Demon Lord's Reincarnation

After the battle with Evior, Kretos became rather famous in the school. Many students wanted to learn from him, and lower level teachers also wanted the same. This greatly annoyed Kretos, so he gave the task of teaching them to Afeus. If Afeus is able to teach the basics of mana control to the students, Kretos was willing to acknowledge him as his disciple and would teach him greater mana control. 

This motivated Afeus greatly as he guided the others in basic mana control. While everyone was going crazy regarding the discovery of spells that didn't need elementals, Kretos decided to rest. 

As he closed his eyes shut, Kretos immediately went to sleep. He would usually be only half asleep since enemies could attack him at any time and he needed to be ready, but this time he was in a deep sleep. As he was sleeping he had a dream, a very lucid dream. 

In the dream, he was fighting a strong opponent with horns of a goat, and a tail that was a snake. Its giant body was twice Kretos's size who was bigger than most. This otherworldly being held an axe taller than Kretos and it was thick as a tree. The goat demon swung his axe at Kretos who wanted to dodge but couldn't. He then raised his large sword to block the incoming attack. 

The difference in strength between Kretos and the goat demon was great so he was blown away. He hit the wall behind him and coughed up blood. Normally when this happens the person blown away would either be fearful or be in despair, yet it was the opposite for Kretos. He felt extremely excited that it was like a drug to him. He smiled viciously at the strong opponent before him and charged again. 

The goat demon was shocked that the attack he made didn't even slow Kretos down, instead, it actually made him even faster. Bleeding all over, Kretos was using his immense mana to keep his body together. The goat demon and Kretos were locking their weapons trying to gain the upper hand when the snake tail of the goat demon moved and bit Kretos on the neck. 

Kretos didn't even bother to dodge as he strengthened the muscles in his neck by gathering most of his mana in it. The snake tail was unable to penetrate Kretos's skin, this shocked the goat demon as he realized the problem. 

Though he was stronger than Kretos, and their mana supply was equal, but the goat demon's control over his mana was far lesser than Kretos. If that's the case he needed to capitalize on his own advantage. The goat demon roared as he gathered his strength and pushed Kretos aside. 

Once Kretos was off balance the goat demon charged at Kretos with his horns. Kretos was unable to block it using his sword nor was he able to block it using his mana. The horn penetrated his body. But due to a demon's greater life force, this wasn't enough to kill him. 

Kretos who was losing so badly wasn't afraid instead he was ecstatic as he started laughing heartily. Hearing him laugh the goat demon thought Kretos had gone crazy in fear. As the goat demon thought of that he felt something hit his chin, the goat demon whose horns were stuck on Kretos's chest were broken off. 

Kretos had kneed the goat demon's chin with everything he had. The goat demon flew from across the room falling on the floor, it then started roaring in pain. On the other hand, Kretos was laughing merrily as he pulled out the horns of the goat demon from his body. Blood splattered everywhere, as his wound slowly closed. 

"This is awesome! As expected of one of the subordinates of the Demon Empress! Come then bring me some more joy as we dance between life and death!" Hearing what Kretos said, the goat demon who lay on the floor finally understood that Kretos was indeed crazy, but not the type of crazy he was expecting. 

Kretos waited for the goat demon to get up, and once he saw the goat demon was up and about Kretos charged at him. The goat demon swung his axe to intercept Kretos, who then blurred as he was about to be hit. 

"Doing the same thing again? That's not what I want!" The goat demon raised his axe as he heard Kretos's voice from above, he then felt something stabbed at him at the back. He saw that Kretos's sword had gone through his body. The goat demon then immediately turned around and swung his axe wildly. Kretos pulled out his sword and backed away. 

Kretos then attacked but this time due to the goat demon's wound its reaction time was slower and was once again hit by Kretos. As Kretos backed away he looked disappointed. "This is getting rather boring... How about I do this to make it interesting again!" 

Kretos then slowly approached the goat demon and once he stood in front of the goat demon his vicious smile grew wider. Kretos then provoked the goat demon into attacking. The goat demon swung its axe at full power, but this time Kretos was able to fling it away using his sword. Once the axe was gone kretos threw away his weapon as well, and the two began brawling. 

Punches and kicks were exchanged as blood flew around the room. The sound of pounding flesh and Kretos's hearty laugh could be heard echoing in the great large room. After hours of attacking each other, the goat demon finally fell to the ground as Kretos proceeded to smash the goat demon's head repeatedly. As the goat demon's consciousness was fading he heard his opponent's last words to him. 

"Thank you for the battle." 

...

After Kretos was done pounding at the goat demon he picked up his sword and proceeded to the next room. The last room of this castle he was invading was the throne room. In it was a single person sitting on a luxurious throne. The person on the throne was emitting mana that could crush the very soul of a weaker demon, but to Kretos it just got him even more excited.

The one on the throne was a beautiful demon wearing a rather revealing red dress. She looked at Kretos while yawning, she was about to say something when Kretos spoke first. Kretos lifted his sword and pointed it at the demoness and with his vicious smile spoke. 

"Demon Empress, let's fight!"
