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

According to the information sent by Yotsuya Miko, monsters like the Ushi no Toki have appeared, which have merged with human bodies and can ignore the laws of "observation" to slaughter humans at will.

What should I do?

Before Yoruichi leaves the Otherworld, should we just passively defend ourselves and let the other party move freely in Kyoto City?

"Chief Yagami."

Rio Futaba walked up to Souichirou Yagami and spoke softly.

"Please stay here with your officers and keep watch. If there are any unusual movements, please contact us via walkie-talkie."

"Okay, I see."

Souichirou Yagami nodded slightly and responded in a deep voice.

Rio Futaba and Mai Sakurajima left the power station and arrived at a secluded area several hundred meters away.

"Mai-senpai, Rio."

Seeing Mai Sakurajima and Rio Futaba, who were wearing masks, approaching, Miko Yotsuya initially wanted to stand up to greet them, but she frowned slightly and ultimately sat down on the ground, abandoning the idea of ​​standing up.

"See you."

Rio Futaba had known Miko Yotsuya the longest, and when she saw her slumped on the ground looking utterly helpless, she quickly stepped forward and asked anxiously.

"Are you alright? Should we go to the hospital?"

Yotsuya Miko patted Futaba Rio's hand and comforted her with a smile.

"I'm fine, it's just that I used up too much spiritual energy."

"That's good..."

Rio Futaba breathed a sigh of relief, a complex look appearing in her eyes, and couldn't help but mutter to herself.

"If that guy were here... just let him do *that* to you... and your power would be restored..."

"Please spare me!"

Yotsuya Miko pursed her lips, seemingly disagreeing with Futaba Rio's statement, and said with a slight blush.

"If I were to do *that* with him under these circumstances... I'd probably die..."

"That's true."

Mai Sakurajima walked up to Hina Amano, first observing her neck, arms, and other exposed skin before asking her questions with concern.

"Yin Cai, are you alright?"

"I'm fine~"

With a smile on her face, Hina Amano replied in a deliberately relaxed tone.

"I didn't use my own power, it's perfectly fine."

"That's good."

Looking at the exhausted-looking Miko Yotsuya, and remembering the dangerous situation she had just faced, almost dying, even the usually rational and calm Rio felt a surge of intense anger.

"What's the next step? Have you obtained any intelligence?"

Yotsuya Miko mustered her spirits and replied.

"Those strange doors shouldn't appear again anytime soon."

Immediately afterwards, Miko Yotsuya responded to what had happened at the power station, looking thoughtful with a slight frown.

"Judging from the appearance of that Ushi no Toki woman, she probably knew that there would be such a door that could cause an earthquake in that power plant."

"Even if it thinks that Hina and I don't have the power to close that door, if it were me, I would definitely make sure to kill the enemy, or use myself as bait to lure the enemy away from where the door appears. That would be the safest method."

At this point, Miko Yotsuya's golden eyes flickered as she slowly began to speak.

"This might be the enemy's weakness."

Rio Futaba instantly understood what Miko Yotsuya meant, and said thoughtfully.

"You mean... the disaster that caused the earthquake, the massacre of a large number of humans, and the creation of powerful evil spirits in the underworld to kill Night Star, who was trapped there. Because the evil spirits merged with humans, they possessed a high degree of intelligence, so they valued their own safety more than achieving their goals?"

"exactly."

Yotsuya Miko's golden eyes flashed with undisguised killing intent as she spoke softly.

"Since they are different from ordinary evil spirits and possess emotions like fear, then... taking the initiative is the best option."

"Take the initiative?"

Upon hearing this, Mai Sakurajima frowned slightly and hesitated.

"But...wouldn't that be too dangerous?"

"There is definitely danger..."

Rio Futaba appears to have agreed with Miko Yotsuya's proposal.

"If we hold our ground at the power station, we will be facing the evil spirits of the entire city of Kyoto. We don't know how many evil spirits the enemy can control. Although they are just ordinary evil spirits, we are not Night Star after all. We can't fight and replenish our strength by devouring them. There is a limit to how much we can do."

"But if we choose to take the initiative, as Miko said, since those monsters that have merged with humans have feelings of fear and self-preservation, they will definitely gather all their strength to protect themselves when they are threatened."

"Moreover, ordinary evil spirits cannot interfere with reality, nor can they directly attack ordinary humans. The only ones who will face these guys are us psychics. It is not wise to sit in the power plant and wait for the enemy to summon more evil spirits to launch an attack."

"Taking the initiative and constantly moving around will prevent those guys from having time to destroy the power station or gather the evil spirits in one place to launch an attack. This will minimize our numerical disadvantage and is indeed the best solution."

Yotsuya Miko also stood up and slowly began to speak.

"Ye Xing said that evil spirits are just prey, and the initiative in the battle is in the hands of us psychics."

Since both Miko Yotsuya and Rio Futaba had given the same opinion and given their reasons, Mai Sakurajima naturally wouldn't refute it.

"In that case, let's hand over the Metropolitan Police Department walkie-talkie provided by Chief Yagami to Yui and the others. If we are to start the hunt, we must maintain contact with each other, which is one of our advantages."

...........

Half an hour later, in the other side of the underworld.

Tamamo-no-Mae stroked her smooth, flat abdomen, still looking somewhat incredulous, as if she were in a dream.

Of course, her action was not because she was full.

That's not where it was poured.

Tamamo-no-Mae was simply surprised.

Such a severe injury, even for her, would be irreparable and fatal, yet she could recover instantly simply by swallowing it?

Moreover, Tamamo-no-Mae could clearly feel that her strength had become stronger than before after swallowing the milk.

Wait a moment...

milk?

So, the milk that Hachiko was referring to as the most delicious-tasting milk in the world was this!?

Tamamo-no-Mae blushed slightly, thinking to herself how naive she had actually thought the milk the other person was talking about was just plain milk.

She looked at Ye Xing, who was resting against the wall of the teaching building corridor, and noticed that his arm had not yet recovered. She couldn't help but look worried.

"Mr. Night Star...is your arm... beyond repair?"

"It's not that it's beyond repair."

Ye Xing replied nonchalantly with her eyes closed and a lazy, flippant air about her.

"I just merged with the Pale Ghost Hand, used my domain expansion, and used all my spiritual power to attack that evil spirit with compressed pure evil spirit power. Now I don't have a single bit of spiritual power left in my body. It will take at least a day to recover to normal and reshape my right arm."

At this point, Yoruhoshi opened his eyes, pointed to Onimaru Kunitsuna beside him with his sword broken, and smiled at Tamamo-no-Mae.

"Including Onimaru Kunitsuna, he will need a few days to recover. Until then, I entrust him to protect me, an ordinary human being, in this perilous underworld."

"you..."

Upon hearing this, Tamamo-no-Mae hesitated, her expression turning somewhat uncertain.

"Why would you risk all your spiritual power? That's far too risky..."

"Adventure? No, no, no."

Yoru no Hoshi completely disagreed with Tamamo-no-Mae's opinion.

"In that situation, it would be foolish not to go all out."

“Once I lose control of the domain, that evil spirit will likely connect with the black mist, gaining the ability to draw power from it and resurrect itself continuously.”

"Therefore, I must completely destroy it within the domain that can sever its connection with the outside world. Before I consume too much power to maintain the domain's expansion, I must concentrate all my power to unleash the strongest attack. This is not risky, but rather prudent."

Tamamo-no-Mae nodded noncommittally without replying. Instead, she looked at Onimaru Kunitsuna, who was lying quietly on the ground with several deep nicks on his sword, and Yoru, who was sitting and resting against the wall with his right arm empty. A complex look flashed in her eyes.

What the other party said is probably correct.

Tamamo-no-Mae knew very well how terrifying the power of that enormous evil spirit, formed from humanity's fear of earthquakes, was.

Even when she was almost back to her peak condition and had unleashed her true soul form, she was still completely crushed in front of that monster.

Night Star did win, but it was clearly not an easy victory.

The other person is just an ordinary human being, and even in this perilous underworld, does he need my protection...?

Tamamo-no-Mae realized something.

The opponent's milk alone was enough to boost my strength by a level while I was recovering from my injuries.

if...

Why not just devour the other's flesh and blood directly?

Ye Xing is currently in poor condition.

The Onimaru Kunitsuna, being a spirit creature, had clearly reached its limit and no longer had the strength to protect its master.

Thinking of this, a resolute look appeared in Tamamo-no-Mae's eyes. She finally made up her mind, stood up abruptly, and walked quickly to Yoru-no-Shi.

She pursed her lips and slowly began to speak.

"Yexingjun."

"how?"

"I wish to... amend the contract between us."
