Reborn: Ulquiorra In DxD World

Khaos Brigade was slowly crumbling inside. Now that the Old Satan faction was gone the only one left are Team Vali, Hero faction, Magician faction Nilrem, and Qlippoth. The Hero faction don't care about others as they have an unknown backing. Qlippoth and Magician faction were allies because the leader of the Magician faction Nilrem is a Lucifuge. In ancient times the Lucifuge clan swore an utmost loyalty to Lucifer. And as the heir of the clan, Euclid serve Rizevim as the latter was son of Lucifer. These two group will break out the power balance inside the Khaos Brigade.

"Euclid Lucifuge, is the brother of Grayfia Lucifuge, Sirzechs wife. He is also the one who brought the information about Rizevim." Vali said. "Those two were very powerful it's not easy to talk to them if you met them. Even I don't know much about their power, only I know is that the two of them were extremely powerful. Fortunately Rizevim wasn't interested in Underworld or else he already attack it long time ago."

Vali glance at Ulquiorra and saw that he was listening. He continue, "Those two were hard to find. They are doing some shady things behind our back. If you want to find them it's not easy to do it. Well, Ophis already lose her powers inside the Khaos Brigade and the Hero faction was planning something."

"Okay, I've said what you want, I'm gonna leave" Vali said before he turned around. After walking a few steps Vali stopped. He turned his head and said, "I forgot something, I've heard a rumor that Shalba is still alive. Tell Hyoudo Issei to be careful as he is likely to become target by Shalba if he was really alive. Also don't forget what you said to me."

After Vali said that he immediately left.

After a few moments a garganta opened in front of Ulquiorra. He stepped inside and went to the Underworld.

...

"I see, so there's an information about another world but we're still not sure if this is true." Serafall nodded. In front of her was Ulquiorra who ask her permission to investigate it in human world.

Serafall looked at Ulquiorra and said seriously, "I'll allow you but don't do anything rush."

"I know, I will be careful" Ulquiorra replied.

"You should do that your heading to one of the enemies headquarters." Serafall said.

Serafall didn't asked many question about Ulquiorra. It's rare for him to asked something so she let him do what he wants but before he go back to human world he needed to accompany her in her magical girl ultimate spiral entrance training.

...

Ulquiorra return back to human world. He was greeted by Sona when he arrived.

"How is Onee-sana?" Sona asked.

"It's okay, she's still the same as usual." Ulquiorra replied.

"Hmm... " Sona hummed. "Say Ulquiorra, How did you and Onee-sana met each other?" She didn't know what to say so she just asked this question even though she already it from her sister.

"I died, I do not know how I came here in Underworld. Serafall-sama found me as I was dissipating in the air. She reincarnated me into a devil." Ulquiorra said to her.

"Then, H-How did you die?" Sona hesitated at first when she asked.

"A man named Kurosaki Ichigo defeated me." Ulquiorra said.

"Kurosaki Ichigo?" Sona had no idea who it is.

"He's a biproduct of human and hollow. Even I can't believe that I lose to someone like him." Ulquiorra said, "He with his friends went to Hueco Mundo and invade Las Noches to save a woman. Lord Aizen took the three highest Espada with him to human world because they were going to fight a war against Shinigami. As the highest ranking Espada left in Las Noches, Lord Aizen entrusted me the Las Noches. At first they were quite weak but after many battles against Arrancar and Espada they grew stronger. In the end Kurosaki Ichigo defeated me and rescue his friend."

Ulquiorra glance at Sona.

Sona was in dazed. Her mind were processing the information she received.

'Kurasaki Ichigo that man must strong for him to defeat Ulquiorra' Sona thought. She also feels that Ulquiorra and his group were like a villain from what she heard from him. Well, it's true that a shinigami were going to kill them if they met because they devour souls.

And Lord Aizen. This man was powerful enough to control all the Espada. He also created them and most importantly how did Ulquiorra met him.

Sona looked at Ulquiorra and asked, "How did you met Aizen?"

Ulquiorra turned his head and looked at her face.

Sona looked at him in the eyes seriously.

...

A few days later the school trip start. Rias and Sona bid farewell to their peerage member who were going to Kyoto. They gave them some sort of pass for them to freely explore the Kyoto. If they didn't have this the supernatural of Kyoto wouldn't let them enter their territory.

Only Rias and Akeno were left to handle the town and Sona with Tsubaki to academy.
