If you watched Another then I think this should be a required episode to watch. It's a prequel of sorts but it's more than that, it's a look at why Misaki Mei is the way she is. This is a touching story and adds to the tragedy that is Another. It is impressive how one episode can add so much back story detail not only to the 12 episode series but Mei's character as well. If you watched Another, please watch this episode, preferably after.
