The fic is a reader-insert fic placing the reader in the role of Code 059, a Parasite who joins Squad 13 alongside Zero Two and his partner Code 067/Kyu, and follows the story of the anime, with some noticeable differences due to Code 059's presence.
NOTE: As this fic follows the plot of the anime itself, all spoilers related to the anime's story will be unmarked. Therefore, it's probably best if you watch the anime first before continuing to scroll down. You Have Been Warned!
Darling in the FranXX: Homecoming provides examples of:
- Audience Surrogate: Code 059. As a reader-insert, he's usually addressed by either his code number or "(Y/N)".
- Experienced Protagonist: Code 059 and Kyu have been Parasites for over a year by the time they arrive at Squad 13, with 059 having been the leader of their previous squad.
- Girls Love Stuffed Animals: Kyu has a teddy bear she calls Mr. Snuggles, which she has kept since her childhood in the Garden.
- Mercy Kill: In the first chapter, 059 finds the same wounded bird Hiro passed when he met Zero Two, and seeing its condition and how it most likely won't fly again, snaps its neck to put it out of its misery.
- Number Two: In the fourth chapter, Code 059 is promoted to Ichigo's second-in-command.
- What the Hell, Hero?: In chapter 17, Code 059 furiously lambasts Ichigo for her selfish actions in splitting Hiro and Zero Two apart and getting the latter kicked out of Squad 13, knowing she's just using any claims of Zero Two being a monster and a danger to the team as an excuse to give her the best chance at getting Hiro.
