"The Fourth dimension, is something you can't actually get into, firstly." Kanazuma said.
"The same as it is theorized on earth, human brains cannot comprehend the fourth dimension. One of the ways it was described is a tesseract; a cube within a cube.. That's something that is quite....Challenging to comprehend. Or basically, another thing... We are three dimensional beings, and we cast a two dimensional shadow. For Fourth dimensional beings, they cast three dimensional shadows. Try to envision that; a three dimensional shadow." He said.
"True, that sounds like it can't even work.."
"So one thing is, you actually can't tap into the fourth dimension as you are, you are human after all, but I shall just teach you how it works, and how you can tap into the fourth dimension."
"The fourth dimension, a place supposed to have beings that we cannot comprehend, beings that can just make us die by looking at us... I wonder it actually looks." Mitsuki thought as he continued listening.
"The fourth dimension has its beings, might you know them?"
Recalling the talk Mitsuki had with the strange entity, Mitsuki nodded.
"There are the Regulators: Fourth dimensional beings that are said to be living horrors, then there are the Superiors: Time, Reality and Order, Space, Energy and The Great Encoder." Mitsuki said.
"T- that's impressive, I never expected you to know them. But now that you know them, let's continue."

Avalon
Aurendor looked at all the frozen gods, wondering why Kanazuma had requested him to do so.
"If it is to train Mitsuki in any sort of way, then that's okay." He thought. Just then, the divine spirit appeared in front of him.
"What is it?" He asked. If the divine spirit had broken out of time to speak with him, then it was something urgent.
"It is I, Herald"
Aurendor immediately composed himself, giving a slight bow to the being speaking through the divine spirit's mouth.
"This is about Venus.. Have you heard from him?"
"Unfortunately, no I haven't. Is there an issue?"
"That Venus... He has not sent any word to us at all for a celestial half year now. We also cannot find his realm anywhere...."
"He is giving us quite the stress," Aurendor remarked.
"Regardless, your Ichiro boy has stirred up quite the trouble, you know that?"
Aurendor looked down, thinking back at the terrifying prescence he ad felt back then which was enough to even gain the attention of the beings such as the one talking to him right now.
"Speaking of him, where is he right now? I am quite interested in him."
Aurendor sighed as he specified where he was.
"And what do you intend to do to him?"
"Nothing, I am just going to look at him up close," Herald said as the space around him started glitching.
"Look at him? I know this guy will do more than that!" Aurendor thought.
"Thanks for the info, now I shall take my leave." Herald said.
*******
"Have you understood all of that?" Kanazuma asked as he finished explaining. The whole place was filled with equations and symbols written using mana. Mitsuki's head was steaming, as he tried to ingest all the information that had been poured in him.
"Nope, I haven't." He replied, his eyes blank.
"What!? How? You want to tell me that I have talked for I don't know how long, yet you haven't understood a thing?"
"I have, but I can't just understand all the quanum physics and energy control dynamics you just said right now, I'll need time to break them down." Mitsuki said.
"Fine then, we have all the time here," Kanazuma said, sighing.
"He just sighed.. Am I that stupid...." Mitsuki thought as he pouted.
"Relax, I'm not sighing because I'm tired of you or something related to you and understanding, I was just contemplating something.." Kanazuma said, patting Mitsuki's head.
"I'll leave you for a bit, so that you can absorb all of this, just let me tell you this to motivate you,"
"What?"
"There is someone who can fully enter the Fourth Dimension, a boy who is turning 18 soon,"
"Wait what?! Do I know him? What's his name?"
But by the time he was asking this, Kanazuma had vanished.
"You'll know soon enough," Kanazuma's voice echoed in the timeless expanse.
Suddenly, Mitsuki coughed out blood. He sat down in a lotus position.
"I just noticed... Talking here consumes mana... Figures.. Time has stopped, so waves are also frozen in time... You need to focus mana on your voice box and you also need to control it to convey your thoughts... " He thought as he looked up at the equations floating in the mass expanse.
"How the hell does he want me to understand the McGucken Equation and Schrodinger's equation!!! And what the hell does he mean by saying the fourth dimension is time and yet there are still entities of reality and order there!!!!" He shouted in rage, causing him to cough out even more blood.
Kanazuma observed Mitsuki trying to compile all the things he had learned with a smile on his face.
"Don't worry Mitsuki, I said all that science because I know you can learn how to actually apply them into mana. I have raised you as my own back on earth and I have seen how quick you are to apply the knowledge that you gain into practical use.. I believe you can actually surprise us quite well," he thought as he decided to leave.
Mitsuki closed his eyes, meditating until he found himself in a colorful world, a world full of several colors; the mana field essence realm. A world that Kanazuma had told him about.
"It's true.. I can feel it.. The rich amount of mana that is in here.." He thought as he remembered Kanazuma's words:
"Absorb it steadily, until you reach your limit, over and over again. That way, you will be able to expand your vassal energy... By doing so continuously, you will force your soul to transcend.. Even though I can't know the path your transcendence will take, all in all, you will be able to access the fourth dimension."
"Let's see... Control the pure mana ..."
Cloud like matter started swirling around him.
"Yes! I'm doing it!"
Immediately he lost focus, the clouds suddenly went wild, causing them to burst out as spikes. Mitsuki opened his mouth to scream, but no sound came out. He fell down on the ground as he tried to heal himself. He gasped for air as he placed his hands on his chest. His mind was in a state of panic as his instincts wanted to take over him, to make him run away from such a painful experience. He threw up blood, a lot of it. Because of this, he fully lost his concentration, forcing him to fade out of the mana field.
"What the hell man... Why didn't he say something about this..."
His vision was getting blurry and his thoughts were all over the place.
"Crap.. I am going to pass out... Breathe Mitsuki, breathe.... Compose yourself." He muttered to himself as he lay down flat on the ground. He looked up at the equations as he tried to prevent himself from passing out.
"Let's see... Equations... How should this hel-"
Suddenly, an idea struck his mind.
"Encode..... Maybe it can work!" He thought. Now psyched up, he tried rubbing his eyes, hoping that the blur will clear out, but he felt a warm liquid adhere to his fingers.
"What is this... Its red.. Blood..."
His body or rather, his soul was in a lot of pain, following the spikes penetrating not only through his physical body, but also through his soul. He just slumped back onto the ground and looked up and tried to ignore the pain.
"Encode.."
His hand got covered by a weak red aura, causing numerical symbols to appear in flashes and glitches. around him.
"Let me try this then, even though it might cause me to be in more pain..."
Suddenly, what appeared to be glass shattered all around his body, dissolving into a neon green fluid which then seemed to float on air as small droplets. His system notification suddenly appeared as his body felt lighter. The red crown appeared on his head, but this time he had no wings, and his eyes were not red.
"This crown... What am I, some random King?" He teased himself.
[Orchestra of Chaos form is active]
[Beta]
"I can delete the effect, so now it is as if I am not frozen in time.. Now, l can check the encodi- Wait a second..." He said as he tried to rise up, a futile effort."
"He said.. That time has been frozen right now all over the universe... So, where the hell am I? He said as he smiled while looking at the equations floating in the air. Following their principals, it was as if he was there, but not truly there, all at the same time. He tried releasing all his aura, but it was futile. A smile grew on his face as he sighed.
"I made it.. I can now tap into the fourth dimension! While I am still huma- oh wait, while I am in this form..." He said as he felt proud of his small achievement.
Herald watched him from the fourth dimension.
"If only things were that smooth, boy." Herald muttered to himself.
"In that form, you definitely use such parallel methods to tap into the fourth dimension, but....."
"There are orders and rules to be followed or else....."
As Mitsuki was there happy about his achievement, he suddenly found himself back in the mana field essence realm, but this time, it was all cloudy.
"WHAT-"
As if led by a common purpose, all the cloud matter solidified into dense mana simultaneously, in a speed that Mitsuki could not even comprehend, then...
Like flowers of the Night-blooming Cereus, they all bloomed into large sharp spikes, with Mitsuki at the center of it all, painting the already colorful realm red masterfully, using Mitsuki's blood as the paint.
