Synopsis

One year after a suddenly-appeared virus annihilated the humans, three high school girls, Koharu, Natsuki, and Chiaki became ghosts and played around their school. During these days, plants vigorously grew on the Earth. It seemed that something had happened because of the virus. This is the slice-of-life “supernatural” comedy of high school girls playing around in the post-apocalypse world.
