Calcio and Key's Disciple

There are twenty-three dukes, thirty-three Marquises, forty-seven Counts, sixty-six Viscounts, and 666 Barons inside Hell. 

The rift is inside Prince Calcio's Domain. Matthias flew directly above his domain, towards the rift, which shows his nonchalance against Calcio, which enraged the generals and underlings of the Demon Prince.

A fleet of winged Demons flew and prevented Matthias from moving further, "Stop right there! How dare you fly directly above the Prince of The Abyss' Domain?!" The demon at the front shouted.

Below, an army of demons were also lined up to take him down. Matthias narrowed his eyes and spoke coldly, "Leave me alone, and I won't do anything bad." 

"Ha! What can you even do, weak human demon!" The demons laughed.

"Calcio! Make these ass-licking demons get out of my way or I'll wipe them out!" Matthias shouted.

"How dare you!" By now, the demons were extremely enraged. They angled their wings and rushed towards him. The demons below casted flames and threw the flaming balls towards him.

"Sigh. Naive demons." Matthias shook his head. He then raised his hand and swiped all of the attacks away.

"Voom!" A huge pressure descended towards the attackers, then they were launched backwards.

The fireballs that were launched stopped and started falling in Calcio's territory, destroying some of the structures.

"No!" The demons went weak. Suddenly, an averagely built demon that didn't really look like a demon at all floated towards him. He has a pale white skin, four long black horns, and sharp red pupil eyes. His hair that was combed back made him look respectable and with his long black coat that was waving as he floated, he looked like a very respectable Demon Prince.

The Demon, Calcio, stopped in front of Matthias. Then, he knelt, "Greetings, Lord Madios Vilfrein."

Matthias' eyes bulged and looked at Calcio with shock, "How did you know my Prince Title in the Mysterious Abyss?"

"I am from the Mysterious Abyss." Calcio answered.

Matthias scrutinized him and was astonished when he discovered something, "You.. You're a Divine Demon? What are you doing here?"

Calcio stood up and answered his question, "A huge war broke out inside the Mysterious Abyss. The big Demon Empires have now fallen due to the large-scale rebellion that was led by Duke Senatio of the Central Blazing Domain."

"Hmm, Senatio, I'm familiar. What is the state of the Abyss now?" He asked.

"Currently, from my known scope, the empires of Tanki, Servantos, Vilfren, and Sigin have fallen. Vilfrein is currently the most stable of the domains as the territory was already ruled by the Dukes below you centuries before the rebellion. But the Absolute Monarchical Territories of Servantos and Sigin are in a total mess. Countless Dukes warred against each other and there's even internal conflicts inside their dukedoms." Calcio answered.

"Now that is messy." Matthias gulped. "Then why are you here?"

"Divine Demons were recruited en masse when the war started. As a result, us Divine Demons that don't want to be in the open, retreated and hid across all the domains. I got lost and was dragged by the rift someplace. Then, I served a master but he died. He was a great master as he is intelligent and also doesn't like to be in the open, like us." Calcio answered and reminisced.

"Wait." Matthias noticed something, "Did you just say you served someone?" 

"Yes?"

"What's the name of your master?"

"Unfortunately, I cannot divulge his name to you, Lord."

"Hmm, loyal. But.." Matthias paused, "Did you serve that master with the name of Alvantos?"

This time, Calcio's eyes were the one that bulged, "That is my serving name."

"Goddamnit, you're here!" Matthias chirped. "Come with me!" He opened a portal and entered with a dumbfounded Calcio.

They appeared in a secluded corner and they settled. Matthias removed the portal and looked at Calcio. He waved his hand and Calcio became covered with invisibility. 

It was still night on Earth, so the corners were extremely dark. Matthias took advantage of it by hiding in the darkness. 

He walked to Key's house and opened the door. The two families were still there. Stacy looked at him weirdly and asked, "You forgot something?" 

"Nah, I cancelled it." Matthias chuckled and walked upstairs while the five people below looked at him.

"I really think that what Key proposed is true." Amy, Jeremy's mother, spoke.

"Right?!" Key replied. Stacy once again slapped his head.

Back to Matthias, he walked to his room and he saw Jeremy was still there. "You're back? What happened?"

"Found him. Calcio?" Matthias called.

The shroud was removed and the figure of Calcio was shown. "Master Jeremiah?!"

"Alvantos!" Jeremy gasped. Calcio, or Alvantos, knelt and paid respect to him, "Greetings, Master! I'm sorry that this butler of yours failed to protect you in the war!"

"You need not be sorry, Alvantos. Saragon was too strong of an opponent. I think Kreis solved it. He did, right, Matthias?" Jeremy replied.

"Yes. Elegantly. Wait for me here. Talk to each other first." Matthias nodded and vanished.

Inside his Domain, he flew towards the Earth he created. He turned invisible and entered the World Core.

Inside the center of the Earth was a gigantic round cave. In the middle was a huge glowing orange orb. It was brimming with energy and was chained by a lot of metal brought from Alphan.

"That girl did the work." Matthias nodded as he remembered the woman that came back to Earth. Within his evaluation, she was a very talented woman, being able to control the Laws of Chaos professionally.

Matthias raised his hand horizontally towards the core and started extracting qi from it. Suddenly..

"Who are you?" A long blade was placed on his neck. A voice of a woman sounded behind him.

"Woah there, sweetie. You would want to put that down." Matthias didn't even flinch and continued to extract qi from the core. He didn't turn around to answer her and instead continued to extract.

"Stop what you're doing, now." The woman ordered coldly.

"Alright, I'm already finished anyways." He chuckled and raised his hand. A tennis ball-sized light orb was on his hand. The woman noticed something and gasped. She yelled, "That's Lord Jeremiah's Qi Core! Return it!" 

"Oh? You know Jeremy? Who is he to you?" Matthias looked intrigued.

"He was my master's friend. One of the most powerful elites of Earth! Return it to the Core!" She yelled.

"Oh? You're Key's disciple? How is that even possible?" Matthias gasped and laughed. He turned around and was stunned with what he saw.
