In the Multiverse, I Only Get Stronger by Taking Wives

Goto Nijika, though just an elementary school student, had far better social skills than her older sister and was very lively and cheerful.

"Honey, shouldn't we take our child to see a doctor?" Goto's mother quietly said to her husband beside her.

"We've already plastered her room with talismans, but it still doesn't seem to be working," the old father said, also looking worried.

"How about we hire an Exorcism Master?" the mother asked.

"I think we should also get a psychologist," the father nodded.

"Well, Big Sis must have encountered something happy at school," Goto Nijika said. "Like, suddenly someone showed her some casual concern, or she wasn't forgotten when they were handing out chocolates to everyone at a festival."

"...Would something like that be worth being so happy about?" the old father remained troubled.

"Poor child," the old mother wanted to cover her face and weep.

"In any case, it's impossible for Big Sis to make new friends."

Goto Nijika, being young and innocent, spoke words that were like critical hits. Goto Hitori had often been stabbed in the heart by her own sister.

At this moment, Goto Hitori finally snapped back to reality and heard her sister's words.

"Hmph, hmph, my foolish sister."

Unlike before, when she would be dejected or furious after being hit by critical blows, Goto Hitori instead let out a cold laugh. She propped her forehead with one hand, a mocking smile forming on her lips, possessing a bit of the chuunibyou flair of a major villain.

"Your Big Sis here, you know, didn't just make friends," Goto Hitori said proudly. "Not friends, but a boyfriend."

"A boyfriend!"

She suddenly stood up, hands on her hips, looking down at everyone in the house.

At this moment, Goto Hitori was like a general returning victorious, making the little dog cowering under the table tremble in fear.

"Really? Big Sis is lying," Goto Nijika said, still smiling like a flower.

"This time it's real, Big Sis has truly escaped singledom and transitioned from a shut-in to a normie!" Goto Hitori declared.

However...

The gazes of the entire family converged on her, followed by a long silence.

"Um... isn't that one of the three great illusions in life?" the old father tried to analyze. "Like, a guy approaches you, helps you, and you think he likes you?"

"No, no, it's a real boyfriend!" Goto Hitori emphasized. "He confessed to me!"

Old Mother: ...

Old Father: ...

Goto Nijika: Big Sis must have been confessed to while someone else was playing 'Truth or Dare'!

"Really, really, it's true! Sigh... I don't know how to explain it to you all, but from now on, I am no longer single!" Goto Hitori said, a little anxiously, stomping her foot.

This was a rare thing to brag about, so why were her family members reacting like this? Where would that leave her vanity!

"Honey, I think we should still take this child to see a doctor. Because she's too lonely, she's developed delusions," the old mother said with a sad expression.

"I'm sorry, Hitori, it's our fault for not taking good care of you," the old father was also on the verge of tears.

"Big Sis... I'm sorry. I spoke too harshly before and didn't consider your feelings."

Goto Nijika, now at an age where she could be sensible, also showed a sad expression.

"Aaaahhhh! I really have a boyfriend! Why don't you believe me!"

Goto Hitori was speechless.

"Honey, I'll make a doctor's appointment," the old father said.

"Yes, and I'll book an Exorcism Master too," the old mother added.

"Big Sis, you need to take care of yourself and be strong," Goto Nijika took her sister's hand. "You'll get better."

Even the little dog, who couldn't speak, showed a worried expression.

Goto Hitori: "..."

Why doesn't anyone believe me? Goto Hitori was utterly helpless.

Fine, I'll bring my boyfriend over another time and see if they still don't believe me then!

Tsukikawa Shu also returned home.

He tossed his schoolbag onto a chair, then lay down on the soft bed and looked at his phone.

He had a house, and both parents were busy. The only downside was the lack of a sister.

He logged onto various relevant forums and opened his browser, browsing information about the Inner World.

Indeed, many people were posting threads detailing the situation and dangers of the Inner World. Judging by the number of posters, it wasn't a small number.

Some people were also sharing their experiences.

"If you get transported to the Inner World, I suggest you find a safe place and hide. This time, our mission was to survive for three days. I just starved through it. Suffering from hunger is better than dying in the mouths of those monsters."

"I agree with the person on the road. If possible, find a place with plenty of food to hide. I never thought that in the 21st century, I'd experience a great famine. On the third day, I looked at my own excrement and thought it was a delicacy."

"I couldn't stand it, but I didn't dare to go out, so I had to survive on my own waste QWQ."

But some people also raised objections to this post.

"Do you guys really think you can survive by hiding? I'm telling you, killing other players gives you experience points. Be careful you don't get opened up while hiding in your rooms."

"Yeah, yeah, especially places like the restaurant. It's fine for collecting food, but it's definitely not a place for weaklings like us to hide. Watch out for those guys who specialize in hunting players coming in and taking everyone out in one go!"

And as Tsukikawa Shu had predicted, many of these people were looking for a safe place to hide, and they even shared a lot of tips for doing so.

He flipped through them but couldn't find anyone teaching others how to deal with the monsters.

This was also normal. Once people entered the Inner World, their true nature would be exposed. Resources were limited, and those capable of hunting monsters wouldn't want to create more competition for themselves.

On the contrary, these weak players were quite good sources of experience points.

In addition, there were quite a few people pretending to be players who had entered the Inner World, just making up stories.

For example, they claimed you could find help from certain associations in the Inner World, or that you could find weapons in specific fixed locations, basically just making things up.

But it could be foreseen that these fabricated stories would mislead many newcomers when the Inner World opened for the second time.

This also showed that, apart from those who had truly entered the Inner World, everyone else didn't believe such a space-time existed at all.

"System, what kind of people are chosen to enter the Inner World?" Tsukikawa Shu asked.

[The selection rules for the Inner World are: 50% random selection, and 50% are people related to players who have already entered the Inner World.]

"There's a 50% chance of people around me being teleported in, which is indeed uncontrollable."

After that, Tsukikawa Shu opened the system interface again.

[Number of marriages you have formed: 1]

[Destiny Partner: Goto Hitori]

[System Rating: S]

To have a destiny partner rated S-class by the System, it seemed the rewards would be good.

He had already gained enough experience, resources, and weapons from his first entry into the Inner World, more than he could ever use.

"All of this can serve as capital for gathering a virtuous wife."

Tsukikawa Shu pondered, beginning to plan his wife-taking strategy.

Of course, he also had to do his homework regarding Goto Hitori.

After scribbling on a piece of paper for a while, Tsukikawa Shu stretched. The night was getting late, so he went out to buy ingredients for dinner.

He cooked the meal at home, plated it, and even made an extra portion, sealing it in a plastic container.

He went out again and came to the door of his next-door neighbor.

The sound of electronic game fighting could be heard from upstairs, along with a sweet, childish voice excitedly shouting.

"I am the Demon God! I am the Demon God!"

Tsukikawa Shu knocked on the door.

"Ah!"

The girl upstairs clearly hadn't expected anyone to come over at this moment, and the sound of the electronic game abruptly stopped.

After a moment, the door opened just a crack, revealing pink and white hair with a cowlick, wearing a loose white shirt, and two light red eyes warily looking at Tsukikawa Shu outside.

There is an illustration here, which can be viewed after updating the version.

"Has Mihari not returned yet?" Tsukikawa Shu smiled.

This girl was Ouyama Mahiro, and she had a younger sister named Ouyama Mihari.

Well... if she was still considered a sister now.

According to the plot of the anime Onimai: I'm Now Your Sister!, Ouyama Mahiro had already been tragically ambushed by her own sister.

Unsportsmanlike, she came to deceive and sneak attack! This classmate in her twenties.

Then, Ouyama Mahiro turned into a loli with a soft voice and a soft body.

Now it seemed Ouyama Mihari was more like her older sister.

Tsukikawa Shu wanted to advise the young people of today to behave themselves and not engage in internal strife all day long!

Ouyama Mahiro was a severe shut-in, her only companions being various sugary drinks and games, a perfect example of a homebody.

If she met Goto Hitori, the two might actually get along, as both were shut-ins.

However, Goto Hitori could also play the guitar and had a high online popularity, allowing her to earn income from advertisements, while Mahiro was just a shut-in.

Ouyama Mahiro timidly shook her head, clearly still a bit afraid of Tsukikawa Shu.

If Tsukikawa Shu wasn't her neighbor, Ouyama Mahiro wouldn't have opened the door at all; she was extremely socially anxious.

Ouyama Mihari was a very intelligent girl, now a university student who skipped grades, and was currently in a higher grade than Ouyama Mahiro.

Ouyama Mihari had already started researching drugs, and this was the time she was scheduled to return to the lab to report her progress, leaving Ouyama Mahiro alone at home.

"Have you eaten?" Tsukikawa Shu asked.

"No..." Ouyama Mahiro paused, then said in a soft voice, "...I'm eating instant noodles tonight."

"I don't believe that. How can you eat instant noodles every day?"

Tsukikawa Shu picked up the lunchbox and brought it to Ouyama Mahiro, who was behind the door.

"I made an extra portion."

"Waaah..."

Ouyama Mahiro instinctively flinched and wanted to refuse, but Tsukikawa Shu's cooking was good, and she twitched her nose. She hesitated.

Tsukikawa Shu directly shoved the lunchbox into her arms.

"I'll be making extra for the next few days, so I'll make one for you too," Tsukikawa Shu said.

"Th-thank you..."

Ouyama Mahiro glanced at Tsukikawa Shu before shyly saying.

"Alright then, I'm leaving," Tsukikawa Shu smiled and left his neighbor's doorway, returning to his own home.

Ouyama Mahiro watched Tsukikawa Shu walk back into his house with her eyes before slowly closing her door.

A moment later, the sound of video games could be heard again from upstairs in the neighbor's apartment.

"I should introduce Goto Hitori to her in a few days. They'll probably have a lot to talk about. It's not good for her to be cooped up at home all day."

Tsukikawa Shu looked at the light from the opposite room and shook his head helplessly.
