Reborn: Ulquiorra In DxD World

It's been a week since Ulquiorra arrived in the human world. He always stay beside Sona and do nothing except observing the students in kuoh academy.

Sona was curious as she always saw him beside the window looking at the people. She remembered back in the Sitri clan he was also observing the servants in the garden. She was curious so she asked him.

"Why are you always looking at them?" Sona stood beside Ulquiorra and asked.

Ulquiorra turned his head and glance at Sona before he turned to looked at the students.

Ulquiorra opened his mouth and said, "I'm just curious about those people"

"Curious?" Sona looked at him and didn't said anything. She didn't get the the answer she want and he only answer vaguely. She doesn't to pry to much so she just closed her mouth beside him. She remember that she doesn't know anything about him except that he was a member of her sister's peerage and that's all.

A moment later Ulquiorra once again opened his mouth, "I'm trying to find someone"

Sona looked at him and didn't say anything.

'Who is he trying to find?' Sona thought.

...

At night after the class is over the rating game between Rias Gremory and Riser Phenex will start.

This rating game caught Ulquiorra's interest so he inquired Sona about it. Sona tell him the details about rating game.

Ulquiorra was currently watching the rating game with Sona and her peerage. There's a huge screen in front of them that displays the rating game between Rias and Riser. This rating game took place inside the kuoh academy and the one who's managing it was Sona.

Ulquiorra looked at the huge screen in front of him. It displays the battle between Rias and Riser.

"That bastard Riser is really strong" Saji said as he gritted his teeth. He was worried about his friend Issei.

"The blood of phenex clan flow through his veins, he's a pure blood devil, so naturally he was born stronger compare to others." Tsubaki said.

Sona glance at them but didn't say anything. She just continue watching the rating game.

Currently the fight was intense as Riser was fighting Rias peerage.

Ulquiorra frown while watching the rating game. Watching Issei used everything he got in order to defeat Riser, even though he couldn't defeat Riser he still fight him.

Ulquiorra couldn't help but say, "I couldn't comprehend it, why does he still fight even though he knew that he couldn't defeat his opponent? Why still going up?"

Ulquiorra looked at Issei who was full of injury still going up.

Sona and Tsubaki looked at Ulquiorra when they heard his words.

"Why? It's because Riser is a sc.u.m. It's better to marry other people but not that guy. That guy will only treat Rias-senpai as a breeding cow only to preserve their pure blood." Saji looked at him and said loudly.

"I see, that is something I couldn't comprehend" Ulquiorra said. He then added in a low voice, "I once met a guy who fight against all odds and a girl who blindy believe in him"

Sona looked at him and adjusted her glasses. Even though Ulquiorra said those words in a low voice she still heard it all.

The rating game concluded when Riser defeated Rias Gremory and her peerage.

The atmosphere in the room turned gloomy. Especially Sona, her expression said that she really hated the result. Rias was her childhood friend. She doesn't want Rias to become a woman of some unworthy guy, especially if Rias didn't love that man. She also had a fiancè but she broke off the engagement after she defeat him in chess, exclaiming that she wouldn't marry anyone who couldn't defeat her in chess.

Looking at the depressed mood of everyone, Sona stood up and said, "First let's restore the damage of the battle."

"Yes, President" Tsubaki and others said.

They immediately left the room and restore the damage caused by the fight in academy.

...

A few days have passed since the rating game between Riser and Rias. Rias went back to the underworld with Riser. Sona and her peerage also went back to underworld as they were inveted in the engagement party of Riser and Rias.

Akeno, Koneko, and the rest of Rias Gremory's peerage were depressed throughout these days. They were blaming themself as they were not strong enough to protect Rias.

Ulquiorra also went back to underworld as he was here only to protect Sona.

As soon as they arrived at the Sitri household, a figure flashed and tackle Sona making her stumbled to the ground. Ulquiorra already knew who was that person that's why he didn't stop that person.

"Ahh~ So-tan I miss you so much" Serafall said as she hugged Sona tightly.

"Onee-sama your embarrassing me!! Stop this at once!!" Sona blushed as she struggled to escaped from her sister's clutches.

"Mou~ there's only three of us here, there's no need to be embarrass in front of Ulqi-tan" Serafall pouted.

Something flash in her mind and she exclaimed, "Ahh!! Speaking of Ulqi-tan, I already prepare our new speech"

Ulquiorra looked at her and nodded.

"Ahhh! That's what I like about you, Ulqi-taaaaaaan!!" Serafall jumped at Ulquiorra.

Sona escaped immediately after she saw her sister was busy talking to Ulquiorra.

"Thankfully, Ulquiorra was there with me or else, I'll never be able to escape." Sona muttered while tidying up her clothes. She really couldn't handle her sister by herself.

She turned her head once more and looked at her sister who was talking to Ulquiorra excitedly. She sighed before she left.
