Re: Episode 4
Well, that episode worked well, not only to bring Haruka back to school but also to mark the changing point for Hiyori's character. I know some people will think she got off too easily for all that she did, but I'm always willing to give people a second chance if they've genuinely changed, and that does seem to be the case for Hiyori.
On the other hand, I think the show went a bit too far with Grandpa's perversions. Hopefully he won't come up much more in the rest of the series...
