Reborn: Ulquiorra In DxD World

"Eh?! Eeeeeh?!" Serafall cried out. Ulquiorra was standing beside her with a plain expression.

Sirzechs and Azazel smile wryly at her antics. Suddenly the purple orb in short golden spear emitted a light in Azazel's hand. Both Azazel and Sirzechs looked up.

"Oh? I didn't think you'd come here yourself." Azazel said.

Im the mid air up above them a girl in gothic outfit was seemingly sitting in the air. The girl have a long black hair down to her h.i.p.s and black eyes. The girl was none other than the leader of the Khaos Brigade, Ophis.

"Azazel. It has been a while." said Ophis while looking at them. She slowly descend at arrived in front of them.

"Ophis?" Serafall said in a low voice. She and Ulquiorra flew and arrived beside Azazel and Sirzechs.

'Ophis, one of the most powerful existence.' Ulquiorra thought while observing Ophis.

"If we defeat you here, will peace be finally achieved?" Azazel said while pointing the short golden spear at the Ophis.

"Impossible. You cannot defeat me." Ophis replied.

"Though you have immense power, you show no existence in the world." Azazel said.

"So why are you leading a brigade of terrorists now?" Sirzechs asked.

Ophis turned her head and looked in the sky, "A world of silence. I would like to return to the Dimensional Gap that is my home and reclaim that silence. That is all."

'The Dimensional Gap, huh? If I remember correctly... ' Azazel thought and he raised an eyebrow, 'I see, Vali. I know what you want!'.

'World of Silence' Ulquiorra muttered in a low voice.

Ophis noticed Ulquiorra. She looked at him and said, "A soul? No, something's different about him. It's my first time seeing an existence like you in this world. It's hard to distinguish that parts of you became a devil."

'First time in this world? Me? It seems my guess is true' Ulquiorra thought.

Suddenly they felt a burst of energy. The energy was so powerful that they could clearly felt the danger on it.

All of them turned their heads and looked at the direction where they sense the energy.

"Draconic aura?" Azazel frown as he said. "Don't tell me something happen to Issei... "

"Hmm? Something's happening to Red Dragon there" Serafall said.

Ulquiorra just looked at the direction. He clearly remembers when he left he saw Issei was beating his opponent easily. And his opponent was pretty weak.

They noticed that Ophis was already gone.

"Let's go, let's take a look" Azazel said.

"Go help him, I need to stabilize the situation here." Sirzechs said.

Azazel nodded and left with Serafall and Ulquiorra.

...

They saw Issei was rampaging in his juggernaut drive form. He really lose control of himself this time. He was firing a laser to everything he saw. They also saw Vali, Bikou, and Arthur was standing beside Rias group. Azazel went back and find Irina cause Odin gave Irina some item that will help. Irina came back will a speaker and she play Issei's Bood Dragon song. When they saw Issei was reacting Vali took this chance to weaken Issei. He use juggernaut drive. And after that it's Rias turn to wake Issei.

In the end they finally manage to wake Issei. The first thing he asked when he woke up was Asia. He sighed in relief when he heard that Asia was alive.

"Watch carefully, Hyoudo Issei." Vali said as he looked into the sky.

Issei looked in the sky and his eyes opened widely when he saw a huge red dragon appeared in the sky.

"That's what I came to see" said Vali while looking at the massive red dragon.

"What is that?" Issei asked.

"Dragon of Apocalypse, Great Red. It's also called true dragon, dragon of dragons." Vali replied. "I want to defeat him and become the white dragon god."

Ulquiorra also examined the Great red. 'Dimensional Gap? I think I have an idea of what really happened'

Everything turned out fine after the battle. The two descendant of the original devil died in battle or so they thought.

...

After a day everyone went back to human world. Ulquiorra also went to the human world. Everyone was back to school and they we're planning about their school trip. The first and second year will go to kyoto for their school trip. Rias, Sona, and others were third and they wouldn't be able to join them.

Sona walked beside Ulquiorra. She glanced at him and said, "Asia told me that you were there..."

Ulquiorra glance at her and nodded.

Sona wanted to asked why he didn't save her that time. If he save Asia that time Issei wouldn't turned like that. But when she heard what Asia told her she held back her question. Asia didn't tell anyone about this except her.

'Are you afraid? That's the question he asked to Asia.' Sona thought. She turned her head to him and looked at him deeply before she turned around and left.

'What are you thinking, Ulquiorra?' her thought as she walked out of the room.

...

Three days have passed since the old satan faction attack the underworld. Everything was fine and there's sign that Khaos Brigade will attack again.

A blue magic circle appeared behind Ulquiorra. Vali walked out of it and stood beside Ulquiorra.

"There's someone in the Khaos Brigade that probably have an information that you want." After a few seconds Vali said.

"Who?" Ulquiorra asked. He kept looking ahead and didn't even glance at Vali.

"Euclid Lucifuge... " Vali pause for a few seconds before he added, "And Rizevim Livan Lucifer, my grandfather."
