I want to be noblesse in dxd

After disappearance of his master, he left left Lukedonia.

And started living a normal life in human society. As the previous lord with other head of the families, decided to go into eternal sleep and pass their position to the younger generation.

And as the new generation took over, they stop interfering in the human society. but just as they cease interacting with human, stray devils and devils started to appear, so are the fallen angels and angels.

After some confrontation, the situation came into control, but there still are one or two cases in a while.

Frankenstein decided to open a school and become the director. So he came to kuoh and started the academy, but 3 years ago when he was sitting in his office, he felt three powerful beings heading towards him.

He quickly prepared himself for any fight, but then he heard them knock on the door.

Knock knock~

"Come in."as Frankenstein gave them permission to enter, three people came in. One male who was in lead, and two female.

The man has long red hair, and green eyes, he was tall imposing with the strength of Satan-class. If we are measuring according to devils society.

Beside him were the two woman's. one was wearing a maid outfit, and has silver hair and silver eyes. And the other girl, height slightly shorter than the both, with raven hair which was styled in a pigtail, and purple eyes.

As frankenstein was watching them the man in lead said." Hello, it's nice to meet you, i am sirzech lucifer one of the maou. On my left side is my wife and queen of my peerage, grayfia lucifuge, and she is serafall leviathan also a satan."

Just st they finished introducing themselves, Frankenstein asked."so what are devil's and Satan at that doing in the human world, and more specifically what business do you have with me."

"We are not here with bad intentions, we came here to make a deal." Grayfia said.

"Deal? Huh.. you can take a seat, my name is frankenstein. By the way, what kind of deal are you going to make, with a normal director of a human school."

As they sit down they started to explain the details.

.....

"Yes, it's not that's complicated frank-chan~ it's quite simple. We just want you to allow our rias-chan and sona-tan to attend your academy."

"Wait, what?! First of all let me sum it up. You have made a deal, with gods of the shinto faction. so that you can send the younger generation of your family in the human world." After a pause he continued." So, they can get experience, on how to govern their estate in the future,"

"and they gave you permission, on the condition that they have to take care, of any supernatural beings or actions in their territory."

"And you want to send them to my school and you are here negotiate with me."

After he finished speaking, grayfia said."it's just as you said."

"First of all, i have stopped paying attention to the supernatural world, and i just want to live a peaceful life, and wait for any news about my master or his return."

"What? You have a master frank-chan~ you look quite strong for a subordinate.'' Serafall asked.

"Yes, now they have stopped interfering in the human society, but when the beings called Noble were active, i used to serve my master 820 years ago."

As he talked about his master nostalgic memories filled his mind.

"So you used to serve an ancient vampire.''grayfia asked.

"Please don't compare these bloodsucker to the nobles, they don't need blood to live. Many don't know but the vampire you see were named on the basis of nobles, because they can use blood related ability."

"And because they stopped appearing. Less people know about them."

''You use to serve one of them?" Sirzech questioned.

''Yes, its been centuries since he got into sleep. I am just waiting for any news about him." Frankenstein said with a hint of pride.

"Enough about my history, let's talk about the matter in hand. You want to send your sisters here in the human world for experience. I can allow them to study here, but please inform them about me. I don't want then to to disturb my life."

"And i won't question them, but if there's something major please tell them to inform me."

"Good hahaha...."sirzech smiled and said.

"I will inform you when the time comes."

"See you again frank-chan." Said serafall.

After some words they teleported away.

....

As he stared at the spot where they had stood, frankenstein sighed.'how have you been master.'

'It seems the world is changing faster than you have expected.'

As he saw pile of documents on the desk, he sighed again."Urhg... more work." He said.

...

The sun hung high in the morning sky, casting a warm glow over the town, filled with people walikng on the road.

It was a time for pepople to go to their respective jobs, It was here, in one of the houses, a man was eating breakfast.

Just as any other day, he got early and after finishing chores and breakfast he got ready to go to work. Three years have passed since the talk with the satans. There weren't any problems happening.

The sister's of maou, with their respective peerage member started attending the academy, like any normal student.

As always he got to school early, and first started checking mails on the computer. After checking them up, he started reading documents placed on the table.

After signing some of the the documents, he placed them at side, and stared straight. As he tried to sense, he felt a familiar presence approaching, which he haven't felt in centuries.

After some time of waiting, the presence stopped in front of the door.

And he heard a knock.
