I feel Truck-kun treats boys better than girls in general. Girls very often end up in the role of a villainess doomed to a lousy end, even death, unless they somehow manage to change things with no fancy powers. Guys often find themselves in far more neutral roles, or even in a position of a hero, with fancy powers to boot. Although there is occasionally the guy who has to go through literal torture to claim their place in the new world. Of course guys more typically need to fight potentially deadly battles, but that's what guys like to do anyway.
