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

That night, as Floid was trying to get some sleep, he suddenly opened a single eye and looked at the ceiling in surprise as a sudden wave of Mana washed over him. He frowned as he looked around. What was that? That has to be at least SSS-class Mana. There is no way that there is someone like that in this kingdom and I wouldn't sense them.

What Floid felt was not a person at all. He didn't know it, but the mana he felt was the mana that Priscilla used in Uta when they tried to summon a hero. The amount of Mana they used in summoning the hero was so great that it sent out a pulse of potent Mana that washed over the entire continent, anyone that was above SS-class would feel the mana. It was that pulse that Floid felt. Floid stayed still as he waited to see if there would be another pulse. He was sure that if this was a person, they would send out another pulse. But there was nothing after a long time already passed, so he relaxed again with a hum. What the hell was that?

Floid wondered what caused that pulse, but he knew that he was not the only one that felt it. It was probably felt by everyone above SS-class. But

since it already died down then he wouldn't be able to track it now. Floid was sure that Alucard was already looking into it. since Floid was already awake, he thought about his plan and how to start. If Floid's plan worked out the way he wanted, then that means everything would be fine and nothing would happen to Rosavellt. She would even come out stronger than before, but for his plan to work, that means that Rosavellt has to do something that would be very difficult for her.

Floid wasn't a fool, he always knew that Rosavellt wasn't completely loyal to him. Her loyalty was split down the middle and it belonged to both him and the Undead. She was serving him just as much as she was trying to save her people.

Call him selfish, but Floid hated it. He hated the fact that one of his servants was not completely loyal to him. Floid was a demon lord and this part of him amplifies all of his desires. Possessiveness, lust, hatred, sadism. All of his natural emotions and desires were amplified by his race and Floid felt an immense irritation inside him whenever he thinks that Rosavellt was not completely his. Floid wanted to own every single part of her. Floid still respected her resolve as a person and he knew that she wouldn't betray him, but that wasn't enough. It was never going to be enough.

....

"Do you really not understand what the demon lord is trying to tell you?"

Alucard suddenly said this to Rosavellt as the two of them were walking away from the demon lord's office the next day. They were just in a meeting with Floid where they learned that there was an attack on a small demon village near the eastern part of Aradite by the undead. The village was pillaged and more than a hundred demons were killed. The remaining demons were forced to run away and take refuge in another town before they would be killed as well. Floid was able to see all of these things happen through the familiars that Alucard sent out and he called Alucard and Rosavellt once he was done watching it.

Floid told them that they had to prepare for the next attacks. Floid out Alucard in charge of battle formations and preparing a plan of attack while Rosavellt would be the one leading the army that would take care of the undead. Even though they were talking about her own people, Rosavellt was still very professional in the meeting. She gladly accepted her mission and once they were excused, she and Alucard walked out together. It was after they had gone all the way to the other part of the castle that Alucard finally spoke up.

Once he said what he said, Rosavellt looked at him with clear confusion. Rosavellt couldn't understand what Alucard was trying to tell her! Ever since they had that meeting with Dulla, Rosavellt has noticed that Alucard was disappointed in her for some reason. She tried to figure out what could have made him disappointed but she just couldn't!

"What? What do you mean? What is the demon lord trying to tell me?"

Alucard was stunned. This has to be the first time in his life that he was thinking Rosavellt was an idiot! Don't tell me she is really this blind! Alucard thought that Rosavellt was smarter than this. He thought that she would be able to understand the demon lord's words even without him having to say them. But it seems that Rosavellt was still blinded by her love for her family! Rosavellt still loved the undead just as much as she loved the demon lord and Alucard knew that he is not the one that will help Rosavellt to realize what the Demon lord wants to tell her! This is something that Rosavellt had to figure out on her own!

"If you do not understand then that is that. You can only be what you are, after all. I will have the battle formation prepared by sundown. Make sure the troops are ready by then,"

Alucard only said this before he walked away and Rosavellt watched him go with curiosity. What was the demon lord trying to tell her? Was there a problem with her services? No, I am sure the demon lord would not hide my inadequacies from me. He would tell me if I was doing something wrong and I would never make such a mistake again. Did something happen during the meeting?

Rosavellt shook her head and turned around as she made her way to the barracks to gather her troops. She was very interested in what Alucard said, but she must first carry out the demon lord's orders. She will think about it later.

After Rosavellt got her armor, she went to the barracks and gathered a small troop of five thousand. She told all of them to gear up and she was about to lead them out of the barracks when Alucard suddenly walked out of a portal in front of her. Rosavellt knew that he was here to give her the battle plan. Alucard was a very efficient person and he was already done making the entire plan in under two hours. Rosavellt knew that she wouldn't have made a battle plan this quickly. She started reading through the plan and she was stunned. It was an elaborate and straightforward plan and Rosavellt knew it would work perfectly.

But then her eyes landed on something at the bottom of the paper and they widened in surprise. She looked up at Alucard with a questioning gaze.

"Is this real? Are you sure?"

"The demon lord himself gave me the orders. Even though you don't understand the meaning behind it, it's still a plan that our master made and it must be obeyed,"

Rosavellt was shocked by the confirmation! This plan was not what she had expected! She didn't think that the main focus of their plan would be containment instead of eradication! The demon lord told Alucard to make a plan that would avoid killing as many Undead as possible! Floid's orders were to prevent the death of any more demons while also ensuring that they didn't kill many Undead. Rosavellt looked at the plan for a long time in shock before she spoke up again.

"I understand the plan, but why is this the plan? It makes no sense. Is the demon lord being... merciful?"

Rosavellt was quick to explain that she didn't know what sort of plan this was! Why is the demon lord showing mercy to the undead!? Is the demon lord trying to be merciful because of her? Was he doing this because they are her people? That makes no sense. Rosavellt knew that Floid was not the sort of person to be merciful no matter who it was. Floid killed Reginald without mercy so why was he suddenly becoming merciful now?

Alucard spoke up with a frown.

"You have to figure that out on your own. It is not my place to relay what the demon lord is thinking and it is not the demon lord's job to explain every minor detail of his plan to those below him. But I hope you find out that your naivety is what caused this outcome. After all of this is done, make sure you apologize to our master, or else I will be the one you have to answer to next. For the demon lord to go to such an extent to explain something so simple to the head maid of his castle... how detestable."

Alucard stopped here and took in a silent breath. The annoyance he was feeling was too great and he didn't think he could stay in front of Rosavellt anymore so he just turned and started walking away. Alucard wouldn't say anything more because he knew that Rosavellt was supposed to figure this out on her own. The demon lord would not be happy if Alucard reveals everything like this so Alucard would allow Rosavellt to figure it out herself.
