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

As "Mask," he has no inhibitions and can display his power, which is beyond the imagination of ordinary people.

"So..."

Yoru walked to the front of the "door," turned around and looked at Yagami Souichirou. On the pure black mask, a white pattern like a smiley face appeared.

"Until we meet again, Chief Yagami."

As Yoru's figure gradually disappeared, Yagami Souichirou breathed a long sigh of relief.

He leaned against the wall of the alley, disregarding his neat black suit, and slumped down on the dirty, sewage-covered ground. His gaze fell on the unconscious Aguya Kiyoaki, and he muttered to himself.

"What...what have I done...?"

......

Half an hour later.

"came back."

Yotsuya Miko and Yohoshi passed through the "door" and appeared in the living room of Futaba Rio's house.

Rio Futaba and Yui Yuigahama both breathed a sigh of relief upon seeing the two return safely.

Rio Futaba glanced at them and saw that there were no obvious injuries on Miko Yotsuya and Yohoshi. The worry between her brows finally dissipated. She pushed up her glasses and said in a calm tone.

"Did you get the goods?"

"of course."

In the other world, Yotsuya Miko had already changed out of her disguise, in order to avoid leaving any trace for the Metropolitan Police Department to investigate.

She sat down on the soft sofa. After staying up all night and engaging in a tense and exciting invasion, she was already exhausted, both physically and mentally. She yawned, lay down on the sofa, and lazily rubbed her eyes.

"I'm exhausted, I'm going to take a nap."

"Oh, there are guest rooms..."

Before Rio Futaba could finish speaking, Miko Yotsuya fell into a deep, baby-like sleep.

It's clear that she was truly exhausted.

"Oh, it's true."

Rio Futaba shook her head helplessly, poured a steaming cup of coffee, and pushed it in front of Yohoshi.

"Tell me, what happened?"

"walk slowly."

In the next ten minutes, Yoruichiro will invade the exhibition hall, Onimaru Kunitsuna will recognize him as his master, reach an agreement with Yagami Souichirou, defeat Akoya Kiyoaki, and a series of other events will be told to Yuigahama Yui and Futaba Rio.

After listening, the two women both looked somewhat complicated. They exchanged a glance and then complained in unison.

"You call yourself a phantom thief? You're more like a robber!"

"Same here, just get the items."

Rio Futaba sighed softly, a complex expression appearing in her eyes behind her glasses, and murmured.

"The famous sword Onimaru Kunitsuna has been stolen... This will surely become the news that shakes the entire Sakura Province."

"what are you talking about?"

Night Star shrugged and smiled meaningfully.

"Onimaru Kunitsuna, it wasn't lost at all, understand?"

"Ok?"

Yui Yuigahama looked puzzled.

"Wasn't it already stolen by you and Miko... no, wasn't it returned to its rightful owner by you and Miko? How can you say it wasn't lost?"

Rio Futaba understood the meaning behind Yoruhoshi's words, her brows furrowed slightly, and she asked with some doubt.

"You mean, the museum and the Metropolitan Police Department would deliberately conceal the fact that Onimaru Kunitsuna was lost? That's impossible, isn't it?"

Night Star shook his head.

"Futaba, you may be very intelligent, but ultimately, you don't understand the complexities of human nature."

"Yeah..."

Rio Futaba simply muttered something to herself without offering any rebuttal.

She knew that her strength lay in intelligence gathering and analysis.

When it comes to understanding the complexities of human nature, Ye Xing, sitting across from me, is far more adept than I am.

Rio Futaba didn't think there was anything shameful about it.

nobody is perfect.

Wasn't Yosei's initial purpose in establishing the Superpower Society to bring together members with different strengths, so that they could compensate for each other's weaknesses and fight against supernatural events to protect Kyoto City?

As long as you do what you're good at, that's enough.

"correct."

Yui Yuigahama's eyes gleamed with curiosity.

"Onimaru Kunitsuna, could you show it to us?"

Upon hearing this question, Rio Futaba didn't show it so obviously, but a hint of anticipation still shone in her eyes behind her glasses.

"of course."

Ye Xing smiled and responded, then summoned the Pale Demon Hand, took Onimaru Kunitsuna from its sheath from the five fingers of the Demon Hand, and placed it horizontally on the table.

"This is it, watch it for as long as you want, don't be shy with me."

At this moment, Rio Futaba and Yui Yuigahama were no longer concerned about Yohoshi's inappropriate tone.

"This is... Onimaru Kunitsuna..."

The two women's gazes were fixed on the ancient wooden scabbard, their pink lips pursed, and their breathing became heavier.

Hojo Tokimasa, Oda Nobunaga, Toyotomi Hideyoshi...

All the previous holders of Onimaru Kunitsuna were people who played an important role in the history of Sakura Province.

Calling this famous sword a timeless treasure that has witnessed hundreds of years of history in Sakura Province is no exaggeration.

Rio Futaba stretched out her fair right hand, seemingly wanting to touch Kunitsuna Onimaru in front of her, but when her hand was halfway out, she felt that it was somewhat disrespectful and stopped in mid-air.

Night Star saw through her thoughts and chuckled as she spoke.

"Unsheathed."

As soon as those two words were uttered, Onimaru Kunitsuna, who had been hidden in his scabbard, sprang out on his own.

The deep, pure black blade made the light emanating from the chandelier in the living room appear somewhat dim.

Seeing Onimaru Kunitsuna automatically unsheathe his sword, Yui Yuigahama and Rio Futaba were so shocked that their pupils dilated.

"You actually... became the master recognized by Onimaru Kunitsuna?"

This famous sword, once wielded by so many renowned historical figures, actually bowed down before Ye Xing?

It is obvious that Onimaru Kunitsuna, a powerful spirit that has been passed down for hundreds of years, has already developed its own intelligence.

Does this mean...

In Onimaru Kunitsuna's eyes, Yoshinori, like Hojo Tokimasa, Oda Nobunaga, and Toyotomi Hideyoshi, was a figure who would have a significant impact on history and be remembered in history.

So the Supernatural Quantum Mechanics Research Society I belong to is this powerful?

only...

Rio Futaba glanced at the blade of Onimaru Kunitsuna and asked in confusion.

"This knife wasn't originally this color, was it?"

Ye Xing's answer was very brief and bland.

"It is now."

Just then, Ye Xing's phone suddenly rang.

He stood up and smiled at Yui Yuigahama and Rio Futaba.

“I’m going to take a call. You can watch for as long as you want, and you can even touch it. It’s the common property of our Superpower Society.”

Upon hearing this, Yui Yuigahama nodded excitedly, and carefully reached out her fair right hand to touch the blade of Onimaru Kunitsuna's sword.

"Snapped."

Yui Yuigahama winced in pain, pulled her hand back, and looked at Rio Futaba with a pitiful expression.

"Why did you hit me?"

"You really want to touch it?"

Rio Futaba shook her head helplessly and said in a low voice.

"This is a legendary sword, a weapon with sentience. Aren't you afraid of being attacked by it?"

Upon hearing this, Yui Yuigahama gasped, thinking to herself, "That's really true."

Although Onimaru Kunitsuna recognized Yohoshi as his master.

But the one being recognized isn't oneself.

A sword like this, capable of slaying demons, must be quite temperamental, right?

Just as Yui Yuigahama and Rio Futaba were thinking this, they saw Kunitsuna Onimaru float up.

Then, it moved closer to Yui Yuigahama and carefully placed the blade of its knife into her palm.

Yui Yuigahama and Rio Futaba were stunned for a moment, and at the same time, an idea came to them.

Good guy.

Onimaru Kunitsuna, is he actually a sword-licking enthusiast?

Of course, they didn't feel that this famous knife was trying to please them.

This is clearly an attempt to curry favor with Ye Xing.
