I'm surrounded by devil sisters!

"Hey~ Good evening! It's so hard for Genshin Island to host its annual fireworks display. Why are you so high up here if you can't enjoy the fireworks from down below? Are you looking for the VIP seats?"

The sudden gust of wind carried the boy's half-joking voice, causing the silver-haired angel girl, who was flying at high speed just a second ago, to come to a sudden stop.

She suddenly retracted her forward momentum and braked slammingly at a height of hundreds of meters above the ground. With her feet dangling in the air, she looked in the direction of the sound. The figure of the young man was reflected in the silver-blue eyes under the mask.

This was definitely an unexpected development, but for some reason the silver-haired girl's eyes did not reveal any surprise.

To be precise, there was no emotional fluctuation at all.

Huakaiyuan Fogui smiled and spread his hands.

"Just a reminder, this isn't Fuyuki City. We can't keep fighting the Holy Grail War every day. How about we call it a day?"

“Gah!!!!”

However, the only response he got was a shrill scream from the silver-haired girl beneath her mask, which was completely unhuman.

Oh my, why does it seem like we can’t communicate at all? Let me ask you... huh?

Hearing the whistling wind behind him, Huakaiyuan Fogui paused slightly, then turned his head to look behind him.

I saw that the other black-haired angel girl who had been constantly distanced from each other was now swooping towards this side at an extremely fast speed while the two were chatting. The distance between the two sides had been shortened by half in less than two seconds. The silver-haired angel girl suddenly screamed because she noticed the attack from the other party.

It only took less than two seconds to cover a distance of hundreds of meters, and in the time it took Huakaiyuan Fogui to turn his head, the opponent had already reached him.

She put the five fingers of her right hand together, and a mysterious power immediately attached to them. She raised it high and was about to stab the silver-haired angel girl opposite her, passing over Huakaiyuan Fogui.

"Hey, that won't do."

At the critical moment, the boy coughed lightly.

Just as the black-haired angel girl was about to stab with her knife, a young man's warm and powerful hand gently grabbed her wrist. The gentle movement made people feel like he was holding a young, disobedient and angry sister.

The seemingly fatal blow was just suppressed.

At the same time, the silver-haired angel girl on the other side also launched a counterattack. A powerful white energy ball gathered in her palm and quickly took shape. When she raised her hand, she had locked onto the black-haired angel girl who was one person away. It was obvious that she intended to take this opportunity to send the other party away directly.

Then the ball of energy in her hand was taken away by Hua Kaiyuan Fogui with ease.

"This one is also good."

Hua Kaiyuan Fogui casually threw the energy ball a thousand meters above, letting it explode and dissipate on its own, and then turned around and chopped the silver-haired angel girl's head with a knife.

The intensity is just right, and it doesn't hurt your brain.

Click.

A shattering sound was heard, and the silver-haired angel girl, who had been screaming and wanting to fight to the death with the black-haired angel girl just a second ago, suddenly became quiet, and at the same time a crack appeared on the mask.

Then it expanded rapidly.

Click, click, click.

There is a saying that a defeat is like a mountain collapsing. The mask with a crack on it seemed to have entered collapse mode on its own. One minute and three minutes, three minutes and nine minutes, and within a few seconds the entire mask was covered with fine cracks.

Oh?

Huakaiyuan Fogui couldn't help but raise his eyebrows when he saw this. While using the power of the magnetic field to control the black-haired angel girl on the other side, he raised his hand and gently flicked the cracked mask on the silver-haired angel girl's eyebrows.

wow-

Like the autumn wind blowing dead leaves off a tree, the mask, which had long been shattered, completely shattered under this slight vibration. It was swept away by the oncoming high-altitude airflow, revealing its true appearance.

Fair skin, delicate features, and those iconic silver-blue eyes, just as they were when we first met.

"really."

A hint of understanding flashed in Huakaiyuan Fogui's eyes.

Although he didn't understand why, he felt that it looked familiar when he saw it from afar before.

After all, there are not many people with silver-white hair in this world, and this is especially so in this small Xianshen Island.

This so-called silver-haired angel girl confirmed that she was the junior high school saint, Natsune Yezane, whom he and Asagi Aoi met this morning in the abandoned church on the back hill of the Saikai Academy High School Department, who was feeding cats with Nagisa Akatsuki and Setsuna Himeragi.

"Big...Brother..."

As the mask shattered, Yeze Natsune's power seemed to dissipate as well.

She used up her last bit of strength to softly call out "Big Brother", then closed her eyes and lost consciousness.

……

The scene changed, and Hanakaiin Fukui had brought the unconscious Yeze Natsune and another black-haired angel girl back to the square on the top floor of the building where Nangong Nayue and the others were before.

When she saw the young man appear, Nangong Nayue walked up to him immediately and carefully observed the two girls he brought back.

"This is... yes, the bodies of the defeated we found at the scene of the battle looked like this before."

"Wait, wait! Teacher Nangong, you mentioned the bodies of the defeated... Could it be the ones that caused damage in the city center a few days ago? But this child isn't..."

Asagi Aoi showed a look of surprise at the sight of the unconscious Natsune Yezawa.

After all, it happened this morning, and she had just met the other person less than ten hours ago.

It’s in the church on the back hill of the high school.

Hanakaiin Fukui, who had known this for a long time, shrugged.

"That's right, so what should we do next?"

"Leave the rest to us. You just stay here with your girlfriend and continue watching the fireworks..."

Nangong Nayue raised her hand and summoned the power of Locking Chain that she possessed as the Gap Witch, firmly controlling both girls.

She turned around and opened the portal to the security building. Before leaving, she looked back and warned.

"Don't follow me."

"……Why?"

Huakaiyuan Fogui was puzzled. After all, it was he who caught the person.

"Because if nothing unexpected happens, I'll have to work overtime again tonight."

Nangong Nayue snorted.

"It would affect me if you were around."

"Is it not possible to not speak?"

Huakaiyuan Fogui raised his eyebrows and asked.

"It doesn't matter if I talk to you or not."

The gothic girl in a kimono shook her head.

"It's true that wherever you are, the air is filled with a scent that can make women pregnant, and I don't want to get pregnant yet."

"Astaruti doesn't mind..."

Astaruti on the side seemed to want to say something, but Nangong Nayue grabbed her hand and dragged her away.

"Let's go, Astaroute."

"Well……"

Chapter 331 Sister, um, where is my sister?

Despite being explicitly rejected by the Gothic girl, Hanakaiin Fugui's ideas have always been simple and crude.

If you tell me not to follow you, I really won’t follow you. Wouldn’t that be very embarrassing for me?

The scene then shifts to the special security team headquarters building on the island.

Pure white corridors, complete ventilation equipment, and operating rooms along the way.

This is a confidential floor located underground in the Special Guard Headquarters building. Normally, only seriously injured Special Guard members and guard officers at the rank of director and above can enter here. If others want to come in, they need to report to the artificial island management commune for approval.

Nangong Nayue just happens to belong to the latter category. She is the demon attack officer of the Special Guard Team of Genshin Island. Her title is director and she has the authority to come here.

And she also brought a special guest today, that is, Yeze Natsune who was pulled down from the fireworks by Hanakaiin Buddha before.

Oh, to be precise, there are actually two people. The other one is the black-haired masked angel who had fought with Natsune Yezane before. He is now undergoing a physical examination by professionals from the medical department of the security team in another operating room next door.

As for Yeze Natsune, Nangong Nayue is personally in charge.

The shadowless light was on, and a flawless, angelic silver-haired girl lay quietly on the operating table in the middle of the room. Her fair body was covered with wires for sensing her physical condition. Only the regular dripping sound representing her heart rate echoed in the quiet air.

"So what's going on now?"

Next to the operating table, Hua Kaiyuan Fogui used matter reorganization to conjure up a chair and sat down. He held his chin and looked at the silver-haired girl who was still in a coma on the operating table curiously.

Anyone would be curious.

After all, it was only half a day. When I saw her at school in the morning, she was still an ordinary human girl, but when we met again in the evening, she had turned into a masked bandage girl with angel wings on her back who could fly, scratch people, and shoot light cannons.

This gap is too big.

"...Didn't I tell you not to follow me?"

Nangong Nayue didn't even bother to turn her head when she heard the voice, and continued to operate various instruments in the operating room.

"That won't work."

Huakaiyuan Fugui yawned with his hand covering his mouth, then turned to look at the blonde girl who was also sitting on the chair next to him and looked a little nervous.

"If she was a stranger, it would be fine, but she's my sister's classmate and good friend, and she and Asagi just met this morning. It would be incredibly irresponsible to just leave her here."

"younger sister?"

Hearing this name, Nangong Nayue, who was still operating the machine a second ago, paused for a moment and looked over with a puzzled look.

"Hakaiin Yuura attends Saikai Academy?"

"Oh, it has nothing to do with Yuura, I was talking about Nagisa."

Huakaiyuan Fogui scratched his head.

"Because she always calls me big brother, so of course she is my sister."

"……Really."

Nangong Nayue thought for a moment and turned her head back.

She had no interest in disclosing other people's privacy, and with this guy's outrageous behavior, who knew whether Asagi Aoi, his real girlfriend, had known about the relationship between her boyfriend and his two "sisters" for a long time.

After all, we have already seen people being hugged on both sides, so it doesn’t seem impossible to have another person sitting in the middle.

But then again, young people nowadays are really into playing around...

The old Gothic witch aunt, whose real age is 26 but still maintains a loli body, couldn't help but think.

"Ok?"

As a new set of data appeared on the screen, the Gothic girl who had been repeatedly clicking the refresh button was suddenly stunned, and then her eyes suddenly became serious.

"Wait, this is..."

"what happened?"

Noticing Nangong Nayue's mood changes, Huakaiyuan Fogui also realized that the other party had obviously captured some key information, so he stood up and quickly walked to the computer controlling the instrument.

But he gave up after just one look.

Because I can't understand those complicated data at all...

Nangong Nayue didn't look at him, but just stared at the screen, shaking her head and muttering, "Although it may be a bit embarrassing to say this, it seems that you really came here for the right reason... I'll just ask directly, did you notice anything unusual when you were in contact with them before?"

"If I had to put it bluntly, it would be that someone seems to be controlling them."

Huakaiyuan Fogui recalled the situation at that time.

"So what happened?"

"I do not know either……"

Nangong Nayue took a deep breath.

"According to the results of the instrument's detection, the number of spiritual centers in this girl's body has exceeded that of a normal human several times. This is absolutely impossible."

"Hmm, I don't understand."

"... Let's put it this way. Normal humans are born with seven spiritual centers. Being able to unleash 30% of their energy is already a first-rate spiritual power user. And if you can fully unleash and perfectly utilize them, you can become an enlightened being, gaining power comparable to that of gods and Buddhas."

The Gothic girl said this and glanced at the data on the computer screen.
