In this crossover anime, I fight against the supernatural in my everyday world.

She rested her chin on her hand, seemingly unconcerned, and asked out of curiosity.

"Ye Xing, I have a question for you."

"explain."

"Is your ability to create things out of thin air?"

Ye Xing shook his head and chuckled softly.

"No, that was just something I showed you casually."

"That's it..."

Amano Hina gave a noncommittal reply, then suddenly spoke up as if she had just remembered something.

"By the way, have you heard of that story that's been going viral online lately, what...yes, 'Mask'?"

"Cough cough."

Upon hearing the word "mask" from Hina Amano's mouth, Yui Yuigahama, who was eating noodles, choked.

Seeing that she was having trouble breathing, Amano Hina immediately stepped forward and patted her back. Then she poured a glass of warm water and handed it to Yuigahama Yui, looking both amused and exasperated.

"Yui, eat slower, why are you eating so fast?"

Yui Yuigahama took the water glass, took a sip, and said with a complicated expression.

"Yeah...I know."

Ye Xing's expression remained calm; he merely nodded slightly.

"Hmm, I've heard that name before, but it's probably just a legend, right?"

"Hey, this isn't just a legend."

Amano Hina paused for a moment, looking mysterious, covered her mouth with her hand, and whispered.

“My younger brother has a playmate who is a student at Kyoto Municipal Kindergarten. That child said that during that incident, he really saw a tall, mysterious person wearing a black mask and dressed strangely.”

"Um..."

At this point, Hina Amano looked at Yohoshi and smiled.

"That mysterious person's height seems to be about the same as yours."

"That's it."

Seeing that Yohoshi didn't seem interested, Amano Hina didn't stop there, but muttered to herself.

"Since... there are special people like you and me in Kyoto, do you think that 'mask' might also be one of us?"

"maybe."

Yohoshi gave a noncommittal reply, looking at Amano Hina with a half-smile.

"So what's your opinion on this 'masked' character?"

"Um...."

Amano Hina frowned slightly, rested her chin on her hand, and thought for a moment before replying.

"If, as rumored, the intrusion into the Kyoto City Museum was also carried out by 'Masked'..."

"Um...but it's a fact that he saved the teachers and students of Kyoto Municipal Kindergarten."

"Is he... a morally ambiguous anti-hero? In any case, he's definitely a hero."

"As for his invasion of the Kyoto City Museum, he must have had his own considerations."

Hearing Amano Hina's words, Yohoshi's expression didn't change much, but Yuigahama Yui breathed a sigh of relief.

She thought to herself that the other person didn't know.

The protagonist of the so-called urban legend was sitting right across from her.

"Mask"?

Yui Yuigahama recalled a sentence that Yohoshi had said before.

"The Metropolitan Police Department will give me a code name."

So this is how you assign codes?

Just then, the lights in the room suddenly started flickering.

"what!"

Upon hearing Yui Yuigahama's exclamation, Hina Amano, while marveling at how timid she was, also offered words of comfort.

"It's nothing serious. It's probably just electrical wiring being renovated somewhere. This kind of thing happens frequently lately. It'll be fine in about half an hour."

Seeing Amano Hina's smiling face, Yui Yuigahama's face turned pale.

The other party was unaware of it.

But she knew it perfectly well.

Since Yohoshi said that an evil spirit has its eye on Amano Hina, then it must exist.

Originally, Yui Yuigahama wasn't afraid.

But then, the lights in the room started flickering!?

what does this mean?

This means that the evil spirit is approaching, and like Hachisaku, this evil spirit has a "gate" fused within its body, making it capable of influencing things in the real world!

Don't let Yui Yuigahama's usually carefree demeanor fool you.

In fact, the psychological trauma she suffered from that incident has not yet healed.

Not every girl possesses the extraordinary mental fortitude of Yotsuya Miko.

"call..."

A sound like a gentle breeze, yet also like breathing, came from outside the window.

"Hiss...why do I suddenly feel a bit cold?"

Hina Amano rubbed her shoulders, shivered, stood up, and walked to the window to close it.

But when she pulled back the opaque curtains, she was stunned by what she saw.

Hanging in the sky was a scarlet moon.

Outside, the train tracks were still there, but further away, there were billowing clumps of thick, black fog.

“What…what’s going on?”

Before Amano Hina could even get a good look, a huge, bloodshot pupil suddenly appeared in front of her.

The sudden, overwhelming terror completely froze Amano Hina's body.

She couldn't even utter a cry of surprise.

Those enormous pupils, like those of a demon from hell, were only a window's distance away from her.

Immediately afterwards, the huge, bloodshot pupils retreated a short distance.

Before Amano Hina could even breathe a sigh of relief, an object that looked like a sharp fingernail, but much larger than a normal person's, stabbed straight at her as she stood by the window.

"Yangcai!"

Yui Yuigahama gasped in surprise, trying to stand up to pull Hina up, but her legs went weak and she couldn't stand up.

At this critical moment.

"Shield."

As soon as the words "Night Star" were uttered, a thick, black shield that almost reached the ceiling of the room appeared in front of Hina.

"boom!"

The tip of the fingernail pierced through the wall and collided with the thick black shield, causing the entire room to tremble.

Amano Hina took a few steps back and collapsed to the ground, almost losing her senses in shock.

"What...what exactly is that..."

"Yin Cai-kun."

Upon hearing Yoshihoshi's voice, Amano Hina turned her head with difficulty.

She saw the other person stand up from the table and stretch lazily.

I don’t know if it’s an illusion or what.

Looking at Yohoshi's expression, Amano Hina sensed that he was a little...

Unexplained excitement?

Is there a sense of joy in the harvest?

"What you see is what our organization is fighting against."

Night Star walked forward step by step, stood directly behind the black shield, and waved his hand, causing it to dissipate.

He stood there by the window, staring into the huge, bloodshot pupil outside, his voice even carrying a hint of laughter.

"We call it, evil spirit."

"Evil spirits are monsters that harbor a twisted hostility toward humanity and are driven by killing and madness."

"but me..."

At this point, a layer of black flames covered Ye Xing's body.

Under Hina Amano's incredulous gaze, his casual clothes gradually transformed into a strange black outfit.

Furthermore, his face was covered with a pure black mask that only revealed his eyes.

It's just like...

The protagonist in the urban legend, "Mask".

Night Star extended his right hand and took Onimaru Kunitsuna from the pale demon hand. Gazing at the huge, bloodshot pupil outside the window, he spoke softly.

"I am their natural enemy."
