Midnight Channel Synopsis

I figured before people begin to be a fan about a story they never have heard about before, they should at least have a general idea of what this story is about. It's as such that I bring you the synopsis.

Synopsis:

A sixteen year old Keiji Sanada has just transferred from a no-name town in a small prefecture of Japan to the large city of Osaka in order to live with his uncle, Hideo Yamada and his daughter, Ayumi. He then begins his time at Temujin High School as a second-year student. After befriending three fellow students in his class, he learns about a mysterious channel that is said to only play at Midnight when the moon is full. During this time, the person who's face is shown during the channel is said to disappear from the face of the earth. As the four friends test the rumor, disappearances of famous and normal people alike began to happen around them. Is it a coincidence? Or is this Midnight Channel really the cause to all of the cases? It is up to Keiji and his friends to find out before the entire city of Osaka is erased from the world. However, their investigation will not only lead to whether or not the Midnight Channel causes the disappearances, but dives much deeper into the causes of the disappearances, leading to a horrifying truth to be revealed to the four investigators...

What is the Midnight Channel, and what does it have to do with all of these cases? There's only one way to find out...
