There are plenty of recommendations already I can vouch for so instead of repeating them I’ll mention Land of the Lustrous. Don’t be fooled by the CGI, this is the anime that convinced me that CGI in anime often being bad is a budget/animation issue and it can look absolutely stunning when done well. It’s a story about Phosphophyllite, or Phos as she is known to friends, a young and very fragile Gem who dreams of helping her friends in the war effort against the Lunarians and her journey of self-discovery. Sadly the anime does not wrap up the whole story so you would have to read the manga to see the end (the manga is finished!) but it’s still a great watch, the animation adds a lot to the story.
