In this world, a miracle will be created when a process of uniting two energies occurs, namely "mana" and "etherion."
Mana is the energy contained within the body of living beings, while etherion is the energy spread throughout the entire world.
When these two energies merge, a mysterious phenomenon is formed, and that mysterious phenomenon will manifest according to the will of the source of Mana energy.
There are several ways to unite these two energies, such as alchemists, artifacts, runes, and some strange techniques from the east. But the most common are two: magic and aura.
Magic occurs when Mana from within a living being flows out and merges with Etherion in nature.
Meanwhile, Aura occurs when natural energy, Etherion, is drawn into the body of a living being and merges with Mana inside the body.
Not everyone can use magic or aura.
Although all living beings in this world possess mana, not all of them can interact with etherion.
An exception is the elf race; in this world, it is as if they are destined to have an affinity with mana and etherion.
The same goes for some types of demons.
**********
That was a brief introduction about magic by Magnus.
"Now close your eyes."
Following Magnus's instructions, we began closing our eyes.
"Concentrate and focus your mind and senses on your chest, because that is where Mana gathers. Then, imagine something warm within your chest."
After following his instructions for 30 minutes, I could feel something warm inside me.
I deployed the nanobots to identify it.
[Detecting_error]
I opened my eyes and saw that the others had also opened their eyes.
"Were you able to feel it?"
Hearing Magnus's question, we nodded.
"Good, that is Mana. Remember that sensation. Concentrate again and imagine the energy from your chest flowing into your palms while picturing a ball of water."
I tried to move the energy as instructed by Magnus, but it was truly difficult. For 2 hours, I still couldn't flow it into my hands, and I felt exhausted.
"If you feel tired, take a rest."
In the end, I gave up.
"Haa~ haa~, just a little more, but I can't do it anymore."
What the heck is this! This is really exhausting, both mentally and physically, and my head feels painful.
"Rest, Flitz, the first attempt at using magic consumes a lot of energy. It's already quite good that you endured this long."
Hearing Magnus's words, I looked around and saw that the others had also become exhausted and stopped trying to channel their mana, except for Agatha.
Covered in sweat and breathing heavily, Agatha was still trying to flow mana into her palms.
After a few minutes, Agatha opened her eyes and asked Magnus.
"I finally managed it, haa~ Master Magnus, haa~ what should I do now?"
"Release the energy from your palm into nature and say the chant [WATER]!"
Magnus quickly replied.
Hearing that, Agatha extended her hand and spoke the chant according to Magnus's direction.
[WATER]
From Agatha's palm, a small water ball was formed, slowly expanding. After a while, the water ball burst and spilled onto the floor.
Ooh!! That was an impressive sight. So this is magic... I've never actually seen magic being used before.
After that, Agatha collapsed in exhaustion with an expression of joy.
"Haa... haa..., I did it!"
"Hoho, I didn't expect someone to succeed on their very first attempt."
Hearing that, I turned and could see Keil and Anna with shocked faces.
It seemed this really was a rare occurrence. Could Agatha be called a genius in magic? Or was it just coincidence?
We applauded Agatha's achievement.
"Agatha-san, you're amazing."
"This is the first time I've seen someone do it on their very first attempt!"
Hearing Princess Adelia's surprise, Kushida became more excited.
"Really? Agatha-san, are you a genius?"
Hearing everyone's praise, Agatha smiled shyly.
**********
"Alright, our lesson for today is enough. We will continue tomorrow."
After Magnus gave us some knowledge about magic, he ended the lesson and allowed us to leave the class.
Before leaving, Haru and the others told Magnus about the awakening of their powers.
"Hmm, I see. Thank you for telling me."
He pondered for a moment, then shook his head while saying,
"Unfortunately, it seems you'll have to develop your powers on your own. I don't know anything about the powers of beings from another world... but I will help you. If there's anything I can do, don't hesitate to reach out to me."
After a short talk with Magnus, we left the classroom.
**********
After teaching basic magic, the three mentors walked together back to their place.
Keil started the conversation.
"That was really amazing, being able to use magic on the very first attempt."
Keil recalled the earlier event, when one of the heroes named Agatha managed to use magic on her very first try.
He was truly shocked when Agatha succeeded in using magic.
In this world, being able to use magic requires at least a week at the fastest.
While stroking his beard, Magnus said,
"I think the other heroes will also be able to use magic in one or two days."
Hearing that from Magnus, Keil was shocked again.
"Seriously!!"
If it were anyone else, Keil probably wouldn't believe it, but since it was about the heroes, that was a different matter.
Besides, the one saying it was Magnus, one of the strongest witches.
Feeling relieved, Keil spoke about Princess Adelia.
"Thankfully, Princess Adelia has been learning magic for the past few days, so she won't fall too far behind."
When the heroes first arrived, the princess begged the king to let her study magic.
Although at first King Cyrus opposed it, with the princess's persistence, he eventually allowed her to learn magic.
It wasn't without reason that the king opposed it. Unlike other races, humans can only use mana within their bodies once they reach the age of 8.
For nobles, it isn't until the age of 14 that they are permitted to practice magic.
Why must they wait 6 years before using magic? It's because the flow of mana in humans is very unstable at first, requiring 6 years for mana within a human body to stabilize.
If a human forcibly uses magic before the proper time, except in some cases, they could suffer severe injuries.
That's why nobles take this matter very seriously.
And that was also the reason why the king opposed his 13-year-old daughter's request.
"That's why we really needed you in class this time, Anna."
At first, the king didn't want the church to be involved with the heroes during the agreed six-month period.
But seeing his daughter about to study magic before her time, the king finally approved the church's proposal to teach holy magic to the heroes.
With the condition of guaranteeing the princess's safety from the consequences of using magic.
Knowing this condition, the church sent one of their best priestesses, Anna.
Hearing her name mentioned, Anna glared at Keil coldly.
".... You'd better not speak to me, traitor."
Hearing Anna's cold response, Keil sulked.
"Come on! Don't say that.... Haa~ I miss the old you."
"....."
Keil remembered the past, when Anna used to call him big brother and always followed him everywhere with a smile full of joy.
But that was already over because of that incident. Look now! She looked at him as if he were a sinner, though it wasn't entirely untrue.
".... Alright then. See you tomorrow. Excuse me, Master Magnus, and you too, Anna."
After saying that, Keil turned and left Anna and Magnus.
Seeing his departure, Magnus spoke to Anna beside him in a tone of advice.
"I hope you can treat Keil better. He must have his reasons."
"...."
Anna did not respond to Magnus's words. She only continued to gaze in the direction Keil had gone, her expression blank, with no one knowing what she was thinking.
**********
After returning to his room, Fujita was still thinking about Flitz's soul that he couldn't see.
And not only that. He was also confused about why, when Flitz approached Haru, the color of Haru's soul dimmed as if it wanted to hide from his sight.
But when the two of them separated, Haru's soul returned to normal like other souls.
Fujita found no similar cases with anyone else when they approached Flitz.
But more than all that, he had a strange feeling about the red-colored souls.
Somehow, Fujita felt that those red souls carried an unpleasant feeling.
