From Warhammer to Hyperdimensional Harem

Saori Makishima was the administrator of the online community "Otaku Girls Unite!" with the screen name ID "Saori Bajina."

The surname "Bajina" in her name was taken from the character Quattro Bajeena from "Mobile Suit Zeta Gundam."

So Saori Makishima was a Gundam fan.

Black Cat was a netizen she had befriended, also a two-dimensional culture enthusiast, whom Saori had personally sought out.

Then, Black Cat had suddenly released an incredible video.

It was hard to imagine that with Black Cat's capabilities, she could obtain such footage.

It wasn't that Saori looked down on Black Cat, but this clearly wasn't something an ordinary person could get.

And then what did Black Cat do right in front of her?

After closing her eyes, Black Cat reopened them and stared at her laptop computer, and an icon mysteriously appeared on the desktop.

Opening it revealed a folder with videos that had appeared out of nowhere.

How was this possible?

Don't say Black Cat had some hacking abilities—this didn't look like hacking at all, more like supernatural powers.

Looking deeply at Black Cat, seeing her small face breaking out in sweat, Saori pushed up her glasses.

"Black Cat, did you perhaps gain some kind of system like in novels?"

After this playful question, Black Cat's reaction was interesting—she couldn't make eye contact anymore and became evasive.

"Th-that, this is actually me using... um, that. Yeah, I secretly used a special software to pre-send it to your computer, Saori, then..."

"Black Cat, saying these things, don't you think you're being way too guilty? Your tone isn't even smooth. Besides, what if I asked you to demonstrate it again?"

"Ugh—"

"What system is it?"

Saori moved her face closer, making Black Cat completely look away.

"By the way, you once discussed something called the 'Interdimensional Channel' with me."

Saori remembered one day when Black Cat had discussed what seemed like very chuunibyou topics with her. They'd discussed such things before, but that day's discussion felt somewhat strange.

So saying this, Saori noticed Black Cat's small body stiffen severely, her face already covered in waterfall-like sweat.

She'd hit the mark!

Was this really real?

If what Black Cat said about the "Interdimensional Channel" was true, this was too incredible.

"So this video was sent to you by that interdimensional netizen, right?"

Faced with Saori's inquiry, Black Cat pressed her lips tightly shut and responded with silence.

The reason she had told Saori about the "Interdimensional Channel" in that hypothetical "I have a friend" series was because Black Cat had really thought her chuunibyou had gotten so bad that her brain was malfunctioning, so she'd confided in Saori.

"So, Black Cat, are you planning to use works from other worlds and publish them in this world? Become a content creator?"

"No."

"Hmm?"

"Let me calm down first."

"OK."

Black Cat took a deep breath and exhaled. Continuing to play dumb was useless now.

"Saori, can I trust you?"

Black Cat said very seriously.

Although she was still a middle school student, she already understood that some problems weren't something a middle schooler could handle well.

"Do you think I'm untrustworthy?"

"I trust you."

"Then trust me. Come on, let's find another place. Let's go directly to my house!"

"Mm."

In the blink of an eye, Black Cat and Saori had taken a taxi to an upscale residential area, arriving at a three-story building.

"Don't be nervous or restrained. I live here alone."

"You live alone?"

Black Cat was somewhat surprised that such a large house was inhabited by only Saori.

"That's right."

Saori led her to the second floor, where she saw a spacious hall filled with numerous glass cabinets containing various figures, with robots being the most numerous, especially Gundam series figures.

So many—Black Cat was amazed. This tall girl was really super rich.

As for what Saori's family did, you could tell from the surname what kind of family business it was—truly an amazingly wealthy conglomerate.

It was hard to imagine that the young lady of such a family was a hardcore otaku.

"You can speak now, Black Cat."

Saori also sat properly with a very serious expression.

"Previously I chatted with you about my friend wanting to write a novel with the setting of the 'Interdimensional Channel'—most of that content was real."

"Mm."

"Then I confirmed that there are netizens who exist in works from our world, being main characters in them."

"Wh-what works!!!"

Saori instantly couldn't sit still and pressed forward to grab Black Cat, extremely excited.

"Is there Gundam?"

"Calm down."

"Ah, sorry, I got excited."

"One is Saeko Busujima from the recently published manga 'High School of the Dead.'"

Saori knew about this, which meant such a world really existed, and that world was really experiencing a zombie crisis?

"One is Miss A2, a character from the NieR game series."

"Ah? I haven't heard of it. No, wait, Black Cat, you mean this person should be from the third NieR series, right?"

Saori deduced this from the NieR game Black Cat had borrowed from her.

"Yes."

This made Saori really want to know immediately what the situation was, but she held back—clearly Black Cat wasn't finished.

"The next two are heavyweight."

Saori tensed up.

"Asuna and Magical Girl Madoka."

This statement made Saori's serious expression crack again.

"R-really? The female protagonist Asuna from Sword Art Online and Magical Girl Madoka?"

Saying this excitedly, Saori immediately walked to one of her figure cabinets containing all magical girl series figures, with Madoka series character figures taking up quite a bit of space.

They actually truly existed.

Suddenly thinking of something, Saori's face changed dramatically.

"Then, what's their situation?"

She couldn't help but get nervous, because these weren't fictional characters anymore but real existences.

"Asuna and Madoka joined just the day before yesterday, and Asuna happened to just get trapped in SAO. As for Madoka, she hasn't encountered Kyubey yet..."

Black Cat further explained some of Madoka's situation.

"Exploiting wish bugs? This requires competing in wisdom with a civilization—this is really..."

Incredible.

"Finally, the only male member in the group, who joined a few days before Asuna and Madoka."

This person was probably the main point.

Right, the only male!

This key phrase made Saori immediately realize who he was—the male protagonist in that somewhat Gothic-style future war footage.

"I don't know what work he's from. He's never revealed information, but he seems to know about all of us."

"Hmm? All? That means he also knows who you are, Black Cat? You're also a character from some work he's seen?"

Saying this, Saori's face suddenly changed again.

"Don't worry, Saori. He said the works we belong to are youth campus romantic comedy types."

Knowing why Saori's face had changed, Black Cat's words made her relax.

"And now..."

Black Cat further explained the cross-world invitation intelligence and energy coins.

She also said that with the videos she uploaded, the more people watched and the more popular they became, the more her energy bar could increase.

So if she continued uploading such works, without someone reliable to back her up, it would be troublesome.

Such quality videos would definitely attract many people wanting to recruit her for business cooperation or to spy on what filming techniques might have been used.

Then Black Cat would be in trouble.

If she had Saori, this seemingly super wealthy young lady, to help, she could update many series of interdimensional netizens' works.

Then she could help those interdimensional netizens who were currently in bad situations.

So she and Saori would be like forming a short video studio.

She would provide the videos, and Saori would handle operations.
