Demon Lord's Reincarnation

Kretos felt like he could finally let loose against these opponents, as he started to circulate his mana faster than ever before. He felt his heart thumping as he hit another person in front of him. Each one came at him with the sole intent of buying time, it didn't matter if they died today, for if they achieve victory against the monster before them their families that they will leave behind would be compensated. On the other hand, if they lose everything ends. 

...

While Kretos was having fun with his battle against the Osted family, Amon who was getting a bit bored noticed the commotion that was happening in the city. He quickly went out to gather information on what happened. 

...

Sagar who was witnessing the unbelievable capabilities of the boy before him looked at his father. There was a crazed look in Walganus's face, this was not normal. Sagar knew that his father doted on Evior very much but not to this extent. 

Seeing the capabilities of the boy called Kretos, Walganus would've normally retreated at this point to conduct a better plan. Everything from the start seems a bit weird and too fast-paced. 

'Now that I think about it, even I wasn't thinking straight, I let my anger control me...' Sagar was finally realizing that something was wrong. The more powerful the mage, the better his mental and emotional fortitude was, but this time both Sagar and Walganus allowed their emotions to guide their actions. 

'Is this a mental attack on us amplifying our aggressive thoughts and feelings? If so, then why does it seem that only father and I are the only ones affected.' 

Sagar remembered the gathering before they came to attack, none of those present had the same crazed eyes as his father... 'Wait, the stronger members of the family seem to have acted a little bit more aggressive than usual. It's just a tiny change so disregarded it. Even the Grand Mage had become excessively aggressive lately.'

Sagar was slowly realizing a hidden truth, he wanted to say something to his father but by the looks of it, Walganus wasn't going to listen. 

'Still, I have to try...'

"Father how about we calm down for a bit and regroup." Walganus who was casting numerous supporting spells looked at his only son and frowned. 

"What are you saying, Sagar? Are you telling me to flee?! Are you saying that the whole force of the Osted family cannot match up to a single child?!" 

"That's not what I meant father. I'm just saying-"

"ENOUGH! I don't need your excuses, from this day forth I no longer have a son. Begone from my sight!" Sagar no longer retorted and bowed his head before he left. 

As he was leaving his signaled some of his men. When they saw Sagar's signal the men slowly backed away from the battlefield. 

'As I expected my father is no longer of sound mind. He has been corrupted by something. Good thing it doesn't seem like he has been fully consumed by rage, else who would've killed me on the spot. I better lay low afterward and investigate what's truly happening.' 

Sagar looked at Walganus and saluted him. "May victory smile upon you, father." 'But if you fail, do not worry I will make sure the Osted Family will come back more powerful than before.' 

Sagar and his men then quietly left the battlefield. 

...

Kretos who was almost finished killing off all the warriors finally felt like the mages were done chanting their spell. He looked above and as expected the spell was near completion. A huge ball of multicolored light was floating above the battleground. 

Kretos couldn't help but smile as he saw the sight before him. He knew instinctively that the thing above was something that could actually kill him. Yet instead of feeling any dread, Kretos felt elated. 

"COME ON THEN, SHOW ME EVERTYHING YOU GOT!" A huge beam of light fell upon Kretos who was able to evade at the last second. The beam of light was so fast that Kretos's senses couldn't keep up. It was a good thing his instincts and reflex were good enough for him to be able to dodge. 

Yet despite dodging Kretos arm was still hit. Even though he coated himself with his mana, and had several defensive layers on him he was still hurt by that beam of light. 

Kretos couldn't help but laugh in excitement. Another beam of light came falling down on him, but this time he didn't dodge. Kretos gathered mana into his fist and punched the beam of light. Walganus and the other members of the Osted Family were shocked by the sight. That was the ultimate spell of the Osted Family and it was deflected by his bare fists.

"Do not falter! He cannot keep doing that, end it with a barrage." Walganus shouted at the others. The ball of light above then started shooting multiple beams of light towards Kretos. He laughed in a crazed manner as he kept on punching each beam of light that came his way. 

After punching a dozen beams of light Kretos's hands were scorched. On the other hand, due to the excessive mana needed to maintain the spell a lot the mages of the Osted family have fainted or died. It was now a war of attrition, either Kretos burns to death or the Osted family runs out of mana. 

Seeing this scene Walganus increased the output of the spell. Many of the mages fell immediately once the output increased, but this time Kretos was nearly unable to punch the approaching beam of light. As the output of mana increased the spell became faster and more powerful.

Kretos's left hand could no longer move and his right hand was nearing its limit as well. Seeing that Walganus thought he had won, but then Kretos used his legs. It was much harder than using his fists to redirect the attack but it was still possible. 

Walganus wanted to increase the mana output even more but then he realized he was the only one left standing. The mana being drained from him by the spell was enormous. He had a choice to make either stop using the spell or go all out into one last burst. Walganus immediately chose the latter. 

The strongest beam of light descended onto Kretos who smiled viciously and then headbutted the thing. The beam of light was once again redirected, seeing the ridiculous scene Walganus had no words. As he was losing consciousness mana exhaustion he heard Kretos's voice. 

"That was pretty fun." 

...

After the battle ended Kretos was about to leave when he suddenly heard someone clapping. He quickly looked behind and saw a man standing at a distance. Kretos was able to quickly assess that the man was pretty strong by the way he carried himself. 

"This day must be my birthday or something, giving me one present after another." Kretos smile grew even more vicious as he knew that the man before him wasn't here just to congratulate him on his victory. He looked at his scorched arms, then at his slightly scorched legs, and he checked his mana which was at half capacity. Kretos then mumbled to himself. 

"Still, good to go."
