Looks like a funny J&R game but still looks like a weird idea for Umineko IMO. Well Doujin games.....
Found another cool Opening "Parody" MAD (which I think has been posted before). This time its a recreating of the style of the CANAAN Intro in Umineko context.

Really nice use of existing footage and editing. Must have been quite some work.
I'm surprised nobody put it on YT yet as MAD of this OP aren't that rare and the song really rocks.
