With "The War" over and only a few thousand people left, a constantly falling rain, which is potentially deadly due to years and years of nuclear fallout, threatens to destroy the rest. The protagonist of the story is a scavenger who has broken into an abandoned city. He takes refuge from the rain inside a large department store building and finds something very unexpected on the top floor...

Planetarian is a "kinetic novel", or a linear, non-interactive visual novella, running on Key's RealLive engine, that will take about 4 or 5 hours to read. Upon completion, options appear on the main menu allowing you to view the CGs again and listen to the music.

In response to the 2011 Tohoku Earthquake, the game's PSP publisher Prototype released a special version of Planetarian at a reduced price from which all profits would be donated to the Japan Red Cross. Over 16,000 copies were sold, and together Prototype and Visual Art's donated over 22 million yen (about $290,000 USD) to relief efforts.
