The Gremory manor is one of the biggest territories in the Underworld. Land owned by the Gremory family dating back to the Great War, and in his laboratory, Sirzechs Lucifer pondered at the events that have happened in the past couple of days.
He brushed aside notes that he had taken and tried to make sense of it all. Abnormal magic energy leaked from portals unknown in origin, creating freak natural disasters and unusual weather phenomena all over the world. Snow in the desert, heat waves in northern countries, even the animal life has been affected greatly. He and Ajuka Beelzebub have spent countless hours studying and trying to figure everything out, but one answer led to more and more questions.
He sighed and leaned back on his chair. His study was a complete mess. Books and research notes littered the floor, and with the curtains up, barely any light entered the room. He tried to make sense of it all, but nothing was making sense. Maybe an incursion from another world? But that idea was as good as mute since he had no conclusive evidence to back up his claim.
"Ah dammit!" He scratched his head. "Why is this all happening!?"
The door to his study opened and in came Ajuka. He didn't look much better than Sirzechs. His green hair was messy and unkept with bags under his eyes. "You're awfully loud this morning aren't you?"
"It's morning already?" Sirzechs asked.
"It's 10 in the morning Sirzechs," Ajuka walked over and spread the curtains, blinding Sirzechs with the sun's rays.
"It burns!"
"Get over it," Ajuka smiled. "No progress again, huh?"
Sirzechs sighed. "Nothing we haven't already come up with. It has to be an incursion, but…"
"But without any proof, there's no way anyone would believe us," Ajuka said. "You and I are still novices at being leaders, our experience doesn't lend us any favors either. We'll have trouble convincing the other High-Class Devils of this."
Sirzechs pulled out an old history book he had dug up from the Gremory Archive. "Look at this," He tossed it to Ajuka, who began to flip through. "There were myths of a group of individuals in the Great War. People who usurped divinity from the Gods and used that power to flip the balance of power between the Factions. They single handedly reclaimed humanity's seat of power in the power."
"You're talking about the Campione," Ajuka said. "Sirzechs, you and I both know that they were a myth. And even if they were real, the Campione died out a long time ago. There hasn't been any incident of a human killing a god in eons."
"I know, but," Sirzechs handed him one of his notes. "What if these weather phenomena are caused by the Gods. The book said that whenever a God has their Authorities usurped, their attributes will be reflected onto the world. This has to be the answer."
"Maybe you should get some sleep," Ajuka smiled. "You've been up a long time."
"So you don't believe me either," Sirzechs sighed. Although he couldn't blame Ajuka. The idea was so out of left field, Sirzechs felt as though he was grasping at straws to come up with anything conclusive. But even so, he couldn't shake the feeling that something much worse than freak weather was about to come.
There was a knock at the door. A small girl with short red hair and green eyes smiled. "Rias. What are you doing here? Shouldn't you be with mother and father?"
"Grayfia told me to bring you this," Rias held up a tray with a sandwich and a glass of wine. "She said that you're gonna need your strength if you wanna figure out what's going on."
"I see," Sirzechs walked over and rubbed his little sister's head. "Thank you, Rias."
Rias smiled as he played with her hair. "Brother, what's going on? You seem…tired."
"I've just been working a lot lately, Rias," Sirzechs told her. "You don't have to worry about me, okay? Tell Grayfia I said thank you for the food. I'll see you downstairs in a bit okay?"
"Okay," Rias smiled and ran off.
Sirzechs took the tray and walked back to his desk. Turkey with bacon and lettuce and tomato, his favorite. "That Grayfia…" Sirzechs could almost cry.
"She's really growing up fast, isn't she?" Ajuka said. "Soon enough she'll have her own household and become a High-Class Devil."
"Don't get me thinking about that, please…" Sirzechs couldn't bear to think about how Rias was going to grow up. She already had the Power of Destruction, if she gets anymore powerful, things could get…rough.
"Let's go downstairs," Ajuka said, placing a hand on Sirzechs' shoulder. "We really need to eat."
Sirzechs quickly finished the sandwich and went downstairs with his closest friend.
The dining room was already set by many of the maids in the manor. Sirzechs' father sat at the head of the table with his mother on his left. Sirzechs sat to the right of his father with Rias by his side.
"Long night, was it?" Grayfia asked as she placed a dish down in front of him.
"I have a feeling it's gonna get a lot longer," Sirzechs smiled. "Thank you for the sandwich, it means a lot to me."
Grayfia blushed. "Of course, my lord."
"Any progress so far you two?" His father asked.
Lord Gremory was a man of great power, and his confidence and stature exuded in his appearance. He looked around forty, with long crimson hair tied back and a beard. However his softer and gentler side shined through his smile and warm eyes.
"Unfortunately, the results have been the same, Lord Gremory," Ajuka sat next to Rias. "Every conclusion we come to has been the same."
"An incursion, was it?" Venelana Gremory, Sirzechs' mother, said. "This could be a problem."
Lady Venelana Gremory was a queen of kindred spirits. She was kind and fair to everyone. She looked around her mid thirties with long brown hair and kind brown eyes. Though she sometimes has her cunning and manipulative side, Sirzechs' feared that side of her more than anything.
"Do you think the others will believe us?" Sirzechs asked. "Surely with your backing…"
"I'm sorry Sirzechs," His father said. "We won't be able to help you this time. Our interference would be seen as favoritism, it could ruin your image in the days to come."
"I see…" Sirzechs said. He had hoped that he could have some help, but his father was right. He was the newly appointed Devil King, he had to start acting like one.
"Don't worry Sirzechs, Ajuka," His mother said. "I'm sure you two will figure it out, knowing the two of you."
"Thank you, Lady Gremory," Ajuka bowed his head.
After Grayfia and the maids presented the food, Sirzechs felt something. He took a look at his wine glass and noticed the liquid was swaying back and forth.
"Ajuka," Sirzechs said.
"Yeah," His friend replied. "Something's coming."
Both of them stood up and grabbed their coats.
"Brother?" Rias tugged at his shirt. "Is everything okay?"
Sirzechs smiled and knelt down, rubbing his sister's head. "Everything's okay Rias. Stay here with mother and father, okay? We'll be back." He stood up and looked at Grayfia. "Defend the manor, on your life."
"Understood, my lord," Grayfia bowed.
"Mother, Father," Sirzechs said.
"Go," His father smirked.
Sirzechs nodded and took off with Ajuka. They both ran out of the manor and looked up at the sky. There were storm clouds gathering in the distance. "Ajuka," Sirzechs said. "Contact Serafall. We'll probably need her help with this."
"What about you?" He asked.
"I'm gonna go on and investigate," Sirzechs created a magic circle and rode it towards the origin of this magic.
He had never felt anything like this. This intense magic energy, it was deafening. If he wasn't so used to pressure like this, Sirzechs' legs would have gave out from all of it.
As he approached the origin, he could see what was happening. A great beast rampaged in the outskirts of the Gremory territory. A dragon, easily 20-30 feet tall with eight heads and massive wings, tore through the landscape.
"A…A hydra?" What the hell was a hydra doing in the Underworld. It made no sense, a beast from mythology, a magic beast rampaging through the underworld.
As he got closer, however, Sirzechs could see something else. The hydra wasn't just rampaging, it was fighting someone. Who the hell could fight a hydra for this long and not be killed?
He saw lightning spark and flames ignited. There was a figure standing in front of the hydra, a person wearing a long white trench coat and a hood covering their face. However they were holding a trident, and the magic energy coming from this person was the most powerful he had ever seen. Sirzechs always though he or his father had the strongest energy in the Underworld, but this…this was something else entirely.
"Sirzechs!"
It was Ajuka and Serafall Leviathan. The two caught up to him on their own magic circles and seemed to caught on pretty quick. "Who the hell…" Ajuka was at a loss for words.
"We have to help him," Serafall said. "He'll be killed."
"Wait," Sirzechs said. "Something's happening."
Even from hear, Sirzechs could hear him speak. That voice, it was low and frightening.
"Hear me, for I am powerful," The figure said. "Hear me, for I am the strongest. For I am the King who has overthrown the threshold of divinity. For I am the thief who steals for himself the power which confers godhood." The trident began to collect power. Waves of fire, water, and electricity collected at the tip of the trident as he held it up.
The hydra began to roar. "Cursed Words of Power!" The hydra collected magic into it's eight heads and aimed at the man.
"Watch out!" Serafall shouted.
The man simply aimed the trident forward, and a massive blast of magic shot out from the trident and completely incinerated the hydra. The blast took out most of the surrounding landscape, but when it simmered, the hydra was beginning to turn to stone.
"W-What the hell just happened?" Ajuka asked, as confused as any of them were. "With a single shot…"
"He took down a hydra with a single shot…" Serafall said.
"What is he?" Sirzechs descended and landed behind him.
The hydra's stone body began to decay and vanished like sparks of light. Eventually, it's entirely body disappeared. Sirzechs watched as the trident began to disappear as well. He realized the situation he was in and took a breath. Time to act like a Devil King.
"Who are you?" He asked as Ajuka and Serafall landed. "Identify yourself."
The man turned around. He took off his hood to reveal the face of a teenage boy, no older then 19, with medium black hair and dazzling yellow eyes. He wore a long white trench coat over a black T shirt and black jeans and boots. He had an indifferent look on his face, but his eyes…
"Are you…okay?" Sirzecsh asked.
"Strange," The boy said. "You just witnessed me take down a hydra, and you ask if I'm okay?"
Sirzechs smiled. "Well it's not like we're enemies or anything."
"But you're…demons?"
Sirzechs was alerted of this boy's instincts. He could detect magic in a person, he should have known.
"No, demon isn't the right word," The boy said. "Devils?"
"Who are you?" Serafall asked. "How did you get here?"
The boy looked up at the sky. "I think I was in a fight…and then I fell through the sky. I think the hydra followed me through." He looked around and saw the destruction. "I apologize, I didn't mean to cause so much destruction."
"It's okay," Sirzechs said. "It was understandable under the circumstances."
"You're surprisingly kind hearted," The boy said. "I have heard that Devils are much more…devilish."
Sirzechs laughed. "Well not all of us are like that."
"I see," He replied. What was it with him. His responses were genuine, however there seemed to be no life in his eyes. It was as though he had been through a life time of pain and his heart was closed off.
"Would you tell us your name?" Sirzechs asked.
The boy looked up at them. "My name? It's Masamune. Asa Masamune."
"Masamune-Kun," Serafall said. "How were you able to defeat the hydra so easily?"
"That?" Masamune asked. "It's because I'm a Godslayer."
Sirzechs' eyes were wide as saucers. "A…A godslayer?"
Masamune nodded. "I think the title they gave me back then was…Campione?"
Sirzechs gulped.
Author's Note - I recently rewatched Campione and felt like writing a story on it. It's inspired by Campione but only in the terminology so no characters will appear from the original show, which is why it's not a crossover. The beginning is also set before the original DxD story so I'm kind of coming up with the plot as I go. I hope you guys like my little impulsive story :)
