Magic Has Seven Attributes?! That Is Hearsay!

"So, what do we do first?"

Currently, Touya, Lindsey, Elsie and I are in the backyard of the inn. Just in case, I have given the inn advanced payment if Touya accidentally breaks some objects from his magic lessons.

"Ah, yes. Let's start with the basics, however... there are several [Attributes] in magic."

"Attributes?"

"They're things like fire and water. Etto, altogether there are 7 attributes which are fire, water, earth, wind, light, dark, and null."

Lindsey explains the attributes of magic but I interrupt her since her explanation is wrong. No, more like this world's magic system is wrong.

"Magic has 7 attributes?! That is hearsay!"

"Eh?!"

After I interrupt Lindsey, Touya, Elsie, and Lindsey shout in unison as they are shocked at what I have just said.

"Before I explain, I might as well ask this question. How old am I?"

The three of them observed my appearance first before telling their guess.

"14."

"16."

"18."

Elsie, Lindsey, and Touya tell their guess about my age.

"Wrong!"

As I say that, the three of them are wondering how old I am.

"How old are you?"

"Ten billion and eighteen years old."

I answer Touya's question.

"Eh?!"

The three of them shouted in shock once again.

"I am from a race that possessed infinite lifespan and immortality. Hence, I am immortal."

I say as I behead myself using my right hand while holding my head using my left hand. Golden-colored blood drips from my neck. In an instant, a new head is regenerated from my neck but without a blindfold.

I take the white blindfold from my dead head and equip it to cover my eyes. I didn't open my eyes so they didn't know about the color of my eyes.

I store my deadhead on my yin-yang ring and I decide to dispose of it later.

"But, I mostly lived in seclusion until my grandfather told me to take care of my little brother Touya. A million years ago, the attributes of magic weren't 7."

I explain to the three of them as if beheading my head didn't happen. Touya knows who the grandfather I am talking about so he didn't ask any questions about him.

"If magic doesn't have 7 attributes, then how many?"

Lindsey asks in curiosity. Among the two twins, Lindsey is the most interested when it comes to magic so she didn't hesitate to ask me a magic question.

"Including the 7 attributes that you have mentioned previously, there are space, time, life, death, soul, body, mind, and anomaly. In total, there are 15 magic attributes. Elsie's body strengthening magic is in body attribute, not null attribute."

I explain to Lindsey, Elsie, and Touya.

"Seref-sensei, please teach us magic!"

Both Lindsey and Touya yelled at the same time while performing a 90 degrees bow.

What is this situation? Lindsey was supposed to teach Touya magic so that their relationship will improve but now I am the one who will teach the two of them about magic?

"I will..."
