It was time for both Tatsuya and Miyuki to enter First High school.

Due to the nature of the Yotsuba family, Rei decided to hide the fact that Tatsuya was his nephew for now.

"Remember, you'll have to call me sensei in school." Rei reminded as he jogged backward lightly while travelling with both Tatsuya and Miyuki.

"Understood uncle." Tatsuya nodded.

"No. What I mean is that unless we're at home, you have to call me sensei." Rei clarified.

"Alright sensei." Tatsuya said again as Rei nodded.

The entrance exam had changed over the years as Rei was the one to overlook the exam. He would choose those he deemed worthy to be in the demon class, and naturally he would include the friends Tatsuya made in the anime. Sadly, if he didn't do this, he wasn't sure if they would still be friends since Tatsuya could easily become a course one student.

'Let's see... In the demon class I have recruited Mitsui Honoka, Chiba Erica, Kitayama Shizuku, Leonhard Saijo, Shibata Mizuki and Yoshida Mikihiko. That should be all of Tatsuya's friends.' Rei thought as he looked at their student records.

'I should also give them bloodline sequences since they're Tatsuya's friends but not right now. I should do it before I leave.'

"Mitsui Honoka would fit the Loki System since her arsenal revolves around trickery. Chiba Erica would fit the Asura System as it benefits her swordsmanship. Kitayama Shizuku would fit the Quake System designed after the Quake Quake fruit due to the fact that her magic leans towards destruction and vibrations rather than accuracy. Leonhard Saijo would benefit from the Atlas System giving him supreme might. Shibata Mizuki would fit the Odin System due to her eyes. Yoshida Mikihiko would fit the Spirit Possession System that gives him the properties of the spirits he can control." Rei muttered making a mental note.

...

Fortunately, the first third of the year passed without much happening. Tatsuya made friends with everyone quickly and they were pretty close.

Blanche didn't attack either as Rei guessed it was due to him being here. On the other note, he did however, hear that Blanche attacked the Third High but failed miserably.

Walking into the cafeteria, Rei saw the eight of them hanging around once more. Keeping a light smile on his face, Rei walked over.

"Seems like the eight of you are quite close. It hasn't even been half a year yet." Rei said as they looked over.

"I can definitely say I'm close with the seven of them apart from one." Saijo said glaring at Erica.

"Hah?! You picking a fight?!!" Erica said as they stood up and glared at each other.

"Hahaha, from my point of view you guys look like an old married couple." Rei laughed as he pulled up a chair and sat down.

"No way!" They both shouted as the other six laughed slightly.

Rei was happy seeing that Tatsuya showing roughly 50% of his emotions now. The gates are slowly loosening over time.

"In a while the Nine School competition will be starting again. Tatsuya will be the main engineer to help you maintain your CAD's. It would be beneficial for you to sort it out sooner." Rei said gesturing at Tatsuya.

"Mn? Isn't demon sensei supposed to be looking after CAD's?" Saijo asked sitting.

"Who the hell are you calling demon sensei." Rei said turning over to Saijo who looked away.

"It's because u-sensei was a bit too outrageous in the previous competitions. Our school had access to the God Series, Sequence Coding and Visual Thought Conversion. Therefore, the Nine School Competition made a new rule which stops sensei from participating at all." Tatsuya explained with a smile.

'You were about to say uncle weren't you.' Rei thought turning to Tatsuya.

"Heh~ I didn't know that." Saijo said.

"It'll be weirder if you did know that dumbass." Erica said as they were about to fight again.

Rei smiled as he turned around. He could see the big three coming over.

"Mayumi, Mari and Katsuo. What's up." Rei smiled.

"Sensei." The three of them greeted.

"We were just curious since we heard something about Tatsuya kun being the main engineer." Mayumi said as Rei nodded.

"Oh don't worry about it. I taught him a few things as well not to mention he was pretty talented even without my teachings. Getting first place again shouldn't be hard." Rei replied as they all looked at Tatsuya in surprise.

"Eh?! How come I've never heard anything about this?!" Saijo exclaimed in surprise.

If was a known fact that Rei Yotsuba only taught classes and hardly any individuals. The only exception was Katsuo Yaiba and Ito Harumi who were engaged to each other.

"It's because I just never told anyone. Or else those old geezers would change the rules again." Rei shrugged as they looked at him.

'Aren't you a 48 year old geezer yourself? Who told you to look this young!' They all thought consecutively.

"Right now the rules stop me from participating. But it never stated someone trained by me can't participate." Rei continued as they thought and nodded.

The group including the big three and Rei chatted for a little longer before going separate ways.

###

"Everything is ready and now we just need a time to strike."

"How about the Nine Schools Competition?"

"I think that might be good. Since he is barred from the competition, he would be at the First High School. We can threaten him with everyone at the Nine Schools competition. If he refuses, then they could only be counted as a collateral." A person said grimly.

"Even if we have to destroy a large portion of Japan to kill him, it would still be beneficial in the future."

They all nodded.

###

Rei was leaning back on his chair bored as he watched the Nine Schools Competition.

This was his last year and so far the most boring.

Nothing happened, nothing went wrong. It was just him teaching constantly.

'Maybe you should go find some terrorists and kill them?' Lucifer suggested.

"I could. But I'd rather save it for Tatsuya since they were major events that helped him get closer to his friends." Rei replied.

'Then what do you suggest we do? You've almost reached Divine Rank 8 and then only two more ranks till Divine Rank 10. In this time, you should go skill hunting in other worlds. I know that there are a few good skills in Hunter X Hunter but that world's not available yet.' Lucifer said as Rei nodded.

"I think I'm going to bargain with the system god. Rather than imposing restrictions like this, he should just allow me to travel to other worlds quickly since I'm able to open up the portals myself." Rei said as he spun around on his chair.

'Why not annoy him.' Lucifer suggested.

"How and why."

'Repeatedly go to him saying - System God I've come to bargain. Do that a few million times and he should yield. As for why... because you're bored?' Lucifer said as Rei could picture him shrugging his shoulders.

"Perhaps. But I'm not saying that a few million times." Rei rejected.

Seeing the TV act up, Rei focused onto the TV.

-Everyone who is in the area for the Nine Schools Competition has been taken hostage-

'Ask and you shall receive.' Lucifer said as Rei could hear his smirk.

"This is different to the original attack but I'll take it." Rei smiled as he teleported.

###

"Everyone who is in the area for the Nine School Competition has been taken hostage! We currently have 50 Valkyrie satellites focused on this area."

The giant TV's had their views change as a silhouette appeared.

The citizens and students looked at the screens with confusion.

"Seen as though you don't understand the situation you're in, we deem that it is a requirement for us to demonstrate. This is the power of one Valkyrie satellite." The person said as the screens changed once more.

The screen displayed a satellite floating around in space as several segments started to open and expand. Magic sequences could be seen floating around the would be barrel as energy started to gather.

From a glance, Tatsuya could tell that the main source of energy was the sun.

*BOOOMMMMM!!!!!!

Faster than what they could recognise, the beam of energy shot down towards the empty field near the stadium. A giant scorched crater could be seen as the things that were nearby turned to ash.

Tatsuya had a frown as he realised he could barely formulate a shield in the time the attack struck using the Nano System.

"Miyuki, get everyone near me. I am making a dome right now to cover the entire venue." Tatsuya whispered as the edges were slowly being constructed around the stadium. Since it was far away from his body, the concentration it took was much higher.

Miyuki nodded as she quickly walked away.

"Our only goal is for Rei Yotsuba to surrender himself and his knowledge."

"Surrender myself? Interesting. The power of the Valkyrie was good but far from what can damage me." Rei muttered as he sat on the roof of the tallest building.

"We will give you five minutes! Rei Yotsuba, surrender yourself or the stadium will be wipe out. For every minute you don't appear a portion of this stadium will be erased. Once this is erased, we shall point the Valkyries to the entirety of japan!"

"Got you~" Rei muttered locking on the culprit's location through the information plane. No matter how much they try to mask their location, there will always be real records being stored in the information plane.

"We repeat! We will give you five minutes to a-"

"Hehehe no need. I'm already here." Rei's voiced rang out as they could see his silhouette behind the man.

"Wha-"

"Shhh~ Don't talk when I don't tell you to." Rei smiled breaking the man's jaw causing shock to the crowd.

"Now you see, here's the thing that all of you don't understand. When one understands the information plane like I do, there is virtually nothing I can't do in this world. Your Valkyrie systems? Gone." Rei said turning the screen to every Valkyrie system they sent out to space.

The Valkyrie systems collapsed on itself as they were compressed into a tiny ball of metal.

"See? Everything that is recorded in the information plane I can affect. And let me just let you know, E.V.E.R.Y thing is recorded. From the present to the past. I can change everything." Rei smiled as he turned the silhouettes off. They could see the man passed out from the pain and Rei smiling chillingly behind the man.

"I've tried to give you knowledge without fear. But it seems like my thoughts were wrong. I can see that being merciful was the wrong choice. Therefore, let me show you the consequences. As the man said. Seen as though you don't understand the situation you're in, I deem that it is a requirement for me to demonstrate." Rei smiled as they could see a densely packed ball of sequences materialising in Rei's hand.

"With my control over the information plane, I can make a separate world easily." Rei said as they realised a second moon was being formed.

"And at the same time, I can destroy anything just as easily." Rei continued as he destroyed the first moon.

"Since these were the first idiots to send themselves to me, I'll show you the harshest lesson. 'All who plotted against me and are connection with the current syndicate. Will be transported to Dimension 01, location- Arena." Rei smiled as millions of people disappeared in an instant.

"Everyone I would suggest you look away. It seems like my uncle will be killing a lot of people today." Tatsuya said as he turned to his classmate.

"Uncle?" Saijo asked as Tatsuya nodded.

"Now is not the time. I can tell you that my uncle won't spare any of them. Everyone who plotted against him will most likely die." Tatsuya continued as some of the weaker minded students nodded and turned away.

"Let's see~ Wow. Five million idiots plotted against me all at once. We have a few members from each of the ten families. And would you look at that. The elders of the Yotsuba family also appeared, every single one of them as well." Rei grinned as he floated above the arena.

"Let me show you what will happen to all of you in this dimension right now." Rei smiled as he gestured for one of the elders to appear beside him.

"Let me go! What are you doAAAAAHHHHHH!!!!" He suddenly screamed as they could see each of his bones break and ripe themselves out of his body. The bones became tiny bone spiders as they ate him from the inside out.

"I might have become soft in my methods over the years. Why don't all of you help me recover my edge and show the world why I'm called the demon?" Rei said as both his hands were drenched in blood.

For the next hour, the screens showed a massacre as Rei slaughtered everyone that had plotted against him. The world was given a cruel reminder as to what would happen if a person gained this much power. They could be merciful and try to teach like what Rei tried to do initially. Or they could become the very thing that has the potential to end the world.

###

"Hais.... I guess he really wasn't suited to try sort everything out peacefully." The system god said as he watched the slaughter.

"Hehehe, I told you. He is fit to be a war god. Not to mention the slaughter god and demon god had already deemed him their successor as well. Why try stop the inevitable?" The war god chuckled.

"Because constant slaughter is bad mentally." System god shook his head.

"Well I wouldn't say constant slaughter. The boy did try to solve this world peacefully but seems like they didn't appreciate him and thought he was a paper tiger." The beast god smiled looking at the slaughter.

"You're too naive system god. They were the idiots to not recognise the danger. I'm pretty sure Rei told them that he controlled the information realm in their world. Which basically meant the world since what ever happened in one would affect the other." Ophelia said as the system god nodded. He really couldn't blame Rei since the humans in that world were like a child. Give them some leniency then they'll see how far they could take that. Unless you teach them a harsh lesson on consequences, they would continue to push your patience.

"Esteemed gods! The war has started!" A person suddenly shouted as he burst into the room.

All five gods stood up in tandem baring serious faces.

They nodded at each other before rushing off.
