I Do not own Highschool DxD, all credits to its creators.

A seven year old boy named Issei Hyoudou who was walking back home depressed, arrived at his street.

"Why'd you have to leave Irina?" Issei asked himself. As Issei arrived at the door and then opened it was greeted with the most horrible thing of his life. His parents were lying dead at his feet, his father had no jaw and his eyes were pulled out and he was missing all of his limbs. And his mother had her stomach completely cut open and her body was completely tied in piano strings hanging on the ceiling. After Issei fully took in the sight he ran outside about to throw up and was crying. But just as he exited the door out on the street he noticed a figure. It was a five meters tall humanoid mechanical lifeform with three eyes.

"What…..are….you?" Issei asked, losing himself to sadness.

"Oh it seems I have one more to take care of." The unknown being says. I am Rugatimu, an evie god and servant of Regalzeva. I came here to observe this world to report it back to Melvazoa our leader, but I decided to leave my mark on this world with a blood sacrifice." The now named Rugatimu explained.

"You did that to my parents?" Issei said with a breaking voice.

"Yes, but don't worry, I don't leave undone work behind." Rugatimu said as he takes a battle stance.

"AHHHH!" Issei screamed as a red device that looked like a gauntlet appeared on his hand. "I, who am about to awaken, Am the Heavenly Dragon who has stolen the principles of domination from God, I laugh at the "infinite", and I grieve at the "dream", I shall become the Red Dragon of Domination, And I shall sink you to the depths of the crimson purgatory! Juggernaut drive!" Issei chanted as he now has the appearance of a large red dragon, then he charged at the evie expecting to win but unfortunately for him the evie merely punched him and he was back in his regular human form with multiple cuts and scars.

"You must be an idiot, my power rivals the so-called "strongest existence" that your supernatural world has labeled. Do you really think the power you have compares to anything I have?" Rugatimu says. "Now without wasting any more time I will take my leave." Rugatimu says while about to take off, but just as he was about to leave he felt something horrifying to him. He turned around to look at the boy only to find that he was completely healed.

"No….." Issei said as a green aura surrounded him.

"Nooooooooo!" Issei screamed at the top of his lungs as the entire planet started to shake. Then more to the evie's surprise Issei not only started screaming but also laughing. "Maybe he's losing his mind to the power." he thought as Issei continued. Then soon after thunder and earthquakes started to form, then after when it look like Issei calmed down his body absorbed the green aura and his hair turned pure black, Rugatimu thought it was a good time to attack when, Issei started to scream again much louder than before and just after a bright green aura escaped his body and a few seconds later it started to do so at an alarming rate, then his body started to seemingly break apart then suddenly a bright green explosion came from the body of the boy as the area he was surrounded by was covered in the explosion making a small crater, then the energy that was still covering him emitted strange hums of energy that covered the sky and the environment in different colors, first wave covered it in a purple color, second wave covered it an a gray color, and then the imploded aura that Issei was surrounded in covered everything. Then Issei absorbed the aura back, turning everything back to normal but Issei on the other hand. He now looked like an adult who towers at 274 centimeters, also has an extremely bulky physique with his hair now standing up on it's ends as well as his hair color now being emerald green. And his clothes were different. He is shirtless while wearing white pants with a red sash draped around his waist and secured by a black belt with a green gem-center. He also wears similar red boots that go up to his knees with a green gem at the top the front. As well as two red arm bracers that look just like the boosted gear gauntlet but it only covers half of his arm and doesn't cover his hand.

"This power…What are you?! " Rugatimu shouts in disbelief. Issei seemingly regains a little bit of sanity and walks over to him with a sadistic smile.

"Too late for regrets now." Issei said. His voice matched his appearance. It was dark, cold and sadistic and was more adult-like than his child voice which sounded sweet. Just after Issei said that he charged at the evie only for him to dodge without ease. Then Issei fires a beam from his mouth which hits the panicking evie.

"This is bad, from him merely using a rush-attack I was already heavily injured. I must hurry and get out of here and report this to Regalzeva." The evie said to himself as he opened a portal and was about to leave, but then Issei at unreadable speeds came in and grabbed him by the leg.

"Leaving so soon?" Issei said as he threw the evie back to the ground, then proceeded to beat on him like he was a ragdoll, then eventually using him as a trampoline. Issei was very sadistic in this form and was not making his enemy's death any slower. Then Issei decided he had enough fun ringing out the evie then charged an energy-sphere type blast, but before throwing it at him he picked up the evie, then threw him to the outskirts of his town Khou in a large forest area.

Issei then shouted "Good bye!" as he threw it at him obliterating the forest and the evie with it.

"Sigh* pant* Getting stronger, the power is rising too much!" Issei said as he then yelled and powered up seemingly. Then he covered himself in a sphere of energy and quickly flew to the ocean. Then he started screaming loader as multiple energy blasts the same as the attack he used to kill Rugatimu fire's out of the sphere. All of the attacks landing in the ocean while still exploding. Issei then seemingly calmed down as he flew back to his house, he then screamed one last time as he seemed to go back to normal size with his torn outfit. As soon as he went back to normal, Issei started crying remembering what happened. An hour later the police came to his house and found his parents dead. The police asked Issei what happened but he just said that he didn't know and that they were like that when he came back. Then they asked if he had any other relatives and he said he has an uncle. The police then called him after Issei gave him the contact information. They then told him the situation and said that he was going to move into town anyway and that he was going to take care of Issei. After 3 hours his uncle arrived at Issei's house and unpacked all of his assets.

"Hello Issei, I have to say sorry for your loss." His uncle said.

"Thank you uncle Jin." Issei said sniffling, identifying the man as Jin.

"So Issei, I have a question for you." Jin asked.

"Yes?" Issei said.

"Do you know about the supernatural?" Jin asked, to Issei's surprise.

"W-What?" Issei says.

"I felt the power from your fight with that guy whoever he was. And your power could have been felt everywhere if I didn't put up a barrier before you killed him. When you were born I suspected that you had a sacred gear, possibly even a longinus, but I didn't expect you to become this strong." Jin explains

"S-So how strong am I?" Issei asked.

"Right now in your base state which is what you are right now. You are as strong as great red, the strongest existence." Jin explained. Issei remembering the evie saying that he rivaled him so now he speculates that he is not absolute.

"So how do I use my sacred gear?" Issi asks.

"Think of a red gauntlet." Jin says. Issei does just that then a red gauntlet appears. "Oh the boosted gear huh?" Jin says as he notices something wrong with Issei.

"What's going on?" Issei says.

[Class up: Vanguard!] a voice from the gauntlet announced. Just after a green blast hit Jin, but to his surprise he wasn't dead, and to his shock he felt like he had power.

"What is this?" Jin asked.

[It's one of the new abilities I received after my host made that new power extension that not even I was expecting.] The voice explained.

"W-Who are you?" Issei asked.

"That is Ddraig, one of the two havenly dragons." Jin told Issei.

[That's right, and I will be the one training you to utilize your power!] Ddraig said with pride

"Alright." Issei said.

(Evie Etoulde)

"Regalzeva I have something major to report!" Said an Evie

"Go on Durmado." The identified Regalzeva said. Regalzeva is a seven-meter tall mechanical humanoid with five eyes in total; two on each side and one on his forehead that shines with gold. His body has a tint of black and purple with thick limbs.

"Rugatimu has been destroyed." Durmado revealed.

"What!? By whom?" Regalzeva asked with concern.

"I don't know who the person is because they disappeared shortly after killing him but he was destroyed easily by a huge man with a hugely powerful aura, but it seems like he is new to that power seeing that he had trouble controlling it.

"Interesting. For now we will postpone our invasion on draconic deus. Inform everyone and my brother Melvazoa." Regalzeva ordered.

"Yes sir." He replied.

Time skip

(Ten years later)

Issei is now 17 years old in his khou uniform. He is now 5.58 feet, and his hair is black. He entered the school and found his new classroom

"Now, everyone, we have a new student here, come in now!" The teacher said.

"Hello everyone my name is Issei hyoudou, I hope we can all get along well." Issei greeted and bowed, the girls looked at him cutely while the boys just scoffed at him. Issei continued his day at school completing his assignments and completing them with perfect scores. Then after school Issei was thinking to himself.

"Maybe there are supernatural people at the school, I was able to smell something. What do you think Ddraig?" Issei asked mentally.

{There are devils in the school, I was able to pick up the scent as well.}

"Is that right? Well I better be careful." Issei responded.

{Yes but if you do get into anything major, don't waste my training alright?}

"Alright Ddraig." Issei responded innocently.

(Occult research club)

''Bucho, is something wrong?'' A girl with a buxom figure around one year older than Issei with very long black hair and violet eyes asked. Her hair is tied in a long ponytail, reaching all the way down to her legs with two strands sticking out from the top and sloping backwards, with an orange ribbon keeping it in place. ''Ah, Akeno. No, I was just lost in thoughts.'' A beautiful young woman who appears to be in her late teens with white skin, blue eyes and a buxom figure answered. Her most distinctive feature is her long beautiful crimson hair that reaches down to her thighs, with a single hair strand sticking out from the top. Her hair also has loose bangs covering her forehead and side bangs framing her face. ''The boy who transferred into the second year today, do you know something about him?'' Akeno served the redhead a cup of tea, tilting her head at the question. ''Ara ara Rias, are you interested in our kohai? All I know is his name, Hyoudou Issei-kun'' Rias put a chess piece on the board that was on the table. ''Who knows? Checkmate, I will take a shower.'' She walked off to the shower inside the clubroom, starting to undress on the way. ''And here I thought I made the problem more difficult this time.''

(Hyoudou residence)

"Hello uncle Jin!" Issei greeted.

"How are you doing issei?" Jin greeted back

"I was really good, everyone was nice and I passed all my classes today at school." Arata said.

"That's really good and to think you met great red a year ago now that I think about it." Jin said.

(Flashback)

Issei and Jin were training under Ddraig's influence and then a portal to the dimensional gap suddenly opened then Issei was pulled in by a huge red western dragon.

"Hello there Issei." Great red greeted.

"Hello there, you're not going to try and kill us are you?" Issei asked.

"What no! Why does everyone think I'm petty? I know I act like a delinquent but come on!" Great red exclaimed.

"Well sorry but why did you bring us here?" Issei asked innocently.

"Us?" Great red asked, now smelling Ddraig on Issei. "Oh it's you Ddraig, I didn't notice you until now."

{Yes I'm honored to see you.} Ddraig said from the boosted gear.

"Anyway I'm here to thank you Issei." Great red said to the confusion of Issei and the shock of Ddraig.

"Thank me? For what?" Issei asked.

"Remember what happened to you nine years ago with that evie?" Great red asked getting a growl from Issei at the mention of "evie".

"Yes, but what did that have to do with anything?" Issei replied with a voice full of poison.

"I'm sorry about what happened to your family but I want to say thank you because that guy was actually a pain in the ass." Great red answered.

"Huh?" Issei asked in confusion.

"You see, I had absolutely no knowledge of the evies until he showed up, then I found out that his power actually rivaled mine and he talked about having a boss higher than him in power so that ticked me off, but after you little episode let's just call it. It actually took a load off my shoulders though I do know that you are stronger than me even at your weakest state." Great red explained.

"Oh well your welcome then, as for his boss he said he was a servant of someone called Regalzeva I think. Issei said.

"Hmm, alright anyway see ya I'm sending you back." Great red told Issei.

"Alright bye bye." Issei said as he entered a portal to earth.

(Flashback end)

"I didn't expect that either." Issei said to his uncle. "Also someone was following me earlier so I caught them

(Flashback)

Issei was walking back home from school but he sensed he was being followed by a little white haired girl. Issei tried to lose her a few times but was still followed then he decided to walk into a tree escaping her voisin.

"Where did he go? The girl thought to herself. Then she looked behind her and saw that the guy she was following was right behind her.

"Hello there! Why are you following me?" Issei asked the girl.

"I-I was not." The girl replied.

"Come one now I sensed you trying from the beginning. What did you need?" Issei asked.

"W-Well." The girl said just as she noticed Issei was smelling her. "What are you doing?" She asked.

"You're a necomata?" Issei asked only to get an absolute look of shock and fear from the girl. "Hey come on now I don't mean any-" Issei said but suddenly he got a blush and then out of instinct he hugged the girl.

"W-Wha." The girl said as Issei stroked her back. Then he noticed two cat ears coming out of her head to which he blew in. "A-Ah!" The girl moaned as Issei continued, then saw a tail come out of her then he stroked it which made the girl blush heavily. "U-Uh Issei!" The girl moaned but Issei regained himself then he quickly stopped.

"S-Sorry about that I kinda lost myself back there." Issei innocently replied.

"Why did you do that?!" The girl asked with fear and embarrassment.

"My dragon instincts made me do it. I'm sorry." Issei apologized.

"You're a dragon?" The girl asked.

"Yes, well 10% dragon." Issei replied to the girl's understanding. "By the way, what's your name? I know we go to the same school. I can see the uniform. But I don't know your name." Issei said.

"I'm Koneko." The girl now known as Koneko said.

"Oh well nice to meet you." Issei said. "Well got to go now, bye bye!" Issei said.

"Bye….." Koneko said while blushing.

(Flashback end)

"Hahahahaha! Don't worry about it, Issei." Jin said. "Anyway do your homework then we can turn in for tonight." Jin said

"Alright!" Issei said. After finishing his homework Issei turned in for tonight.

That's the end of this chapter for the new Highschool DxD fanfic I made here. BTW: from the fight up there I just made Issei's version of legendary super saiyan but as a part of Ddraig but mainly Issei. Hope you will enjoy this fanfic see ya later!
