Reborn: Ulquiorra In DxD World

Inside a room there's a round table in the center. Four people were sitting around the table. They are the leaders of the three faction. Michael, leader of the Angels, Azazel, governor of the Fallen Angels, Sirzechs and Serafall, the Satans.

A girl named Irina was standing behind Michael. Vali was behind Azazel. Rias and her peerage was behind Sirzechs while Ulquiorra, Sona, and Tsubaki were standing behind Serafall.

An army of Fallen Angels, Angels, and Devils were outside the building. They were looking at each other incase something bad happens. They were ready to launch an attack if someone makes a wrong move.

The atmosphere of the room was heavy. Everyone was tense and had a serious expression.

"So, this is the one who took care of Kokabiel." Azazel looked at Ulquiorra with interest.

"Ahem!!" Sirzechs fake his cough gaining the attention of everyone.

"Allow me to introduce them." Sirzechs started after he gained the attention of the leaders.

"This is my sister and her family. They did very well in their recent battle with Kokabiel."

"Thank you everyone and you too Ulquiorra we appreciate your efforts." Michael said.

Rias stepped forward and started to tell the details of the battle against Kokabiel. Sona testify their speech.

"I'd like to hear the General of the Fallen Angels' opinion on Rias' report." Sirzechs said.

"There's nothing much to say. Kokabiel acted of his own accord." Azazel replied.

"It has nothing to do with you" Michael said.

"I was waiting for what has he up to," Azazel smirked.

"Well, enough small talk. Let's sign that peace treaty already." Azazel said as he looked at Sirzechs.

"The one who start the war, God and the Satans, are gone, after all." Michael said.

"That's why we have the two here, although not part of our stand-off, but have the power to change the world." Azazel as he crossed his arms.

Issei and Vali became the center of discussion. Vali expressed his d.e.s.i.r.e that he only want to fight a powerful opponent. Issei too expressed his d.e.s.i.r.e that he want peace.

The conference continued. Everyone seems in a good mood. At some point of the conference Issei asked Michael why Asia was exiled. Michael explained everything to Issei why he do that.

Suddenly they felt something change in the atmosphere.

"What the..." Issei was shocked. He turned around and saw Sona and Tsubaki standing there motionless.

"Did someone... stop time?" Kiba muttered.

"Looks like it. We weren't affeted due to our immense power." Azazel nodded.

The ones who are affected were Asia, Akeno, Sona, and Tsubaki. The others weren't affected due to their immense power or they were protected because of their sacred gear and holy swords.

Ulquiorra went in front of Sona. He looked at her motionless body.

Boom!!

They heard a loud explosion as the building they were in shake.

Issei and others walked to the window and saw a group of mages appearing in the air.

"Hey! I'm the magical girl here" Serafall complained.

Azazel said that the one who was causing the time to stop is Gasper. Gasper must be in the enemy's hands if it's like that. Rias and Issei proposed to go and rescue Gasper and Koneko.

"Serafall-sama do you want me to-" Ulquiorra walked beside Serafall and said.

"No, Ulqi-tan just stay here and protect So-tan" Serafall said.

Azazel let Vali go out and greet the enemy outside. Vali flew outside and immediately used balance breaker. The mages quickly launch an attack at Vali. Vali just floated in the air as the attack could do notjing to him. He then opened his palm and a magic power gathered in it forming a white ball.

He threw it at the mages immediately destroying their formation.

Suddenly a magic circle appeared behind them. All of them turned their heads and saw a bespectacled woman appeared.

"Good day, Satans Sirzechs and Serafall." the woman greeted the two.

"W-What are you doing here?" Serafall was shocked when she saw the woman.

"The descendant of the previous Leviathan, Katerea Leviathan?!" Sirzechs was also surprised.

"Chaos and ruin to the world... " Katarea raised up her wand in the air.

Ulquiorra felt something bad. He immediately used sonido and appeared in front of Katerea. He pulled back his arm and shot a powerful punch.

Boom!!

The building exploded. The explosion disintegrated the whole building. Smoke and dust filled the surrounding area.

"Cough! Who are you?" Katerea coughed. She looked at Ulquiorra and asked while frowning. She looks in mess right now. Blood drip down from her mouth. She clearly felt Ulquiorra's punch just now, coupled by her magic that exploded in front of them.

Ulquiorra looked at her as he slowly put his hand to his sword. His clothes was in tottered and his c.h.e.s.t was opened for everyone to see. They could see his hole and the tattoo.

"Ulquiorra!" Serafall exclaimed.

The leaders looked at Ulquiorra. They put a barrier around to protect the rest from the explosion. They didn't expect Ulquiorra to react that fast and counter Katerea. Unfortunately it still caused an explosion.

Sirzechs turned his head to Katerea and asked, "What are you trying to achieve, Katerea?"

"To do exactly what this conference sought not to do." Katerea replied. "If God and Satans are gone, then this world will be ready for evolution."

"Stop this, Katerea-chan" Serafall tried to persuade her. "Why are you... "

"Serafall... " Katerea gritted her teeth. "You are the one that stole the position of Leviathan from me!"

"I... "

"Don't worry, I'll kill you right here, right now, and take back the title Satan Leviathan from you." Katerea slowly descend from the air.

"Then, allow me to kill you." Ulquiorra said as he lifted up his arm and pointed his finger at Katerea. A green ball spinning like a razor form on the tip of his finger. It expanded a few time before it grew smaller.

"What is this feeling?" Azazel said looking at Ulquiorra. They didn't know that they were feeling Ulquiorra's spiritual pressure right now. It was gushing out of his body pressuring Katerea.

The green cero reached the peak of it's strength. With a boom it shot a massive beam towards Katarea.

"Gran Rey Cero!
