The Retired Hero is an Extra

"Well, I will start today's class," Sharon began. "As you know, each spell is categorized into an element:

Fire, Water, Lightning, Wind, Earth, Light, Healing, Sound, Mental Element, Space Element and more."

Taking a timely pause, she continued, "Any spell a mage uses can be categorized under these elements. Apart from these, there are also advanced elements,

Advanced elements are a higher form of the basic ones, but lightning, mental, and space can still be considered advanced."

Taking a look around, she asked, "Does anyone know why that is the case?"

Lyra raised her hand instantaneously, so Sharon gestured for her to stand up, "Yes, Lyra Thalorien."

The whole class turned to look at her, much to Lyra's satisfaction as she nodded and began.

"Out of all the elements, those three can only be learned by people who are born with the affinity to use them," Lyra answered precisely, making Sharon smile.

"Exactly," Sharon said, gesturing for Lyra to sit down. "But there is a problem with these elements. Has anyone heard of it?"

Sharon had asked the question on a whim, not expecting anyone to know of it as the three elements were really rare, to begin with.

But to her surprise, someone raised their hand!

"Yes, Jash Ramille," Sharon gestured, not breaking her professionalism in the least.

'Ugh, I thought someone would know,' Jash lamented inwardly, having only raised his hand lazily.

He was sure that all those privileged students had a vague idea as that was why those elemental affinities weren't very much favored in noble families.

Still, he had been called and had to answer.

While all this might have seemed to take forever, all it took was the time that Jash took to lazily stand up.

"Using these elements is somewhat like killing oneself," Jash replied briefly, not interested in going over the details.

But the way Professor Sharon glared at him prompted him into doing just that.

"For lightning, controlling it is the same as trying to contain waves of water in a jar as the element itself is highly destructive and can destroy oneself if one isn't careful,"

"Then, Space and mental elements are similar, as in the amount of strain their spells put on the mind, which is considerably higher than with other elements,"

"But space element is strictly tougher than mental elements as the sub-types of mental elements are easier to master, though it's hard if one isn't talented enough,"

"Though both elements don't have many Hunters at higher ranks, even finding one at S-Rank is a miracle, let alone at higher ranks."

Jash elaborated in one single breath in a calm demeanor despite his answer not being thorough, it was enough to work with.

Yet the students around were dumbfounded as he had just called the mental element easy while the consensus was on it being difficult.

Not like it was his fault, he was supposed to have only seen Ziva use it, who did it quite effortlessly, so his words made sense.

Only he knew how much of a lie he muttered, space or mental elements weren't all that difficult in his eyes.

'The problem is someone being able to master both of them at the same time,' he mused, knowing someone like that.

They were a true monster and just so happened to be one of the late stage Villains that the protagonist only defeated due to his plot armor.

'Even then, it was at the expense of one of his harem women,' Jash scoffed inwardly as he recalled the text from the novel.

"Silence!" Sharon exclaimed to quieten the whispers that erupted because of Jash's bold words.

"You can sit down," Sharon gestured to Jash who sat comfortably, regardless of how others viewed him.

"Although he didn't explain in detail, what he said is true. Especially the space element and why spatial magic is only used with runes inside magic engineering and artifacts,"

"There are still spatial mages, but none lived a long life, reaching at most the age of their thirties," Sharon explained, looking around the class before she explained about the lightning and mental element, though briefly.

Well, she only expanded on Jash's words to give a clarification to the students before they started to look down on those elements.

"Coming back to Advance elements, there are several such elements like Ice, Mist, Magma, Plant, Sound, etc,"

"Normally, a B-Rank Hunter who is a mage can also cast Ice magic, but that doesn't mean the mage was born with an innate talent to cast said element,"

"Advance elements are all about Innate Talent. For example, I was born with Innate Talent for the Magma Element."

Saying so, Sharon raised her hand, and a ball of fire that turned into molten magma shortly after appeared in her hand.

The small ball of magma was hot enough to melt aluminum easily, increasing the temperature of the whole room instantly.

Students in the front rows felt the heat waves directly on their skin, while those in the back only experienced a slight sting.

Due to the concentration being too small and Sharon's control over it, the heat didn't radiate too fast, allowing the students to not get burnt.

And Sharon removed her spell shortly after, aware of its scalding temperature.

However, she had only demonstrated a small part of her abilities yet she could make the students gulp in nervousness.

'That was quite a show,' Jash noted, guessing the temperature to be around 700 Celsius as the melting point of Aluminium was approximately 660 Celisus.

"Apart from these elements, there is a subcategory called Miscellaneous Magic," Sharon continued her lecture regardless of the students' reactions.

"This type of magic does not fit any elemental category and is the rarest, most versatile form of magic you can have,"

"Sadly, unlike most elements, only people who are born with them can use such magic."

She seemed to have some sort of regret in her voice as she said those words before turning to look at Caera and Vivia.

"The best example is two of your classmates present here, Caera Ramille and Vivia," Sharon pointed them out.

It immediately brought all the attention to them, but the two girls didn't shy away from it.

Caera was a Battlemage and Vivia had her healing element which was considered an auxiliary element as well as part of Miscellaneous Magic.

While other elements like water, plant, wood, light and more did have healing properties, they couldn't hope to match the healing element itself.

Of course, only at the same rank, but if it was a talented person with the Healing Element, they could be comparable to one or two sub-ranks higher Healer with a different element.

Alas, the element was too rare, similar to Caera's situation of being a Battelmage.

'It's not just the two of them,' Jash mused, knowing that elves could use something like a Summoning Magic to summon magical spirits based on their mana and borrow their help.

It was different from the legend of spirits in the Elven Land as the Summoning Magic wasn't a lie, but it was just that rare to be counted as Miscellaneous Magic.

"The one who coined the term 'Miscellaneous Magic' was Archmage Christopher," Sharon said, making the students exclaim.
