Amagami SS+ Plus Episode 13 was released today. With this episode we have the beginning of the Mia arc (Junichi's sister). Not really sure what to expect here, I'm typically not a fan of any sort of brother-sisterly love but we'll see how this plays out. Now that I remember it, this may actually be a fan service episode, without any actual relationship between the two siblings.

She is not entirely unattractive.

I am most excited for where this episode leads and it seems to be quite mysterious (same with the ending of the original Amagami SS). Only thing we can do is watch the episode to find out!
