Just finished watching the dvd versions of Hagurishi 1st season and I have to say...ohhh GOD the blood and gore. LOL
Well orignally my favorite and still up to now is Rikka, but due to Shion's great character (MAN DID I REALLY SAID THAT?!! After she killed lotsa people? O_o) development, I kinda liked her better than Rikka. Another reason is that Rikka is too loli for me Iam gonna go with Shion since she's a bit more womanly :P
Especially now that with her new character designs and images with the 5 original characters makes her a great addition, not just a plot character behind her sister.
I love horror/suspense/thriller/gory/mystery movies and Hagurishi is one of best anime that gave that feel.
