Dragon Slayer Magic

Aibo might have learned Dragon Slayer Magic, but it was unlikely that Aibo had learned Dragon Slayer Magic.

Natsu had only taught Aibo for one day before Aibo gave up on him.

His teaching method was basically, "Do this and this, then that and that, and then do this and this, and finally cast the magic." No normal human could possibly understand it. It was not even like playing music to a cow—it was the cow playing music.

Fortunately, Aibo had a cheat. He still managed to light up the skill [Dragon Slayer Magic LV0: 0.1%].

Then he encountered magic that was even harder to learn than Crush Magic.

After practicing in a highly abstract manner for several days, the experience bar had not moved one bit. He had no idea whether Natsu's teaching was nonsense or whether the magic itself was simply absurdly difficult to learn.

But it did not matter. Aibo had a cheat.

He spent 1,000 Inspiration Points to raise Dragon Slayer Magic to LV1, and then... something happened that Aibo could not understand.

[Dragon Slayer Magic LV0] vanished, becoming [Enchant Magic LV1] + [Heteromorphic Magic exp +1000] + [Dragon Seed: 0].

Aibo was full of question marks. Enchant Magic... he seemed to have seen it mentioned in some book before. He could understand gaining 1,000 Heteromorphic Magic experience, but what the hell was this [Dragon Seed]?

Aibo had heard Natsu explain that Dragon Slayer Magic allowed humans to possess Dragon Power, transforming their physiques toward those of dragons. It was magic used to kill dragons.

But now Dragon Slayer Magic was gone from his skill list, so he could no longer gain experience through practice.

After spending the Inspiration Points, Aibo had grasped the principles behind Dragon Slayer Magic. Based on his understanding... without this "Dragon Seed," it was impossible to learn Dragon Slayer Magic.

The sky had fallen. Aibo was speechless. He had no solution.

"Aibo! Aibo! Waaaah!"

Before she arrived, her voice did. The door was slammed open by a white-haired beauty dressed all in black. Mirajane, with snot bubbles at her nose, threw herself at Aibo and burst into tears.

"??? Mira? What happened?"

"Waaah... I'm telling you... Elfman... Lisanna... they did it for me... Take Over Mag... how can they... be so nice..."

Mirajane babbled incoherently between sobs, but Aibo still learned the whole story from her thoughts.

It turned out that Elfman and Lisanna had secretly learned Take Over Magic so that Mirajane, who was "playing the aloof type" at the guild, would not feel lonely. They had just surprised her with it, and Mirajane had been moved beyond words.

Mirajane was stubborn and thin-skinned. Too embarrassed to cry in front of her younger siblings, she had actually run away and come to his house to cry while hugging him.

Aibo did not know whether to laugh or cry. Ever since Mira had revealed her other side to him, she had become increasingly uninhibited.

At the guild, Mira was still that arrogant, forceful delinquent girl from before. After falling out with certain people and feeling humiliated by it, she often sat alone pretending to be cool.

Yet in private with Aibo, she became a little girl who liked hearing him call her big sister. She even treated him like an emotional dumping ground and safe harbor, coming over to bother him whenever she had the chance.

At the end of the day, she was still an immature little girl who happened to be at that embarrassing age.

To be honest, Aibo was already getting a little tired of her.

"Alright, alright, stop crying. You ran off like that—Elfman and Lisanna must be heartbroken. They should be the ones crying, shouldn't they?"

"They would not! Don't underestimate the bond between me and my siblings! And hurry up and call me big sister."

"No. I do not have a big sister as embarrassing as you."

"If I can't be your big sister, I can be your little sister instead! Aibo, turn back into your fifteen-year-old self and let me see~ I can call you big brother too, heehee."

Mira pinched the soft flesh on Aibo's face, grinning happily.

Strictly speaking, Mira had never really changed. Her little devil personality had always remained the same. She had merely thrown away her "big sister burden" in front of Aibo, given up entirely, and could not even be bothered to pretend anymore.

In some ways, Mira and Aibo were quite alike. Both were used to living behind masks, both enjoyed seeing others make fools of themselves, and both were Family Heroes who cherished their current family deeply...

Perhaps because they were "the same kind," Aibo did not bother pretending to be a child around Mira either. The two of them got along very casually.

"Stop bothering me. I'm not as free as you are. I need to study magic, so get lost, get lost."

"How heartless! How cruel! I shared my happiest feelings with you first thing, you know! And you're driving me away!"

"...Then I'll leave?"

"Ehh~ But I'm about to head out alone for a commission. Before I leave, I only wanted to spend this precious time with Aibo, sob sob~ I'm such an annoying pest, I understand. I'll leave quietly."

[Come comfort me! Call me big sister! Hurry! Come on!]

Mira theatrically wiped away her little pearls. Her eyes, visible through her fingers, shone like tiny lightbulbs. Aibo was so irritated that he laughed. How exactly had this idiot child's brain developed?

"Let me see your guild mark."

"Eh? What for?"

Mira lifted her slender leg in tiny shorts. Her mark was stamped on her thigh, and she had even chosen pink.

"I'm adding another mark."

Aibo pressed his hand against it, leaving behind his Flying Thunder God mark.

"...Since you have nothing better to do, help me study magic here."

"Okay, okay! I can stay with you all day!"

Aibo did not have many ways to deal with Mira, so he might as well use her for an experiment.

Although the [Dragon Slayer Magic] skill had disappeared, the knowledge he had acquired had not. He had more or less understood the principles behind Dragon Slayer Magic.

Dragon Slayer Magic was a composite magic. At its core, it drew "Dragon Power" from the "Dragon Seed," converted it through Heteromorphic Magic into magic power with a specific special attribute, then used "Enchant Magic" to attach its "dragon attribute" to the human body, allowing humans to possess Dragon Power.

So in essence, Dragon Slayer Magic was an application of Enchant Magic. However, its creator had been exceptionally clever. Like Celestial Spirit Magic, they had programmed all the intermediate steps, so muscle-brained wizards like Natsu did not even know they could use Enchant Magic.

Enchant Magic was a type of magic that could directly grant objects or human bodies all kinds of magical effects. In Aibo's understanding, it was like applying buffs—and permanent buffs at that.

Dragon Slayer Magic could continuously attach the Dragon Power within a "Dragon Seed" to the human body. Theoretically, whatever attribute the Dragon Seed possessed determined the only attribute of Dragon Slayer Magic one could learn.

For example, Natsu definitely had a fire-attributed Dragon Seed, which was why he was a [Fire Dragon Slayer]. The flames he usually ate were not actually digested in his stomach, but stored within the Dragon Seed in his body.

Aibo, however, had no Dragon Seed. He possessed neither Dragon Power nor the ability to store special elements inside his body, so he could not use Dragon Slayer Magic.

This was the first magic Aibo had ever encountered that he could not learn. If he truly wanted to continue studying Dragon Slayer Magic, he would first have to find a "Dragon Seed" containing Dragon Power?

Aibo had no clue where to begin for now, but he could test the effects of Enchant Magic first. This magic seemed even more exciting than Dragon Slayer Magic.

LV1 Enchant Magic seemed capable of attaching certain elemental effects to the human body. So Aibo took Mira's hand and attached the light element to her palm.

Then Mira's hand "lit up," radiating dazzling light.

"Eh? What is this? My hand is glowing!"

Every magical element had certain fixed properties. Fire had "burning" and "scorching heat," ice had "coldness" and "stillness," earth had "solidity" and "heaviness"...

The properties of light were "brightness" and "extreme speed." Its damage might not be high, but it was definitely fast.

"Let's go outside first..."

Aibo took Mira to the edge of the forest and pointed at a large rock in the distance.

"See if you can fire the light from your hand at it?"

Mira pondered for a moment, then threw a punch with her glowing little fist.

Aibo could feel her magic power turn into a golden fist-shaped beam that shot out and struck the distant rock with a dull thud.

"Cool! It seems... not that hard?"

"Interesting. Let's try again!"

Aibo pressed both hands against Mira, turning her entire body into a sparkling "light person."

"You've been enhanced. Go! I choose you, Mira! Use light-speed attack!"

"..."

Mira found it a little strange, but she still followed his instructions. She stepped forward, and in the next instant, she appeared before the large rock. One punch shattered it into pieces.

Mira stared blankly at her fist, then suddenly screamed.

"Wah! Ow, ow, ow! It hurts!!!"

Mira clutched her little fist and hopped around in place, tears welling in her eyes as she looked at Aibo. Yet she saw not a trace of concern or sympathy in his eyes—only excitement and exhilaration.

"So fast! That movement just now should have been the maximum speed your body could withstand. With that speed stacked on top, your fist unleashed power far beyond normal. Luckily, your body is tough enough. If it were me, I'm afraid my wrist would have broken. Is this Enchant Magic really that powerful? Come on, let's conduct the next test..."

"W-Wait, Aibo, I suddenly remembered that I seem to have something to do..."

"Mira, big sister?"

"Please give your big sister all the orders you want!"
