Chapter 52 ~ A Productive Day

A few days have passed since the Nine Schools Competition ended.

With Tatsuya eliminating all Japan branch board members of the No Head Dragon, they've finally completed all but one last mission from the Multiverse Group Chat; defend Yokohama from the foreign invaders.

So for the last few days, Yuuji, Aika, and Tatsuya had been enjoying their "time off" and relaxed, winding down from the "eventful" last few weeks.

Tonight, Yuuji spent his evening in the lab with his computer to work on the stock market analytics he wanted to give to his mother after he finished his daily trading routine.

His mother was an accomplished trader and a genius investor. In truth, she wouldn't need anything more than her current stock market analytics software to make proper decisions and gain profit. But Yuuji still wished to make it.

If the one he made could alleviate at least a bit of her worries and stress, and make her work smoother, then he would complete it no matter what. With this, he hoped he could give her more time to have for herself and not worry about their family's financial situation.

But as he continued to develop it, problems that made his fear became clearer and clearer began surfacing.

Creating a 100% accurate stock market computing software was equivalent to trying to gain the ability to look into the future. There are simply too many unpredictable variables in this world to be able to predict the trend of a company's growth or decline with 100% accuracy.

The best stock market analytics algorithm in this world had an overall accuracy of around 80%. In Yuuji's world, this number was even lower. So an accuracy of 90%, which was Yuuji's goal, was almost impossible to achieve.

At least, without the required technology and computation power.

"As expected… There's no other choice but to buy the MCGX SuperComputer, huh?"

The MCGX Supercomputer was a portable, advanced quantum supercomputer with the processing speed of 10 million TFLOPS, which is more than 10 times faster than the supercomputers in his home, and several times faster than even the best supercomputer in Tatusya's world. Moreover, it could also transfer and receive data from across universes, just like his phone.

With this, he would certainly be able to create the greatest stock market analyst program with more than 90% accuracy.

The only problem he had with it was its price.

The supercomputer alone would cost him 3500 GCP, and if he wanted to have a Data Center for reliable, fast, and secure storage hardware, it would cost him an additional 3000 GCP for the MCGX Data Center.

If he were to use it for a stock market analytics program alone, it would be way overkill and also too expensive.

"No… Maybe it's worth it…"

Yuuji didn't stop at just creating a stock market analysts program. He wanted to develop a program that would allow him to communicate with people from other worlds who weren't in the multiverse chat group.

Although it would be impossible to talk with his family while he's on a mission, since time would stop in his world, he wanted to be able to talk to them while he was visiting other worlds.

Moreover, from this mission, he had learned that there was an extremely high chance of him developing feelings for more than one girl… And since they could only invite one person to the MCG, Yuuji wanted to create a way for him to communicate with them even after he returned to his original world.

Making the application itself was easy, but he would need to be able to transfer data across universes. And the MCGX Supercomputer was capable of doing it.

Perhaps, he might even be able to create a virtual network that would link his family and friends' phones from across the universes through this, allowing not only him, but all of them to talk with each other anytime they wish.

"Aaaaaah… I guess the next project is decided."

He stretched his arms and body, releasing the tension that had been accumulating in his muscles from the hours he had spent sitting down and working on the analytics. Well, at least in his mind.

His [Divine Physique] wouldn't accumulate any fatigue from doing such activities. He could do it for years without moving, and his body would not have suffered from any muscle pain. He only did it because his mind hadn't fully comprehended the extent of his divine physique's full potential.

"Alright… Let's begin planning for that virtual network tomorrow. I might be able to call Tatsuya for that too and ask for his opinion. But for now…"

Yuuji opened up a new tab from his browser and began searching for online courses to learn German.

He had delayed learning it for too long because of everything that had happened with the events and incidents happening in his school and his private life. But he still wanted to learn it so that he could speak with the daughter of his mother's friend and make her feel welcomed and comfortable.

Mira said that she could speak English fluently and had started learning Japanese. So in truth, there was no need for him to even bother learning how to speak German since he could already speak English fluently.

But she was a young girl who came to live in a foreign country alone… Even though she could speak English and a bit of Japanese, she'd definitely feel more comfortable if there's at least one person who could speak to her in her mother tongue.

And since he could learn things extremely quickly, there was no reason for him not to. There's no drawbacks in learning a new language, and if he could make the daughter of his mother's close friend feel more welcomed and comfortable to be in Japan, he'd do it.

It was simple enough to find both free and paid online courses for learning German. So first, he learned from the free online courses first before he started buying the intermediate and advanced online courses

And after two hours, he had already completed the intermediate courses. At this point, he was already extremely fluent in conversational German. The advanced course would elevate his level from being conversational to business level fluency.

But before he could continue, the door to his lab slid open and a familiar, super soft, and warm body hugged him from behind.

"Yuuji~ What'cha doin'~? Ah, mmnnchu~"

Aika excitedly wrapped her arms around his neck, pressing her prided, enormous breasts onto his back. And like the kissing maniac she was, she peppered the side of his face with a lot of kisses.

And to her loving greeting, Yuuji responded back by taking her lips into a sweet, loving kiss.

"I was learning German after I finished my programming stuff."

"Eh? German? But why? Are you planning to go there?"

Yuuji shook his head.

"I'm not. I'm learning it because the daughter of my mother's close friend is transferring into our school. She could only speak English and had just started learning Japanese, so I decided to learn her mother tongue so she has at least one person she could talk to in her native language."

Aika's eyes immediately sparkled and her lips curled into a grin. And with one swift movement, she turned Yuuji's seat around and sat on his lap sideways and whispered directly into his ear.

"Is she cute~?"

Yuuji thought for a moment, before shaking his head once again.

"I'm not sure. I've never seen her before, so I can't say."

"Hm~ Well, if she's cute, then capture her too~ I would love to taste a cute, blonde-haired German girl~"

Yuuji smiled helplessly and pecked her lips before he began stroking her hair.

"Let's just see, okay? You know I don't like forcing anyone to fall for me, right?"

"Mm, I know~ But you better chase after her if she showed even a slight interest in you okay?"

"...If I share the same feeling, then okay."

"Great~!"

Aika giggled and tightened her hug around his neck as she enjoyed being cradled by her beloved.

Just then, the sound of the automatic metal door whirred open. Yuuji and Aika turned towards the sound, and saw Erika walking in, wearing a light blue tank top and hot pants.

The moment she saw them, Erika smiled helplessly and let out a sigh.

"Hah… I should've known Aika would immediately flirt instead of asking the question."

"Hm? A question?"

"Ah! I forgot!!!"

"...How can you forget?"

"What are you talking about?"

Yuuji looked at the two back and forth confusedly before getting his answer from Erika.

"She came here to ask if you'd want to go out and eat dinner outside tomorrow."

"Oh? Of course. Do you have anywhere in mind?"

"Uhn~! There's this new tonkatsu restaurant just a train station away from here! We can go there for dinner and then walk around for a little date, just the three of us~"

"Oh, that sounds interesting. Sure. I'd love that."

"Alright~! It's decided then~ I'll go ahead and reserve a table for us now~! Oh, and are you done with what you're doing?"

"Hm…"

Yuuji turned his eyes towards the clock on the bottom left corner of his monitor that showed 21:09.

"I'll be here for maybe another 30 minutes to an hour. I want to finish this course today."

"Alright~ Then we'll be in your bed, ready for some cuddles~"

"Hm? What course are you doing, Yuuji?"

Erika asked, peering over to his computer curiously.

"Fufufu~ He's learning German to woo over a german girl~"

"Eh?"

Yuuji knocked Aika's head for saying such misleading things.

"Stop causing misunderstandings."

"Tehe~"

He sighed and turned towards Erika to explain the situation.

"Oh, I see. That's nice of you."

"Fufu~ It really is~ I'm sure she'll definitely fall for you~"

"Hah… That's not why I'm doing this…"

Yuuji shook his head tiredly as Erika laughed helplessly.

Since becoming Yuuji's lover, Erika had gotten used to sharing him with Aika. Everything she feared when she thought about having to share the man she loved with another girl never happened in reality.

She got plenty of attention from Yuuji, and he also spent a lot of time with her and Aika as well. He never neglected either one of them and did his best to make both of them feel very loved.

In fact, being in a relationship with him made her closer to Aika as well. They shared everything with each other. Their feelings. Their thoughts. Their secrets. Even their sexual kinks and fetishes… Though the last one was forced out of her by Aika.

But for the first time in her life, Erika felt like she had gotten an extremely close friend, or even a "sister". Someone she could trust and share her feelings with. And along with Yuuji, she finally felt like she had found a new family to be with for the rest of her life.

"Alright~! Erika, let's return to our room first and watch some anime while we wait for him~"

"A-Ah, Aika stop pulling me! Damn, you're so freaking strong! Stop! I'm going, okay?!"

--------------------------------X--------------------------------

The night after.

As promised, Yuuji brought Aika and Erika over to the newly established tonkatsu restaurant named Maruyama Kibbei Tonkatsu near the train station.

Despite its recent opening, there was already quite the massive line in front of the establishment. Fortunately, Aika had reserved a table for them, so they didn't need to wait in line.

As soon as they entered, all eyes turned to them in an instant, especially Yuuji and Aika. Although it was the usual and they had gotten used to being stared at, being in such a crowded place made the stares even more conspicuous.

I feel like I'm in my school's cafeteria all over again…

The feeling of being the center of attention in a public place like this still made him a bit uncomfortable. But he quickly refocused his attention on protecting Erika and Aika from the guys, who were clearly staring at them with obvious lust and interest.

The three were led to their table by a beautiful, young waitress, who was conducting herself very professionally. At least… if they ignored her clearly blushing cheeks and the glances she stole towards Yuuji.

Once they were seated, Aika looked through the menu for a few moments and quickly ordered the most expensive meal set… The Special Premium Tonkatsu Set.

"Oi… Aika. Are you sure…?"

Yuuji looked at her worriedly. Even Erika and the waitress were shocked at her order.

The Special Premium Tonkatsu Set was the most expensive meal set in the entire menu. It cost 8600 yen, but that wasn't why Yuuji was worried.

The meal set consisted of a large tonkatsu, a mountain of sliced cabbage, a bowl of rice and miso soup, a tempura set, and a pork shabu-shabu for two people. It was a ton of food!

Even though Aika's metabolism is through the roof, it would still be difficult for her to finish this much food!

"Hehehe~ It'll be fine~ If I can't finish it, then you can eat it~"

Aika waved at Yuuji dismissively and winked to Erika.

"Erika, you should order anything you want~ This guy's stomach is as bottomless as his pocket, so don't hesitate~!"

"Oi…!"

Yuuji narrowed his eyes on his cheeky girlfriend. How could she say such a thing? She made it sound like he's her gluttonous sugar daddy!

"A-Aah… I'm fine… I'll order the normal tonkatsu set, please."

"I'll order a normal tonkatsu set as well. We'll have plenty of food either way from Aika's meal set."

"I-I understand. How about your drinks?"

"I'll have an iced green tea."

"I'll have an iced lemon tea."

"Iced orange juice for me please~"

"Yes, I understand. Then, please await your order."

The waitress bowed and quickly made her way back to deliver the order to the kitchen.

Half an hour later, their orders began arriving to their table. The first two were Yuuji and Erika's order, the normal Tonkatsu set which consisted of a bowl of rice and miso soup, and a large tonkatsu with sliced cabbage on the side. And after that… Aika's order began coming in.

The waitress who came to deliver their order had to call on the help of another waiter to help her carry it. One by one, she began placing Aika's order, and by the end of it, her order took up half of the table herself.

Even the people around them, who were staring at them before, were now staring at her order instead! It was their first time seeing the Special Premium Tonkatsu Set in person… After all, it was 8600 yen, and it was their first time here! They didn't want to risk paying such a price before knowing if it is good or not.

"Mmm~! It smells so delicious~ Then, thank you for the food~!!!"

"Hah… Thank you for the food."

"A-Ahh… Thank you for the food."

Aika began digging into her feast while Yuuji and Erika also began to eat their meal.

And as they all expected, Aika was full after just finishing half of her food, and she had Yuuji eat the rest.

"Haaah~ That was so nice~ Hey, Yuuji. Hurry up and finish your food~ We still need to go window shopping~"

"..."

You cheeky… Just watch, I'll punish you in bed tonight…

He grumbled inwardly.

After finishing their meals, Yuuji paid with his card and the three exited the restaurant to go walk around in a popular shopping street near them.

"Yuuji! Come here! Look at this! Isn't this cool~?!"

"Erika, look at this! Why don't you try it out! I'm sure it'll look good on you~!"

"Yuuji!"

"Erika!"

"Yuuji!"

"Erika!"

…

After going around for a while, Yuuji finally got a bit of rest while Aika and Erika went to try out some clothes from a boutique Aika was interested in.

He waited in front of the changing room. His figure attracted a lot of attention from the women and female staff members in the store, but he ignored them and just took a second to rest after the whirlwind "shopping" Aika had dragged him and Erika into.

Just then, his smart phone rang.

He took it out from his pocket and looked at the screen. It showed Tatsuya as the caller.

"Hm? Tatsuya?"

Yuuji had planned on talking to Tatsuya to discuss his plan to create the virtual network for his pseudo multiverse chat group app after the date tonight. But he didn't expect Tatsuya to call him instead.

"Hey, Tatsuya. What's wrong?"

"Yuuji, will you be busy tomorrow?"

"Tomorrow? No, I don't think so…"

"Then, can I ask you for a favor?"

"Of course. What can I do for you?"

"I'd like your help in researching a way to store Magic Sequences, specifically on the Magatama… I'm sure you know what this is."

"Yeah… I do."

In the Mahouka Koukou no Rettousei anime, "Holy Relics" were "out-of-place" artifacts that contained magical nature that had unidentifiable artificial components, yet formed naturally under highly challenging conditions. And the Magatama was a type of relic which had the ability to store magic sequences.

With it, machines that could store magic sequences and only needed to be activated by a magician once and keep working could be created. This was an extremely valuable and sought after trait.

Tatsuya wanted to research this relic so he could find a way to store magic sequences in an object and create an energy resource that could function with just an initial jumpstart from a magician without the need of one to keep it working.

With flying-magic now realized, sustainable nuclear fusion through Gravity Controlled Magic was well within sights. But to keep it working, a magician still has to keep casting spells throughout it all. In that case, the magician is no more than a component of the nuclear fusion reactor.

They would only be changing roles from a weapon to a component. That is why, there was a need to find a way to store magic sequences.

"Alright. Where do you want to meet up?"

"Meet me in the library."

"Sure thing. Then, I'll see you tomorrow."

"Likewise. Good night."

Yuuji hung up, returned his smartphone back to his pocket, and continued to wait on Aika and Erika.

And only after a few moments did he realize…

Magatama… Research… Wait… Isn't this the start of the next arc?
