...

'System, how did Raphael sense you?' Yami asked as he sat on her demon lord's throne.

*he is my big brother. is there something strange about that? He and I were close when father was around, but we went his own way.* the system said calmly.

*don't worry, host, they are not going to kill you just because you have me... they will kill you because you are a demon. The good old racism.* the system said calmly

'what about the end of the world thing?' She asked

*... there can not away be light. One day that will be swallowed by the darkness bringing an end to creation. The only way to stop this is for my little sis and me to work together, but...* the system went quiet.

'Does she really want to see this world come to an end?' Yami asked.

* I don't know.* the system said in a low voice as its voice disappeared.

'seems fun, system vs. system.' Yami thought as she looked at the time.

"Just 3 more days before I enter that world again. I wonder if I can face chaos... I should be able to." Yami said calmly as she looked at her points.

'5 million D Grade souls... S Grade skills are what I'm after.' She thought as she called for Anna.

"search for a world that is fast. Something like one year here is a thousand or so years in there after which go and conquer it." Yami said calmly.

"yes, master." She said as she went to search for one.

Soon 3 days past and Yami went on to enter the formation. She left everyone to go gather high-grade fruit for her.

On a battlefield, a kid with blonde hair was facing 10 demons all by himself.

The blonde hair kid walked up to someone that looked like him, and just as he was about to attack, everyone froze as they looked at a hole that appeared in space above them.

Yami slowly walked out as she looked around.

'I was Early.' She thought as her eyes fell on Meliodas, who was the golden-haired kid.

"Meliodas, for the crime of betraying demons and joining angels, you and your father will be judged before a demon king," Yami said calmly, but everyone around this planet heard her words.

Meliodas and the other 10 looked up with deep frowns, but the demon other demons took steps backward, letting Yami do her job.

Meliodas body began floating up towards her, after which Yami ripped open a space and grabbed his father that was sealed away.

Everyone was shocked at how easily Yami did this.

Yami licked her lips slightly as she looked at the female demons below. One of them was just standing there without any clothes.

"Why am I being judged?" Meliodas father said in anger and fear.

"haha, that I don't know, or do I care. Next time kill your son before this kind of stuff doesn't happen." Yami said as she knocked them out and threw them into the system storage.

"you 10 will be under my control until I leave," Yami said with her arms crossed.

"don't..." the guy that looked at Meliodas was about to say something, but his body exploded.

"I wasn't asking," Yami said calmly as she landed on the ground.

All of them took a step backward in shock and fear. Yami slowly removed her mask, showing her looks.

"I don't like repeating myself, alright?" Yami asked with a smile, to which they all nodded their head too.

"Good, now you 9 should take over this world. Don't kill all the humans or races. At least 500,000 should stay alive." Yami said as they all nodded.

"Before that, go regain your magical energy. You two can stay, as for you all take your time." Yami said as the two female demons started behind, but one of the males wanted to protect one of the females.

"do I need to repeat myself?" Yami asked with narrowed eyes. The woman pushes him away, trying to keep him from doing something stupid

'demons showing love? Seeing how they have a human appearance, they have special bloodlines.' Yami thought as she watched the male with no mouth fly off.

"what're your names," Yami asked as with a smile.

"Derieri," Derieri said calmly.

Derieri is a toned woman with long spiky orange hair. She wears no clothes, instead covering the breasts, left arm and right leg in her own darkness. She has demon markings on her left cheek which resemble a beast's open mouth with a circle in the center, she lost her left arm long ago.

"I'm Melascula," Melacula said calmly.

Melascula is a young woman with long, pink hair. She wears a sleeveless white leotard with horizontal and vertical lines in the middle and on top her breast. She is constantly cloaked in a shroud of her own darkness. 

"you two will be my right and left hand before the time I'm in this world. Let me give you two better curses," Yami said as she took their curses away and bit on their necks.

The two couldn't help but let out a small moan feeling Yami lips.

"what?" they grew confused as they felt their low parts feel strange.

Yami eyes glowed red, as she gave off an evil smile.
