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

Yui Yuigahama?

Yuigahama Yui!

"Yui, come here quickly."

Rio Futaba pulled Yui Yuigahama, who was still in a daze, over, adjusted her glasses, and said meaningfully.

"Ye Xing broke the school record, don't you want to say something to him?"

"Eh?"

Looking into Rio Futaba's eyes and hearing her meaningful tone, Yui Yuigahama was slightly taken aback.

Immediately afterwards, she suddenly looked flustered, waved her hands repeatedly, and even took two steps back, deliberately moving away from Ye Xing.

"No...no, I absolutely have nothing to say, Rio, don't overthink it, I don't want to tell him anything!"

This time, Rio Futaba was caught off guard.

She wondered if she had misunderstood something.

Even though it was so late during the last group chat, Tuanzi and Yexing were still together.

There must be something going on here, right?

Why is Yui reacting with such fear when she asks for outside help to fight against Sakurajima Mai?

Shouldn't it?

Seeing this scene, only Ye Xing could understand what had happened.

simply put.

These two have an amazing skill.

Rio Futaba isn't very good at understanding what others are thinking.

The other one, Yui Yuigahama, is overly gentle and timid.

The two versions don't match up now.

Rio Futaba's side is a group that is fighting against the Great Demon King Mai Sakurajima, which is a case of outnumbering the enemy to defeat the boss.

Yui Yuigahama thought that this was a one-on-one PVP battle.

Just then, the eight-foot-tall man suddenly floated behind Ye Xing, lowered his body and whispered.

"Boss, someone... no, a spirit is looking for you."

Ye Xing didn't answer, but just nodded slightly. After all, it would be too strange to talk to thin air in public.

After leaving the playground with the eight-foot-tall man, they arrived at a secluded corner of the campus.

"Lord Night Star, you've finally arrived."

Holding an oil-paper umbrella, Tamamo-no-Mae, dressed in a plain-colored kimono, stood there.

"Oh, it turns out it's you."

When Yohoshi heard Yasakani's announcement, he could roughly guess that it was Tamamo-no-Mae who had come to find him.

After all, the only strange entity that can be considered an ally of the Xyz Society is the other party.

How did you escape from the other world?

Tamamo-no-Mae sighed softly, looking at Yoru with resentful eyes, like a wronged woman who had been abandoned, and complained softly.

"Lord Night Star, it's been a long time since you last came to see me."

Faced with such a stunningly beautiful demoness as Tamamo-no-Mae, speaking in such a resentful and reproachful tone, with such a soft and sweet voice, any normal man would probably melt at the mere thought of her.

Night Star is also a man.

But he's not normal.

"Stop barking."

The three simple words, "Night Star," completely stunned Tamamo-no-Mae.

"When I want to eat you, I'll come looking for you."

Upon hearing this, Tamamo-no-Mae forced a smile, subtly taking two steps back to distance herself from Yoru-hoshi.

Although she hadn't witnessed it firsthand, she had heard about the battle that had taken place in the inner world a couple of days ago from the little demons under her command.

A giant evil spirit, ten meters tall, fused with the power of the "door".

Even without the ability to think rationally, one can become a dominant force in the inner world solely through one's own strength.

Although Tamamo-no-Mae made a contract with Yohoshi, it did not include the clause that she would help him when he was in danger.

As a powerful demon who has lived for hundreds of years, she is clearly not the kind of being who harbors goodwill towards humans and would be willing to sacrifice herself for them, so of course she would not intervene in the battle.

What Tamamo-no-Mae didn't expect was...

Night Star, being human, actually won.

Furthermore, according to reports from the monsters hiding in the shadows at the scene...

They won easily, and the scene was extremely brutal.

That giant evil spirit...

After being torn apart by Ye Xing, he was directly killed by the opponent.

Tamamo-no-Mae knew that Yoru-hoshi was very strong.

But she really didn't expect it to be this strong.

What exactly is the upper limit of the opponent's strength?

After realizing the unfathomable nature of Yoruhoshi, Tamamo-no-Mae's attitude changed.

She initially thought that the two of them had an equal working relationship.

Now...

She's about to start licking.

That's right.

Tamamo-no-Mae is just that realistic.

"I have some important news that I wanted to share with you first."

Tamamo-no-Mae was extremely respectful, and a solemn expression appeared on her exquisite face, which was dotted with a vermilion dot.

"Recently, many powerful evil spirits in the Otherworld have disappeared."

Upon hearing this, Ye Xing frowned slightly.

"So, they all came to the real world through the 'door'?"

Tamamo-no-Mae pursed her lips and smiled gently.

"You are truly exceptionally intelligent, so quick..."

"BYD is just bragging, isn't it?"

Before Tamamo-no-Mae could finish speaking, Yohoshi interrupted her.

"Disappearing from the inner world means you've come to the real world, of course. Where else could you go? Are you trying to fool me?"

"Forehead..."

Tamamo-no-Mae never expected that the other party would be so firm in the face of such praise from a stunning beauty like herself.

whispering sound.

What an extraordinary character.

Tamamo-no-Mae didn't dare to provoke the other party, and could only force a smile.

"Um... I just wanted to remind you that with so many powerful evil spirits appearing in the real world at the same time, I think they are most likely targeting you and the people around you."

Upon hearing this, Ye Xing pondered for a moment.

Only a handful of people accompanied me to the Otherworld.

Miko Yotsuya, Rio Futaba, Yui Yuigahama, Mai Sakurajima, and Hina Amano, who was caught up in the battle last time.

There are five members in total.

"Since you've taken the risk and voluntarily appeared here..."

Ye Xing looked at Tamamo-no-Mae and smiled.

"So you're here to offer me a solution, right?"

"That is exactly what I was thinking."

Since she had decided to show goodwill to Yoruhoshi, and hoped to gain his protection someday in the future when danger struck, Tamamo-no-Mae held nothing back.

She suppressed her smile and spoke slowly.

"I believe... if you wish to protect those who came to the underworld with you and became targets of evil spirits..."

"How about we sign a contract with them, granting them the right to summon you in times of life and death?"

Upon hearing Tamamo-no-Mae's words, Yoruichi's eyes remained unmoved, and he simply asked in return with a calm expression.

"I am human, and humans cannot form contracts with each other, right?"

This is the fundamental principle of contracts.

Between humans, it is impossible to enter into a contract that is so binding that there will be consequences for breaking it.

Only humans and spirits, or spirits among spirits, can accomplish this.

Of course, there is a premise to this.

Ordinary humans cannot observe "spirits," and to sign a contract, one can only do so with those yokai that possess physical forms, such as the Nura Clan.

simply put.

As a psychic, Ye Xing should be unable to form a contract with those five members.

"is it?"
