Today everyone was getting ready to go to Rad after eating breakfast. All they were doing was waiting for Satan who was still getting ready.

Mammon : usually it's one of us who is late but him?"

Beel : is he sick?"

MC : yesterday he was quiet maybe he is?"

Lucifer : one of you go check on h-!?

Suddenly someone walked downstairs and everyone froze in shock not sure what to think and extremely confused.

Walking downstairs and standing in front of them was a woman in a rad uniform but she looked like Satan but also identical to Lillth.

MC : ..... Satan?"

Satan : yes?"

MC : ....what happened to you?....."

Satan : oh? That isn't important. "

Asmo : .....honey.... have you look in a mirror recently?"

Satan : yes? How did you think I fix the uniform? Anyway aren't we going to be late?"

After this Satan just walked away leaving and once he left Mammon said.

Mammon : ..... we're all thinking the same thing right!?"

Beel : he....I....he looked exactly like her....."

Belphie : but how?"

MC : like who?"

Mammon : it seems pretty obvious who he looks like...."

MC: I d-Oh....you mean Lillth?"

Asmo : it was like.... like looking at a ghost....it was scary...."

Levi : why....why does he look like her?"

MC: .... guys you know how he feels about being compared to Lucifer now your saying this? He probably mess up a spell he was doing in one of his books like last time. and doesn't want to acknowledge this for this very reason."

Asmo : right....still it's scary how identical he is to her...."

Mammon : Lucifer you ok?"

Lucifer : ....y....we should go we're going to be late"

And with that Lucifer left not even acknowledging the situation.

Later at Rad Satan went on with her day as did everyone else everyone did look at her confused confusing Satan for a new student until MC had to walk with them and tell everyone that it was Satan.

And her brothers  barley said anything to her the entire day but Lucifer just ignored her completely and everyone knew why.

Anyway at the end of the day Satan managed to catch up with Lucifer who was walking home earlier than everyone else and said.

Lucifer : it's funny you can't stand the sight of me now. I barely changed anything at all. But I guess now that I look basically like her you can't face me"

Lucifer stop in his tracks and said facing Satan completely shock at what she said.

Lucifer: .....you did this to yourself on purpose to look like her?...."

Satan: yeah? I mean you did most of the work. You got what you wanted? You wanted Lillth back so badly that you made me as identical as you could to her.
I only finished what you started."

Lucifer: ....why are you doing this!?"

Satan : so now that you have what you want? you suddenly feel bad now? "

Lucifer: you think I wanted this!?"

Satan: it's what everyone always wanted? Especially you. If not then you wouldn't have made me like her. "

Lucifer: ..... your doing this to just get back at me? For something I didn't mean to do!?"

Satan : oh you meant it Lucifer! And you never wanted me to know. That's why all the memories I have of her from you her face is always blurry.

I was never anything. I was just a replacement. To fill in a void. You started this and I ended it."

Lucifer: ....WHAT YOUR DOING IS SICK AND TWISTED EVEN FOR YOU!!"

Satan : so? You think I care? I always wondered what meaning did I have to life? Why I am here? and I finally found out what that is. It's not my fault that you realize what you did was sick and twisted to little to late."

Lucifer : YOU CAN'T DO THIS!"

Satan : this is permanent. Like I said you wanted this. You got it so now you and everyone else are going to live with it. "

Lucifer : .....what is wrong with you....."

Satan : what's wrong with brother? Why did you want this so badly?"

After this Satan walked away. And Lucifer didn't know what to do. there wasn't much he could do. He just couldn't understand why Satan would do something like this.

He didn't want this he would never want this. But could some of what Satan said he true?

Did he unknowingly try to make Satan to look like Lillth?. He wasn't sure what to think. But wondered what cause Satan to break now? Out of everything why now?"

Later at the house Lucifer decided to tell everyone about why Satan was doing this and nobody could believe it except Mammon.

Mammon : I....i never thought Satan would do something like this but can you blame them for thinking that?"

Lucifer : ....but it's not true!"

Mammon : maybe you did it subconsciously did it. But Satan doesn't see it like that "

Lucifer : ....."

Levi : yesterday wasn't he going through the attic for some old books?"

Belphie : he mentioned his memories of her from you were blurry. What if he saw pictures of her?. Remember Simeon drop off some photos albums from celestial? And left them in the attic "

Asmo : we saw those pictures there's nothing off with th....but to him there would be?"

MC : if he already assumed this. seeing how similar they were to her probably really set Satan off"

Lucifer : still....it doesn't make sense. Doing this out of revenge for something I didn't mean to do? What does Satan hope to achieve with this?"

MC : probably just to traumatize you guys with it figuring they don't have anything else to do.

Satan is probably going through an encoded identity crisis and figuring if that's what you wanted subconsciously then that must be their only true identity" 

Lucifer : how do we fix this?"

MC : this is something you guys are going to have to fix I don't have any answers. All I can do is talk with them"
