An official website for Houseki no Kuni has opened and announced that the manga by Haruko Ichikawa will get a TV anime for Fall 2017.

Synopsis
In the distant future, a new immortal and genderless life form called Gems populate the Earth. The 28 Gems must fight against the Moon Dwellers, who attack them regularly to abduct them and to turn them into decorations. Each Gem is assigned a role, such as a fighter or a medic.

Being only 300 years old, Phosphophyllite is the youngest of the Gems and has no assignment yet. He wants to help to fight the Moon Dwellers, but is too weak and brittle for battle. One day the master of Gems, Adamantine, assigns him the task of creating a natural history encyclopedia. (Source: MU)
