System In Another World

"Let me, Sirzechs," Azazel said as he stepped forward.

Sirzechs nodded at him. They ignored Jin who has an excited expression. If he's not their enemy then they will not bother him. They don't want to make another enemy. After all, the three factions don't want another war or fight a strong enemy.

Even though Sirzechs and Ajuka were in the top strongest in the world they were still afraid to go to war. The Great War before reduced their population to a large margin to the point that they need to reincarnate humans into a devil. Even if they were powerful they couldn't protect every devil in the underworld. If another war happened they don't know how many devils would survive. That's why they don't want a war and wouldn't easily fight someone.

Jin talked to Serafall beside him while Azazel was fighting Katarea. The battle between the two was terrific and Sirzechs and Michael need to used barriers to protect everyone.

Issei and Rias went out to rescue Koneko and Gasper. After all, the two were still in the hands of the enemies.

Vali who was fighting the group of magicians glanced at Jin. He was wondering why Jin was here and was happily talking to Leviathan.

He shook his head and continued fighting the group of magicians. He created a ball of energy in both of his palms and threw it towards the magicians.

Boom!! Boom!! Boom!!

At this point of time, the fight between Azazel and Katarea reached the climax. Katarea was forced to use the snake from Ophis.

"Snake...?" Azazel frowned when he saw this.

"Die!!" Katarea pointed her staff at him and burst out energy shot towards Azazel.

Swooosh!!

Azazel disappeared and reappeared behind Katarea. He opened his mouth and said, "Before we continue this. I want to ask some questions."

Katarea coated her hand with her magical power and swung it at Azazel.

Bang!

Azazel blocked it with his hand and he asked who's backing Katarea for her aura wasn't something that a descendant of Satan could have.

Katarea just laughed it off and used her enormous magical power to create a huge explosion.

Boom!!

She then looked up and saw Azazel up above her looking down on her. She flew up at his level and looked at him.

...

Jin was talking to Serafall when he felt that the time started ticking. He turned his head and saw that Rias and Issei managed to rescue Koneko and Gasper.

Akeno, Sona, Tsubaki, and the rest which was frozen returned back to normal. They have a look of bewilderment in their face when they saw everything around them.

"Welcome back, So-tan!" Serafall flew and hugged Sona.

"O-onee-sama!!" Sona was surprised as she doesn't have any idea what's happening to them.

Rias stepped forward and explained to them what's happening and they proposed to fight which Sirzechs approved.

"Hoo~" Jin grinned and he turned his head to Azazel and Katarea.

Azazel took out something. It was a small spear with a black orb at its handle.

"What's that?!" Katarea frowned as she gripped her staff tightly.

"This the downfall dragon spear. An artificial sacred gear." Azazel smiled and said, "Balance break..."

A golden armor with purple jewels covered Azazel's whole body. In his hand was a two-pronged spear of light.

"Downfall dragon another armor."

Azazel raised his hand and taunted Katarea. "Come on!"

Azazel and Katarea clashed.

Boom!!

In just a single blow, Azazel managed to injured Katarea.

Katarea saw that Jin was talking with Serafall. Her anger flew up when she saw this.

"You!! Why are you talking to her? She's an enemy! That fake Satan is an enemy! Kill her! I'm ordering you! Kill her!" Katarea shouted loudly while pointing her finger at Serafall.

Sirzechs, Azazel, Michael, and the rest quickly turned to look at Jin warily. Up until now, they still weren't sure if Jin was their enemy or not.

Even Vali stopped just to looked at Jin. He grinned while wondering what Jin would do in this kind of situation.

"Huh? You are..." Jin pointed at Katarea then at himself, "...ordering me?"

"Hahahaha," Jin then laughed loudly. His laughter echoed in the whole area.

"What's funny?" Katarea asked him.

"What's funny? You asking me... Hahaha, it's funny because you think you can order me around even though you're a weakling." Jin replied while laughing. "Even though you're not that close to me you're still ordering me. I only do things for people who I treat as my family."

"You!! How dare you!! You're just a human!!" Katarea's face contorted at his words.

"Hais..." Jin sighed and closed his eyes. He started to float and stopped at the level of Katarea before he opened his eyes. "I've decided I'll kill you now because you've ruined my mood."

Jim then slowly raised his right arm.

Everyone looked at Jin watching his every move.

"I wouldn't even join this group if not for Ophis. You people wouldn't even enter my eyes." Jin's tone changed to a cold one. It was clearly different from before.

"What?!"

"Ophis?!"

Everyone was shocked when they heard the word "Ophis" came out of his mouth. All of them knew Ophis.

"You will die in an instant," Jin's aura flared up to the point that everyone could see it with their own two eyes.

Partial Transformation: Dragon's Arm!!

Jin's right arm bulge out and become a dragon's hand. Glossy black scales and sharp claws.

Everyone was shocked by what they saw. They saw his arm become a dragon arm.

In the next moment, Jin grabbed Katarea and black energy came out of his arm. The black energy swallowed Katarea and when the black energy disappeared Katarea was gone. Everyone could not feel her aura anymore.

In an instant, she died just like that.

"What?!"

"How?!"

Everyone was shocked when they saw him killed Katarea without leaving any trace of her existence.

"What power..." Issei muttered while looking at Jin's back.

"Stay back!" Sirzechs said to Rias, Sona, and the rest of their peerage.

"Dragon?" Michael observed Jin.

Azazel frowned and didn't say anything. He just looked at Jin.

Jin turned his head and looked at them.

"Now, let's move to the current leader of the three factions..."
