I've been thinking about 8th sibling! Reader a lot. Probably an unhealthy amount.
Here are my thoughts on this.
Note: Reader, and MC are Two different people. This is an AU that I spiraled into after too many fanfics. Reader is suggested to be AFAB with She/her pronouns. I am not a writer.
So…
˖᯽ ݁˖ 8th Sibling reader! was closest to Lilith before the fall, with them being the youngest.
˖᯽ ݁˖ Reader had watched Lilith curiosity and love for humanity form in its beginning stages, and soon lead to her death.
˖᯽ ݁˖ Reader who also fought in the Celestial war, and fallen with her brothers. Who still has scars that just wont fade despite her new demonic body,
˖᯽ ݁˖ Reader, who's name was nearly forgotten during the first year post-fall. Being the only sister they had left, the brothers "accidentally" called her Lilith multiple times.
˖᯽ ݁˖ If they called MC Lilith post lesson 16, I headcanon they would do the same thing to Reader during the first year or more after they had fallen. It would lead to more tension, and Reader spiraling. Struggling with their already shambled identity and guilt.
˖᯽ ݁˖ GUILT- girly would feel SO MUCH of it along with the twins. This guilt would lead to some sort of complex, possibly similar to Levi's. Reader would feel that they aren't deserving of good things. I feel as though she would learn to cope over the many many years in The Devildom. However it will always linger, She would make most of her progress with MC.
˖᯽ ݁˖ After some centuries, I think she would cope. Some habits better than others. Slow progress. There would always be some lingering things though, like very self critical thoughts, and nightmares.
˖᯽ ݁˖ Reader would do things such as go sleep with Cerberus, or the twins during bad nights. She would go to Cerberus with treats and a blanket 5 out of 7 times, though. Since she doesn't like Belphie going in her mind (to help stop the nightmares) very much. And Beel already deals with his own, she wouldn't want to add more to that!
˖᯽ ݁˖ Now with MC, reader would make the most progress. Possibly go to like 2-3 therapy sessions (after heavy insistence). Open up a little more during a family discussion /meeting.
˖᯽ ݁˖ When it comes to MC, I'd like to think Reader would be more hesitant to make a pact. Possibly be the last to make one before Lucifer, or just not make one at all. Out of fear of losing yet another person in her life, especially since MC is a mortal/human.

These were a little angsty. I want to further develop this idea. Exploring more chaotic/fun dynamics reader has with the others.
Anyways. This was a long, garbage pile of words that probably don't make much sense to anyone else but my silly mind.
