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

After Hiratsuka Shizuka left, Yuigahama Yui watched Yohoshi open the door, seemingly not intending to invite Yukino in, and couldn't help but tug at her sleeve, whispering.

"Well, why don't you talk to Yukino first? I'm begging you."

"Since it's your request, then let's hear it."

Yoruhoshi looked at Yukino Yukinoshita standing there and said in a flat tone.

"Since Yui has said so, you may come in."

Yukino Yukinoshita frowned slightly, feeling somewhat uncomfortable.

Judging from this, the other party seems quite impatient?

Normally, given Yukino Yukinoshita's proud personality, she would have turned and left long ago.

But today, she really didn't want to wait a moment longer.

"Thank you, Yui."

Upon hearing Yukino Yukinoshita say those words in a very awkward tone, Yui Yuigahama patted the back of her hand and smiled sweetly.

"Don't mention it, we're friends."

"friend..."

Yukino Yukinoshita did not deny it this time, but simply nodded.

"Well, we are friends."

.......

After entering the room, Yukino Yukinoshita sat on the sofa, glanced at Yui Yuigahama sitting next to her with a blank expression, and looked like she wanted to say something but couldn't.

Seeing this, Ye Xing waved his hand casually.

"Just say it."

"Well."

Yukino Yukinoshita straightened the hem of her skirt, tidied her long black hair by her ears, looked directly into Yohoshi's eyes, and spoke slowly and deliberately.

"You are the 'mask'."

Yukino Yukinoshita kept her eyes fixed on Yohoshi, taking in any flaws that appeared on Yohoshi's face immediately.

To her surprise, the other party simply nodded indifferently.

"Yeah, what's wrong?"

"Eh?"

Seeing that Yohoshi had actually admitted it, Yukino Yukinoshita was taken aback and hesitated.

"You...you actually admitted it?"

"Why not?"

Seeing that Yohoshi still seemed completely unconcerned, as if it were no big deal, Yukino Yukinoshita couldn't help but glance at Yui Yuigahama standing to the side.

She noticed that her friend, the only one she could call a friend, Yuihama, showed no surprise or shock on her face.

"It seems you already knew."

"Um... I'm sorry, Yukino."

Yui Yuigahama smiled sheepishly, trying to get away with it by being cute.

"Ugh..."

Yukino Yukinoshita sighed helplessly and murmured.

"Actually, I roughly guessed it, after all, you joined the club a long time ago, and you're always present at every internal meeting..."

At this point, Yukino Yukinoshita paused and looked at Yohoshi.

"So, those so-called insiders are actually people who know your true identity. If I'm not mistaken, the other three unidentified people who appeared on the live TV broadcast last time when I went with you to hunt down the Teru Teru Bozu killer, judging from their height and posture, should be Futaba, Yotsuya, and Mai-senpai."

Ye Xing nodded and smiled.

"As expected of Yukinoshita, her observation skills are truly remarkable."

Yukino Yukinoshita's special talent lies in her keen observation of her surroundings.

Hiratsuka Shizuka believes that Yukino is just as intelligent as Haruno, but her view is actually too one-sided.

Yang Nai excels at understanding other people's thoughts and negotiating with the most appropriate words and demeanor.

Yukino, however, is not good at understanding other people's thoughts; she simply observes from an outsider's perspective.

That's why she actually noticed it when she was watching the recorded live broadcast.

Although their voices, outfits, and masks were different.

However, the tone and posture of "Mask" when he spoke, and the feeling he gave off, were completely consistent with Ye Xing.

Even though the other three didn't speak, their standing posture and height matched the characteristics of Mai Sakurajima, Miko Yotsuya, and Rio Futaba.

Of course, Yukino Yukinoshita didn't think she had accomplished anything particularly remarkable in her deduction.

In fact, Night Star had already given her enough clues and hints.

If you approach a question with the answer already in mind, you will naturally arrive at the answer you already knew.

"so..."

After a long silence, Yukino Yukinoshita finally spoke slowly.

"now what?"

"Now?"

Ye Xing stood up, extended his right hand to her, and smiled as he spoke.

"Welcome to my harem... our Xyz Club."

Yukino Yukinoshita frowned slightly: "You were just... talking about a harem, weren't you?"

"That's not true. You can't make false accusations against your brother-in-law, Yukino."

"Hmph, what brother-in-law? Don't try to take advantage of me here."

Despite her sharp tongue, Yukino Yukinoshita stood up and extended her right hand to gently shake hands with Yohoshi.

"In that case, I'll leave first."

After saying this, Yukino Yukinoshita glanced at Yui Yuigahama with a complicated expression, and then left the room.

She knows what she's good at and what she's not good at.

That is, handling interpersonal relationships.

Yukino Yukinoshita doesn't quite understand the relationship between Yohoshi, the members of Xyz Society, and her older sister.

Why could he call himself Yuihama's brother-in-law in front of her, and Yuihama didn't seem to have any objections?

Is it possible...

Is this the "real thing" I've been searching for?

That's absurd, how could that be?

Doesn't that mean that if I want to touch the "real thing," I also need to...

Impossible, absolutely impossible.

Yukino Yukinoshita secretly made a vow.

There is absolutely no way I would join any harem.

In that case, we might as well change the name to Yukinoshita Mushino.

.......

After Yukino Yukinoshita left, Yui Yuigahama breathed a sigh of relief and looked at Yohoshi with a pout.

"I'm telling you, isn't your attitude towards Yukino a bit too rude? After all, you're friends from the same club, and you're not incapable of speaking properly."

Night Star replied confidently.

"If I'm gentle to everyone, then it's the same as not being gentle to anyone, and that gentleness would be meaningless, wouldn't it?"

"Forehead..."

Yui Yuigahama pondered for a moment, thinking to herself.

This seems to be the case.

If Ye Xing were usually gentle and considerate, I wouldn't have been so moved by what she said while I was shopping.

Does being gentle to everyone mean being gentle to no one...?

"and many more."

Yui Yuigahama belatedly realized what was happening and stared at Yoru with a slightly resentful look, like a cat whose tail had been stepped on.

Are you implying something to me?

"As long as you can understand it."

"Hmph...but..."

Yui Yuigahama blushed slightly and muttered softly.

"I've never been gentle with any other guy..."

Immediately afterwards, she adjusted her mood and sorted out her thoughts.

"Alright, let's get down to business. What is the fastest way to increase your strength...?"

"It's definitely the bottom line."

Yoruhoshi first said something that Yui Yuigahama couldn't understand, something that seemed to contain some deeper meaning, and then said seriously.

"Before I begin my explanation, there are a few things to note."

"Any other precautions?"

Upon hearing this word, Yui Yuigahama straightened her posture, her curiosity growing stronger.
