Teisei Nenki Maitreya

Tokyo, the year 2000. Middle schooler Fujio Komaki has slowly begun seeing images of the collapse of the earth and hearing a strange "voice" inside his head. That's when a man calling himself only "a friend" appears before him. Nostradamus predicted the end of the world (July 1999) -- what exists beyond it...!? An end of the century legend!
