Chapter 6

Hi everyone! How has your day been? Thank you all for the reads!

Bold: Thoughts

hi: Mindscape talking

3rd person POV

Before Y/N fell asleep on the chair, he thought that Rias would be desperate because her wedding is coming up soon. So, he decided to use the reality to cast an illusion that they were all in deep sleep. Meanwhile he continued to sleep on the chair. Just then, a red portal came out from the ground and Rias came out.

Rias: I'm going to make you pay for what you did. After I use you guys for the rating game, I am going to kill you guys slowly.. one by one... In the name of Rias Gremory-----

Y/N threw a sword that cut off Rias hand. She clutched it and scream in pain. The illusion disappeared and Y/N was behind her with DSD on her neck 

Y/N: Seems like one lesson wasn't enough bimbo. Would you like another one or the Gremory clan extinct. Choose wisely, I do not have the patience to tolerate anymore of your bullshit. 

Rias: HOW DARE---- 

Another portal came out and Grayfia appeared. What she saw nearly gave her a heart attack. 

Grayfia: Rias what are you doing! You want our family extinct! Lord Y/N please release her, I will bring her back and tell this to Sirzechs 

Y/N: Lord? Never mind we will talk about this another time. 

Y/N shoved Rias towards Grayfia and pointed the DSD towards the both of them. 

Y/N: Anymore funny business and the Gremory is gone from the books. Get out. 

Nodding in reply, Grayfia quickly teleported herself and Rias back to the underworld. 

Back in the underworld

Rias and Grayfia stepped out of the portal Sirzechs was at the study room reading up documents. He titled up his head and saw the panic in Grayfia's face

Sirzechs: Ria-tan, Grayfia where were you both? Grayfia you ok? 

Grayfia: Love, Rias nearly got us killed. She wanted to turn Y/N and his girls into her peerage. Luckily I got there in time to prevent this from happening. 

Sirzechs (panic): YOU WHAT!! Rias are you crazy!! I hope he isn't angry.

Rias: What's so important about him! I need to get off this wedding and you aren't helping! 

Sirzechs: Ria-tan, I need to explain to you who Y/N is. 

Small timeskip

After explaining to Rias, she was still adamant about getting Y/N into her peerage 

Rias: I need to get out this wedding, I don't want to marry Riser! 

All Sirzechs could do at this point in time is sigh. 

Sirzechs: Rias don't be unreasonable. To be honest, you had all these years to train your own peerage and decided not to. The red dragon emperor is only a bonus, trying to get Y/N into your peerage is making it worse. All the devils will be extinct if you do not think twice. 

Rias: But---

Sirzechs: No more but's Rias! Get out I need some peace.

Grayfia: *sigh* I hope she doesn't create more mess. You want a massage?
