Darling in the Franxx is my
personal favorite anime, but the ending is very depressing and made me very
sad. As it is described: "The survivors of a catastrophic war against monsters cluster inside
mobile fortress cities and train youngsters to defend humanity by piloting large battle robots called Franxx." The characters in the show are called "parasites" since they were made and developed in a lab. The characters in the show also go by codes/codenames since names are no longer needed in this "timeline" that they are in. The "main characters"/the parasites from Plantation 13 go by: Codename: 002 (or Zero
Two), Codename: 016 (or Hiro), Codename: 015 (or Ichigo), Codename:
666 (or Zorome), Codename: 556 (or Kokoro), Codename: 214 (or Futoshi), Codename: 056 (or Goro), Codename: 390 (or Miku), Codename: 326 (or Mitsuru), Codename: 196 (or Ikuno).
