And the owner is moonbathing on the deck of the roof of the ship, lying in a luxurious summer bed and sipping blackcurrants from the glass.

He was a beautiful man with blond hair and blue eyes, and his appearance was about in his late twenties.

However, his title was, noble. This means that he is a vampire known as the "Old Generation" and possesses superpowers. In his vast territory in the "Realm of the War King", there is always a powerful combat force that rivals the armies of Western Europe. And he himself is a monster with great power to destroy a metropolis in an instant.

A slender figure approached the young nobleman's side.

Standing there was a young girl who looked like a Japanese, slender and slender, with a gorgeous and graceful appearance. She has fair skin and a light hair color. She is a beautiful girl reminiscent of cherry blossoms in full bloom.

The long ponytail fluttered silently with the blowing of the sea breeze.

She was wearing the uniform of a prestigious girls' school in the Kansai region.

In her right hand she was holding a container for a black instrument for the keyboard.

"So it's here, Your Excellency."

The long-haired girl stood there and saluted respectfully.

It was time to see their destination in front of the boat they were on. It was a lonely island floating on the ocean. An artificial island made of a super-large floating structure

An academic research city built for the purpose of controlling the dragon veins.,It's currently conducting research on the ecology and abilities of demons.。 That is, the "Demon Special Zone" Kashin Island.

"Is it a forged earth born of scrap metal and magic, it's really a huge waste. That's what makes humans interesting. ”

The young man muttered to himself in a manner that was both demeaning and praised.

Holding his words to a cold smile, the girl handed out a letter.

"I brought you a letter of greeting from the Japanese government."

“…… Not? ”

As if he had just noticed the girl's presence, the aristocratic young man slowly turned his head. His friendly smile did not carry the sense of coercion that of a vampire with great hidden strength.

Taking his mocking gaze from the front, the girl continued faintly.

"Starting from 0:00 this morning, I admit that Your Excellency has come to visit the "Demon Special Zone" Kashin Island. In the future, according to the provisions of the Sanctuary Treaty, Your Excellency will be received as a diplomatic ambassador to the "War King Domain" - that's it. ”

"Very good, very good conclusion. Even if I was told not to come, I would have landed on my own, but that would have saved me a lot of work. ”

Staying in bed in the summer, Dimitoriye Vatora smiled innocently.

But the girl's expression stiffened as if she was wary of him.

"However, there is one condition."

"Huh. What is it? ”

"I promise to act with the monitors sent by the Japanese government, and I hope you will heed this advice."

"Comes with eyeliner, huh?"

I see, Vatora nodded as if amused.

"So, who is that watcher?"

"I take the liberty of taking this position."

The girl answered the question in a calm tone and with a provocative expression contrary to her tone.

Since she is a self-proclaimed watcher, her mission is certainly not just a tour guide.

At the time when it was discovered that the existence of Wattola would threaten the Japanese government. In the worst-case scenario, she would wipe him out, and that's what she declared. At the same time, it also means that the girl has the power to destroy the vampires of the "ancient generation".

Hearing this, Vatora turned her head and looked at the girl incredulously.

"Ah, by the way, who are you?"

Faced with the words of the aristocratic young man who beautifully revealed indifference, the girl sighed slightly.

"My name is Sayaka Kasaka. The Lion King organ is allowed to press the person with the title of Mai Wei Yuan. ”

"The Lion King Mechanism? I don't think I've heard this name before. ”

Vatora muttered in a voice devoid of tension. The girl shook her head impatiently and helplessly.

"It is a secret service of the Japanese government that is responsible for dealing with the terrorist activities of the magicians."

“…… Magical terror? ”

"Your visit to the city will be the subject of surveillance by the authorities, so we will walk with you, please agree to this."

"Yes. Well, it's okay anyway. ”

The young aristocracy easily accepted this. Then he narrowed his eyes and smiled.

"Having said that, the inspector sent by you turned out to be a lovely woman like you, and the Japanese government really doesn't care about the atmosphere."

It's even better if it's a cute boy. Saya Hua looked at Vatora with a rather unpleasant gaze, who was talking to herself.

"Nevertheless, Your Excellency. Don't look at me like this, I'm also a demon attacker who is licensed to hold a six-style heavy demon slaying bow. Please don't forget that I have been granted the right to kill you at my own discretion. ”

He thought that Sayaka's threatening words out of displeasure would make him emotionally fall, but to his surprise, Wattola laughed in a pleasant voice.

"Hahaha, that's good. You're quite interesting, I like it. That's right, that's right, my words, whether it's Dima or Wattola, you can call it whatever you like. Solemn titles like Your Excellency should be excused. ”

“…… I see, Arudiya Rugong. ”

Sayaka's attitude towards his demeanor has not changed. Vatora's demeanor became obscene, and then he sat up and looked at Sayaka, his eyes shaking like two waves of red heat.

"So, what about my other request?"

"Wish...... Is it? ”

Sayaka's expression stiffened at the cold atmosphere that emanated from Vatora's body.

"Don't pretend to be stupid until now, okay. You've already found him, and he's under surveillance, right? It's the strongest vampire thing in the world. ”

"If it refers to the Fourth True Ancestor, I don't deny it, so I'll tell you."

Facing Sayaka, who reported with a calm attitude, Vatora smiled slightly.

"Be sure to introduce him to me, though I don't understand how you feel about trying to hide him."

Although the aristocratic young man's face still had an amiable smile, his whole body was now emitting a terrifying spell that seemed to be under physical pressure. It was a state of crazy emotion as if it had materialized. If it weren't for a demon attacker, but an ordinary human, it would not be surprising that losing consciousness was such a strong evil aura.

But Saya Hua shook her head quietly with an expressionless face.

"No, there's no reason to hide him for shelter."

As she said this, she took out a photo. It was a photo of a male high school student in uniform. An ordinary boy who seems to be seen anywhere.

Xiao Gucheng, that's his name.

The horizon began to glow white, and soon the night was coming to an end.

"Because the Fourth True Ancestor Xiao Ancient City is our enemy—"

In the hands of Saya Hana, who was whispering like this, the photo of the teenager was crumpled into a ball.

The ship carrying the young nobleman and the girl is slowly approaching the island of the string god.

……

One Wednesday in mid-September, at 6.25 a.m. -

That morning, Xiao Gucheng woke up on his own.

It can be said that it was an unprecedented accident at all. Although it is not a fact worth disclosing to the public, Xiao Gucheng is actually a vampire, and vampires have been a race that has been very afraid of sunlight since ancient times. Even with a title as "Fourth True Ancestor", which seems to be remarkable, this is the same in this regard. Especially in the morning, the sun is even worse. Although it is not as severe as being burned to ashes when exposed to the morning sun, there are various distressing symptoms such as a strong feeling of fatigue, detachment, drowsiness, fatigue, and loss of appetite. The trouble is that this symptom seems to outsiders to be no different from ordinary people who don't get enough sleep after staying up late, and that's it. So in the eyes of ordinary people, this kind of person is a bad department.

But in fact, the ancient city also stayed up late, because of the vampire system, which made him more energetic at night, he couldn't sleep at all, and he didn't have the heart to study in the morning.

If he wanted to keep his grades at the top of the school, he could only study at night and stay up until two or three o'clock before going to sleep, which caused him to be so tired in the morning.

Although in the eyes of outsiders, the ancient city has excellent grades and outstanding motor nerves. There's a charming appearance and strong ability.,Faced with the cold arrogance of girls other than Nagisa、Light onions、Yukina.。 With impeccable ability, unpredictable and fluctuating language behavior, he has become a "celebrity" that everyone knows in Caihai School.

He is the most popular boy in the school, not only is he often confessed by girls, although he also ignores girls, but he is also very prestigious among boys, and they all use honorifics against him. But who knows what kind of hardships the ancient city has under this dazzling aura.

Although the learning ability of the ancient city is indeed amazing, as long as you know some basic information, you can understand it all.

But everything he has now is made by his own efforts.

……

"Huh!" Thinking of these things, Gu Gu couldn't help but sigh on his face.

"That...... Senior, what's wrong? …… Are there any worries? ”

In the train car on the way to school, Yukina, who was wearing a school uniform, asked the old city.

She carries a black guitar case for bass on her shoulder.

The contents of the box weren't actually real musical instruments, but the Lion King's secret weapon, a powerful spirit spear supposedly designed to erase the vampire's true ancestors.

As the watchdog of the "Fourth True Ancestor" Xiao Ancient City, Xue Na usually usually would not leave such a dangerous prop. However, whenever Gucheng saw her figure, he couldn't help but feel very melancholy.

"Nothing?"

There was only one thing on his mind, why did he come back into this world? Become the Fourth True Ancestor. What is the crisis of the imminent destruction of the two-dimensional world that Cone Shengling said? These ancient cities had never thought of before, but after listening to what Cone Sheng Ling said, he had to think about it, because Cone Sheng Ling had said that he was the only one who could save the two-dimensional world. No matter what, it means that the road in the future of the ancient city will be extremely bumpy, and his life is destined to be extraordinary.

"Hey, Ancient City King......"

"Hey, Gucheng-kun, you have something to say!"

"Huh?" Interrupted by his train of thought, the ancient city finally realizes that Nagisa is calling himself. "Apologize, I was thinking about things just now, I didn't hear it clearly, can you say it again?" (Markne)
