How To Be A Demon lord: The Former Hero's Journey As A Demon Lord!

"Now I get it. I was going about it all wrong. I wasn't doing it properly. I now understand that out of all of you, I was the greatest fool,"

Rosavellt's hand tightened around her sword and she could only grit her teeth in anger! There was a flash of lightning that illuminated the sky and the army in front of her started to shift around nervously.

Rosavellt thought about how she had been showing her disgusting side to the demon lord all this time and she couldn't help but laugh. She put her hand to her head and she just laughed! I must've looked like a fool in front of my lord! I just couldn't see past my own stupidity.

So this is what the demon lord was trying to tell me all this time. He could see the truth long before I even opened my eyes. How can he see all these things so vividly? How was he able to predict all these things so easily?

It doesn't matter how much I try to spare them. It doesn't matter how many times I show them mercy. A fool will always be a fool and my people can only be what they are. I've been blind all this time.

"But I won't be a fool anymore. Kill a hundred to save a thousand. Kill a thousand to save a million. That is what the demon lord once told me and I will take his advice into account. Since you cannot learn from my mercy, then I will make sure you learn through pain. I will kill all of you. Every person in front of me is going to die and I will enjoy it. Let it be a lesson to the rest of my people. We are servants of the demon lord and there will be no form of mutiny while I am alive,"

Once Rosavellt made this declaration, se felt like a giant dam that has been holding her back all this time was finally opened. There was no longer anything holding her back. Rosavellt put her sword forward and she finally activated her Resonance.

[Magic Resonance: Queen of The Damned]

A great amount of Mana started to build around Rosavellt. The mana was colored black and it was even visible to the naked eyes as smoke. The mana rose into the sky and everyone watched in shock as the mana started to take the form of a woman. Before even a minute passed, an armored woman with black skin and white hair had formed out of the mana. She had a permanent smile plastered on her face and her hair was long enough to even cover her eyes. If you looked closely enough, you will see that she didn't have any eyes, instead, she had black holes like a skeleton. There was a long black scythe in her hands that Rosavellt could control in any way she wanted.

As Rosavellt rose her hand up, the woman also rose her scythe. This was Rosavellt's magic resonance. The [Queen of the Damned] was a projection of Rosavellt's magic and she could control it in any way she wanted with only her mind.

Rosavellt was a member of the undead royal family and all her family members had resonances that were connected to death. But unlike Reginald that could summon hundreds of skeletons and use them to fight, Rosavellt could only summon one avatar, but this avatar was far stronger than the hundreds of skeletons that her brother could summon. Reginald's magic resonance was only at F-class because he forced himself to achieve it even though he was not ready, but Rosavellt was in a perfect state of mind! She had more than enough power to control the magic resonance. This allowed her Resonance to jump into the C-class immediately!

From a cliff, overlooking the valley below, Kronos and two other members of the council of the underworld stood with wide eyes as he watched what was happening. Kronos was one of the people that watched Dulla grow up and he never thought a day would come when she would have a smile on her face as she gets ready to kill her own people! She was laughing like it didn't even matter to her! Kronos had to stop her!

Kronos planned all of this himself to make sure he got rid of Dulla, but it would be bad for the underworld to lose these many soldiers at once. There are five hundred soldiers down there and if Rosavellt kills all of them, our fighting force will be affected. I have to stop her.

Kronos immediately made his way down to the ground with the two other members of the council that came with him. Kronos called the other members of the council because he wanted to have some extra help in case there was a problem that needed them to fight, and Kronos also wanted to use this opportunity to show the council just how much Dulla messed up. Kronos might pretend to support Dulla on the outside, but he secretly loved the fact that she messed this up so much. At least now there won't be anyone stopping him from taking the throne.

But even though he was happy that Dulla was now in trouble, he wasn't going to allow Rosavellt to kill these many soldiers. The three of them landed in the space between Rosavellt and the undead army. The army of undead were all cowering at the sight of the female giant that appeared from Rosavellt's Resonance. None of the army members have ever seen a Resonance before and so they were terrified by the advanced magic. They were only A-class and so the Magic Resonance from an SSS-class was too much for any of them to withstand.

Once Kronos showed up in front of Rosavellt, he expected her to calm down so that they could speak, but her cold look never died down. Kronos now understood why all of the soldiers were cowering so much. Her eyes were terrifyingly cold! It was like she wasn't even looking at him. It was the kind of look that someone would give a cockroach on the wall before stepping on it!

"Rosavellt, wait! Let's talk about this. This isn't what you need to do right now! Don't punish all of them for something that Dulla did. She is the one that made them attack the demon towns -"

"Get out of my way,"

Rosavellt said this coldly and the giant woman behind her started to raise her scythe. Kronos' eyes widened! He always knew that Rosavellt had a soft spot for the undead so he thought she would listen once he started to plead for the men, but she was not stopping for anything! Why is she so adamant to kill them!?

"I have made up my mind. It doesn't matter who the person is. Anyone that is willing to go against my lord will die. I will spare you, Kronos, because you didn't take part in the attacks. But everyone here will die. This will be a lesson to all of you,"

Rosavellt started to walk forward and Kronos had to immediately stand in her way. He felt the pressure from her bloodlust slam into him and he stood his ground. Kronos was an Elite-class. He knew that it would be hard to fight Rosavellt since her magic Resonance was very strong, but he had help from the council members behind him. The three of them can handle this easily. There is no way Rosavellt can win against three Elite-class fighters on her own.

Kronos was already preparing to stop her if he needed to and the other two council members that came with him were also preparing to attack, but a portal suddenly opened beside Rosavellt and two people walked out. Dragonnel and Alucard stood at Rosavellt's sides. Alucard had his hands behind his back and Dragonnel folded his hand across his chest as he grinned at the undead. Kronos thought they were here to try to stop Rosavellt, but Alucard only spoke to Rosavellt.

"I suppose I owe you an apology. You are not a complete fool after all. I'm glad you didn't bring shame to the demon lord,"

Rosavellt felt pain in her chest as she remembered her stupidity from before. She should have learned what the demon lord was trying to teach her without all of this drama. The demon lord should not have had to do all of this just to teach a mere slave how to behave. I am truly ashamed.

Dragonnel slapped her on the shoulder with a wider grin.

"Your remorse is clear for all to see, there is no need to beat yourself up about it. Just make sure you do not bring the demon lord any more shame,"

Kronos' eyes widened once he heard what Alucard and Dragonnel were saying!! They were telling her to go ahead with her plan!? Why!?

"Alucard! What are you trying to do here!? Are you trying to make her kill them!?"

"Shut up and move out of her way,"

Alucard gave Kronos an impassive look and Kronos took a step back as Alucard's eyes turned blood red. Alucard's voice echoed in the silent valley.

"Look at me, Kronos. Take a very good look at who you are about to fight. Do you believe, that if you were to fight against me, you would walk out of here with your life?"

Kronos' heart sped up drastically! He could feel the blood in his body speeding up and his heart rate was increasing madly! He knew that Alucard's words weren't a mere threat! It was true. Kronos would not survive against someone like Alucard. And even if Kronos got help from the two council members behind him, the three of them could not take on Alucard, Dragonnel, and Rosavellt together. They would surely be killed.

So these are the heads of the demon lord's household?
