The Alliance: The marriage of Princess Izuku and Dragon Prince Katsuki

Izuku and her gang

Long ago, the world was shrouded in darkness. And in that darkness, was all types of living beings. Humans, fairies, dragons, vampires, ogres, demons and many more monsters. It was a kill or be killed world, especially for humans, since they were weakest and most delicious amongst the food chains.

Humans were being eaten, kidnapped, rapped, possessed, enslaved, their souls being used for demonic rituals. All the horrible things you cannot imagine. The torture and pain went on for hundreds of years. Until one day, hope was born. The very first human with magical powers of light. He shined the light of hope in the darkness and led his people to safety.

This light, it was called One For All.

This power he weald, not only made him strong enough to fight off the monsters and protect his home. But he was also able to bless his people, giving them powers of their own to weald. Soon, humanity had mastered many things, such as fire to burn vampires. Greenlight to heal the weak. Ice to freeze the wicked. And even fertility, to make healthy children. All of these, they were gifts...but it came at a price.

One For All would eventually grow weak at a young age. All the gifts he had given was like taking bits away at his soul. Humanity tried their very best to save him, but all their effort was for nothing. Eventually, he died...luckily, he had a son to carry the dark secret.

(Present)

"This looks rare, Izuku-chan! What about this?" A young female with pink cheeks and brown hair spoke as she walks over to her friend. In her hand, a light blue flower that seems to create dim lighting around her in the dark cave she was in. The flower was nearly the size of her hand! The young woman wore a large pink dress with a black corset outside that had black silk to tie the back. The corset pushes up her chest, making her bust bigger than some. The bottom part of her dress was tied up, allowing her left leg to be exposed. Showing off tattoos her of spells and her shoe.

"Ochako! Were in a cave of flesh-eating, skin wearing, raping ogres! Why the hell are you shouting!?" A young man with blue hair and glasses growled at the brunette. Ochako shrugs her shoulders at him as she walks over to him. stuffing the flower in her back pocket, she gives the young male a wink.

The young man wore mostly silver armor. His hair was cut short, with the tip of his bang hanging over his eye. He wore glasses, which was rare in the world, and also not needed since his vision wasn't that bad.

"I am not scared of big old ogres Tenya. Its gremlins we need to worry about, they're the fuckers that actually do some weird shit to you."Ochako muttered. "And speaking of ogres, their all sleeping. Its hibernation season, remember? The explosion was about to do won't even cause them to wince as boulders kill them. "

"The explosions arent to kill them..." A young man with white and red hair says. "It is supposed to keep them trapped hereafter they wakeup. If you perform well Tenya."

"I will destroy those rocks, no problem!" Tenya gowled. "All you two have to do is create the fire. Do not mess this up Shoto, we can't afford this!"

"I will not fail the kingdom," Shoto responded. Behind him, a dim yellow light was coming towards him and at high speed. The three look in the direction to see two females running. One of them was holding a large sack of the unknown, while the other had a sack on her back.

"THEIR AWAKE! RUN FOR IT!!"A green-haired female growls to the group before she begins to run out of the area. Behind was another green-haired female, although she didn't run, she was hopping behind her. After the two green-haired females ran past Tenya, Ochako threw a small sack of white dust to the ground before sprinting herself. Shoto, in fear, throws a spark of fire at dust while Tenya sends a large gust of wind in the direction. Soon, a line of fire begins to line in the cave, revealing large green skin creatures walking towards them. The two male wasted no time to turn around and run.

Soon an explosion happened behind them, causing massive junks and rocks and boulders to fall down behind them. The five young adults did not let the motion of the falling rocks cease their running. No, they kept running and running till they had reached the exit of the cave, which welcomed them with a bright shining sunlight.

Outside, a purple-haired male waits with three horses near him. He stood in front of the cave, not caring for the forest he stood in front, nor for the red eyes that stared at him. His only concern was his friend's safety. The cave was a downwards cave, meaning that if the rocks began to close in front of the group, they would be ogres food.

Luckily his friends made it out just before the rocks caved them him. Jumping out of the darkness and into the sunlight, the five young adults practically throw themselves onto the ground in relief. The explosion created a strong wave that pushed Tenya, Shoto, Ochako and the green-haired frog girl into a boulder. The other green-haired girl just fell face downwards to the ground. Unlike her friends though, she wasted no time standing up.

"WE MADE IT!" Tenya shouted as he claps his hands together. "WE DID IT!"

"Not so quiet." The green-haired female shouted. She hoists her hand in the air, allowing a bright green light to engulf it, once it was gone, a sword revealed itself. A thick silver blade with black writting on it. The handle was gold and it wrapped around Izuku's grip. At the end of the handle was a blue ribbon that flowed in the air.

The orge that was chasing them arose from the dust of the fallen rocks. Standing about 8 feet tall, he looks down at the green-haired female with his golden eyes. His grey teeth were not only thick but sharp enough to bite down onto someone's skull. Preferably a human's head.

"Princess Izuku..." The orge growled. "Ninth descended of One For All blade, and the daughter King All Might."

"An Orge that has the blood of our people on it!" Izuku growled back at the monster. She raises her blade over her head, holding it with two hands, preparing to strike at any moment. Much to the orge's laughter.

"Such a small thing you are. You will die like your people." He growled at her before charging. For creature he was quick, but not compared to Izuku's speed. He stops in front of her to slam his fist down towards her small body. Only for his hand to stop when her small hand gripped his wrist.

"Not quite." Izuku growled before, literally, throwing him over her back. Causing him to fall to the ground hard! In a flash of white, her sword slices off his legs and one arm. Purple blood squirts around his body as his voice fills the area.

"FUCK!!" He screams as he tries to crawl towards Izuku with his hands, only to have the princess slice his fingers off.

"Still think I am a cute little princess?" Izuku growled. The screams of the orge soon changes to laughter, baring his teeth at her.

"YOu RealLY thInK...that we didn't know about your attack!? As we speak, there is an army of my people, breaking down your walls!" The orge shouted at her. Izuku tilts her head a bit, not believe the words out of the monster's mouth. Until a large explosion was heard miles away, in the same direction of her home.

"The kingdom!" The brown hair girl shouted. The orge continues to laugh as the young adults stare in the direction of their home in fear.

"Now you will feel the same pain my peo- *SPLAT*

Rolling like a ball, the ogre's head makes its way towards the purple-haired male foot. He looks up at Izuku with a dull expression, not surprised, but not impressed either. Wiping the blood off with the ends of her dress. she waves the sword in the air to make it disappear before running over to a horse.

"Izuku!" The purple-haired male shouted, but the young princess did not listen. Instead, she kicks the back of her horse, making it run towards her home in haste.
