Xenoverse Arc

Chapter 1: The Return of the Eternal Destroyer God

Back in ancient times, there was once the most powerfulest Primordial that was ever born out of nothing. This being was known as the Almighty Kami. And after years of his existence, another powerful primordial was born from nothing. This primordial was named Chaos and boy was she a handful.

The goddess chaos was a pure-hearted primordial with impure thoughts, only wanting to cause nothing but endless destruction. The Almighty and Chaos fell in love as they eventually had children such as Azura; the Holy Spirit, Jaakuna; The Personification of Pure Evil and Destruction, and the new heir to the throne, the Omni-King, Zeno. Jaakuna was furious and jealous of his younger brother for being the heir to the throne, so he stood up against his father and declared war against him.

The Almighty Kami and his Son, Jaakuna, fought for at least a century in space as the Almighty finally had enough and sealed his Son in a Diamond-Shape Prison as Jaakuna was chained up inside. The Almighty threw the diamond-Prison into a realm similar to the null realm. After millennials of centuries, Jaakuna finally broke free of his prison as he also destroyed the entire realm he was trapped in.

Space

"My, my, my~ it seems I've been finally set free!" Jaakuna said cheerfully. "Hehehe. Hahaha! Mwahahahahaha!! Yes! I'm finally free from that pathetic prison! And now it's time to exact my revenge against Father!"

Jaakuna flew in space as he headed towards the Omni-Kings Palace. The old home he grew up in. And with astounding speed of flight, he reached the palace in 10 minutes tops. Jaakuna stands up straight as he looks at the palace.

"It seems this place hasn't changed at all! It still looks the same before I fought father." Jaakuna said before walking into the palace.

The Grand Priest felt his very core tremble in fear as he felt Jaakuna's Evil and Demonic Aura.

(I-It Can't be!!... What is a Demon this Powerful doing here?! How did he find us and so quickly!?) The Grand Priest Thought with the expression of fear on his face. (I must send the guards the stop him at once! He will not get to the Omni-Kings!!)

"What's wrong, Grand Priest?" The Zeno's asked him.

"it's n-nothing my lords! Please. Do not worry. I'm quite alright." The Grand Priest said as he looked at the guards and nodded his head at them.

The guards got the message of his head shake and left the room as they went out to stop Jaakuna. The Grand Priest has suddenly gotten jump-scared as he heard the guards scream out in pain. Thankfully, the Zeno's didn't hear the screams.

The Grand Priest summoned his staff and quickly looked into it as he saw Jaakuna ripping the guards apart with ease. The Grand Priest suddenly became scared of the demon's presence as Jaakuna suddenly disappeared within view of the staff. The Grand Priest tried to make connection to see what's going on until he felt shivers down his spine. His instincts were telling to quickly get away and protect the Omni-Kings.

The Grand Priest quickly turned around as he jumped back and saw Jaakuna with his arms crossed and with a devilish smirk on his face. The Grand Priest has given off a Afraid facial expression as the Omni-Kings were surprised to see Jaakuna in the room.

"Well Hello there. I certainly remember seeing you before. Do tell me. Who the Hell are you?" Jaakuna asked with a serious facial expression, scaring the Grand Priest.

"I...I am the Grand Priest, the Guardian and Protector of the Omni-Kings. I am the father of all Angels." The Grand Priest managed to say. "Who are you?! You are no ordinary demon from the looks of it And how the heck did you managed to find us here?!"

"The names Jaakuna Kami, little brother and shouldn't that be obvious? I lived here way before you even came into the picture." Jaakuna said in confidence. "Though, I wouldn't be surprised if you didn't remember me. Heh~"

"What do you possibly mean by that?!" The Grand Priest asked him.

"We were all created by two powerful entities known as the Almighty Kami and The goddess Chaos! Our older brother, Azura, was first. I, am the second son. And those two you're trying to protect, are the third children of our father!" Jaakuna said. "That being said, it seems like you're the fourth child as you claim to be the father of all angels. I'm here to take back what's mine!"

the grand priest immediately transformed formed into his Transcended Angel Form (Relating to Unrealentgaming's Grand Priest True Form) as he said to the Omni-Kings; "Stay behind me, you two! I will protect you at all cost from this demon!!"

in a single moment, Jaakuna guts punches the Grand Priest as the Grand Priest reverted back to his original appearance and fell onto his knees as coughs out blood and saliva.

"Just one punch was good enough to bring you down to your knees. I'm very disappointed." Jaakuna said before he raised his right hand makes a fist.

Red aura-like chains suddenly appeared and chained up onto the Grand Priest as well as the two Zenos. Jaakuna snapped his fingers as the corpses of the guards appeared beside Jaakuna and transformed into two powerful demonic entities.

"Wh-What did you do to them!?" The grand priest demanded.

"I turned them into my trustworthy Demon God Guards!" Jaakuna said cheerfully. "And now, you three will be my prisoners! Take them away, boys!"

The demon god guards took the three of them into the dungeons Jaakuna created as Jaakuna sat down on the Omni-Kings Throne.

"Ahhh~ It feels nice to finally be the king of all! I finally achieved what I truly deserve!" Haskins said all relaxed. "Now then. Let me summon the evil entities that rule this world now~"

Jaakuna summoned Mechikabura, Demigra, Mira & Towa, and Fuu, all in front of him as they all surprised to see one another and to see Jaakuna sitting in the throne in front of them.

"Who the hell are you!? Are you the one who summoned all of us here?!" Mechikabura asked angrily.

"Why yes~ yes I am! Allow me to introduce myself. I am Jaakuna Kami, the Personification of Evil itself." He said. "I summoned you all here because I am in need of help and In need of followers. That said, I have a proposal for all of you~"

"Proposal?" They all questioned in unison.

Jaakuna turned to Mechikabura. "You old man, I can return you to your youth and grant you a great amount of power far than your previous youths power."

Jaakuna turned to Demigra. "You're Demigra, yes? I shall grant you the power of your dark king as well as powers far beyond its strength."

Jaakuna turned to Mira. "I can grant you powers beyond your wildest dreams that can slaughter any of your opponents."

Jaakuna turned to Towa and Fuu. "As for you Two, I can grant powers far beyond your imagination so you continue on with your research."

"But this is all in exchange for your loyalty and trust. Do we have a deal?" he said to them all.

They all nodded their heads yes as Jaakuna smiled excitedly and said; "Perfect! Before I grant you all your desires and new powers, I want you all to recruit new members of evil to serve under me. The more allied we have, the less time we have to conquer this entire multiverse! Understand?"

They all nodded their heads as Jaakuna grants them all new powers and returned Mechikabura back to his youthful appearance.

They all bowed down and said in unison: "All hail Lord Jaakuna!".

"Good! Good. Let's get this invasion started shall we?" Jaakuna said. "The faster we start recruiting new members, the faster I can start this war!~"
