Zero Two (ゼロツー)

Zero Two (ゼロツー, Zero Tsū) is the main heroine and the deuteragonist of DARLING in the FRANXX. She is a human-klaxo Sapien hybrid and a member of the APE Special Forces, primarily fighting on the front lines.

Zero Two's personality is rumored to be dangerous, cold, and alluring as she grew up. Her outlook on life is quite cynical, so she didn't bother with a name since they are all meant to fight and die.

When people around her fail, she hardly bats an eye at it because, to her, it is just a fact of life that everyone dies. Zero Two always keeps people at arm's length with mocking humor, nihilism, and emotional detachment. Zero Two also freely talks about how much she hates society.

It is later seen that Zero Two is a very unruly, passionate, fierce-tempered, self-confident, smug, assertive, and carefree girl who hates to follow the rules set up by the adults.

She did not receive the same regular training as other children in the Garden to become a Parasite. She was trapped in her room for so long that she described it as being kept inside forever.

When Hiro witnessed Zero Two's suffering several times during her training, he made up his mind to rescue her. When Hiro came to save her, Zero Two had just gone through testing and was curled up on the floor. Hiro shattered her window with a searchlight, and although Zero Two was initially aggressive, she was moved by Hiro's tears and began crawling towards his outstretched hand.

The two went outside and started to run away. However, Hiro's attempt to run away with Zero Two failed. Both of them got sent to their rooms, and the two never see each other again.

Since Zero Two's meeting with Hiro did leave a significant impression on her, she swore since that day to become human since if she were like him, they could always be together. To make her even more determined, people also convinced her into thinking that she could become human by killing Klaxosaurs by Papa and the others.
