I, the Rock King Emperor with 21 billion in power, have joined the chat group.

"Oh." The fat, pig-like man nodded, and grunted in a muffled voice, "What is it?"

"As neighbors from now on, I look forward to your guidance." Kazuya Mitsuya said the usual polite words and presented the small gift box in his hand.

"Oh, I see." The man took the gift box, grunted impatiently, and quickly retreated back into the house, slamming the door shut.

Outside the door, Kazuya Mitsuya's brows furrowed even more. He seemed to have faintly heard cries for help and groans coming from inside the house, and the fat, pig-like man reeked of a mixture of male and female bodily fluids that was almost nauseating.

Should we call the police?

But he didn't listen that carefully.

If it's a mistake, it will embarrass him greatly.

Let's try again.

Having made this decision, he quickly rang the doorbell again.

About a minute later, the door opened, and a charming young woman peeked out, revealing only her head.

She looked at Kazuya Mitsuya, her voice as soft as dripping water: "Um...is there anything I can help you with?"

Kazuya Mitsuya smelled the strong odor again, and it was very close.

He immediately understood the woman's situation, blushed, and quickly handed her his business card.

At the same time, she quickly said, "Your husband opened the door just now, right? I forgot to introduce myself. This is my business card. You can ask me for help if you have any medical questions in the future."

The young woman's body trembled slightly, and she let out a soft moan: "Mmm...it's my husband, I know."

"Alright, I won't bother you any longer." Kazuya Mitsuya fled as if escaping, quickly heading towards his next neighbor's room.

About an hour later, he had finished distributing the gifts and business cards. Apart from room 1407, which had an unexpected incident, the other rooms were all normal.

However, one thing is rather strange: all the people who opened the door were either young and beautiful women or vibrant young girls; no men ever appeared.

However, Kazuya Mitsuya considered that today was a workday, and other people's husbands and fathers might not have come home from get off work yet, so it was also possible that all the people at home were housewives.

Kazuya Mitsutani noted this down in his notebook, which was used to record unusual occurrences in his surroundings. The world he had transmigrated to was truly strange; he dared not be negligent in the slightest, lest he be captured by some supernatural force and become a being stripped of all human dignity.

After delivering the gifts, Guanggu He rested for a while before leaving the room to go downstairs to find something to eat.

When he came upstairs, he saw a ramen shop on the commercial street downstairs that seemed to be one of his favorites. What a coincidence! He had to go and have a bite.

While waiting in front of the elevator, he saw a very unexpected person.

"Miss Yukinoshita?"

He looked at the aloof girl with surprise: "What are you doing here? Visiting relatives?"

Alone in the elevator, Yukino Yukinoshita stared in surprise at the man before her. She, who usually believed she would never be defeated by an accident, had for the first time the thought of running away.

"Hmm..." she mumbled, looking around aimlessly. Her long, dark hair swayed with her movements. Finally, she seemed to give up and turned her gaze to Guang Gu He Ye.

"Hello, doctor from Optics Valley."

She lowered her head, looking down at Guanggu Heye's chin and below, avoiding his eye contact, her voice as faint as a mosquito's buzz.

"I live here alone. What about you?"

"What a coincidence." Guangguang Guhe also noticed her unease. He wasn't the kind of person who would make others feel embarrassed, so he decided to quickly end the conversation: "I just moved into room 1405 today. We'll be neighbors from now on."

"I have something to do today, so I'll have to go now. Let's talk again when we have time."

Guanggu He quickly ended the conversation and stood inside the elevator.

"Um...um," Yukino Yukinoshita reacted a momentarily, but the next second she understood what Kazuya Koguchi meant. She nodded to him gratefully and then quickly left the elevator.

As the elevator doors were about to close, she seemed to realize what was happening, and her usual demeanor and state of mind at school quickly returned to her inner self.

When she looked at Guanggu Heye again, she was a little calmer—although she wanted to calm down completely, she couldn't help but blush whenever she thought of the warm palm that was swimming in her abdomen.

"Dr. Guanggu, I live in room 1046. You must be in the newly moved-in room 1045. I'll visit you with my sister when I have time."

"Ah."

Guang Gu He nodded, the elevator doors closed, and their eyes met.

Yukino Yukinoshita calmed herself down a bit. She really didn't expect to see this doctor at her rented place, which is why she was a little flustered.

For her, going to He Ye Na Hospital in Optics Valley was one of the few private things she wanted to keep from others.

Even with this panic, she managed to suppress it quickly with her strong inner strength.

Since she had already decided to become a real thing, she couldn't back down under these circumstances. Even if it was a treatment, it was just a normal treatment method, and she had no reason to be ashamed.

Yes, she has absolutely no reason to be shy.

To strengthen her resolve, she couldn't help but repeat the words to herself twice more before heading to her room, her ears still slightly warm.

Before she even reached the door, she saw the door to room 1047 next door open.

An obese man, who looked like a balloon, struggled to squeeze out of the doorway.

He squinted his small, beady eyes and looked at Yukino Yukinoshita with a hint of surprise, his gaze as greedy as a sticky slug, scanning Yukinoshita's body from top to bottom.

A few seconds later, he was panting heavily, a smug smile playing on his lips: "You're the resident of number 1046?"

Yukino Yukinoshita tensed up, her whole body trembling, and an indescribable fear welled up in her heart.

This prompted her not to answer the man's question, but to quickly close the door and leave his sight.

The fat, pig-like man saw that Yukino Yukinoshita didn't answer his question, but instead quickly closed the door and went inside. He narrowed his already small eyes in annoyance.

He walked up to Yukino Yukinoshita's door, brought his huge, fat face close to the pinhole, and whispered, "Hello, resident of 1046, are you there? Don't you know how rude it is not to answer people's questions?"

"Open the door and let's talk."

Yukino Yukinoshita was inside the house, but she didn't make a sound.

"Whew!"

She leaned against the door, breathing heavily.

Hearing that man's voice, the fear in my heart just wouldn't go away.

"cut!"

Seeing that she not only didn't open the door, but didn't even reply, the man at the door spat indignantly and swayed away from Yukino Yukinoshita's door.

"Who is that person?"

After the other person left, Yukino Yukinoshita, having gradually regained her composure, pondered the problem: "I remember that room 1407 was occupied by a young, independent female executive. How come he swaggered out of room 1407? Could he be that woman's boyfriend?"

"No way, such poor judgment? Or is that person a burglar?"

Thinking about this, Yukino Yukinoshita couldn't help but feel worried. If it really was a robber, then had the owner of house number 1407 already been murdered?

She should help them, but...

She looked at her trembling legs and realized that she couldn't muster any strength no matter what she did.

What should we do?

She forced herself to take her phone out of her backpack with trembling hands and dialed her sister's number.

The moment the call connected, she couldn't help but burst into tears.

"Sister, save me..."

........

Leaving Yukino Yukinoshita's sight, Kazuya Mitsuya touched his cheek, feeling somewhat wistful.

Who would have thought that someone as ordinary as Louis Koo from Tokyo would one day be on the guard of young girls?

What's more, the fact that she was once one of his two-dimensional waifus really frustrated him.

Taking advantage of his discomfort, he deliberately ate two large bowls of spicy tonkotsu ramen, swallowing all his frustrations along with the rich and fragrant broth.

Patting his stomach, feeling a sense of calm returning to normal, Kazuya Mitsuya got up and walked towards the building's property management office.

Now that we've arrived in this strange world, we must avoid ending up like the victims in NTX games, where their wives or girlfriends have become sex slaves without them even realizing it.

Kazuya Mitsuya aspires to become someone who carefully observes everything around him.

Today, since he sensed something was amiss in the apartment and saw the unsettlingly obese man in room 1407, he couldn't dismiss it as a trivial matter.

We must get to the bottom of this.

.....

“Mr. Kotani Kazuha, my name is Kurata, and I am one of the building's butlers. May I ask how I can help you?” Inside the property management office, a middle-aged man in a butler's uniform asked with a gentle smile, “We will be happy to serve you.”

Kazuya Mitsuya nodded and began to explain his reason for coming in a roundabout way: "As you should know, I just moved here today, so I wanted to learn more about my neighbors from you."

Butler Kurata naturally agreed with this question. "Please ask. Of course, if it involves the residents' deepest privacy, I'm afraid I can't help you."

"Of course, of course." Kazuya Mitsuya waved his hands and laughed, "I'm not a private investigator, and I don't have any ill intentions. Why would I ask too many private questions? Please rest assured."

"I just want to ask two questions. One is whether my next-door neighbor, number 1406, is currently unoccupied. A friend of mine saw my rented apartment and is also interested in staying here."

"I'm sorry." Butler Kurata bowed slightly and answered without hesitation, "Room 1406 is already occupied by a single girl."

"Oh well, that's a shame. What about number 1407?" Kazuya Mitsuya shrugged.

"There is someone, and she is also a single woman," Kurata the butler replied tactfully.

"Um????"

Section 0: Only I can save them (7)

The information that came from the butler Kurata was not unexpected for Kazuya Mitsuya.

That fat guy who looks like a pig doesn't look like a good person at all. He's just like the fat otaku protagonist who came out of one of those adult films made specifically for pornography.

Since the resident of number 1407 is a single manager of a large company, not young, and still unmarried, he is naturally very picky.

Therefore, this fat guy couldn't possibly be the boyfriend of resident number 1407.

Therefore, there is only one possibility left: the woman in case 1407 was coerced in some way, forcing her to submit to Fatty's threats when Kouya Kazuya knocked on the door, thus covering for him.

If this were an ordinary world, Guanggu Heye would probably have already called the police. But this is a special world with supernatural powers, and no one knows what other strange things there are besides the Demon Ninja.

Therefore, Guanggu He also decided to observe for a while longer.

“Mr. Kurata.” Mitsuya Kazuya pretended to be concerned, stroking his chin as if hesitating whether or not to speak.
