Higurashi When They Cry: Abducted by Demons Arc, Vol. 1

Life couldn't be better for Keiichi Maebara. Sure, he's moved to a
sleepy, little town where nothing happens and high school consists of a
one-room schoolhouse - but his new friends and fellow students are all
cute girls! When he happens upon a story about a grisly local murder,
however, his contentment turns to uneasiness as he finds himself drawn
into a web of silent intrigue that involves his newfound friends...and
threatens his very existence.
