Issei's Darkness- A Highschool DxD Fanfiction

(These events transpire six months after Loki's Curse)

Chapter 1- A Broken Mind

Issei was staring at the ceiling in his room as he laid on his bed, his mind was moving very fast and his breathing was shallow and slow. He clutched the bottle of liquor in his hands very tightly and moved his upper torso up and took another sip from the bottle it burned his throat but the more he drank and less he would have to remember, the less he would have to be in the real world, or whatever world he was a part of now. He laid back down and his grip on the bottle faltered as it fell to the floor. He heard knocking at the door and was able to barely get out a "Come in." When the door clicked open he rolled over to hide his face, and his eyes that were red from the tears.

"Issei, how are you?" Asked Rias, she had become very concerned by Issei's behavior ever since the incidents.

"Fine" Issei Muttered.

Rias shook her head and left, when Issei heard the door click shut again he stumbled to the bathroom to indulge in his new addiction, however he was interrupted when a massive headache brought Issei to his knees, Ddraig began to speak.

"Issei, you need to stop partner. Its time you get some help, what you did was an accident, your plans caused it to happen, don't worry about it." Boomed the red dragon.

"Oh, hey Ddraig. Yeah but I chose do it." Issei said non-chalantly.

"Partner, please don't ignore my words. Just go to sleep." Ddraig spoke with authority.

"Fucking fine." Groaned Issei as he laid down, he loved and hated sleep, if it was dreamless he loved it, if he dreamed all he saw was what he did which he didn't like.

Issei closed his eyes and quickly nodded off, his mind however was still busy at work processing his deeds.

2 Months Ago

Issei opened the door to the house and a wretched smell overwhelmed his nostrils, he was slowly getting used to this smell.

"Issei, what do you see!" Yelled Rias as she stood outside with the rest of the ORC. Issei's green draconic eyes scanned the room and the lower body of a little girl which Issei deduced due to the fact of the small ripped blood- soaked skirt on the corpse.

"It's another victim." Said Issei coldly.

"Issei, can you say that again?" Asked Rias.

"I SAID ITS ANOTHER FUCKING DEAD KID!" Snarled Issei. This was the 23RD victim in a string of brutal murders in Kuoh, supposedly they were being caused by a stray devil. No one really knew the culprit however, Issei did and couldn't tell anyone, he just couldn't.

"Issei, you can come out I'll contact my brother." Said Rias in a soothing voice. Issei groaned and walked out of the house. Issei was the only one to go because the sight would cause the other members of the ORC to vomit, however Issei slowly became numb to it.

"Issei, I'm sorry." Said Kiba.

"Whatever." Said Issei with disdain.

"Issei, are you ok?" Asked Asia trying to lighten the mood but Issei simply ignored her.

"Well, big boy how about…" Before Akeno could finish Issei interjected.

"Get the fuck off me!" Issei growled at Akeno who put her breasts up agasint Issei. Akeno quickly backed off and meekly apologized as Issei simply kept walking away from the group outside the house.

"Pervert, where do you think you're going?" Asked Koneko

"Home." Said Issei as he continued walking. "Oh yeah, flat chest if you call me that one more time I will rip your fucking spine out and hang you with it." Said Issei casually. As Issei became out of range from the ORC Kiba spoke to Rias.

"President, I think something is seriously wrong with Issei. Out of curiosity when was the last time you guys slept with him?" Asked Kiba.

"Ever since the murders." Said Rias.

"Hm, do you think it is just the sights of the death or something else bothering him?" Asked Kiba.

"I think he has a million questions, however I don't have any answers. He is becoming more despondent, all he does is train he hasn't gone to school in a few weeks." Said Rias.

"I know, I was hoping you just might know a little more since you are so close." Said Kiba as he walked away from the conversation. Rias pondered Kiba's words for a second and a frown produced on her little face.

Issei's Room

Robotically Issei rose from his bed drenched in sweat and staggered to the bathroom. He held onto the counter next to the toilet as he pissed. "Fuck me, what the fuck was that dream. Fuck Ddraig why did we sleep?" Asked Issei sarcastically. Issei finished and got dressed and headed downstairs to train. He would barely leave his room, but when he did it was only for training. Issei's door slowly creaked open and he walked past the girl's rooms and headed to a gym in the basement for his training session. Issei reached the room and quickly hustled inside. Issei turned the lights on and quickly turned on the speakers and played some music. "Kill Yourself PT 3 should be good for now" said Issei as he cranked up the volume. He began by doing very rigorous calisthenics. After around 30 min it was time for him to work on his sacred gear. He quickly summoned his balance breaker by merely thinking about it.

"So, Partner, your balance breaker has improved exponentially." Said Ddraig as Issei practiced fighting in his armor.

"Of course it has, after…" Issei was cut off by Ddraig.

"I know, you don't need to say, forget I mentioned it." Said Ddraig.

"Fine, Ddraig, what are we looking at in terms of power?" Asked Issei.

{BOOST} "Very good, we could take on just about anyone right now, reserves are also good. Power consumption in comparison to usage is also good. You are currently ready to take on a God." Said Ddraig.

"Good, I better fucking be after all I went through." Growled Issei. "Ddraig, do you think it was worth it? Honestly." Said Issei as he discarded his balance breaker and went to lift weights.

"You know my answer." Said Ddraig.

Issei let out a slight chuckle put down the barbell and went to leave the room, satisfied with his workout. "Yeah, I know the answer partner, and that's why you are the best partner ever." Said Issei.

Issei left the gym and went back up to his room to shower, he undressed and looked at himself in the mirror. He had gotten used to the red dragon scales growing on his legs and arms, it was easy to cover. Issei quickly got in the shower and bathed, after his shower he picked up the bottle took a few sips and went back to sleep.

The Next Day- Kuoh Academy

Rias was sitting behind her desk in the ORC clubroom, the sun was shining through open windows and the fall air swept in the room. Rias was alone dealing with paperwork pertaining to Issei, it was difficult to keep a student enrolled when he never went to school. Rias slowly moved her head and her red hair swung to the side when a figure appeared in the room. Her heart raced, it was Issei.

"Hello, president." Said Issei Coldly.

Before Rias could respond Issei summoned his balance breaker and charged at Rias, she began to scream and woke up in sweat. She had passed out on her desk. Again. She wasn't sure what was real and what was fake, she wanted things to return to the way they were. The door swung open wildly and Sona Sitri as well as her queen Tsubaki stood at the threshold of the entrance and Sona calmed down when she saw it was only Rias.

"Another nightmare?" Asked Sona.

Rias simply nodded.

"You should cut him loose before he drags you down." Said Sona.

Rias clenched her fists and yelled at Sona. "You don't know anything!"

Sona sighed as Rias sat behind her desk, fuming.

"I know a few things; your pawn is a damn rouge." Said Sona coldly as she left the room with Tsubaki. The door was slammed shut and Rias was left alone

"Oh, Issei. Please, get better…" Mumbled Rias as she went back to work on the papers spread out on her desk.

Underworld-Gremory Estate

Sirzechs was sitting at his own desk just like Rias, also attending to paperwork concerning the red dragon emperor. Sirzechs was beginning to suspect Issei of something, however he had no proof just a slight hunch. Sirzechs sipped on some tea and the door slowly opened to his massive office and Grayfia walked in with more tea for Sirzechs as he finished the last gulp.

"How is your inquiry into Issei going?" Asked Grayfia as she poured Sirzechs tea.

Sirzechs sighed and placed the paperwork on the desk. "Not the best, it just doesn't make any sense, ever since these murders Issei has been getting more powerful, no one is training him to my knowledge and even worse than that at the last rating game a month ago Issei singlehandedly beat the opposing team in one fell swoop, he embarrassed a high-ranking devil and his peerage." Sirzechs groaned. "What do I do?" He looked at Grayfia who just finished pouring Sirzechs tea and handed it to him.

"Rias has been giving Issei too long a leash, and Issei simply started moving so fast that Rias was forced to let go, Issei is slowly becoming a threat. I don't want to believe it either but I think you should put spies on him just to make sure." Finished Grayfia as she bowed and left the room. Sirzechs scratched his chin and pondered what to do with the Red Dragon emperor. Sirzech's eyes suddenly widened and he stood up from his desk and shouted.

"That's it! It has to be! The Pursuers of Peace!" Sirzechs fell back in his leather chair and contacted his spies. "Yes, I need location updates on Issei hourly, yes that is correct, thank you." Sirzechs ended his phone call and began rooting through evidence from the murders, every 3 murders had a strange cryptic message left behind, Sirzechs now needed to find a connection between the messages. He began combing over them looking for anything that would lead him to the 'violent' group, the Pursuers of Peace.

Issei's House

"So, partner, how much more time do I have until we need to go into phase two?" Asked Issei who was laying on his bed, he had the lights off and wouldn't move for hours, he had no motivation unless it was to progress his plan.

"I couldn't tell…Never mind, it seems it is already time for phase two." Finished Ddraig

"Really…I can feel it, that presence." Issei lowered his voice and could sense at least two devils outside his house. Issei summoned his armor and barreled out of the house, he moved at such a speed the air molecules around him became enflamed, as Issei caught one of the Devils before they could teleport away. Issei tightened his grip around the devil's throat.

"So, it's a betrayal than." Said Issei, before the Devil could plead or beg Issei simply snapped the Devil's neck.

"Now you can't interrogate them, nice job." Said Ddraig sarcastically.

"Whatever, it doesn't matter this is enough to start treachery and dissent within their own ranks." Finished Issei. Issei through the corpse to the ground and went back inside and laid down. His motivation sapped, again.

Kuoh Academy

"What!" Screamed Rias, the ORC had gathered to listen to Sirzechs explanation about Issei.

"Yes, I had to it was for his protection." Said Sirzechs.

"Protection? Why do you think he acted that way, he probably that they were spies for the chaos brigade!" Rias was still yelling, trying to defend Issei as best as she could.

"I am on the side of Rias this time." Said Azazel as he appeared.

"Azazel, where have you been?" Asked Sirzechs and the ORC as he had been missing for quite some time, ever since the murders.

"I thought I told you? I have been researching Issei and that new group you've been concerned about." Finished Azazel.

"New group?" Asked Rias.

"Yes, the Pursuers of Peace, they are a violent group of renegades and terrorists." Said Sirzechs as his eyes glowed red with ruin.

"Have you contacted chief Michael yet?" Asked Azazel.

"Yes, we will be having a meeting in the underworld soon." Sirzechs stopped for a second and began again, turning to Rias. "Rias, can you and your peerage provide security for the event?" Asked Sirzechs.

"Of course, when will this meeting happen?" Asked Rias.

"The day after tomorrow. Now, I must go. Rias, don't bring Issei." Sirzechs teleported away.

Issei's House

Issei had passed out and was asleep in his bed, his red dragon scales had even begun to grow slightly on his neck. His mind quickly remembered what sent him spiraling down this path.

3 Months Ago-Underworld

Issei was wandering the grounds of the Gremory estate, it was before a practice rating game. Issei's perverted mind would never be the same again. His innocence would be lost. A robed figure appeared in front of Issei, behind the robes Issei could see what looked like a knight's armor, it was black and underneath the hood Issei could see a helmet, it glowed a black color and a putrid aura extended out and Issei's skin crawled.

"Who are you!?" Issei stammered while summoning his sacred gear. {BOOST}

"Who Am I? It doesn't matter, I am here to help you." The figure pulled back his hood and removed his helmet, the helmet disappeared and it revealed a man who appeared to be in his late thirties, he had long black hair with gray streaks, his face was an oval and his chin and jawline were very pronounced, he had a slight mustache and seemed to be very handsome. "Issei, do you wish to protect the ones you love?"

"Of course I do!" Issei yelled.

"Do you think you have the power to do so?" Asked the man.

Issei stopped for a second and thought on all the times he got his ass kicked, but he also thought of how much stronger he had become. "Yea…" Before Issei could even finish the man quickly charged forward with such a speed and drew a long sword Issei couldn't even notice it. Issei jumped back.

"Fool, how will you protect the ones you love?" Asked the man who sheathed his sword.

"What is your name?" Asked Issei.

"Oh yes, I am sorry, however, my name is irrelevant to you. I need to show you something boy, come here." The man said.

Issei slowly walked over and the man placed his armored hand on Issei's head. "Relax, I am going to show you something." Issei was tense but tried his best to relax.

Issei was transported to a different world it seemed like, it was Kuoh but the town was on fire, bodies could be seen high into the sky. The sky was black and the sun was red. Issei was standing in the street and suddenly a massive blast of blood rushed down and Issei tried to run but it encompassed Issei and he couldn't breathe. His mind went black and he was sent to the ORC room, the bodies of his comrades lay at his feet, Issei was now in his balance breaker and his hands were covered in blood. Issei could see Rias's body, it was mangled and it was her blood he was caked in. He was holding her head in his hands. Issei screamed out in agony and the vision disappeared. Issei was now back in the underworld. He was on the ground panting for air and the man kneeled down and lifted Issei up.

"Did you see?" Asked the man.

Issei didn't respond.

"That could be the future, your power will drive you mad, your desires will destroy and consume those around you. I ask you now, will you still refuse to hear my offer?" Asked the man.

"What…is…it" Panted Issei who was holding is head in pain.

"Simple, we destroy the supernatural, you will kill billions if you continue your path to ruin. Those with power are doomed to into temptation. As will you. If you want to prevent a war, don't you think killing the sides before they can fight will stop it?" Asked the man.

"That would be a genocide…" Muttered Issei.

"Perhaps, if you want to protect the ones you love sacrifices must be made. You should know this." Said the man.

Issei didn't respond.

"I will have an emissary of mine contact you, until than I need you to kill someone innocent. It doesn't matter who…" Issei quickly interjected.

"FUCK YOU! I WON'T…" Before Issei could finish the man punched Issei in the gut.

"I could always kill those you love now, it is up to you. You will become stronger the more you kill, trust me." Suddenly a horse appeared, the man got atop the horse and galloped away, leaving Issei with more questions than answers.

"Ddraig, who was that?" Asked Issei.

"I couldn't tell you, I don't know. However, what he says is not a lie. He gave you power and the only way to unlock it is with sacrifice. Issei, the choice is yours." Boomed Ddraig.

Kuoh- 1 hour later

Thoughts of power and lust took over Issei's rationale side, he craved power and the desire to protect those he loved. Issei observed houses and found someone, it looked like an older man. In his forties wearing a suit and returning home from work. Issei entered the random house, and simply decapitated him with Ascalon. Issei felt something strange, Issei apologized but before Issei could escape the man's wife came downstairs and screamed. Issei was forced to kill her too, then two children ran downstairs. Issei stopped for a second and froze, he couldn't do anything. He just couldn't but before he could do anything he fell to his knees and the moment he did the two children, brother and sister were eviscerated by the blade of another man Issei had not seen before. The man was wearing red armor, it looked like the black one's armor but it was red and emitted a rancid red aura.

"BASTARD!" Issei charged the armored man but was met by a fury of strikes, it left Issei bloodied and near death.

"If you wish to live, you will find a way. I would hurry though. I am sure what you call 'police' will be here soon. A horse appeared again and the man galloped away and disappeared.

"Ddraig…" Issei muttered, he coughed up blood and his vision went black.

Issei's Room-Present Day

"FUCK!" Issei rose from his bed once again drenched in sweat, his whole body felt heavy. He stumbled out of the bed and reached for the bottle of liquor he kept on his nightstand, he chugged it down and fell to the floor. He fell asleep and this time he didn't dream.

The door slowly opened and Rias looked in at Issei.

"Issei, I am SO sorry." Rias closed the door and left Issei to his thoughts, his mind truly was broken.

Thanks for reading, I hope it wasn't all over the place. Hopefully chapter 2 will be better.
