Olivia Morningstar as you can probably already tell from her last name- she is Lucifer Morningstar's daughter. Olivia has the power of the multiverse, she could travel to any universe to wherever and whenever she want. So while her father was helping the LAPD she joined the avengers where she found the love of her life and they got married- that love being James Barnes. Right now, surprisingly there were no missions and the avengers had some time off. So Olivia and the avengers decided they want to be semi normal for a little while and "try a different universe" they bought themselves a house (using Tony's money of course) and just lived.
