Miranda Lotto
I think I finally settled on two different ideas for where I could go with Miranda and hopefully I can decide between the two of them soon.
Dark!Miranda: She isn't going to necessarily be evil, but Miranda is from a world where the Order is actually the ones out to ruin the world, but lying to people and the Noah are the ones trying to save it! She's be a bit more hardened, indoctrinated into the Order's ideology, but eager to please and not as willing to directly harm people. Because the Order is only trying to "save" mankind, but building up an army and seeking out Innocence and Accomodators to use it. The Noah are the true villains stealing souls to make monsters! (Actually the souls agree to become weapons to save those they love still left behind, whereas the Order is using "Innocence" to destroy said souls that they fight and using their energy for power.)
Mutant!Miranda: She's an AU I made a long time ago where Miranda's a mutant whose abilities kicked in and accidentally locked her village into a time loop for 100+ years. The Order is a mutant-focused branch of the Church that keeps itself under wraps, and uses mutants to fight against the Noah and Akuma. It was set in 2005. Her powers were the same as her Innocence's, with an addition of her being able to borrow time from others, but that's not something she ever did intentionally. It was just how she survived in the time loop and stayed young.
