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

Hiratsuka Shizuka gritted her teeth, looking so angry she couldn't speak.

Then, Ye Xing added another sentence that made her furious.

"Besides, their targets are young girls, young girls, understand?"

"Old woman, don't try to act young."

........

That night.

"sorry for disturbance."

Seeing Yukino Yukinoshita enter the room with an unusually reserved and cautious demeanor, Yohoshi asked curiously.

"Who are you greeting?"

"Eh?"

Yukino paused for a moment, somewhat surprised.

Where are your parents?

"died."

Yukino was taken aback for a moment upon hearing this, and then waved her hands repeatedly.

"Sorry, I..."

Before she could finish speaking, Ye Xing exclaimed in shock.

"So it was you who killed them?"

"Uh... how is that possible?"

"whispering sound."

Ye Xing instantly changed his expression and waved his hand.

"You didn't kill him, why are you apologizing? Please sit down."

"okay."

Let alone visiting the home of a boy of the same age.

Yukino Yukinoshita has no friends and has never been to anyone's house. Now that the two of them are alone together, even with her aloof personality, she can't help but feel a little nervous.

Ye Xing didn't seem to care, after all, he had lost count of how many girls had come to his house.

"By the way, Yukinoshita-san."

Hearing him address her as he addressed her again, and then revert to his usual way of addressing her, Yukino felt a strange sense of loss, but she maintained a calm expression on her face.

"what happened?"

"Since I promised your mother that I would protect your safety, I must let you know about the investigation I am currently conducting."

"investigation?"

Upon hearing those two words, Yukino suddenly felt a sense of foreboding and hesitated.

"Could it be... the case of the Teru Teru Bozu killer?"

Night Star laughed.

"Hey, your intuition is pretty accurate."

"What do you mean by 'approved'?"

Yukino replied irritably, her brows furrowed slightly.

"Yoru-hoshi, that's a serial killer that even the Metropolitan Police Department couldn't catch. Putting aside whether you can track him down, even if you do, it will only bring danger to yourself."

"Is it dangerous...?"

Upon hearing this word, Ye Xing shook her head as if she had heard something amusing and said softly.

"If there really are gods in this world, that serial killer had better start praying now."

Yukino asked instinctively.

"why?"

Ye Xing gave a kind smile, his eyes revealing excitement.

"Because I want an extra meal."

Immediately afterward, before Yukino, who looked puzzled, could speak, Yohoshi continued on her own.

"I'm not asking for your consent; I'm just informing you that the investigation I'm about to conduct is about that serial killer."

"You can choose to participate or not."

Yohoshi looked directly into Yukino Yukinoshita's eyes and spoke slowly.

"Of course, if you decide to participate, and demonstrate during the investigation that you are qualified to become a member of the Superpower Society..."

"Then you will have the same right as your sister, Yang Nai, to know the truth of this world."

158. Overpower Society's on-site investigation: Twisted and insane souls.

Upon hearing her older sister Yukino's name, Yukino's expression clearly changed.

Just as Haruno appears indifferent on the surface, she actually cares deeply about her younger sister Yukino.

As the younger sister, Yukino's feelings for her older sister are very complicated, but one thing is undeniable.

Although she didn't want to become Haruno, she also admired Haruno, who could solve everything smoothly and possessed outstanding talents.

Yukino had always had a question in her heart.

Why did my older sister, with her personality, become lovers with my classmate, Ye Xing?

How did the two of them meet?

Not only Yang Nai, but even her own mother, when speaking to Ye Xing, treated her differently than she would treat ordinary people. It wasn't like a superior treating a subordinate, but rather an equal negotiation.

The truth of the world?

Yukino felt that she was just one step away, just one last piece of the puzzle, to put everything together.

"What you described are qualifications sufficient to become an insider..."

Yukino asked in a calm tone.

"what is this about?"

Ye Xing waved his hand dismissively and replied.

"That's something you need to demonstrate to me during the investigation process yourself."

Yukino's eyes seemed conflicted. She raised her hand to tuck a strand of black hair behind her ear, silently pondering the situation.

It is certain that this Supernatural Quantum Mechanics Research Society is not as simple as I initially imagined.

What is the true goal of this organization?

What role does her older sister, Haruno, play in all of this?

In the end, Yukino made up her mind.

"I can assist with your investigation."

But then, Yukino's expression turned very serious, and her tone became extremely earnest.

"But you have to promise me that during the investigation, you won't do anything dangerous that could get you into trouble. Even if you do manage to find out the identity of that teru teru bozu killer, you'll immediately notify the Metropolitan Police Department and hand these matters over to professionals, okay?"

Hearing this, Ye Xing chuckled and teased.

"Yukinoshita-san, are you worried about my personal safety?"

Unexpectedly, Yukino Yukinoshita only hesitated for a moment before nodding and admitting it directly.

"um, yes."

Noticing Yosei's slightly strange gaze, Yukino blushed slightly, turned her head away, and maintained a calm tone, but her voice was somewhat nervous and hesitant.

"Please don't misunderstand, I just feel that this club exists because of you."

"You also told my mother that this club is an important reason why I was able to stay at Zongwu High School."

“I don’t want to transfer to the private Shujiwon Academy, so this club must continue.”

"It's not out of personal concern. I... I just want to stay at Soubu High School. Don't overthink it."

Faced with Yukino's several explanations, Yohoshi simply replied with a single word in that familiar, dismissive tone, drawing out the last syllable.

"Step~"

"You guy..."

Yukino gritted her teeth and glared at Yoruhoshi with resentment, thinking to herself that Yoruhoshi's calm reaction made her look like she was trying to hide something.

Just as she was about to say something, a very soft voice rang out in the living room.

"Goo~"

Upon hearing this voice, Yoru looked at Yukino, whose face was flushed and who seemed quite embarrassed, and laughed.

"Hungry? Let's go out and buy something to eat."

"...good."

Yukino stood up and followed Yoshihoshi to the entrance. She noticed a can of Pepsi and a crystal ball that, while not very expensive, was quite beautiful on the cabinet next to her.

"This can of Coke...was from the first day of school..."

Halfway through her sentence, Yukino realized she had misspoke and immediately shut her mouth.

Unfortunately, Ye Xing was an extremely perceptive person who immediately discovered her weakness and delivered a fatal blow.

"So, Yukinoshita-san, you've been secretly observing me since the first day of school?"

Yukino gave a soft hum and said indifferently.

"I just have a habit of observing everyone around me."
