It is thirty years after the failure of the Space Colonization Program. Humanity is nearly extinct. A perpetual and deadly Rain falls on the Earth. Men known as "Junkers" plunder goods and artifacts from the ruins of civilization. One such Junker sneaks alone into the most dangerous of all ruins—a "Sarcophagus City." In the center of this dead city, he discovers a pre-War planetarium. And as he enters he is greeted by Hoshino Yumemi, a companion robot. Without a single shred of doubt, she assumes he is the first customer she's had in 30 years. She attempts to show him the stars at once, but the planetarium projector is broken. Unable to make heads or tails of her conversation, he ends up agreeing to try and repair the projector...

After nearly a decade of reading and watching Key's works, and now having finished Planetarian's unlikely adaptation, I think I have come to accept that Key does not appeal much to me anymore. I have aged and moved on since those times, as has the anime industry and its community, and no longer feel all too impressed by what their stories had to offer.

At the same time, I recognise that not everybody began watching anime at the same time. Some people have only just gotten into the medium in recent months, and so they may not yet be acquainted with Key's works. For these read more

There's something truly memorizing about the idea of a post apocalyptic world. Perhaps its the perpetual loneliness of a race on the brink of extinction or how survivors struggle to cope with reality by clinging onto past memories. Whatever the case, Planetarian embodies my favorite scenario in anime by telling a tragic tale between the most unlikely of companions in a world that has left them behind.

The story revolves around a hard nosed militaristic man and an adorable AI unit named Yumemi who functions as a tour guide of a Planetarium . She has zero awareness of the world on the verge of collapse read more

"Planetarian is an one in many futuristic possibilities of our world."

Humanity is almost extinct due to some type of biological attack 30 years ago. Out of the people left some are called "Junkers", who scavenge for foods and goods from the destroyed cities to survive. Now one such "Junker" Kuzuya is searching for supplies in one such ruined city called Sarcophagus City, escaping from some bots he enter into an old military facility where he meets a robot who has been on sleep for almost 30 years.

Based on the visual novel made by Key, a Planetarian adaptation is what fans have been dreamed for years. It’s been far too long but now, it’s a reality. With that out of the way, fans should anticipate and expect this to be a neat clean series that isn’t too short or long to take all in. Taking place in a dystopian world nearly 30 years after the failure of the Space Colonization Program, Planetarian’s storytelling is pretty simple. Humanity is mostly gone and the main protagonist (a Junker, someone who scavenges for useful goods) seeks refuge at an abandoned planetarium. It’s there that he read more
