"So that's what you did last time at the FDA?" Arister asked after looking around.

"Yeah" Arima answered casually "So, what is your inheritance?"

Arister smirked "[Reside in my soul and body, Ares]" He chanted and a black pillar fell from the sky, completely shrouding his figure.

Lanya, with Night in her embrace, silently retreated. While Arima looked with a smile on his expression "Ares, one of the twelve Olympians, son of Zeus and Athena's brother. Overwhelming, insatiable, destructive and man-slaughtering. That's how he is described in most occasions. The embodiment of war" He narrated while reminiscing about the Greek mythology.

When the black pillar exploded and vanished. Arister reappeared in full body armor, red and gold. He had a spear with a red blade, and large round s.h.i.+eld, planted on the ground beside him.

Arima smiled at the sight "Definitely a spartan armor" He commented and called Karma "Hey, Arister"

"Mh" Arister looked back at him.

"You wanted to learn from me, right?" Arima said "[Karma, Verto]" Karma glowed and its form started to gradually change. It became longer and the blade shorter. Ultimately, Arima finished with a spear in his hands.

He cracked his neck a bit and wielded Karma like a whirlwind before taking a stance. He waved his fingers at Arister "Come"

Arister chuckled under his helmet. He grabbed the spear and s.h.i.+eld he had beside him "Fine by me…" He paused and took a stance too. He smirked "Teacher" He kicked the ground and charged at Arima. He waved his spear at him in the same motion.

Arima made spin his pear and met Arister's at the same time. That simple clash resulted in the destruction of the earth around them, although they were just fighting with their physical strength.

Night, in Lanya's embrace looked at the fight blankly "A pair battle junkies" He commented.

"Hum, master?" Lanya called "Is it okay for me to be here?" She asked.

Night shook his head "Don't worry, these two are only using their weapons, not an ounce of mana or magic. You won't be affected, but we should get away, even if they're only fighting with their physical strength, this place won't be saved from destruction" He answered.

Lanya smiled wryly and nodded. She teleported away with Night.

Meanwhile, Arima and Arister were displaying a marvelous mastery of spear. Completely cutting off every verdure around, and deforesting, if they stumbled upon a small forest.

Arister's style was most about blocking strikes with the s.h.i.+eld and piercing with his spear. While Arima's style was very unorthodox, and maybe a bit flashy. He kept making spin his spear, not to show off, but to quickly place the blade of the spear where he wanted it to be. He also used the shaft a lot to deviate strikes coming at him.

Using this kind of style is extremely dangerous because a single error leads to the loss of the weapon. So, it can be qualified of stupid, but to Arima, it's the best style. Since a long time ago, he always has been a 'trickster' with every weapon. He never really learned any martial arts, he wasn't the kind to silently learn under someone else.

Instead, when he took a weapon in hand, he always trained alone, but not in any martial arts. He was just learning how to use the weapon by himself. With time, he created his own style, always working, with any blade possible.

When Arima holds a weapon, he doesn't need rules as to how swing it, he just moves in way that is the most logical and comfortable for him, combined with his inhuman reaction speed, he's almost invincible in close combat.

At some point in the fight, Arima planted the spear on the ground and crouched at the same time. Arister's spear truck the shaft of Karma and was blocked. Karma was also dug out from the ground and had its blade pointing at Arister.

Arima kicked the ground and grabbed back Karma while avoiding Arister's s.h.i.+eld. He thrusted Karma, with a simple piercing motion this time, and brought the blade to Arister's neck, just below his helmet.

At that instant, the shock waves produced by their movement came to a stop and the dust dispersed. Arister planted his weapons in the ground and raised his hands "It's my loss"

Arima smiled and struck the ground with Karma's shaft "Still, your armor, s.h.i.+eld and spear. It's interesting. Your weapons are something like a soul weapon. But your armor is really fascinating, most likely, even if I tried to cut it with Karma, I won't be able to cut through it so easily. It feels like it fused with your skin, no, with your own flesh" Arima commented.

Arister opened his helmet's visor and smiled. His eyes had turned golden and his hair was now red. But the thing to look at was his skin, that had changed color, and was now ash gray.

"You're right, Ares's inheritance transforms my body into a weapon. In this form, I can keep fighting with my physical body without rest" He explained.

"That's a useful body" Arima said "But you don't make enough use out of it. Also, your spear wielding is too orthodox, maybe you directly received it from Ares but it had too much flaws because you're not used to it, and also because it doesn't suit you" He declared.

"Yeah, I know that, but to be honest, Ares's spear technique is the strongest I've ever seen" Arister wryly said "And although it isn't as unorthodox as yours, it's as strong"

Arima smiled and gripped Karma before wielding it one more time "Fine, show me that technique as much as you can, I will tell you what is wrong and adjust it for you"

Arister grabbed his s.h.i.+eld and spear "My pleasure"

The two of them rushed at each other and started once again.

****************************************

"Lanya, your magic is Light, right?" At some other place, Night asked in his dragon form.

"Yes" Lanya nodded and called her rapier.

"Then you should have gained some insights thanks to Arima's lecture" Night said and suppressed his aura to the tenth level before releasing it "Show it"

Lanya gripped her rapier "[Bless my soul with your scales, Chronepsis]" She chanted and a silver light shrouded her, when it vanished, Lanya reappeared with silver scales on her body, a pair of wings and a tail. She kicked the ground and thrusted her rapier to strike Night.

Night met that strike with a great sword he created. The blade was the same as Karma, but it was just a copy of the latter made from Arima's and Night's connected soul.

When Lanya's rapier touched Karma (copy), it produced a blinding light almost instantly. Even Night was surprised by that, although he told her to use her magic, he wasn't expecting that in the first attack.

And it didn't stop there, each time their weapons touched each other, a light would erupt and perturb Night. Of course, the latter was only a bit annoyed but it wasn't enough to shock or confuse him.

So, they continued a fight like that. A silver haired girl fighting in close combat against an ebony dragon. The latter smirked "Let's start for real now" He said and his body became enveloped by dark flames.

Those flames spread onto Karma and pushed back Lanya's sword. Lanya smiled and a bright aura exploded around her. Some spheres formed above her and started shooting at Night with some beams.

She also started conjuring rays of light that attacked Night each time she struck with her rapier. After that, it turned into an orthodox fight, fire and light were flas.h.i.+ng everywhere, burning and destroying everything around.

Night seemed to be enjoying the fight and Lanya had a serious expression all along. The former grinned and waved his weapon in a strong motion. Lanya couldn't take it head on and retreated. At that moment, Night raised his palm toward the sky.

"[Adolebitque visus est omne in cinere] (Burn everything in my sight to ashes)" He chanted and a huge fireball formed above him.

Lanya gripped her rapier and starting using it as a pen to write on mid-air "[Light, gather and burn anything under your illumination]" She chanted and a sphere of light was conjured at the tip of her sword.

Night grinned "[Fifth blue art, Inferno]" He chanted and threw the fire at Lanya.

"[Unbreakable Light]" Lanya followed and the light at the tip of her blade launched itself toward the huge fireball as a white beam.

When the two magics touched each other, an explosion instantly occurred, the first shock wave crushed the earth for miles around. The fire and light brought by the explosion dug out the earth and created a crater.

But, the fire ultimately won against the light and the last shock wave was sent against Lanya, but it didn't inflict any damage to the latter.

"Why?" After the discharge and when the two of them were looking at each other, Lanya raised her voice "The magics we sent were of the same magnitude, why did I lose so clearly?" She asked, her actual expression was a lot fiercer than usual.

Night smiled wryly "'Fifth blue art'" Night repeated himself "That's the magic I used" He answered.

Lanya frowned "What is it?"

"The Kind Demon's Arts. That's how Arima calls it" Night answered "He created twenty-five arts separated into five categories, blue arts, red arts, white arts, black arts and destruction arts. That's one of the theories he created, a set of magics, since they were thought in a really precise way and are bound by specific rules and chants, they are more powerful than most magics of the same magnitude" He explained.

"The Kind Demon's Arts?" Lanya quoted and almost laughed "Did Arima really call it like that?" She asked with a smile.

Night laughed "Of course, I forced him a bit, but he accepted in the end, he said that it was only because it worked well for a set's name" He said and shrugged.

"Each category has five magics, going from the fifth art to the first art. Of course, it's stronger as you go up. What I will teach you now, are the fifth arts of each category, I think it's good to begin. The other advantage of that set is that the requirements of element affinities are not really important" Night explained and readied Karma.

The dragon smirked "I will teach them to you while we fight" He said "Bring it on, you improved greatly since the first time I fought with you, it's time to continue on that way"

Lanya breathed in and gathered light around her, her rapier became shrouded in the same glow. Her body started becoming fuzzy as she vanished soon after, she directly reappeared in front of Night and attacked one more time.

******************************************

A few hours later, Arima and Arister's spar was meeting its end.

When the two of them were around fifty meters apart from each other. Arima took a throwing stance and threw Karma like a javelin toward Arister.

The latter used his s.h.i.+eld to block Karma, but the strength hidden behind the spear surprised him and he was pushed back by around ten steps.

When he moved his s.h.i.+eld to look at the front, he noticed that Arima was just beside him "[Terminus Confractus, C] (Limit Break, 100)"

Before he could react, Arima span and kicked him in the abdomen. That single kick was so heavy that Arister coughed some blood before turning into a human cannon ball, and flying away.

When he crashed on the ground and created a new crater, Arima was already pointing Karma at him while casually standing beside him.

Arister, raised his head at bit then looked at Arima, after that, he relaxed his body and completely lied down "Okay, it's my complete loss" He said and his armor and weapons faded way.

Arima smiled and gave him a hand to stand up "That was your last lesson in this fight, if you see an occasion, you can discard your weapon temporarily and use you body instead" He said.

Arister chuckled and stood up to stretch "Sure, teacher" He said, a bit sarcastically.

"Well, let's go, I want to sleep now" Arima said and teleported where Night and Lanya were. Arister shrugged and followed him.
