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

As Rio Futaba and Hone-onna finished speaking, the train suddenly began to shake violently.

"What...what happened!?"

Before Yagami Soichiro could even prepare, he witnessed an astonishing sight that he and Kitagawa Kaimu would never forget for the rest of their lives.

Before Rio Futaba, at the junction of the two carriages, a huge white wall suddenly rose up, resembling a pile of bones, with patterns of crying and roaring carved on it.

The wall was so massive that it completely blocked everyone's view until it filled all the gaps in the underground passage before slowly coming to a stop.

"What...what...what is this?"

Soichiro Yagami and Saki Kawasaki stared in disbelief, unable to believe their eyes.

In comparison, Kitagawa Kaimu, having been exposed to otaku culture more and possessing a richer imagination, is slightly better than the other two.

But it's just a little bit.

Seeing a scene that only appears in anime actually happening right in front of him, Kitagawa Kaimu was filled with disbelief.

Only Kawasaki Kyoka rested her chin on one hand, swinging her two little legs.

Let alone being shocked.

Judging from her expression, she seemed a little bored.

What a Wailing Wall!

It's meaningless at all.

Kawasaki Kyoka just wanted to see her older brother take action and eliminate those monsters.

She had absolutely no interest in the petite woman dressed in a stark white, bone-like outfit.

Perhaps this is what is meant by "Night Star's one-sided support".

Looking at the massive, thick wall of white bones that had risen before her, a wall that occupied the entire underground passage, Tamamo-no-Mae glanced at Rio Futaba with interest.

She noticed that after unleashing such an ability, the other party only took a slight breath and looked somewhat tired, but clearly, they had not yet reached their limit.

Tamamo-no-Mae was very curious.

When they first met not long ago, this petite girl with large breasts in certain areas was just an ordinary human being who trembled in fear in front of him.

But now, he actually possesses a power at this level that makes him feel dangerous.

Such a rate of growth is simply too fast.

Thinking of this, Tamamo-no-Mae felt even more fortunate for her decision to come here today.

She looked at Ye Xing, who was sitting there with an unwavering expression, and thought to herself.

Can someone not only be powerful themselves, but also guide those around them to become stronger?

I just don't know...

Could such methods be effective against someone like me who is not human?

Tamamo-no-Mae also wants to become stronger.

at this time.

"boom!!!"

The Wall of Sighs suddenly trembled violently.

The entire underground passage was shaken down by the sudden impact, sending up a cloud of dust.

Not only Kitagawa Kaimu and the others, but even Futaba Rio herself was startled by the sudden tremor and shrank back.

However, she then began to observe the Wailing Wall she had created, noticing the cracks appearing on it, and muttered to herself.

"Hmm... If there's another impact, I won't be able to withstand it. That guy's strength is very strong."

"You've done a good job."

Yohoshi patted Rio Futaba's head and chuckled as she praised her.

A demon capable of creating such bizarre events and merging such a large area of ​​the real world with the underworld must possess extraordinary power.

It's probably not much different from that giant evil spirit.

With Rio Futaba's current power, it's already quite impressive that she can withstand a full-force attack from an evil spirit of this level.

Each person's ability to materialize their soul has a basic type.

For example, Emperor Sutoku of Yagami Light.

Emperor Sutoku, with his incredible speed, preferred killing rather than fighting evil spirits.

This is also the effect brought about by Light Yagami's true inner feelings.

The same principle applies to Yotsuya Miko's hundred eyes.

She herself is not afraid to fight against evil spirits at all. And because of her experience of having to pretend not to see them every day before meeting Ye Xing after awakening her Yin-Yang Eyes, she deeply hates the existence of evil spirits and wishes she could wipe them out of the world completely.

Therefore, her true soul form, Hundred Eyes, is more of a support type, specializing in finding traces left by evil spirits.

Rio Futaba's Hone Woman form's most proficient ability type is also related to her inner state when she awakened.

defense.

Or rather, it is the power to protect others.

Rio Futaba has always wanted to be someone who is needed by others.

This power is the ability she awakened to protect Xyz Society and those who need her, and whom she needs.

"It is indeed a very powerful monster..."

Even with the wall of sighs formed by white bones blocking her way, Tamamo-no-Mae could vaguely sense that the being on the other side of the wall was radiating a sense of danger that even made her heart tremble.

After saying that, she glanced at Ye Xing sitting there and quickly began to explain.

"I had no idea that such a monster existed underground in Kyoto City. I'm not deliberately hiding it from you..."

"Alright, no need to explain."

Ye Xing waved his hand, interrupting Tamamo-no-Mae.

The other party truly had no reason to deceive me.

Moreover, contracts cannot be broken.

Even at this moment, Soichiro Yagami had not forgotten his duties as the head of the Criminal Investigation Bureau.

Through the conversation between the two people and the spirit, he confirmed one thing once again.

Whether it was the mysterious person with golden pupils from last time, or the unidentified person who, according to passersby, wore pure white clothes and had medium-length brown hair and helped wipe out that violent gang, or the person in front of me who could create a huge white wall with a wave of his hand.

When working with "Masked," these people obey his orders.

Only "Masked" participated in all of these events.

By this point, Soichiro Yagami was no longer pursuing the other party's true identity out of a sense of duty as the head of the criminal investigation department.

After all, high-ranking officials in the Metropolitan Police Department had already given him hints.

If information about beings like "Masked"—whose very existence is uncertain—were made public, it would only cause panic among the public, further eroding the already precarious level of public trust in the Kyoto Metropolitan Police Department.

not to mention...

In the incident of the invasion of the Kyoto City Museum, regardless of whether Soichiro Yagami was willing to accept it or for what reason, he had to protect the cultural relics, protect the lives of his subordinates, and prevent them from sacrificing themselves in vain.

In a practical sense, he has become an accomplice of "Mask".

There's a word that describes Soichiro Yagami right now, and it might sound a bit odd.

But there really weren't any more suitable words.

Evil depravity.

The brief moment of calm following the initial impact did not lower everyone's guard.

On the contrary.

An extremely dangerous premonition lingered in everyone's mind.

The underground passage trembled once again.

"coming."

Even without Tamamo-no-Mae's special reminder, Yoru-no-Shiki knew that the evil spirit opposite them, whose true form they had yet to see clearly, had launched another attack.

The Wailing Wall could not withstand a second impact.

"Chief Yagami."

Upon hearing Ye Xing's voice, Yagami Souichirou couldn't help but raise his head, watching as the other person walked step by step towards the white wall.

"I once told you that the world is not what you imagine it to be."

"Kyoto City is in an unprecedented crisis that is completely unimaginable to ordinary people."

Souichirou Yagami frowned and spoke in a deep voice.

"Are you trying to say that you are the one protecting justice in Kyoto City, and that the Metropolitan Police Department is just an obstacle in our way?"

"An obstacle... You do have a very clear self-perception."

Ye Xing shook his head, then said softly.

"But justice... I don't care about that. I'm not someone who pursues justice; it's just that what I want to do happens to be just."

At this point, Yosei turned around and looked directly into Soichiro Yagami's eyes.

"That's why I have no constraints on my body and no restrictions on my movements."

"I don't care at all about what other people think, what the Metropolitan Police Department thinks, or even what the world thinks."

There is only one thing I care about.

Ye Xing stretched out his right hand to his side, and a huge pale demon hand appeared in mid-air. Excitedly emitting a metallic clang, Onimaru Kunitsuna automatically unsheathed himself and handed himself to Ye Xing's hand.

"That is..."

Watching the jet-black blade leap and chirp excitedly in Yoru's hand, Onimaru Kunitsuna's expression became extremely complicated.

This famous sword...
