Season 3 can be entitled "Higurashi no
Naku Koro ni?
Nano desu!" (yes, the red "na"'s are included) and it will feature club activity batsu game mishaps (mostly by Keiichi being the loser and taking the punishment), some totally crazy and laugh-out-loud-inducing scenes, with some attempt at rom-com.
Now if that reminded you of that infamous FMP season, raise your hand.
That would definitely send the Higurashi saga down the drain.
