.
- Tell Rías to stay out of my business.
Akeno opened her eyes a little, surprised by my answer, but her smile quickly returned.
- Fufu~ how brave. I like it.
She turned around and started walking back into the darkness of the alley.
- So, I'll see you at school tomorrow, Diego-kun. May you have sweet dreams.
And with those words, disappeared into the shadows.
I was silent for a few seconds before letting out a sigh.
- This is getting interesting.
Diego stood watching the place where Akeno had disappeared, his mind processing every detail of the interaction.
Diego: (I have to hurry. If Rías is already interested in me, it means that I don't have much time before they try to involve me in their affairs. I need to master the reverse damn energy as soon as possible.)
With that thought, he returned to his apartment. His body was still sore, but he knew he couldn't afford to rest.
Diego sat on the floor of his small apartment, activating the Six Eyes. The heightened perception allowed him to observe every flow of cursed energy inside his body with almost atomic precision.
Diego: (The inverse cursed energy... is like multiplying two negative forces to create something positive. But the problem is to stabilize it. If I fail, the energy collapses and is useless.)
He closed his eyes and began to focus on his energy flow. He could feel the negative energy moving chaotically inside him, like a turbulent river.
Diego: (I need to calm the flow first. If I can't control it, I will never be able to generate positive energy.)
He took a deep breath and began to direct his cursed energy towards a specific point on his abdomen, trying to stabilize it. However, every time I tried to multiply it to create positive energy, it collapsed and dispersed.
Diego: (Shit! This is harder than I thought.)
The sweat was starting to run down his forehead, but it didn't stop. He activated the Six Eyes again, observing in detail how the energy got out of control every time he tried to reverse it.
Diego: (There's the problem... I'm applying too much force at the beginning. I need to be more precise.)
With that new perspective, he began to adjust the energy flow, applying only the minimum amount needed to start the reversal process. Little by little, he felt how a small spark of positive energy began to form inside him.
Diego: (That's it! Now I just have to keep it stable.)
The process was slow and exhausting, but after several hours he finally managed to generate enough positive energy to heal a small wound on his arm.
Diego: (It's not much, but it's a start. If I keep practicing, I will eventually be able to use this technique in combat.)
After resting briefly, Diego decided to focus on improving his overall control over the cursed energy. He knew that if he wanted to take on stronger enemies or even take Issei's Boosted Gear without killing him, he would need a stranglehold on his energy flow.
He activated the Six Eyes again and began to analyze every corner of his body where the cursed energy flowed. He observed how it accumulated at certain points and how it dispersed at others.
Diego: (My flow still has too many inconsistencies... There are power leaks in several parts. I need to correct that.)
He began to perform specific exercises to redirect energy to the areas where he was most efficient. Every movement was calculated in detail thanks to the Six Eyes, which allowed him to detect even the slightest imperfections in his control.
After several hours of intense practice, he felt a noticeable improvement in the fluidity of his cursed energy. Now I could channel it more accurately and without wasting as much as before.
Diego: (This should be enough for now... But I'm still far from the necessary level to face someone like Rías or Akeno if they decide to attack me.)
While resting on the sofa, Diego began to plan his next moves. He knew that he had little time before Reynare killed Issei and triggered the main events of the anime.
Diego: (If I want to take the Boosted Gear without killing it, I need to perfect my reverse damn technique and my energy control before that day.)
He looked out the window at the city illuminated by the night lights. His mind was full of possibilities and strategies for what would come next.
Diego: (I also need to find more demons or fallen angels to practice my skills in real combat... But I have to be careful. I can't get too much attention yet.)
With that thought, he closed his eyes and let his body rest for a few hours before continuing with his training the next day.
Time lapse: next day
When he arrived at school the next day, Diego noticed that Issei was still acting as usual: talking to his friends about kinky things and not worrying about what was to come.
Diego: (It's amazing how ignorant he can be... But I guess that's what makes him so easy to manipulate.)
During the classes, Diego discreetly activated the Six Eyes to observe the energy flow of the Boosted Gear inside Issei's body again.
Diego: (There it is... The connection between him and the Boosted Gear is not as strong as I thought. With a little more practice I could break it without damaging it.)
At that moment he decided something important: before trying to take the Boosted Gear, he would look for a direct confrontation with another fallen angel or demon to test his new abilities.
Diego left the school with his backpack hanging over one shoulder, his thoughts revolving around what he had observed during classes. The Boosted Gear inside Issei was more accessible than I had imagined, but I knew I couldn't rush it.
Diego: (If I fail while trying to take it, I could kill him or even destroy the artifact. I need to be completely sure before I do anything.)
While walking through the streets, he activated the Six Eyes to observe around him. The cursed energy allowed him to perceive things that others could not, and he was looking for something in particular: a new prey.
After almost an hour of walking, he felt a presence
A fallen angel was standing in front of a human, clearly manipulating him for some twisted purpose. Diego frowned.
Diego: (I can't let this go. It's a good opportunity to test what I've learned.)
He approached slowly, making sure not to attract attention until he was close enough. When he was a few meters away, he spoke in a firm voice:
- Hey, why don't you leave the guy alone and face someone who can fight?
The fallen angel turned his head towards him, showing a mocking smile.
- And who are you? Another human idiot playing the hero?
Diego smiled sideways as he let his cursed energy start flowing around his body.
- Something like that... but this "idiot" is going to kick your ass.
The fallen angel laughed and spread its black wings before darting towards Diego with speed. But this time, Diego was ready.
With the Six Eyes active, Diego could read every movement of the fallen angel before it happened. He moved to the side to dodge the first attack and raised his right hand while channeling his cursed energy.
- Blue! - he shouted, releasing a shockwave that pulled the fallen angel towards him with brutal force.
The impact was enough to unbalance him, but not to defeat him. The fallen angel quickly recovered and counterattacked with a dark beam aimed at Diego's chest.
Diego barely managed to activate **Infinity** in time to stop the attack, but he felt the immediate wear and tear on his cursed energy.
Diego: (I have to be more efficient... I can't waste energy like before.)
He deactivated Infinity for an instant and lunged forward, dodging another attack from the fallen angel while charging a punch covered in cursed energy into his right fist.
The impact was direct to the fallen angel's abdomen, making him retreat several meters while spitting black blood.
"Damn..." the fallen angel growled as he tried to get up. What the hell are you?
Diego wiped the sweat from his forehead and smiled wearily.
- I'm just someone who is tired of seeing how you guys do what you want with the weak.
The fallen angel tried to attack again, but this time Diego stopped him before he could move. He stretched out both hands and channeled all the cursed energy he could muster in a final instant:
- Blue! - he shouted again, this time with more force than before. The shock wave shattered the fallen angel into pieces, leaving only black spots on the ground where he had been standing.
Diego leaned against a nearby wall as he caught his breath. His body was shaking from the effort, but he knew that he had improved significantly since his last confrontation.
Diego: (My control is much better now... But I still spend too much energy on each attack.)
He activated the Six Eyes once more to observe his own energetic flow. He could clearly see where the leaks and weak points in his control were, something he would have to correct if he wanted to be more efficient in future fights.
Diego: (This is just the beginning... If I want to face Reynare or even someone like Rías or Akeno one day, I need to be much stronger.)
With that thought in mind, he started walking back to his apartment to continue training
When he got home, Diego dropped down on the floor and closed his eyes for a moment before refocusing on his reverse cursed energy training. I knew that I didn't have much time before the main events of the anime started to unfold, and I had to be ready for anything.
Diego: (Issei is still an idiot with no idea what's going on... But soon everything will change.)
With that thought, he plunged back into his intensive training, determined to perfect every aspect of his skills before the decisive day
