Mars

Mars is a secondary character in Heaven Will Be Mine, and is affiliated with Cradle's Graces. She "[messes] up a lot, but [she says] sorry a lot, and [she means] it."

Personality
Mars is incredibly concerned about the future of humanity (or at least, she happens to talk about this more than the other characters). She frequently expresses concern about how her actions might be affecting them and is very concerned about doing the right thing. Amidst her doubts about her own actions, she seems to have more faith in Cradle's Graces than Pluto.

Her relationship with Pluto is caring, even as they tease each other. Their earliest described interactions took place while Pluto was still in training, where Mars assumed the role of mentor for some of the younger potential pilots. Before a number of her missions, Mars tries to convince Pluto to be more cautious, or even to let her accompany her as backup She also reassures Pluto in one of the chat logs that it isn't her fault that the space colonization program was ended.

According to Pluto, she has a history of intense and regrettable relationships with girls. One of these relationships was with Luna-Terra, and Mars is still angry about it.

Background
She is a second-generation pilot loyal to Cradle's Graces. At some point before the events of the game, Mars attempted to resign from Cradle's Graces, citing that she wanted to return to Earth. Nix refused her reservation on the grounds that she wouldn't have gone to space in the first place if she really wanted to go back.

Trivia

 * The bandage on Mars' nose in her flight communications with Pluto is from a fist fight with a member of the Cradle's Graces flight crew.
 * According to a Tweet posted on the Worst Girls Games Twitter, Mars' concept is that of a "classic hero pilot," and she is regarded by the developers as being the central hero of the conflict. This is further implied by Europa, who states that Mars might win the space war single-handedly, and that "she does nothing but cry and complain and win effortlessly, like a real hero." Worst Girls also remarks that Pluto's route is, in part, "about being the hero's mysterious psychic gf."
