Demon Lord's Reincarnation

Kretos was feeling a bit bored as he was waiting for numerous things to happen. He was waiting for his sword to be made, he was waiting for the tournament to happen, and he was waiting for his memories to return. All he was doing was waiting and that was starting to infuriate him. 

'Hmm, should I just leave this place and go around the land? Surely if I travel all over the place, someone would recognize me. Maybe I can even find someone strong enough to satisfy my thirst for battle... Though, I am quite interested in fighting those elves in the tournament... Hmmm, I guess I'll stick around until the tournament's over.' 

After making his decision Kretos sat crossed leg on the corner of his room trying to condense the mana flowing through him. He couldn't remember much, but he knew that his current self was rather weak, well in comparison to the person in his memories. 

Aside from his mana being weaker and less pure, his current body was actually quite strong than the one in his memories. The body of the person in his memories didn't need to train his body for it was already powerful from the start. Yet his current body seems to be toned from hard work. 

'I have memories of someone with the same name, but with a different body. That person in my dreams was clearly not human. I, on the other hand, seem to be one hundred percent human. I wonder what that means?... Was I not human at some point, or were the dreams just some grand delusion of mine?' 

As Kretos started to wonder about his true origins he felt a wave of different mana fluctuations. The level and density of the mana fluctuations were obviously not from the students. This kind of density were from bigger fish.

'Has the master of the rats finally arrived? That was rather quick.' Kretos stood from his position and regulated his breathing. 

'I hope these guys would prove to be an actual challenge.'

...

Walganus and his troops arrived grandly in front of the school gates. The guards in the capital didn't bother to stop the march since it wasn't unusual for the top four mages to bring their soldiers in a show of force. As long as they don't go near the palace the army nor the guards would deal with them. 

In fact, some of the guards went close to watch the show. Seeing as the third strongest mage in the kingdom was about to do something, it would naturally be an exciting spectacle to witness. 

....

"Lord Walganus, how can I help you today?" One of the teachers approached. Walganus looked at the smiling teacher and spoke in an ice-cold tone. 

"Bring me the one who killed my grandson." Hearing Walganus's demand the teacher frowned. Of course, he knew who the person who killed Evior was. Kretos was currently the hottest topic in the school, and everyone in school knows of him and what he did. It was obvious what Walganus wanted to do with Kretos, but the teacher still needed to confirm it. 

"May I ask why you are looking for him?" 

"Hmph, of course, I'm here to kill him." The moment those words were said the teacher frowned. 

"Both parties have consented on that duel, their life and death were decided by their own skills." 

"I do not care, if you won't give me the child then moved aside. If you don't move I will kill you as well." 

"Lord Walganus, I might not be your match, but even for you and your family fighting the full might of Rulwarry would force you to pay a heavy price." 

"Enough chatter move aside or die!" The teacher was about to say something when someone spoke first. 

"I heard some fools have come looking for me, are you those fools?" Walganus spotted the person who spoke and immediately attacked with an [ice spear]. Unlike other ice spears, this one was larger and thicker than most. It flew towards the rude person's direction but instead of piercing him, the rude person caught the ice spear and thew it back killing a few of Walganus's men.

"So you really are some fools that came to kill me. Come then, let's see if you're worthy enough for a proper battle." Walganus and Sagar looked at Kretos who was cockily waiting for them to make a move. 

"So you're the one who killed my grandson. It seems like you do have some ability." Walganus raised his arm and a wooden staff appeared. He then tapped his staff onto the ground and a magic circle was formed. 

"A teleportation spell." Right before everyone's eyes the army from the Osted family and Kretos disappeared.

....

Walganus and his group alongside Kretos were teleported into an open field. Kretos looked around and then shrugged his shoulders. 

"Is this the grave you have chosen?" 

"Hmph, this is the grave I have chosen for you," Walganus answered with a sneer on his face. The true reason he teleported everyone here was because it would be hard to battle in the capital with its excessive spell barriers. Here in the open plains, a mage can really show his abilities. 

"Let's see whose grave this will be!" Kretos showed his vicious smile as he provoked his enemies. 

"Kill him!" Hearing Walganus's orders the men of the Osted family launched a series of spells at Kretos. Seeing the incoming spells Kretos raised his right hand and created a mana barrier. To everyone's surprise, Kretos's mana barrier was able to block all the incoming spells with relative ease. 

Kretos then formed a ball of mana and shot it at the enemy's side. "[Wall of Gaia] [Castle of Stone]." Walganus and Sagar immediately used their strongest defensive spells. A huge wall of earth and a fortress of stone appeared to block the incoming ball of mana. 

Upon contact with the wall of earth, the ball of mana pierced through it, but when it hit the walls of stone it was only able to pass through some layers but was unable to fully pierce through. Seeing this scene stunned Kretos for a moment but then the smile on his face grew even wider. 

Kretos coated his body with mana, charged forth, and punched the wall of stone making it crumble. The moment the stone wall crumbled another barrage of spells came raining down on Kretos but this time instead of blocking he evaded them. 

"[Increase weight x10]" Walganus used another spell which made the gravity around Kretos heavier. Yet despite his body becoming so heavy that the ground he stood on was sinking, Kretos was still able to dodge most of the spells that came down on him. He was nicked every now and then but that just made him even more excited. 

As he was dodging the spells he noticed that the Osted family changed formation. He was now in the middle of a circle formation. The guys that surrounded him looked like warriors, holding their swords, spears, and shields.

Then there were the mages at the side chanting a rather lengthy spell. It seems like they were about to use a joint spell. So the warriors surrounding Kretos were used to buy some time, while the mages prepare a sure kill spell. Seeing that the situation looked a bit dire for him just made Kretos happier. 

"Now this is a battle!"
