>>101309334 (OP)niji had a dude named aster who was trying to fuck all of the new girls as they joined the corpo. Eventually he went too far against Twisty and she reported him to Niji. They did nothing and eventually the whole thing leaked and so they terminated Twisty for leaking instead of the sexpest.
Twisty is a piece of work herself, but Niji's being strung up for not protecting their girls for years.
Also from prior yabs, it's assumed that Aster was far from the only nijimale taking advantage of the girls.
