Let's look at the similar plots of these films:
Phos and Cinnabar (first image) have similar story roles to Jake and Neytiri from Avatar (second image):
While Avatar is a sci-fi space story, and Land of the Lustrous is a fantasy adventure anime, both take place on an alien planet with different species.
The stories begin similarly:
- In Avatar Jake is a newcomer to Pandora and meets the alien Neytiri. She doesn't seem to get along with Jake at first, but later on they become lovers.
- In Land of the Lustrous Phosphophyllite or Phos meets a fellow Gem named Cinnabar, a toxic humanoid that releases mercury. Cinnabar still doesn't get along with Phos until now, but in the rest of the episodes, Phos and Cinnabar are somehow getting along in a respectful manner.
They have similar endings:
- In Avatar, Neytiri saved Jake from Col. Quaritch and puts a gas mask on Jakes's face, allowing him to breathe properly again.
- In Land of the Lustrous, Cinnabar flooded the whole Lunarians and beheaded the last Lunarian that was attempting to stop Phos.
So is Phos based on Jake, and Cinnabar based on Neytiri?
Are they coincidentally similar? Avatar came out in 2009 and Land of the Lustrous was released in 2017-2018. While they have different directors and authors, the stories of these films are somehow similar.
