Reborn as Elizabeth Liones

I had just finished watching season 4(well season 3 really season 2 were just filler episodes)of my favourite anime seven deadly sins/nanatsu no taizai, as I went to bed I realized I left my chastiefol plush in the lounge, as I went down the staircase I tripped on one of my posters that had fallen of the wall earlier that day, and fell down the stairs and broke my neck. Next thing I know I'm being picked up by Meliodas from the dead arms of the latest reincarnation of Elizabeths mom.

What will happen to Rin in her new life as Elizabeth with the memories pf the 3000 year old curse, knowing this will she stop the demon king and the great deity and save Brittania and the seven deadly sins?
