A/N just read highschool DXD; path of the sekiryutei and fucking loved it so I thought I would write my own version using the same concept.

Chapter 1: Red dragon hunter

Issei Hyoudo was 5 when he found the secret of his birth. He was 5 when his parents were taken from him by the fallen angel Raynare. He was 5 when Sirzechs lucifer took him in as his apprentice. Issei Hyoudo was 5 when he became the red dragon hunter.

For young Issei life was fun and normal for a 5 year old, however his parents kept a big secret from him. He found out in the worst way possible.

It was late at night when he was awoken by a nightmare and a explosion. Seeking the protection of his parents Issei when to their room, He knocked but got no answer, So he knocked again only louder, he again got no answer. Issei was getting sadder and more scared the longer he was stuck in the dark corridor of house. Pushing through his fear Issei decided to enter his parents room.

Upon entry he found it was empty. He then heard a sound from down stair and decided to see if it was family having a late night snack. The low down the stair he got the more scared he became, He felt something dangerous down there but decided to keep moving.

As soon as he got down the Stair Issei was left with destruction everywhere, the walls were missing, the furniture was destroyed all was left was rubble. His mother laid dead on the floor near where the kitchen was, she with left lying in a pool of blood around her growing bigger as the seconds passed. Even at a young age Issei knew this was bad, He didn't know she was dead but he knew she was hurt. Issei wanted to go to his mother and give a plaster like she would when he was hurt but he could move something was stopping him.

That thing was his father magic. Issei dad stood beaten and battered but still standing, Devil wings spread and his hand pointing to Issei making a barrier between him and the conflict. Issei saw a dark haired girl with black walk over to him with a glowing spear in her hands. "Are you ready to die you devil filth, any last words before I kill you and stop your son from discovering who he truly is."

Issei father spat at the girl and spoke. "Shut up you bitch, my son will be stronger than any of his ancestors, He will hunt you and destroy you, my lord as promised it." He then stopped talking and started chanting. " I lord (insert name here:) ) release the power holding back my son and offer his service to you my demon king Sirzechs. I chose you to train him and make sure he is ready, please hear my call you owe me damnit."

Issei father finished his long chant and then raynare stabbed him, "You demon king won't be saving you or your son to day, Demon filth."

Suddenly a flash of red blinded everything and from it came a large,strong, red haired man with battle armour on came out soon over the body of a dead devil, Issei father. "I am Sirzechs lucifer. King of the devils, you have killed one of high council and now I will make you pay. I place a bounty on your head. Know from this day forth you will be hunted by Issei until you take your last breath now leave or else."

Raynare not wanting to face the wrath of Sirzechs left the battle laughing and asking how a 6 year old hybrid boy could hunt her but little did she know.

It was then that Sirzech took Issei in, He trained him for 2 years, he told him everything; About hybrids, Devil, angels, fallen angels and of course about the dragon kings and emperors. It wasn't until Sirzechs sister Rais was ready for training that Sirzechs asked Azexel the current Governor general of the fallen angels to retire to train the boy to be bounty hunter for the pair of them. Azexel Agreed and trained boy for another 5 years. Stepping down to become Sirzechs 'advisor' on all thing fallen angel.

/ Issei at the end of his training./

Issei breathed heavily. He had been fighting the damned fallen angel lord for about 2 hours now and still couldn't lay a finger on them, The other target that Azexel had given him so fair we a lot easier than this. Thankfully this was training so he couldn't die as easierly. The fallen angel lord sent another blast to Issei, Issei dodged it and then tried to find a way to defeat the bastard.

"Draig any ideas." Issei asked as another blast hit him.

"Boost…. No sorry partner, I don't just keep dodging." Ddraig said with little encouragement.

Another blast hit Issei and he fell to his knees. "The only way you're going to defeat me boy and pass the test is if you use you balance break so come on do it,"

The fallen angel mocked. Issei just smirked. "Why thank you sir." Issei spoke as he waited for Draig to enhance him.

"Boost. Scale mail ready." Draig informed Issei.

"Activate balance breaker, Red dragon scale mail, type one," Issei yelled as his body was consumed in a red light. Once the light vanished Issei was left with his armour. It was lightweight and offered little protection, However it allow Issei to be faster. His attacks didn't get any stronger so Issei had learnt to use his speed to dish out fast light attacks to win the fight. Issei then yelled the name of his armour type. "Angel hunter."

The fallen angel lord was scared now. "Azexel didn't tell me about this."

Seeing the fallen angel's fear Issei attacked, using his speed Issei closed the distance. But when he got close Issei disappeared only to reappear behind the fallen angel. Issei sent single punch to the fallen angel's back before moving again with great speed to the front it. He then kicked the fallen Angel's legs and made him fall. "This is over," Was all Issei said before sending his elbow with great speed to the back of the fallen angel's head knocking him out.

As soon as the fight was over Issei heard clapping from the sidelines. It was Azexel, " Well done Issei you just need to work on getting you gear to boost faster. But here I got another name from Sirzechs."

Azexel handed Issei a piece of paper. 'Your next target is a fallen angel and stray devil known as seletria. Her hunting grounds are in the old shipping house by the docks.'

After Issei read the piece of paper he said bye to Azexel and left the underworld. Once Issei returned to his home which Sirzechs built for him spected to Issei plan 1 year ago for his 15 birthday, Issei was over joyed not to have to live with Azexel anymore, His snores made the house shake.

The house had 4 rooms downstairs and 3 room up stairs. Down stairs was a training and work out room which was equip with all the latest gym equipment and a section for sword practise and a shower. The next rooms were and living room with 4, 2 man sofas as well as 3 one man chairs, a bookshelf with human books and a secret compartment with devil history books and techniques inside of it, The living room also had a 40 inch Samsung TV. The next room was a kitchen with every you would need, there was a small off this that had a dining table that could fit 10 people on it, however Issei tended to eat in the living room watching Netflix. The final downstairs room was spare bedroom, That had a wardrobe, A queen sized bed and an ensuite the walls were painted white and the floor was wooden just like rest of the house. ( most of the other bed room were like this.)

The upstairs had a normal bathroom and 3 bedrooms 2 of which were the same as down stair and the other was Issei's, Issei had a king sized bed and had red painted wall as well as a ensuite. There was a bookshelf full of games and a 32 inch Tv with a xbox one attached to it, there was also a secret portal to the underworld that Issei only had access to when he spoke the password.

Issei finished touring the house making sure he had no intruders. Once he done this Issei started to make himself some food. As he was the red dragon emperor he would eat 3X the amount a normal human would eat. Issei plated his food which was a pleasant roast lamb breast (Yes the whole breast.) with minted new potatoes and seasonal veg. Issei carried his large plate of food the living room and turned on the Tv, he was about to start to eat when he heard his doorbell ring.

Issei got up and walked to the door, once he got their he and opened it he was met with the girl he had only seen photo's of in Sirzechs office when he handing in a contract. Before him stood. Rias Gremory. Sister of Sirzechs lucifer and more commonly known as the Ruin princess.

"Hello I'm Rias gremory your new house mate."
