Demon Lord's Reincarnation

In a room inside the mansion of the Regalcrags, a group of people had gathered. The atmosphere was heavy as the people from the village described what had happened. Valdel was seething with rage as he listened to the villagers' story. Lara, on the other hand, was emitting bloodlust that made the people shudder in fear. The two were obviously angry and their rage was not something just anyone could handle. 

Yet the people present weren't that worried about the two, what was important was the person sitting quietly at the back. Ren was simply listening with his eyes closed. He wasn't saying anything, he wasn't even emitting that overwhelming pressure he usually has. He wasn't reacting at all which made the whole experience even scarier for those who knew what kind of monster he was. 

While everyone's attention was on how Ren would react, Lara and Valdel could no longer hold it in and were about to charge outside. It was at that moment, without even seeing him move from his spot Ren made both of his childhood friends faint. 

Though no one saw him move and all everyone saw was Lara and Valdel fainting, everyone present knew that Ren must've done something. This caused everyone to tremble slightly, now that the two people that could stop him were unconscious those present grew even more fearful.

They were now expecting an outburst of rage and sorrow from Ren. But instead, they were surprised to see Ren looking ever so calm. This just made everyone even more nervous. 

"Bring them to their rooms." After saying that one line Ren left the room. 

...

Ren headed towards the room were his mother and little brother were staying in. When he got to the room, his mother Milly was still asleep. On the other hand, his little brother Kurt was crying very hard while being carried by one of the maids in the mansion.

Despite the noise, Milly continued to sleep. The trauma of what happened had taken a great toll on her. Seeing his human mother turn into that, Ren could feel a torrent of emotions swirling within him.

Ren observed the two for a bit more and then spoke to Silika via their mental link. 

'Silika I want you to stay here and guard them.' 

'As you wish.' After hearing Silika's response Ren disappeared from her sight. The moment Ren was gone Silika dropped down to her knees and started to gasp for air. She who had existed for a very long time was now feeling a long-forgotten emotion, she was feeling actual fear. 

She was assaulted by Ren's multiple emotions swirling within him. Since she and he were linked through the soul, she felt it the darkness deep within. 

...

Harold who was still pissed by the verdict given to him by his peers was drinking in his shop. As he was about to take another sip, somebody suddenly entered and grasped his neck. Harold tried to free himself from the one who was gripping him when suddenly he felt an immense feeling of dread come over him. He finally saw who was gripping his neck, it was none other than the person he believes to be his ancestor, Ren.

"Who are you?! Release my lord at once!" Oliver who entered the room to serve Harold some snacks saw his master being assaulted. Without thinking much about it Oliver quickly moved to attack but he then found himself unable to move. 

...

"*Cough* My esteemed *cough* Ancestor... To what do I owe the pleasure?" Even though he was being strangled by Ren, Harold remained respectful. 

"One of your compatriots a demon wearing a maid uniform attacked the village I used to live in. Tell me who she is and why she attacked the village." It was easy for Ren to deduce that Harold had something to do with this since the villagers had some mana residue that had an inkling of demonic origin. 

"She's Krystal, one *cough* of the demons with great power that came out with me. She must've attacked the village either because it was planned, or she got bored." 

"So there are more of your ilk prancing around?" Ren tightened his grip which made Harold's face pale even more. 

Harold wanted to answer but he was chocking harder than he thought. He simply made some whizzing sounds. When Ren saw Harold's reaction he loosened his grip a bit. 

"Tell me, where they're hiding." 

"The last I heard was they were in the mage's tower of the supposed Grand Mage of the Serbek Kingdom."  When Ren heard the answer he wanted to hear he let go of Harold. 

"Are you not going to ask what we are planning to do?" Ren who was about to leave heard Harold's question and looked back. 

"What's the use in asking such a thing, if all your companions are dead." Harold shivered in both fear and awe of Ren. He didn't even bother to say going to die, he simply stated that Harold's companions were already dead. 

"Are you not going to kill me?" This time Ren didn't respond to Harold's question and left. When Ren's presence could no longer be felt, Oliver was finally able to move. 

"Are you alright my lord?" 

"I'm alive at least," Harold answered indifferently. He then looked at the direction of where the mage's tower was and smiled a bit. 

'You fools, now you're going to learn the truth, but the price to pay will be your lives.' 

...

Ren who started running at full speed was now heading to Carto village. Unlike before it only took him a few hours to reach Carto village. Upon nearing the village he smelled the familiar scent of blood. He saw the bodies of adventurers and villagers scattered about, and as he continued running he saw the body of a very familiar person. The body no longer had any head to distinguish who it was, but Ren knew immediately the body that lay before him was that of his father. 

He felt his heart aching as he gently picked up the body and started walking towards the village. As he was near the entrance of the village, he saw the head of his father and beside it was the body of his friend. Lisa was there laying on the ground bruised and full of wounds but even with all that, she had a smile on her face. 

He approached Lisa's dead body and knelt. He closed Lisa's eyes and whispered something in her ear. After that, he took the head of his father and aligned it with his dead body. Ren then started to gather the bodies of all the dead villagers and adventurers. Once he was done he used an earth spell to create holes on the ground in which he placed all the dead bodies, except his father's. 

Ren looked at the body of his dead father and bowed his head. "Thank you for everything." Ren then proceeded to burn his father's body. As the smoke of the burning body rose up to the sky, a single tear fell from Ren's cheek as he spoke. 

"Dead upon the field of glory, Hero fit for song and story. I will remember you for all eternity."
