This has hints at masturbation and erotic material, but never specifically describes it (or it probably won't).
This takes the perspective of Peroronchino; the creator of Shalltear.

PLEASE tell me if this should be considered "M", because though I don't think these subject matters are that uncommon for any teen who has been exposed to the internet, that is only my opinion. That is why I set it to "T", though viewer discretion is advised regardless.

Pure Pure Pleiades

Part 1

Peroronchino took a deep breath; his eyes slid shut and his pulse calmed to a slow beat.

"Log out," Peroronchino commanded.

His consciousness flickered for a moment, a disorienting experience for any who had never felt it before. It was akin to seasickness, to the brief moment of weightlessness when falling, when one's sense of balance and self-control were all but specs of dust in the afternoon breeze. To Peroronchino, this was a regular occurrence. In fact, it happened just about every day, whenever he logged out of YGGDRASIL. Some might call it a bad habit, others an obsession, but as a healthy teenager, Peroronchino, or Ohno Shota, wasn't abnormal by any means.

In fact, aside from having a large collection of hidden eroge, dating sims (galge), visual novels, and an obnoxious amount of time spent in YGGDRASIL, Shota could truthfully boast being a fairly average member of society. He, a high schooler, had good grades, attended an above-average school, and – if he dared say it – good looks. Though Shota was relatively thin, he spent almost all of his free time in games, and consistently managed to hit YGGDRASIL's weekly time cap.

Still, to the world beyond his sister and friends in YGGDRASIL, Shota was a hard working studious teenager who had strong work habits. Shota didn't study at home; his policy was to work as hard as possible so that he would have as little as possible to do at the end of the day. Since Shota lived with his sister, his parents knew nothing of his game obsession. Even his sister didn't know some of the darker things, because of course; Shota wouldn't ever show her his H-games. It just wasn't something any "normal" seventeen year-old would want to talk about with his older sister.

His older sister was a tyrant, after all. Shota could only watch in horror at the strict sanctions she posed; the only reason he was allowed to game away his nights was because she was there to regulate him. It was as if she wanted Shota to listen to her! Ridiculous. Respect should be given to those who deserve it, not automatically to one's elders.

Cultural revolution! Change this unfair set of societal expectations! Band together and revolt against the old standards!

Er, maybe not to that extent, China's cultural revolution from the 20th century would be a bit terrifying in Japan. Even worse, the wonderful culture of eroge and galge might be damaged in that struggle of identity.

What was more fearful was his sister's ability to alter her voice; she could, in the sweetest sounding tone, threaten to kill him. Shota supposed that it was worth it; she had gotten employed as a voice actor a few months back, and that income fuelled better food. It was at a famous studio too, Maeda Entertainment, though Shota didn't know what they saw in her. Sure his sister's voice could be cute, but the fact that it was his sister ruined everything.

That may have been the catalyst for change, the start towards that terrifying day of reckoning.

…

"Shota, I'm going to the gym," his sister announced. "I'll be back in three hours."

Shota glanced to his sister who stood by the door, plump with well-rounded sides. If Shota was thin, then his sister was fat. There really wasn't any beating around the bush; her waist measurements were higher than the Japanese regulations, and could be considered overweight. She even had to pay the extra tax for it. Granted, she was… somewhat thinner than before?

"You're going to the gym? Since when did you care?"

His sister narrowed her eyes, and Shota instinctively looked down to his food. He felt a glare that could kill on the back of his head, but pretended he didn't notice.

"Since I got a job," His sister said. "Got a problem with that?"

"Nope, have fun sweating."

With that, his sister was gone. Shota was home alone, and that meant one of several things. He could, if he felt so inclined, take out some of his… adult material, and do some exercise of his own. Or Shota could get an early start on grinding mats in YGGDRASIL; the newly created guild home was pretty demanding.

Shota chose the third option; he decided there was no better time than the present to snoop through his sister's room.

"I wonder if she's gotten anything adult rated," Shota muttered as he searched.

His sister was neat and organized: papers and scripts were neatly piled on the table, the tablet was turned off and left in the desk, with the wall screens in a similar state to save power. Her bed, though a female slept there, provided no tension for Shota, who knew that its tidy sheets belonged to his older sister. The closet was as usual, with a few outfits here and there, an unidentifiable white box…

Wait, just a moment.

An unidentifiable white box?

Could it be?

A secret?

It certainly hadn't been there the last time Shota had gone through his sister's things.

"Let's just see here…"

Shota lifted the box, with a single marking indicating a sender, and deposited it on the bed. Its sender was Maeda Entertainment, the company his sister had worked with. A bead of sweat began to make its way down Shota's face. Maeda Entertainment was one of the most famous studios for eroge, galge, and other amazing content. They were pioneers in their field, and dated back to the early 2020's, with outstanding content for the past century.

Of course, Maeda's games were a personal favourite of Shota. He had a huge number of their titles in their fancy limited-edition promotional arts, some hidden inside the frame of his bed, others proudly displayed for the world of his room to see. There was a game release next month, a highly acclaimed title called Pure Pure Pleiades!. A wonderful tale of love, friendship, and possibly erotica with a huge variety of girls! Shota couldn't wait… but it was a title from his sister's company.

For reasons Shota couldn't understand, his sister had banned him from pre-ordering the game; she pointed at the overwhelmingly high price, but Shota had no qualms. If he needed to, he could easily make that amount of money from a month or two's savings as a part-timer, but he needed his sister's password to order it.

Had his sister received a copy before release as a gift? A thanks for her work, on whatever smaller, less-important title they had employed her for? Maybe all employees got one… the very thought made Shota want to check how to get into the industry. Of course! He had a connection! His sister already worked at Maeda, and could recommend him if he asked. Excellent start!

Except his sister wouldn't want him to pursue that kind of career. She would want him to get a "stable", "normal", "well-paying" job. Like a doctor or something; games were as far removed from saving lives as apples were from potatoes and pineapples. Shut down at the gate and locked out of haven, Shota almost felt a tear come to eye. That route was definitely a no-go.

But that was enough stalling!

Shota slowly unclasped the parcel, and lifted the lid. No, it couldn't be. But it was.

Pure Pure Pleiades! lay before him; an auto-chip nestled in its case. The scenario was almost suspiciously perfect, the case clean and completely untouched. If Shota sold this, he would make a fortune by selling the game before it even released.

No, there was a better choice, one that would preserve his fertility and the safety of his reproductive organs from a certain sister's foot. Shota would play the game, but only when his sister was out. Since she had just committed to exercise, she would be out daily. Shota could also sneak it out at night; he only needed the chip inside the box within the packaging, and his sister was a heavy sleeper. With any luck, she wouldn't notice the chip was gone from the casing.

Shota carefully extracted the game, slowly, ever so slowly. A single scratch could ruin the casing, and that gorgeous art begged Shota not to. He turned it over, eager to dismantle it to retrieve the prize, when he realized. There were signatures. All over the backside, signatures of names Shota recognized. The director, the animators, the voice actors… this was priceless.

Shota silently thanked his sister. With the auto-chip in range, Shota could access the game, that oh-so-wonderful game. Really, there was no reason to take the chip out, right? Shota's sister would be out for at least another two and a half more hours, which was plenty of time. The heroines of the story seemed to agree, their expressions full of joy on the art. Even the cool, level-headed love interest seemed to smile, ever so slightly.

"Don't mind if I do," Shota said to himself.

With the chip still in its case and fully secured, Shota ran to his room, to boot up his computer. He could not spend another moment without the game; it had been on the very top of his most anticipated titles list for a full year. His system picked up on the signal, and Shota was in. Of course, Shota needed to use his headset, not his dive gear, because erotic virtual reality games were banned. That was no problem; this gave him full control of his right arm and lower body, which was just as good.

And it was glorious. The H-version's uncensored intro animation alone was enough to get Shota stiff. All the love interests, as expected of Maeda Entertainment, were alluring in their own right. Whether it was the Goth Lolita or bouncy Onee-san, each and every character charmed Shota. It would be hard to narrow them down to a single initial target. In fact, even from the beginning of the game, it might be better to proceed… without the pants on?

Shota pulled off the headset, and quickly rectified this issue. He made sure to set a few timed warnings, to prevent the horrible death that awaited him if his sister found out. Shota did, after all, need the time to wash up before his sister came back.

"Perfect."

Ohno (sometimes written Ono) is a semi-common last name in Japan, and Shota is a fairly common first name. Thus, Ohno Shota was created.

Hm... I think this will be done in one more chapter? Maybe two, if I somehow come up with more content to stuff in, though I highly doubt it.

I swear, it'll probably get somewhat amusing/comedic by the end. Probably.
