I Woke Up as a Treasure to All the Races

[The original idea had been sitting around for years, and I've run out of inspiration, so I've changed it. Feel free to remove it from your favorites if that's an issue.] Have you heard of the females in beastman stories, the male insects in insectoid stories, the dragon clan's long-awaited offspring, or the new life of the machine race? If you haven't, that's fine. Now you have. After waking up one day, XX finds themself a ghost in another world. Their System explains that to become human again, they have to raise the happiness of all the world's races. A ghost without even a body is supposed to raise the happiness of every race? Is this some kind of joke? Then the System brings out a character creation card they can customize... P.S. The character card options are one female, one male, one variable, and one without a gender. Theme: The soul is more precious than one's identity.
