As someone who's been training his body for a couple months now, he surprisingly, didn't know the basics?

What in the world was aura?

"As you all know, utilizing our aura, we can use battle techniques that further strengthens our physiques, not only that, but it can also improve our five senses." Aster smilingly continued, looking at every student the same way.

Looking back towards the holographic screen, he swiped, showing a completely new view, which he explained.

With a body that was highly detailed, showing almost every artery, which was filled with an odd, yet extremely pure dark blue mana.

"As aura empowers our very bodies, it doesn't strengthen just the outer shell, but even our organs themselves." Aster looked around, and seeing no confusion or raised hands, he continued.

"Nonetheless, with techniques that reach beyond the human limits, we can even hunt beasts of the highest caliber with our bare fists!" Excitedly praising augmenters, he smiled, showing his passion for augmentation, and consequently, himself.

Regardless, he continued talking about the various effects proper use of aura can increase the power of augmentation.

Nonetheless, Isaac had no issues regarding that department.

Afterwards, he moved, heading towards his dorm.

Following the GPS, he had no issues finding his dorm and placing the watch in view, giving him access.

Sitting on the couch, he sat in a meditative position, trying to find anything about aura, unfortunately, he wasn't that focused.

However, after closely studying and sensing his own internal body, he noticed a blob of dark blue energy, similar to mana, except it looked more 'physical'.

Essentially, he believed that with [Aether Body Arts] he naturally absorbed aura, like how his mana heart absorbed nearby motes of mana.

Nonetheless, he only absorbed aura when [Aether Body Arts] was active. Fortunately, he could actively use this skill at all times, which he asked the system about.

Sadly, his answer was restricted, and he didn't like that.

He could, essentially, use a technique many others struggled with 24/7? Without any side effects as well?

Odd.

However, seeing the mysterious energy simply floating there, only attracted via a technique, he remembered the previous removal of such.

If you discover this tale on Amazon, be aware that it has been unlawfully taken from Royal Road. Please report it.

Thinking, he realistically had an area to store it.

In his mind.

Recalling the two strongest techniques, he debated whether using Mana Mind with aura, naturally, he couldn't use Mana Heart twice, as that area was already being used by Mana.

However, aura could definitely be stored within his mind.

Having made up his 'mind', he called out to the system.

"System, give me the instructions to Mana Mind."

[Owner, I can deduce what you're thinking. However, Aura is not the same as mana, it is more physical, so locating in within the heart or mind can cause unpredictable issues.]

Sadly, it didn't seem possible.

Nonetheless, he asked another question.

"Are there any techniques, similar to Mana Mind or Mana Heart, except for aura users?"

[Yes, the dantian would be the preferrable option. However, I would suggest not to as the strain it would have on your soul would not be welcomed.]

Frowning, he didn't like the answer given.

"So, you're telling me not a single other soul has had access to another energy and stored it in either their heart or dantian?"

[...Well, owner, the circumstances regarding your soul are extremely unstable, for reasons that are, unfortunately, restricted.]

'Hmm? Is the soul of the original possessor of this body still around? For certain, I thought he was dead, or at the very least, gone.'

Recalling the events of his awakening, he realized that his body was relatively fine, nor was his body nor mind strained by any force.

Just knowing another soul resides in the same body he wondered if anything would happen in the future.

After all, could he, just like he did months earlier, take 'complete' control over this body?

Nonetheless, he tried to shove it to the back of his mind.

He wouldn't get an answer any time soon with the system being unable to help.

Regardless, he wanted to investigate about the overpowering force residing in his mind.

With that thought, he felt as if the original soul and force could be intertwined.

Unfortunately, before he can delve deeper, he heard a knock on his door, and by the fact that every student headed towards their new dorms, he doubted that it was a fellow peer.

Nonetheless, he headed towards the door, and twisting the handle and pulling, he was given view to a beautiful woman who looked to be in her twenties.

With beautiful white hair, filled with various purple strands, she looked ethereal in of itself. However, her beautiful facial features, like her red lips, and eyes reminiscent of the pure moon, she seemed to be the peak of beauty itself.

However, he wasn't stalled by her looks for long.

Seeing the handsome man in front of her, which she'd already seen, she spoke.

"Isaac, please head towards the principal's office with urgency." Stretching her hand, with a steel card that once above his watch, showed him a new location, she smiled at him, her eyes narrowing.

Instantly afterwards, she disappeared.

'Fuck, she's fast.'

Feeling a gust of wind, he looked at his watch, which showed a beeping dot.

With no other option, he headed towards the location.

'What did I even do?' Sighing, he questioned himself.

----

Knocking on the heavy wooden doors, which had golden handles.

Evidently, he could've pulled them and entered, however, he wanted to show respect.

Although he was talented and he could, in time, become one of the strongest entities, he wasn't there yet.

He wasn't going to act like a prick because of his potential.

To someone leagues stronger, he had no qualms showing respect, however, that doesn't mean he'll bootlick them either.

He merely didn't want to gain an enemy above his current league simply due to arrogance.

That wasn't his style.

With the high doors being slammed open, he saw someone covered in black, purple, and even tiny specks of green mana.

Evidently, he was looking at the aura of someone with the elemental control of space.

Specifically, the principal.

"Welcome, Isaac."
