Demon Lord's Reincarnation

Seeing the hero's body turn into white orbs of light Kretos was amazed. He touched the white orbs and noticed that they were a pure form of mana, the purest he has ever felt. It was at that moment Kretos had a very intriguing thought.

'Was the hero's body constructed wholly by mana? He had no real physical presence in this world, is that why I couldn't harm his body?'

Kretos looked at the fading lights and started to smile viciously at the heavens were the white lights were heading towards.

'Heroes are more interesting than I thought. I wonder how his body was constructed, was that his actual body or was that a body created for him to assimilate into this world?... If that's the case then that would mean someone had the power to create a body of pure mana.'

Kretos looked at the fallen companions of the hero, his sight naturally focused on the supposed mage that controlled and summoned the hero, Jeter.

'With this guy's abilities, he shouldn't even be able to use a true top tier spell, much less a miraculous spell that creates a human body of pure mana... The only beings I can think of that could do such a thing are deities. Does that mean deities are real? I wonder how strong they are, fighting such beings should be a wonderful experience.'

The moment Kretos thought that deities were real, he immediately thought of fighting them and these made Kretos smile even more viciously. As he was getting engrossed in his excitement, Kretos finally remembered that there was another delicious meal waiting for him.

"I hope that naughty fox doesn't eat everything before I get there." As he was about to leave Kretos once again looked at Jeter.

'Should I kill this fool? Sora only said I should spare the three... I guess I can let him live for now. If he's able to survive until later he might be able to summon another hero, that would be fun. Though I doubt his companions would even allow that.'

Kretos shrugged his shoulders and no longer bothered with the four unconscious men and left the mountains.

...

In the Canyon linking the Sliral Kingdom and the demon lands, a fifty thousand strong army was marching towards the demon lands. There were heavily armored knights, lightly armored knights, Knights on horses, mages, and healers.

They also brought a lot of siege weapons and enough supplies that would last them a year. This was the ever-victorious army of the Sliral Kingdom.

At the distance, Tsukiko looked at the rather impressive formation of the human army and giggled. "At a distance, they look like a snake made of steel."

Tsukiko looked at the demon tribes that were available to face the approaching army. Compared to the menacing fifty thousand strong armies of humans, the demons only amounted to ten thousand. Also unlike the humans, the demons were ill-equipped, also another thing worth noting was that these demons were from the weaker tribes in the demon lands. The stronger ones were still busy waging war against those that defied Kretos's rule.

'Well, it doesn't really matter all they need to do is kill those that I miss. It has been a while since I last took to battle... Hmm... I wonder, why am I actually feeling a bit excited about this? Is it because of that guy's influence?' Tsukiko then imagined the vicious smiling face of Kretos and smiled sweetly. 'I guess I did get some bad habits from that guy... Well, no matter I better finish this quickly before he gets here. I wonder what kind of face he would show when he arrives and there isn't any left for him?'

Just thinking about the face Kretos would make, made Tsukiko smile a bewitching smile that affected some of the male demons present in the field of battle. Tsukiko then looked at the demons who came to fight and spoke to them.

"All of you don't need to do much. Just kill those that get past me or try to escape. Aside from that just try to stay alive."

The demons saluted Tsukiko and got ready for the upcoming battle. With a former demon lord such as Tsukiko by their side, the demons felt like victory would be easily achieved. Well, they still felt like they would be victorious even without the help of a demon lord. Despite the humans having superior numbers and equipment, in the end, they were still human.

...

When Tsukiko saw how eager the demons were to head into battle, she nodded her head and started circulating her mana. She then shouted at the human army with her voice enhanced by mana.

"Humans I will give one warning, go back to where you belong. If you continue to move towards our territory don't blame me for being ruthless!"

When the commanders of the human side heard Tsukiko's declaration they felt like they were being looked down upon. Their scouts had already told them that the demon army only consisted of ten thousand men, while they had fifty thousand. Was this woman trying to bluff her way to victory? Without heeding or caring about Tsukiko's warning the Sliral Kingdom's army continued onward.

Seeing that they didn't back down made Tsukiko smile even more. 'Well, it would've been rather boring if they gave up so easily. Now that they disregarded her warning she had no qualms destroying them.

Tsukiko gathered mana into the tip of her fingers and started reciting spell words. "Gentle breeze gather upon my call. Turn and turn and turn, until you grow. Into violent winds that flow. [Tornado]"

Tsukiko made spinning motions using her finger and from there a powerful tornado was made. It started moving fiercely towards the human army. The mages tried desperately to block the spell, but they could only delay it for a bit. A lot of knights at the front were massacred just like that.

'Now for another spell.' Tsukiko placed her hands onto the ground and started chanting spell words. "I call upon the mighty earth, bury my foes into your embrace. Show them thy love and fury. [Quake]"

The ground started shaking as the earth shattered in the middle of the human army. Some were lucky enough to escape while the others fell into the hole screaming and crying.

After being devastated by two spells the human army was in disarray. Some of those with weaker wills started to flee, but the moment they did so their commander ordered to kill them. "There is no turning back, those who flee from battle will be executed!"

When Tsukiko saw how easily the formation of the human army crumbled, she giggled. These humans had the audacity to try and invade their lands even though they were this weak.

'It's like a bunch of clowns came here to entertain me.' Tsukiko smiled as she started to chant her third spell.

"Icy frost that makes the bones tremble, the shivering cold that makes the soul quiver. Gather upon my call the frozen might of the eternal winter. [Cocytus]"

A large area in front of Tsukiko turned into a world of ice. Those that were near the spell turned into ice sculptures, those that were far enough were suffering frostbite. While the lucky ones who were at the back were feeling sluggish as the cold penetrated their skins.

...

Watching as their companions die one after another without them being able to do anything, most of the soldiers could no longer hold in their fear and fled the battlefield. It doesn't matter if they became deserters as long as they were alive, anything was fine as long as they were alive. Yet as they were about to flee en masse, they noticed that the demons had blocked their path of retreat.

While Tsukiko was unleashing her large scale spells, the demons under her used a secret path to get behind the human army. Seeing the demons in front wearing weak-looking equipment emboldened the frightened humans to attack them. Since the demons were blocking their path of retreat they needed to bypass the demons somehow.

While the deserters were trying their best to flee, the soldiers who haven't given up spotted Tsukiko. They immediately knew that she was the one who had unleashed those frightening spells. If they were able to take her down, they might be able to somehow win.

Knowing that most mages were weak in close quarters combat, the knights charged towards Tsukiko. Of course, as they charged towards her some of them were killed on the way, but as some of them got closer they felt that this nightmare was about to end.

A knight finally arrived in front of Tsukiko. He shouted at the former demon lord at the top of his lungs.

"Die Demon!" The Knight stabbed his sword towards Tsukiko's chest. Seeing as he successfully stabbed the demon in her heart the knight smiled. As he was feeling the joy of victory the knight saw that Tsukiko who was stabbed in the heart disappeared. It was nothing more than an illusion, the knight then heard someone whisper in his ear.

"Nice try little knight." Those were the last words the knight heard as he was stabbed by a spear of ice.
