You'd have to take care of most girls because they wouldn't survive in a world that doesn't provide them with huge paychecks for doing cute noises.
Haachama isn't in for the money and can provide food for herself. Her insanity might also infect you and it's probably better to be insane in the post-apocalypse.
It's only logical choice, really.
