Intro
............
Ah— testing, testing. This is
Kiyomizu, in the former city of Kyoto.
Sending out a periodic signal. The current time is 1:21 PM, May 6, 2135 AD. This broadcast is coming to you from Base Camp Kiyomizu. Today's radiation level is 223.4 millisieverts. Please be advised that radiation levels may increase later today. Additionally, wolf-type mutants have been sighted in Fushimi. Please exercise extreme caution if you must go outside.
As the radio transmission plays, a pane of glass from a building in the ruined city falls away, caught by a cushion of overgrown vegetation and settling gently into the earth. Under a post-rain sky, a mutated ten-legged ant scuttles by. How peaceful it all is.
