Cycle Zero : reincarnated as the Demon King, Now What?

The Demon Lord Awakens

All the demons were saying, “Our lord has arrived. Our demon lord Diablo has been resurrected.”

Ren sat on the throne, trying to understand what was going on and what he was doing here. “Who the hell is Diablo?” he said to himself. Then, from the crowd of demons, Rias walked toward him and said, “Welcome, my king. We are here to do your bidding.” Ren was quiet for a few minutes. When Rias looked at him, she saw that Ren had already turned red, staring at her chest. Rias said, “Is that what you want? I am here to do your bidding.” Ren snapped back to reality and said, “Yes. I have been reborn, and I have come back to rule this realm.” The whole crowd of demons shouted in response. After the meeting, he told everyone to leave except Rias and said to her, “It’s been so long, I can’t remember much of what happened.” He lied to her.

Rias said, “My lord, you can just use your power to take all the information you want from me.” She said this genuinely. “Really, I can?” he screamed, then calmed himself immediately. “Oh yeah, that ability.”

Then a voice echoed in his head: “Do you want to use the unique skill Telepathy?” He said yes, then touched Rias on her head. Immediately, he saw everything that had happened. After a few seconds, he had everything he needed and told Rias to leave him alone, which she did.

So somehow I’ve been reborn into this so-called Diablo’s body. Well, for now, I guess I know what I’m dealing with and how to act.

That same day, while sitting on his throne, Rias came to him and said, “My lord, we’ve been attacked by the humans again, and they have killed some of our kind.” Ren, who now answered to Diablo, said, “I told you all not to engage at all costs before I died. Now I’m starting to regret saying that. I will handle it myself. I’ll show the world that I have awakened.” He left the chamber in rage. As he was leaving, Rias said, “No need to involve yourself with these humans. I alone can defeat them.”

They quickly got to where the attackers were. When he arrived, he saw about a thousand soldiers, including five hundred holy mages, five hundred enslaved dark elves, and three hundred summoned beasts. He laughed to himself, then flew up into the sky dramatically and said, “I am back, humans. This massacre of my kind shall end today.”

“Who is that? Who is that?” the humans asked among themselves. Then the oldest among them said, “This is Demon Lord Diablo. He was said to have been dead for decades. How is he here?” The leader who had led the armies into the demon realm said, “Attack!”

Just as they were about to attack, Diablo snapped his fingers and said, “Die.” A black aura of force surged toward the soldiers, and in an instant, all one thousand soldiers and five hundred mages were killed.

Then the voice in his head said, “Unique skill Instant Death has been used. You have successfully gained 5000 exp points from killing the humans.” He flew toward the dark elves and summoned beasts and said, “You are free.” He told Rias to take them to Malgorath, also known as the demon realm. Then he dissolved the alliance between the summoned beasts and the humans who had summoned them. “You are also my kind. You shall come with us to Malgorath.”
