Places someone might find the character? Things they might be doing? Sectors 3 and 4 in general. The beach, the shelter, the convenience store, the memorial gardens, the library, the pet cafe, and a couple of other places. She enjoys learning (especially self-help books), visiting the pets at the cafe and bringing them treats, visiting friends, tending her garden, and just trying to have a good time of it in Marina.
Is the character in any IC group, including the school? Details! She's part of the Defense Force and an Exoricst of the Black Order (who's Innocence Time Record has the ability to stop and rewind time or reverse it, but only temporarily). And she's part of the Welcoming Committee.
What kind of person does the character get along with? She has trouble getting along with people who are generally cruel and mean, but other than that, Miranda tries to find good in everyone.
Is there any type of CR you feel the character is missing (e.g. romantic interests, mentor figures, etc)? Romantic interests would be amusing, but I don't know how probable that would be. More girl friends! She knows so many guys. Maybe a training partner who would be a good match to use Time Record against.
