Higurashi really bewildered me with this one. I've never seen such an interesting take on a mystery where you play the same A flip of the perspective on the same chapter where the same events occur, but that said perspective makes everything new.

Instead of Keiichi or Akasaka, we are introduced to Shion who I felt needed more character and I was glad to be able to read in the eyes of her; she was an even more fun and energetic addition to the bubbly cast of Higurashi. We get to see that Shion struggles with her position as a sister without the demon's mark of the Sonozaki line, and suffers by Oryou's decisions to isolate her from the family--literally picking favorites for tradition. For a social butterfly, the struggles start to form and she feels lonely, trying to shrug it off from what she truly feels.
Her interactions are great too, I really liked the dynamic of Satoshi and Shion. With Shion crushing on him, as she learns that he is gone combined with the information about the murders and "demoning away" in Hinamizawa, she starts to go crazy and the twists and turn unravel itself with the dramatic plot.
I really liked this one just as much as the others for not only getting me to question more about the mystery as a whole and who the culprit is, but its unique way of introducing me that said mystery.
