Prologue

Demon World...

"Lord Camio! This is bad! Another tribe has fallen!" A black humanoid looking bird reported to Camio, who was reading some reports inside a tent.

Camio slammed his fist on the table, "Shit! Shit! Shit!"

Camio wasn't one to curse, but the situation is already so out of hand and dozens of tribe has already fallen. Demon World wasn't weak, but due to the shortage of Demonic Force, they are getting weaker and weaker.

Even with the current war with these beings known as Youkais, the Demonic Force just wasn't enough.

The war has only begun for a few days and they are already on the losing side. Not to mention the disappearance of the King, three of the Generals has already fallen and the last one went with the king.

Right now, there are less than ten General level Demons left in the Demon World, and its not enough. One of them, Cerberus, is a stubborn hound that won't leave the King's castle.

Though Camio can be rest assured that the castle will be safe with her there.

"Sir! Bad news! A large group of Youkais are marching in our positions currently! There are around 10 thousand of them! According to the scouts three are about as strong as a Demon General!"

"What?!" Camio exclaimed, the other Bird Demons with him also let out a shocked voice, "....Approximate time before they arrive?"

"Around an hour sir!"

Camio clenched his fist(wings?), "That won't be enough time for us to retreat. We only have 3 throusand Demons here and two Demon General level demons here including me. We will be annihilated."

Not to mention that due to the lack of Demonic Force, they are incredibly weakened and their Magic are very limited since it took a lot of time to recover.

"What should we do uncle?"

Camio turned his head and saw a young woman entering the tent. She has a large breasts and her most noticeable feature being the two large gold-looking horns protruding from the sides of her head and pointing upwards.

A long dark purple hair, white skin and wearing a very revealing blue-colored leopard-printed kimono, bearing the decorative marks on her shoulders.

The kimono is wrapped around her torso with a thick, decorative yellow ribbon that ties behind her back, and her outfit is complemented by thigh-high socks that reveal her heels and toes.

"Seilah." Camio greeted her.

Seilah is a Demon with a strength comparable to a Demon General, and she's also the daughter of Demon General Adremelech from the Ashen Horn tribe with a now deceased female Harpy.

"Uncle should go to the Other World and call his majesty King Satan back. As long as he's here, we will win."

Camio sighed, he was about to speak when he was interrupted by a thunderous explosion.

BOOM!

"What's that?!" He stood up from his seat and walked out of the tent, he was followed by Seilah and other demons.

Once they are outside, they were shocked to see hundreds of dead demons on the ground, and several hundreds of them being injured.

And there, floating above the center of their camp, is an old man with monkey features. Having brown fur that covers his whole body leaving only his chest.

He also has a brown monkey tail and is holding a staff.

The monkey turned his head to face Camio and the others before pointing his staff at Camio.

"Extend."

Camio's eyes widened before he quickly reacted and tilted his body to the side, just in time for the staff to extend and passed by him, but it hit the demons behind him, killing them instantly.

Camio's eyes burned in fury as he turned towards the monkey, only for his pupils to shrink when the Monkey was now standing in front of him.

Before the monkey could make a move, Seilah appeared behind him, now holding a massive axe as she swung it towards the monkey.

However, the monkey moved and blocked it with his staff, though he was blown away with force of the attack.

The monkey balanced himself in mid-air, he then threw his staff to the ground before he landed and stood on it, his tail swaying behind him.

"Who are you..." Camio asked, glaring at the monkey, as Seilah just rested her enormous axe on her shoulder and stared at the monkey with a stoic look.

The axe she was holding belongs to her father, Demon General Adremelech, it is an ancient artifact that belongs to their tribe, and is said to have been gifted to them by the Demon God they worshipped.

"Sun Mori." The monkey introduced himself, "And it would be easier if you surrendered yourself. I admit that your world is the most difficult to conquer since we started invading worlds, but it won't be long before you fall. All can only obey our Demon King."

"Demon...King?" Camio muttered in shocked.

Seilah's eye twitched in annoyance. Though she may not be as fanatic as the Hellhounds, she still adore their King so much that she'll kill herself with a smile if he so ordered it.

"Excuse me but..." Seilah began as her demonic force leak out of her body, and Sun Mori and Camio looked at her, "....What the fuck did you say?"

Sun Mori frowned, "Surrender. You may be strong, but still you are no match for our Demon King, for he and his generals has already Ascended."

'Ascended?' Camio wondered, he knew the meaning of the word, but he doesn't know what did Mori mean by his words that the so-called demon king and his generals has already ascended.

Seilah took a deep breath. She's normally a very passive and stoic person who'll only stay and watch at the sidelines, but this man in front of her has just touched her "reverse scale" so to speak.

"Here's my answer...." She glared at Mori and appeared behind him, swinging her axe, "...Go fuck yourself!"

Mori's eyes widened and he quickly moved and pulled his staff to block it, this time his staff extended and stabbed to the ground, so he wasn't blown away by the force of Seilah's attack.

Camio stared at them for awhile before he snapped out his daze and ordered the other demons, "You guys! Carry the injured and retreat! There are still a group of 10 thousand Youkais marching here! Hurry!"

"Yes sir!"

"Affirmative!"

"Right away sir!"

Seilah ignored those and send a kick to Mori, and then a punch, and kick, elbow, before swinging her axe once again.

Mori evaded those, but not easily. He did not bother blocking because he knew it will surely hurt.

He glared at Seilah who continued on Attacking as he pointed his staff st her, "Extend!"

Seilah calmly twisted her body and dodged it before she moved and appeared behind him, before swinging her axe.

Mori retracted his staff before he flip backwards and retreated a good ten meters away from her.

He glared at her, "I'm tired of this."

"Grow." Immediately, the staff expanded and turned into a large pillar before extending towards Seilah.

The demon's eyes widened, she wouldn't be able to dodge this.

It was that moment that Camio appeared, he kicked Seilah away before using all of his Demonic Force to strengthen his body and blocked the pillar-like staff.

"Impressive." Mori nodded before he retracted the staff back, "But how about this."

He raised his hand as dark clouds gathered above them, roars of thunder were heard as Mori's spirit power bursts out of his body, completely suppressing Camio and Seilah.

"Here I come."

Camio turned his gaze towards Seilah, "Go Seilah! Leave this place to me! Go with the others and make sure they survive! I'll hold him off!"

Seilah just stared at him in shock for a moment before she shook her head as her face became expressionless and nodded. She wanted to help, but she knew they also needed to make sure that the other demons doesn't go and get annihilated.

She glared at Mori before leaving. She knew that if they decided to fight the monkey, they might win, but there are still the ten thousand Youkais marching towards this place.

Killing the monkey will surely take a lot of time, and during that time, the Youkais will surely arrive and they will die.

She stared at Camio one last time before nodding. This man raised her since she was young, she treated him like a second father, and she knew that he may not be able to see him again.

Camio sighed in relief as he watched her leave and glared at Mori, "Though I may not be King Satan's match anymore, I was still once his teacher. Bring it on! I'll tear you apart."

Though he knew it himself that he'll probably die.
