9'δ

9'δ is a character in DARLING in the FRANXX. She was a Parasite who served in the 9's, a special forces unit that APE directly controls. She was partnered with 9'ε and piloted a FRANXX called the 9 Model. Delta has short, light green hair and eyes of the same color. She wears the standard 9’s uniform, colored white and gold. She is the shortest in stature of all the Nines (with her leader Alpha being a close second, followed by Zeta and her identical pistils all tied for third). Delta is shown to be cheerful and mischievous, and curious. When not in combat, Delta is quite inquisitive, felinely sneaking her way around Mistillteinn after the members of Squad 13 had already gone to bed (with the notable exception of Kokoro), as shown in episode 17. When in combat, however, Delta is shown to be very smug, scoffing the klaxosaur battalions of Gran Crevasse as being "boring," although she did admit that "there's no end to them." Of course, all that smugness of hers came to a horrible end when their 9 Model FranXX was decapitated. Despite her lack of sentimentality and indifference, she is shown to be fearful of death, as she cried out she didn’t want to die as VIRM soldiers crushed her 9 Model to pieces. In the manga, she retains her cheerfulness and is eager to please. She also acts arrogant when in combat but she mellows out after a battle with the Klaxosaur Princess leaves her comatose and she is saved by Squad 13 from being pruned by APE. She feels in debt to the squad for their kindness and offers to help them in battle, although she still has an, albeit amicable, superior complex towards them.
