beyond vague justifications for her general assholery (i.e. a significant desire for power and a marked bloodthirstiness not shared by anyone else in the game), i want to keep her as a massive bitch because i don't think that being particularly sympathetic would really suit someone of her morality. kumonryu is an "innocent" character and hua is the sympathetic one, so i want to have any details that pertain to sekishusai either serve to show how much of a bitch she is so it's satisfying when she's taken down, or things that maybe do give her a bit more depth (like having genuinely good battle smarts) without going full yakuza and giving her a sad backstory. i think she works better that way (and the villain campaign may just humanise her anyway)
