Minami is a little ghost girl who appeared in episode 2, she may or may not make another appearance one day but I think appearances of her will be less frequent than most characters

Minami is a sad little ghost girl who's meant to invoke a sense of pity in the audience, out of all the characters who've been in this so far she probably had the most emotional impact.

If you are the type to do your own audio editing feel free to try any special ghosty effects you want alongside a basic reading of the lines with your normal voice
