Endless darkness is all I could see, I wonder if something went wrong? (*No host, you are still waiting to be born.*) A mechanical voice said.
("Oh okay. You are the system, right?") (*Yes host, I'm here to help with anything you need.*) ("Can I name you or do you have a name?") (*I have no name, so host can call me whatever you want.*) ("Okay from now on your name is Sera, okay?") (*Yes host, that's fine.*) ("Sera can I skip the whole baby thing or do I have to go though that?") (*I can seal your mind until an age you can move of your own volition.*) ("Yes do that and I'll speak to you when I get back.") (*Yes host, I'll seal your mind now, see you soon.*)
*5 Years later.
(*Host wake up.*) I open my eyes and look around the massive room with crimson walls and a bed so big I can't see the end. ("I'm up Sera, so what happened while I was out? And why is your voice more human?") (*Well your name is Scarlet now, you are the younger identical twin of Rias and have been spoiled by your older brother Sirzechs. And the reason I have a human voice is thanks to you naming me.*)
("Oh so you voice reflects the name you're given that's good to know. And Sirzechs is a sis-con then. At least that's the same, what about my relationship with Rias?") (*Well you and Her are close, did you want me to merge your memories?*) ("You can can do that? Then yes that would be a lot easier.") (*Ok starting memory merge, this my sting a bit.*)
A lot of random images start poring into my mind. Sorting through the memories, I start to make a plan. ("Hey Sera, when do I get my evil pieces?") I ask, thinking what kind of servants I want. (*You get them at age 9*) [A/N: I couldn't find the actual age online, so, sorry if it's wrong.] ("So I have four years to train. Sera can you make me a training regime for the next four years.")
I have to be as strong as I can get for the future especially since me being here changes things. (*Yes Scarlet, I'll get started on that now. Why don't you go check out your new home for the time being.*) Okay, so I left my room to try and find the training room. (*You know, if you just focus on training then what's the point in being here?*) Sera said and she's right what's the point in being strong if I have no one to protect, so let's go and be a child, and just train a little bit.
*4 Years later.
"Rias hurry up or we'll be late." I shout running ahead. "Calm down Scarlet, big brother won't leave without us." She said panting trying to keep up.
I just sigh at her. "Why don't you train with me, so you can build up some more stamina." I said. I'm sure she wasn't this bad in the anime. "High class devil's don't need to train. You are just an anomaly." Rias states with confidence. "Then what about our cousin, he has more intense training than me and he is a high class devil." I retort, running up to Sirzechs.
"Big brother do you think I'm strange because I train?" I ask with puppy dog eyes. "Of course not, you're my darling little sister, how could you be strange." Sirzechs said patting my head, and I turn to Rias and say "See big brother doesn't think it's strange." I say while sticking out my tongue. "That's because big brother is strange too." She said matter of factly.
I just ignore her and hurry to the train, I'm so excited to finally get my evil pieces and start trying to find my peerage. After a long journey to Sirzechs territory, waiting for the preparations finish. "Rias do you think you'll get a mutation piece?" I asked.
"I don't think so since it's very rare, even Sirzechs only got one." She replied. "I bet you get one." I said knowing she does get one. Finally we are in front of the statue. "So who goes first?" I asked, I'm pretty sure it's going to be Rias. "Rias, step forward and touch the statue to become a registered king." I watch as Rias walks up to the statue and places her hand on it as it glows bright and fourteen crimson chess pieces.
"Oh you have a mutation piece, congratulations Rias." Dad said with a big smile. "Next, Scarlet step up and touch the statue." As I make my way up to the statue, I start thinking about where I should go to find members for my peerage. Standing in front of the statue with a massive smile, I place my hand on it, as the bright light started to dim, I looked my evil pieces in stunned silence. "They are all mutation pieces, that has never happened before!" Everyone was silent as I took my pieces. And then I heard Sirzechs say "That's my little sisters for you, congratulations to both Rias and Scarlet."
