The Enigma of Amigara Fault

""This hole...! It was made for me!""

A short horror manga by Junji Ito, located in the back of the second volume of his fish-zombie-apocalypse book Gyo. A boy (Owaki) and a girl (Yoshida) meet on Amigara Mountain, where an unsettling discovery has been made. Human shaped holes are scattered across the mountain, and it soon becomes clear that the holes are "calling" to the people they are shaped like. So what happens when they enter the hole? Well, you can be sure that massive amounts of Claustrophobia and Nightmare Fuel are involved. Can be read here.

Should it seriously disturb you, counter with liberal application of this comic, or this one, or this one, or this one., or possibly even this one, this one, or this one. There's also a dramatic reading.

 * Token Romance: It was really unnecessary for Owaki and Yoshida to get together. It happened so that we'd get a giant Hope Spot, before things get worse.
