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

"I believe you."

At that moment, Rio Futaba gazed at the sky filled with torrential rain, her eyes, hidden beneath her bone-white mask, revealing a thoughtful expression.

"However, judging from the intensity of the rain, traffic conditions will definitely be greatly affected, and many sections of the road may be blocked."

"Even if the alarm inside the National Museum is triggered and the Metropolitan Police Department sends reinforcements, it will take a lot of time for them to get here."

"In other words, the only people we need to consider are the Metropolitan Police Department members located in this area."

"The next thing to consider is how to break through the Metropolitan Police Department's defenses and enter the National Museum..."

Just as Rio Futaba was speaking, Yohoshi slowly stood up from her original position sitting on the edge of the Pale Demon Hand, stretched, and laughed.

"Where should we enter? Naturally, we should enter from an undefended area; that would be the most logical approach."

"No defense?"

Rio Futaba frowned slightly.

"How could that be? Yagami just checked, there are Metropolitan Police Department members patrolling all around..."

Rio Futaba froze halfway through her sentence.

She thought of a location: the Tokyo Metropolitan Police Department, which hadn't been fortified at all...

That is...

"Hero, step into the arena!"

Amidst the shocked gazes of Mai Sakurajima, Miko Yotsuya, and Rio Futaba, Yohoshi, dressed in a black coat and wearing a pure black mask, chuckled and said something.

The next second, he leaped straight off the edge of the pale ghost hand, leaving only a trail of black flame.

This is tens of meters in the air!

Upon seeing this, Light Yagami was momentarily stunned, and then a strange fervor and excitement appeared in his scarlet pupils.

"As expected, it's still when I'm with Lord Ye Xing..."

At this point, he actually leaped down from the floating pale ghost's hand.

"That's the most interesting!"

Rio Futaba, Miko Yotsuya, and Mai Sakurajima exchanged glances, each with only one thought in their minds.

These two...

Are they all crazy?

Mai Sakurajima shook her head helplessly, squatted down, patted the palm of the pale demon hand, and said softly.

"Let's descend slowly, following the path they took down."

The pale ghost hand pointed its middle finger, which was the same as a human nodding, and then slowly descended towards the ground.

Meanwhile, underground.

"boom!!!"

Feeling the ground tremble and hearing the sudden, loud noise, the members of the Metropolitan Police Department all changed their expressions.

"what happened?"

"Alert, alert!"

"An intruder?"

.......

The members of the Tokyo Metropolitan Police Department immediately drew their pistols from their waists, turned around, and looked in the direction from which the sound came.

When they saw what was happening in front of them, they were all dumbfounded.

A cloud of dust had been kicked up above the Tokyo National Museum.

On the once solemn and majestic rooftop, there were even remnants of flying pebbles.

"This is..."

The Metropolitan Police Department's on-site commander was stunned and muttered to himself.

"Air...air raid?"

On the other side, beneath the large hole in the very center of the museum, fine cracks have appeared on the marble floor.

Wearing a black coat, Ye Xing knelt on one knee on the ground and slowly raised her head. A white smiley face appeared on her black mask.

"Perfect landing."

Is it really perfect?

Wearing a Ōtengu mask on her face and with bird-like wings growing from her back, Yagami Light slowly landed beside him.

Hearing the piercing alarm in his ears and seeing the mess around him, Light Yagami couldn't help but sigh helplessly.

"You're making too much noise. We're not here to steal anything."

"What do you mean by stealing? What do you mean by stealing? Mikazuki Munechika was originally ours."

"Hesitate, let me put it another way: aren't we here to return the item to its rightful owner?"

"of course."

Ye Xing straightened up, patted the white dust off his coat, and pointed forward.

"So, we have found our target."

Light Yagami looked in the direction he was pointing and saw a beautifully crafted katana lying silently in a glass display case.

"That's the famous sword... Mikazuki Munechika...?"

Light Yagami stared at the katana lying in the display case and murmured his admiration.

"Sure enough, I can feel the powerful spiritual energy emanating from above."

Yoru glanced at the wings on Light Yagami's back.

"You've already mastered the ability to materialize and fuse souls; you have a very high talent."

Light Yagami replied with a smile.

"I'm still a long way from you."

Light Yagami has exceptional observational skills. He gleaned an important piece of information from Yoshinori's seemingly abstract and melodramatic hero entrance.

The distance between the people who were standing and the Tokyo National Museum was approximately fifty meters in a straight line.

At such a great distance, Light Yagami could not sense any fluctuations in spiritual energy.

However, Ye Xing was able to accurately identify which of the many spiritual objects displayed in the National Museum was the famous sword Mikazuki Munechika, and land directly in front of that sword.

To prove that the other party is more than just strength.

Their ability to perceive spiritual energy is also superior to mine.

"Sigh...really, do they always have to make it this elaborate..."

Rio Futaba jumped off the floating pale demon's hand, made a habitual gesture of pushing up her glasses, and looked at Yoruichi.

"You should understand that if things escalate too much and cause public fear, it could lead to unpredictable changes in the underworld, right?"

"Of course I understand that."

Ye Xing nodded, then said meaningfully.

"But it's unpredictable, that's not necessarily true."

"This is... Mikazuki Munechika..."

Yotsuya Miko slowly walked to the display case, looking at the Mikazuki Munechika lying quietly in the transparent glass, her golden eyes revealing an unprecedented look of anticipation and joy.

Both are professional exorcists who fight with swords.

To be honest, after seeing Yoshihoshi's Onimaru Kunitsuna, Yotsuya Miko had long wanted to get her own famous sword that could match her current strength.

On one hand, she didn't want to trouble everyone.

On the other hand, a famous sword isn't something you can just have whenever you want.

And now...

Mikazuki Munechika, one of the Five Great Swords of the World... was right in front of him.

"The glass is bulletproof..."

Rio Futaba walked closer, glanced at the transparent display case, and said softly.

"Bone Woman, make your move."

"it is good."

As Rio Futaba finished speaking, the Bone Woman, dressed in a kimono, appeared behind her. Several white bone spikes extended from her wide robe and pierced the same spot on the glass of the display case one after another.

In just two seconds, the bulletproof glass display case was hit dozens of times at the same spot by bone spikes.

"Click."

With a crisp sound, cracks first appeared on the glass display case.

Then, with a bang, it turned into fragments scattered all over the ground.

Rio Futaba didn't show any joy; she just sighed and muttered to herself.

"Should we find a book about the structure of an electric drill and study it in detail...?"

Rio Futaba had a premonition, even though this was only the second time she had returned something to its rightful owner.

But this will definitely not be the last time.

"Mikazuki Munechika..."

Looking at the famous sword so close at hand, within reach, Yotsuya Miko's eyes showed a hint of nervousness. She took a deep breath to calm her excited heart, and slowly extended her right hand to grasp the hilt of Mikazuki Munechika's sword.

In that instant, Yotsuya Miko saw the pale golden spiritual energy particles in the air freeze instantly.

next second.

"boom!"
