Rikka and Suou relationship improvements

Rikka and Suou relationship has developed so much since the first game. I remember how I was very near to hate her for all the blackmailing she tried to do to bind Suou to her permanently while distancing or even damaging Mayuri's life. After accepting the situation she smoothed out to be a much more nice girl (even though I still don't like her as much as the other heroines). Here they really look like Amitie, friends that share the current step in their life together.

On unrelated note, seems like the story still has the same "ghost story" element that we've seen prominent in the first game. Erika went through quite an interesting story about a "mysterious red rope" seen in an hospital (that turned out to be blood). It's quite a standard story told in these settings, but it was interesting to see Rikka frightened by it. I wonder if the actual mystery case around Mayuri has actually a "ghost story" element too.
