While I was cooking lunch Akari would constantly ask if I needed any help since it looks like it would be difficult with only one hand but I just tell her 'If I can't even cook for my little Akari how can I call myself a big brother?'.

After a while, Akari finally gives in and sits in the living room looking towards me watching me and my cooking skills in action!

While she's not paying attention as much, I sneak in some herbs and spices from my [Pocket Void] to add some flavour to the meat.

After a while, we finally dig into a Wyvern meat hamburger that makes Akari's eyes sparkle and asks countless questions like 'Hey hey, how did you make this?' and 'Where did you get this delicious meat?'.

While washing the dishes, I start to think about ways to make money other than selling some of the gold I brought over.

Since I've decided that I want to use my hobby of inventing magic imbued items and selling them in secret I'm going to need a store.

However, I can't just call it a magic store or something like that, and I need to be an actual business that sells normal things.

Not only that, even if I had no knowledge of people with magical abilities on earth, that doesn't mean there aren't any.

So if possible, it might be worthwhile to attract those people behind the scenes and see if I can learn anything about them if they really exist.

It might be fun to discover some secret organisation with the mage's who research and have magic battles or something.

Maybe they have much more developed magic capabilities since on earth we have the knowledge of science.

Since I had the best affinity with mana and also had the largest mana pool on earth, doesn't that simply mean that there were others who also had these mana pools with capabilities to use magic?

Being able to sense mana and use it are usually talents that are gained from birth due to blood lineage. 

Sometimes there are rare occurrences when someone is born with an abnormal mana pool and affinity.

I can be considered that abnormality since I was born with such a mana pool, but what about Akari and my parents?

Now that I think about it since I have such a large mana pool and affinity wouldn't Akari also have the capabilities to use mana?

Anyone and everyone can use mana since mana is said to originate from living things. 

However, not all living things have a strong enough perception towards the mana within themselves and around themselves to even sense it.

These traits are passed down to their children and it usually never changes unless mutations occur such as me.

Even if I am an abnormal existence on earth, Akari is directly related to me with blood so she should also have the capabilities of sensing mana and using it for herself.

If Akari is really able to use mana, I honestly would try to teach her how to use it every day.

I can just imagine Akari spinning around in some kind of witch outfit you can find in an anime and start chanting spells.

Not only would that be terribly cute, but if it's my little Akari I would have trouble trying to keep in my laughter imagining seeing such a thing.

"Hey, what are you smirking out over there?"

Ah, I've been caught by Akari while imagining such things. 

This story has been unlawfully obtained without the author's consent. Report any appearances on Amazon.

I grin at the thought of what the future might entail and the interesting things that might occur.

That's it.

I've decided!

I'm going to turn Akari into a magic girl!

Finally finishing up my chore, I walk up to Akari with a smirk on my face.

"W, what is it onii-san?"

Akari looks up at me with a somewhat scared expression as she leans back on her chair to get some distance between us.

"Hey Akari, do you think magic is real?"

Akari's once scared expression starts to fade away as she just becomes confused from my question and tilts her head.

"What do you mean? Like pulling a rabbit in a hat?"

"Mmmm. Not like that but similar."

"..Of course, magic isn't real onii-san, what are you trying to say? Do you think I'm an idiot?"

I just laugh at her which causes Akari to become somewhat angry.

"Do you want to see your big brother do magic?"

"I'm not a kid onii-san! I know magic is simply just tricks and illusions. What are you playing at?"

"Don't you trust your big brother? Just sit down and watch me use some magic. Tell me if you can notice anything alright?"

With a confused expression, she nods and sits patiently and stares at me trying to see if I'm going to trick her with that fake magic.

Taking a step back, I will some mana from within my mana pool and send it to the tip of my finger before chanting within my mind creating a ball of water to float above my finger.

"Hey Akari, is this magic or some form of illusion? Come here, try touching it."

Akari just stares at the ball of water slowly rotating above my finger with a bewildered expression. 

I move closer to Akari to let her have a closer look at the water ball that is defying both gravity and the laws of the world.

"What is this!? Is this water? How..?"

"It's magic, didn't I tell you? Did you think your big brother was trying to impress you by trying to perform some fake magic? Here, watch this."

I start to will my mana and change the ball of water to a flame, then to a light, wind, and a rock.

Although I make it look simple, this process is actually really complex and inefficient for using mana but I'm just using it for the show.

To explain what mana, affinities with it, and what magic is can only be explained with what pure mana is.

Pure mana is a metal alloy, it is different types of elements fused together to create a balanced energy.

This magic alloy, for example, is made of 4 parts.

Fire, Water, Wind, and Earth.

Pure mana is the collection of these elements in an equal ratio. Mana=4 F,W,W,E=1 Part of 4.

Pure mana does not affect anything and can be simply said to be in an idle state.When casting magic, you are simply extracting one of these affinities out of the pure mana and

This is because the elements that create this pure mana negate each other similar to yin and yang.

When casting magic, you are simply extracting one of these affinities out of the pure mana and separating meaning that the energy that was being negated is activated once again.

Even if you are able to extract these elements out of pure mana, it doesn't have a purpose so it either dissipates or goes back into it's negated state.

With spells, the extracted element is forced through a certain pathway or magic circle which simply 'codes' the mana to the user's desire.

When someone is born with a strong affinity with fire, this means that the mana pool they are born with favours fire over the other elements.

Mana 4: Fire 2: Water 0: Wind:1 Earth:1

This is what it means to have a stronger affinity with fire.

Having a strong affinity for an element isn't always a good thing since.

For example, someone with the affinity of Water with the ratio of 3, can cause an excess amount of water appearing when using a spell without the right control.

With this, whenever that someone tries to use a basic spell to conjure water, instead of being greeted with a small glass worth they create enough to create a small pond and can die from excess use of mana even if it wasn't on purpose.

Another term for affinity in these elements would be the 'gate' in their mana pools.

The door to use water would be larger than other peoples in this sense as the other three doors for the elements allowing for pulling out the affinities are smaller.

This is the basics of what mana, magic, and what inborn affinities are.

Although there are much more different elements in mana, this is just a simple and basic introduction to what mana truly is.

This is what I've decided to teach Akari if she does possess an innate nature to sense and use her mana pool.

"Akari, if I told you that you can do something like this too, would you want to try?"

Still bewildered and confused from the sudden use of magic, she blinks at my question as if saying 'Me too? I can do this too?'.

"..Is this really magic..? Why do you know magic..?"

"Don't worry about those things, and yes this is real magic. Do you want to do something like this too?"

Although she looks like she can't really understand the current situation Akari does still consider the possibilities of using the so-called 'magic' I have shown her.

Nodding after her decision is made, "...Although I don't really understand what you're really talking about with this magic, If I can do something as cool as this I want to do it too!"

Akari looks towards me with sparkling eyes as if saying 'I can't wait to learn magic!'.

That's it, I've decided!

I'm definitely turning Akari into a magic girl!

Well not literally.
