• Portal — yes Land of the Lustrous is a Japanese manga series written and illustrated by Haruko Ichikawa (manga artist). It was serialized in Kodansha's seinen manga magazine Monthly Afternoon from October 2012 to April 2024, with its chapters collected in thirteen tankōbon volumes. Set in a world inhabited by Lustrous—immortal humanoid lifeforms who are the embodiments of gemstones—it chronicles their efforts to find the place where they belong while fighting to defend themselves against the celestial humanoid race known as the Lunarians. A 3D anime television series adaptation by Orange aired between October and December 2017.

Land of the Lustrous is set in a far, distant future where the Earth had been struck six times by meteorites, ravaging it in the process. All of the remaining land was reduced to a single coast, and nearly all life was destroyed. Over vast periods, a new race of sentient lifeforms emerged: immortal humanoids embodied by gemstones known as the Lustrous. Phosphophyllite (Phos) is weak (with one of the lowest hardnesses) and considered useless by their peers since they are too brittle to fight. Phos asks their aloof but wise colleague Cinnabar for help after they receive an assignment to create a natural history encyclopedia, thus beginning their friendship and personal growth. Meanwhile, the twenty-eight Lustrous led by their master, Kongo, are fighting to defend themselves against a celestial humanoid race called the Lunarians (Moon people), who inhabit the Moon and invade Earth every few days to take advantage of their luxury value while seeking to harvest the Lustrous' bodies for decorations.

• Phosphophyllite: • Known as "Phos" for short. One of the weaker gems, having a hardness of 3.5. Declared as too weak for battle, Phos is tasked with creating an encyclopedia logging new information. Despite this, as well as their immaturity and clumsiness, Phosphophyllite desires to enter the battlefield in order to be acknowledged by their peers and prove their worth. As Phos keeps experiencing hardships in battle, their limbs, along with their memories, are gradually lost and replaced with other minerals. At the same time, their personality and perspective begin to change gradually with each replacement. • Cinnabar: • An aloof but wise gem that is even weaker than Phos, with a hardness of 2. They exude a powerful poison in their body. However, because this poison taints the environment and erases memories stored inside affected gem shards, Cinnabar is kept on night watch, although they yearn to escape. • Diamond: • A kind-hearted gem who has the maximum hardness of 10, but is still fragile against enemy attacks. • Bort: • An intimidating diamond-class gem who is powerful in combat and is the most durable of the gems.
