There's quite a lack of details here so allow me to explain:
Linca Tojou, a VTuber from Matsudo, in the Chiba prefecture, collaborated with the local police department, out of love for her city, to release a video starring her in which she gives tips to kids on road safety (bike safety to be more precise, in Japan using the bicycle for everything is very common). These sort of collabs are pretty popular in Japan as VTubers have the same charisma as mascot costumes.
However, the AFER, a Japanese feminist organization, sent an "open letter" to the police department accusing them of posting an inappropriate video because the VTuber's design in question was apparently too risqué for them (mainly her midriff being visible, her skirt being "too short" and the jiggle physics, so "muh sexualixed underaged girls"), and the video got taken down. While the police department justified the take down of the video under the pretense of people having missed the point on it being a PSA (because of the drama obviously), it was obviously because of the backlash the VTuber was receiving, something they wanted to avoid at all costs.
Anyways, no trips to any town halls, it was just an open letter and the AFER got so much backlash for it online they tried to backtrack and say that they did NOT ask the Chiba police to take down the video but, well, the intent was absolute there.
Not much else happened to the VTuber as much as I know, she's still in good terms with the local police and pretty sure this drama helped push her career.
You can even watch the video in question on YT still.

If this screenshot I fished out of Twitter is legit, allegedly she's "mixed Japanese". Judging by this picture and the photo in her diploma, I don't know, her eyeshape does incline for it to be true, but she's also definitely got a lot of white in her.
