I don't own high school DXD or monster hunter world.

Man monster hunter world is AMAZING! The graphics, the textures, the monster, the game play. ITS SO GOOOOOD. WHY DIDN'T THIS GAME COME OUT FASTER! But not like I can't complain I played for at least 140 hours. NO REGRETS! And because of that here I will release this base on my new favorite Elder dragon Val Hazaak. Enjoy.

Prologue: the Mist

Kuoh Park

It was a nice sunny afternoon perfect for a date. Which Issei thought as he had his first date ever with a beautiful perfect hourglass body name Yumma-chan. That was until she showed her true colors and revealed that she was a fallen angel. And that she was only toying with the perverts heart and killing him with a light spear.

After the Deed the Fallen than flown away but before saying one last thing "It was fun Issei. Even if it was the most boring time in my life. Seriously didn't it seem weird that a girl would actually like you? But That's why you will die as a pathetic virgin right here and right now. HAHAHAHAHAHHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHHAHAA"

Issei barley conscious heard everything and began shedding tears. Sure he was a pervert that peeks into girls changing lockers or talk openly about breast or how he wants to build a harem. But was that really enough of a crime for him to suffer both having his hearth being rip out of his chest by the girl he genuinely had affections for both figuratively and literally. No, it wasn't, that what Issei and the being residing in his body thought.

"You didn't deserve this, my host. No, you didn't. But don't worry I won't let you die here and I shall kill those who were responsible for your suffering." Was what a voice said creepily inside our dying pervert head before he lost consciousness.

Than dying Issei body began to emit a thick brown fog which first began enveloping the park. With devastating results first the ground began to spilt and dry up. Then the lakes, ponds and rivers water starter to boil and turn acidic which killed all of the aquatic wildlife that resides in them. The plants in the park were not in good shape either. Instead of dying the fog began to mutate them. Making the once beautiful flowers become ugly and deform, and the trees well all of their lush green leaves were now gone and replaced with weird pods that ooze out a deadly purple poison.

Luckily no Humans were harm by the mist. As the fallen had cast a ward in the park to ensure that no humans would come and witness the murder. This ward, however, did not work on the animal. So the stray dog, insects, reptiles, and birds were all present when the mist hit them. Which at first did do anything to them

But After the brown fog finished terraforming the park into a wasteland. The mist then began to mutate them first were the dogs. Which began to shed their fur leaving behind their bare skin which started to deform and resemble muscle tissue which was pinkish in color. It then grew in size roughly to the size and hight of a rhino but was much more linear and faster. In each paw grew an extra pair of long claws which was sharp enough to cut through steel also it grew bone-like protrusions sprouting from its back and tail. These beasts were called Odogaron and they are known in the underworld to spread a deadly diseasecalled eternal bleeding. which causes the infected to loses the ability to heal wounds and cuts and lacerations begin to form on the skin causing the victim to bleed out within 24 hours.

After the dogs, it was the insects, which for the majority just increase their size to the size of a Chihuahua. Except for a few battles that grew to the size of a human and have mantis-like front legs, a pair of collapsible wings, and had a giant singular greenhorn on its head. These were Setlas male droids that follow the directions of there master a Setlas Queen. Which began to burrow out of the ground. When compared to the drones the Queen had a totally different anatomy structure. She was bigger than them, can't fly, is more armored than the drones, has six limbs, four of which make contact with the ground, the other two being used for digging and grasping prey. In addition, she has a long, segmented tail with a large pincer-like structure at the end. Setlas is famous for one thing spreading a plague called the thirst. Which the victim would become greatly dehydrated as the body begins removing a large quantity of water in any way possible, with diarrhea, sweating, vomiting, and peeing. Death occurs in two to three hours.

From the reptiles side, the majority just grew poisons fangs without any change in body size. And this poison was deadly I drop means instant death to anyone so unlucky to be bitten. Except for one group lizards that grew to the size of a house and had become almost chameleon-like from its independent moving eyes to its long and elastic tongue that was as long as its body. The only difference that this creature had with real-life chameleon besides its size was that it had powerful wings that allowed it to fly and that the fact it can turn invisible. Because of its similarity to chameleons these creatures a called Chameleos. which spread a disease called bloching. That causes every part of the victim's body to turn purple. Which is followed by vomiting purple blood, seizures, and insanity from the constant pain. Death comes slow to the victim that happens between two to three weeks.

And finally, the birds which simply grew teeth grew at minimal to the size of eagles and become so aggressive that they would simply attack any living thing that was not associated with the brown fog. All except one owl that grew to the size of a giraffe and has blue plumage. This thing is called a Malfestio and it spreads the deadly disease called the Sleep. Which causes the victim to sleep and never wake up.

All of these name creatures above are listed as S class threat level creatures in the supper natural world. As these carriers carry pathogens that currently has no cure and with a mortality rate of 90 to 95 percent. Why are these dangerous creatures appearing in Kuoh you ask? It was because he created them to do one thing and one thing only. To avenge the betrayal of his host.

"MY MINIONS YOU ARE HERE FOR ONE THING AND ONE THING ONLY. AND THAT IS TO EXTERMINATE THE FALLEN THAT RESIDES IN THIS TOWN. NOW GO AND DESTROY THEM" as soon as the voice stops every creature in the park than began marching to the current location of the fallen guided by the fog.

Fallen angle headquarters abandoned church

Back in the fallen lair the bitch was still laughing and celebrating a mission well done.

"really that morron didn't see that coming and you guys should see his face when I told him the truth. It was priceless. HAHAHAHAHAHHA"

"oh man, I wish I was there. I would like to see the face of despair of idiots like that. Really Raynare next time brings me to those type of missions." Said by a fellow fallen angle which looked like a young blond child in a Gothic Lolita attire.

"maybe next time Mittle, but enough about that. Hey, Kalawarner how about you did you killed your target as well? " Raynare ask a fellow angle that was a tall and buxom woman with long, navy blue hair that obscured her right eye and brown eyes. Her attire consisted of a maroon, trenchcoat-like top with a wide collar, a matching miniskirt, and black heeled shoes.

"what do you think? Of course, I killed him too. It was so easy it was like shooting fish in a barrel." Kalawarner said as she was about to grab a nice cold beer.

"ohhh pass me one Kalawarner" the goth loli ask.

"isn't it too early for you to drink Mittel," Kalawarner said with a mischievous smile.

"Gezz not this again you know we are of the same age." Mittel than pouted. Making all three of them laughing joyfully. With the other stray priest and other fallen angels also enjoying the relaxing atmosphere.

Which was going to be destroyed soon? Very soon indeed.

Well that's about it for now

Hope you enjoy.
