Since they're some new faces around, It will be better for them to at least learn about the basic of magic. Apparently (and obviously), the knowledge I received from the goddess and their understanding about magic is quite different. Can't blame them since unlike me, they're all researching about magic to be applied into their daily lives. I mean, for comparison sake, if by chance the god gives me scientific knowledge back on earth and I can suddenly make a rocket that can travel to Mars within an hour, those back on earth will have their jaw dropped to the floor.

"But Brother Ash, I'm not sure I can do that" (Plus, teaching a princess is without a doubt, a big job. Someone like me couldn't do that!) [Kara]

"Don't worry, I'll help you. You just have to tell them the basic and if by chance you make a mistake or forgot some part of it, I'll make sure to step in" [Ash]

"But..." [Kara]

"You can do it!" [Ash]

"Fine..." (I give up) [Kara]

Kara isn't that much of a shy girl I believe, it's just that how society have been treating her and her twin Mara being more extroverted causing people (and probably she herself) seeing her as introverted. 

(Plus, she does show an interest in learning and teaching area, so this will be a good first step) [Ash]

Looks like she's mustering her courage to speak. 

(You can do it!) [Diana]

That's what probably Diana's eyes telling Kara right now

"Good evening everyone, I'll be... I'll be teaching you guys about the basic of magic" [Kara]

"Yes" [Centaur boy]

"Please teach us" [Little girl]

"I'll do my best" [Kara]

She takes a deep breath and

"As you all know, magic is a phenomenon that happens when one channel their mana from within their body, or more specifically from inside their cells to outside the cells, and that's include our own body as well" [Kara]

"Cells?" [Clothing shop aunty]

"They're basically this really, really really tiny block that make us. Think of it like those bacteria that caused the endemic disease, only this time, their function is to make us" [Ash]

As I said that, I make an illusion magic showing the typical cell structure that we use to draw inside classroom. It's looks like they understood the explanation

"Thank you Brother Ash. Now, the mana that one contain is actually determined by the number of special organnelles in cells call Mitral. One who's born with high amount of mana will usually have high number of Mitral inside their cells, but not to worried, one can simply increase their number through training" [Kara]

"First I heard of Mitral" [Qis]

"Same here" [Diana]

"Umm..." [Kara]

"Don't worry, I can assure you that's correct" [Ash]

Well, information from Goddess Achalasia herself wouldn't be wrong

"And to top it all. Mitral will consist of a central neutral core surrounded by the seven element peripheral core which corresponds to the seven basic elements in this world, Fire, Water, Earth, Air, Light, Dark, and Mirage" [Kara]

As Kara said that, I'll illustrate the Mitral Organnelles through my illusion magic to make it more understandable

"The neutral central core of Mitral usually can be utilized by two means. One is by using it directly and thus producing the neutral mana magic which without exception, can be used by everyone. This neutral mana can either be used directly or can be channel through number of different form of magic, for example racial magic. For example, a Dracula can channel his or her neutral mana which is converted into racial magic and infused it into their bloodstream to enhance their vitality" [Kara]

"How about the human race?" [Lisa]

"Human race doesn't have any special racial magic, but they're able to utilize almost all the other other racial magic to small degree. The same vitality magic in Dracula for example can be used by human to look younger, or the beastly enhancement magic can be used by human as Berserker magic or it's higher variant, Amok" [Ash]

Since Kara can't answer that part confidently, I help her, she looks relief but I just ask her to continue the teaching session

"Now, the second use of neutral mana magic is to convert it into the seven elemental magic by channeling it into the peripherals core of the Mitral" [Kara]

Kara then proceeds to use wind magic on her right hand and light magic on her left hand. I don't know why she does that, maybe it's just to emphasize her point.

"This two is the elementals magic that I'm good at, but..." [Kara]

She then switched the magic in her hand into Earth magic, albeit only a tiny amount of dirt comes out 

"According to Brother Ash, my earth magic affinity is low, but I'm still able to use it albeit not as good as Karon" [Kara]

"So that mean you have three affinities?" [Kat]

"No, what we call affinity is simply the number and strength of peripheral core inside the Mitral. Here's the catch, I could technically and theoretically use all seven type of elemental magic just like Brother Ash, since all of us have the seven peripheral core surrounding the Mitral Organnelles" [Kara]

"!" [Others]

Haha, I swear to god, this is exactly how those siblings of mine react when I told them for the first time.

"That mean that I can use all type of elemental magic as well?" [Neighbors kids]

"Technically yes, if you work HARD enough" [Kara]

"That sound discouraging" [Mile]

"It sure is" [Blanc]

"How about the thunder magic? Lava magic and other? Where do it come from?" [Neighbors kid]

"They're simply a combination of other basic elements" [Ash]

"Now, coming back to our topic, what we call affinity is simply the number and strength of our peripheral core. As for me, the number and strength of my peripheral core is mostly wind and light and thus I'm able to easily utilize those two magic easily as compared to other type of magic. While it's technically possible for me to use other elements, it's just way too hard that it would not be worth it as the number and strength of other cores are simply not enough to sustain that element" [Kara]

"So wait..." [Samurai Jacks]

"Does that mean..." [Syah]

"Ash have..." [Diana]

"Yup, I have equal number and strength of all seven elements of peripheral core surrounding my central neutral core" [Ash]

"And that allow you to use all type of magic" [Mimi]

"That's correct" [Ash]

And once again their jaw dropped. It is to be expected

"Now, how about we move on into the next topic. Basic of using magic, and I'm sure all of you are wandering the same thing, how to use the chantless magic!" [Kara]

"Ohhh!" [Ray]

"She's enjoying this" [Mara]

"She sure is" [Rean]
