What gods, the god we seen in that animé torments her all the time and she thinks he's a cunt for that.
In the manga Being X is depicted as a council of several gods, so I am guessing the original poster was referencing this particular aspect. But regardless which interpretation of Being X we take (each version is different, from the light novels, to the manga, to the anime), he does make Tanya ridiculously overpowered, so the point of her having his favour stands (his own less-than-benevolent motives notwithstanding).
