Higurashi - Abducted by Demons Arc, tome 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.
