The patient Shizuka

"Dear, wait a moment."

Sona and Eiji had already come out of the bedroom and they had returned to the main student council room.

Tsubaki looked at her king's sweaty face and slightly disheveled hair.

She narrowed her eyes.

What had Sona and Eiji been doing in the bedroom for half an hour?

She didn't hear any strange noises, but she knew the two must have been doing something lewd.

Eiji who was about to return to class looked again at his fiancée and said: "What's wrong, Sona? Is there anything else you need to tell me?"

Sona didn't deny, she nodded and said: "Yes, I just wanted to tell you that in three days the underworld will hold its annual traditional event where all the young devils gather."

"That event is called the Youth Devil Gathering which all the old devils and the four Maou will also attend."

"So? You want me to be there too?" Eiji asked, after Sona mentioned the event, from the original work he knew what kind of event the "Youth Devil Gathering" was.

Sona nodded again, her hand slightly rubbing her throat before saying: "Un, that's right. Dear, can you? I'm sure Rias also wants the same thing."

Sona and Rias are both two devil heirs in the underworld, how could they not participate in the Youth Devil Gathering?

However, Eiji remembered that this was a special event for the devils in the underworld. What does this have to do with him?

"I don't mind attending that event. But isn't it a special event for you guys, the devils?"

For some reason Eiji winked at Tsubaki as he said that.

Tsubaki was confused. What did he mean? Did her King's fiancée just flirt with her?

"Un, that's not wrong. But Dear, have you forgotten who you are in the underworld?"

"Who?" Eiji tilted his head.

Sona rolled her eyes and said: "You're my fiancé and Rias. As your fiancé, you can also attend the event."

"Besides that. After what you did at the Peace Treaty conference before also made many people in the underworld want to meet you."

"So that's it...." Eiji was still smiling, but only Miss System knew the man was mentally groaning because it was troublesome!

"Dear, can you come along?" Sona hugged his arm and attached her bigger breasts from her original work flirtatiously.

Eiji nodded. "Okay, I will. Just let me know when the time comes."

Sona smiled at this, she stood on tiptoe and gave him a peck on the lips.

Tsubaki naturally turned her gaze in another direction.

She felt tormented having to keep watching such a couple scene in front of her eyes.

After Eiji completely left the student council office and it was only her and Sona.

Tsubaki looked at Sona and said: "Kaichou, what did I do wrong?"

"Huh? Tsubaki, what do you mean?" Sona was confused, she didn't understand what her Queen meant.

Tsubaki complained: "Aren't you punishing me? You made me stay here for more than half an hour just to wait for you to finish making out with your fiancé."

"You even made a single like me have to watch a scene of you kissing your fiancé in front of my eyes."

Sona widened her eyes, she did not expect Tsubaki to complain about this. Actually the reason she had the girl guard the student council main room was just to guard the entrance of the student council so that no one would enter carelessly while she was doing those things with Eiji.

She really did not consider that Tsubaki would feel sour waiting for her to deepen the relationship with her fiancée.

Sona felt a little guilty, she pretended to cough and said: "Tsubaki, I didn't mean it like that. Put aside what I just said to Eiji."

"But in the bedroom too we do important things. So Tsubaki, I really need you to guard outside so that our privacy is safe."

"Sona, I think you forgot I can also hear inner voices." Tsubaki said with flatly. When she and Sona were alone together, she would not be so formal.

"Ah!" Sona just remembered, she wasn't the only one who could hear inner voices. Her face turned red, but she quickly composed herself and said: "Alright, it's my fault. Tsubaki, how about we go to class now?"

Her king changed the subject, Tsubaki sighed, she nodded but did not forget to ask: "Okay, but why did you massage your throat several times? Does it hurt? What exactly did you just eat? You seemed to have eaten something while alone with Eiji-kun in the bedroom."

Tsubaki... Are you seriously asking that without being able to guess?

Sona blushed, actually her throat was a bit sore because for half an hour earlier she kept using her mouth to serve Eiji.

But Tsubaki was not an outsider, she was her servant and best friend, she honestly explained why her throat was a little sore.

Tsubaki who heard Sona's explanation blushed.

Her eyes gazed at the girl's small white neck and wondered how big and long the thing that had recently been inserted into it was that a devil as powerful as Sona felt her throat was a little sore?

It must be big...

Time flies.

In Eiji's basement where Lala had turned the room into a workshop where she made her advanced tools. The room was white as far as the eye could see with many designs and items that you could usually only see in Sci-fi movies.

All this alien technology was created by Lala, apparently when she wasn't in school and not spending her time watching anime. She would go down to the basement of his house, play in her workshop with Peke or other girls.

If not trying out some of her latest inventions, she'll be busy making other new ones.

At this moment, Eiji and Lala were standing in front of a giant computer-like monitor. No, it was actually the "Super-Duper Computer-Kun" that Lala had made which actually functioned the same as an ordinary computer, except that its specifications were hundreds of times higher than all super computers on earth.

This computer is also equipped with other advanced functions of course. One of them is to drive various production machines that can help Lala install bolts etc.

When Eiji first saw the basement of his house converted into an alien-level workshop+laboratory. He was naturally surprised, but when he thought of his pink-haired fiancée's abilities.

Eiji could only accept, and actually he also didn't mind Lala making the basement of his house like this.

Now the two of them were fiddling with some buttons on the computer. There was also a hologram displaying a device on the table.

Lala who was wearing a white coat like a scientist looked at the detailed data on the monitor and nodded.

"The progress level has reached 84%. Is this still not enough?"

The pink-haired beauty looked at her fiancé with an innocent gaze mixed with admiration.

Why? It was because she just found out Eiji was actually a scientist who was no less a genius than her!

Tonight, after dinner. The man discussed with her to make something.

A technology.

When she first heard what kind of technology her fiancé wanted to create, Lala frowned because it had to be said that it was quite difficult.

Even so, she would work hard to create the technology her fiancé wanted.

But...!

She didn't expect that her fiancé would also join in the manufacturing process. Lala was hesitant at first, but saw Eiji smoothly operating the "Super-Duper Computer-Kun" even though it was his first time using it.

And even did things that she herself couldn't do.

Lala was shocked!

"Not yet. This isn't enough." Eiji said, also wearing a white scientist's coat with his gaze fixed on the monitor. His own hands kept moving around pressing this and that very quickly and creating a new set of codes that were enough to blow up all the computers on earth.

Fortunately the "Super-Duper Computer-Kun" made by Lala was very strong and could withstand the operations performed by person with the understanding of the Mechanical Emperor.

"Eh, but Eiji. This should be enough to cover the entire earth." Lala said excitedly, she also just found out her fiancé liked to do crazy things.

Eiji glanced at his pink-haired fiancée, he smiled, pinched her cheek and said: "Who said I made it just to cover the whole earth? Lala, you might not know. On this planet, there are also other dimensions such as the underworld, heaven, and hell. There are also other dimensions that house gods."

"Unlike aliens who live on planets in this universe, people with supernatural abilities such as devils, angels, gods, etc have the ability to live in other dimensions in this universe."

"Fueee... So, you also want to cover all those dimensions with your technology?" Lala was a genius, she immediately guessed what Eiji's intentions were.

No wonder the man was still not satisfied with the amazing results he had achieved in 2 hours.

Lala's eyes lit up, but...

"Exactly. As expected of my first fiancé." Eiji patted the girl's head.

Lala smiled ridiculously. "Hehehe~ But Eiji, if this has to do with magic and supernatural beings like Rias, Sona, Akeno."

"I don't think science alone is enough to make the technology you want."

"We have to add magic elements to it."

Hearing his ridiculously smiling fiancée could still say that. Eiji knew what the girl said was true.

Science alone was not enough to develop this technology.

From the beginning he was also just trying his limits with the Mechanical Emperor's talent in handling technology.

It wasn't that the [Innate Machinery Soul] wasn't enough to create what he wanted, even Anos's creation magic had its limits to make the technology as complicated as he wanted.

The problem was that he and even Lala did not have the knowledge to combine science and magic.

Eiji himself had to at least see and touch a similar level of technology that combined both elements to know how to create it.

How about Sacred Gear? That thing also actually combines magic and science in it. The God of the Bible, apart from being extremely powerful, is also a genius.

But after checking, for example the Boosted Gear he looted from Issei. Eiji felt that the level of that thing was also not enough to make the technology he wanted.

After all, what he wanted to make no one in this universe had ever done.

In the end he could only learn to make it manually.

"You're right Lala. Well it looks like that's all for today. I wasn't in a hurry to make it either, and just did it for fun."

"It's already 9pm, let's go back upstairs."

Lala still seemed to want to continue their research in her workshop, but when he invited her to watch a movie together before going to bed.

She quickly hugged him like a koala and said "Okay~".

..

The next day.

It was Sunday.

Eiji remembered he had an appointment with a teacher.

Yes, a teacher.

[An unscrupulous female teacher who wanted her student to be her boyfriend.]

"Pretend! Eiji, you have to remember we're just pretending to date! Who's the immoral one?!"

Shizuka who had just come to the promised place originally wanted to greet Eiji who was standing beside the fountain. But she couldn't resist shouting at the boy hearing what he said in his heart.

She had dressed up very beautifully today. Her teacher's uniform that she used to wear at school had disappeared and was replaced with an elegant white crop top dress, tight black pants and white loafers.

With her black hair down, the woman was undoubtedly beautiful and more feminine than usual.

Although she still looked a bit tomboyish.

"Shizuka-sensei, what are you saying? At this time, you should have said 'Sorry for making you wait so long, Eiji' or you could have also said 'Dear, sorry I'm late. I've made you wait a long time. Instead, how about I give you a kiss?' something like that." Eiji shamelessly said with a gaze that noticed Shizuka's slim and sexy figure.

Shizuka who heard this took a breath. She tried to calm herself not to explode every time she heard what the boy said.

Not being able to say that she could hear his inner voice didn't help either but made her resist the urge to punch someone.

"How do I look?"

[You ignored my question and asked back? Shizuka, since when are you good at holding back your emotions from exploding? I'm a little disappointed...]

You bastard!

So did you intentionally want to make me angry?

Even so, Shizuka became even more determined to hold back her anger, she tried to keep smiling as she looked at her student's handsome face.

Eiji was also dressed up nicely today, with his silver hair slicked back, he wore a short-sleeved black shirt that showed off his golden figure as his muscles were a feast for Shizuka's eyes.

The boy's muscles were not as big as a bodybuilder, but lean muscles that were neither too big nor small enough to make the shirt he was wearing tight.

He was also wearing long cream pants with a black belt and black shoes. His shirt was also tucked into the pants, looking very neat and formal despite its simplicity.

Seen from anywhere, Eiji didn't look like a high school student at all in that outfit.

Now he looked like a mature man in his twenties who was handsome, tall and exuded the temperament of a rich man.

Damn! Shizuka swallowed, she had to admit that even though that boy was annoying, he had an appearance that perfectly suited her taste in finding a future husband.

Considering that she and the boy were only pretending to date to convince her mother, Shizuka felt a little comfortable.

It would be nice if such a handsome boy actually became her boyfriend and married her someday.

Um?

Shizuka gasped when she thought of this. What was she thinking?!

"You're very beautiful, Shizuka-sensei." Eiji said while looking at Shizuka who was inexplicably shaking her head while looking at him.

Shizuka who heard his praise was happy, but frowned at the last one and said: "You're handsome too. My mother will definitely be convinced just by looking at your appearance. By the way you should call me Shizuka. At least for today."

"Just Shizuka?

"Yes."

Eiji nodded and smiled before saying: "Alright Shizuka."

"...." Shizuka who heard Eiji say her name while smiling like that. Her heart pounding, she became somewhat dazed.

"Shizuka?"

"Cough! Y-Yes, now let's get into my car. Did you also bring a vehicle?" Shizuka who had a slight blush on her cheeks pretended to be calm and wondered if Eiji brought a vehicle to come to the city park where they met? If so, it was better to drive their own vehicles.

Although Eiji was a student, from his inner voice all this time, Shizuka knew that boy had a car and even a license to drive.

"No, I came here using teleportation magic from my home."

Eiji lied, he actually brought a car here, but he wouldn't mention it because he wanted to share a car with Shizuka.

As for his car in the parking lot? With his magic, he teleported the car back to his house.

Easy.

Shizuka believed what the boy said. As a young lady of the Hiratsuka Family who had been informed about the supernatural world, she naturally knew the existence of teleportation magic in this world as well.

She was actually a bit envious that Eiji could use such magic.

But put that aside.

"Then let's get in my car."

Shizuka held the boy's hand and pulled him along to her car. Eiji let her pull him along.

On the way, the two sat in the front seat with Shizuka holding the steering wheel.

While enjoying Shizuka's fragrant smell that wafted well in the car. Eiji often glanced at the woman sitting next to him instead of paying attention to the road.

Shizuka who felt Eiji's gaze felt embarrassed and said: "Can you stop staring at me? I'm driving!"

"What's wrong if I stare at a beautiful woman who is driving? Shizuka, are you embarrassed?"

"You! Do you want us to have an accident? Stop teasing me!" Shizuka complained, but she dared not glance at Eiji and focused on the road to hide her embarrassment.

Eiji chuckled at the sight of the usually shameless teacher at school being so shy just for being stared at while driving.

Shizuka's shy expression made him very excited, he couldn't wait to put the servant collar on her white neck and mark her. Not only that, he also wanted to see her wearing the dog collar while looking at him with an embarrassed expression.

That must be a good view!

Let's finish this quickly so I can claim my reward!

¶{Host, you are too excited. Please calm down and put the dog collar in your hand back into inventory immediately. Oh my... You'll scare Shizuka if she sees what you're holding right now.}

"...." Eiji hurriedly put the dog collar in his hand back into the system inventory.

Being overly excited, he took the thing out earlier.

Miss System was right, he had to calm down.
