Eh, I wouldn't call Naoko Takeuchi a TERF, she's not enough of a misandrist femcel to be in the same league as people like Cathy Brennan or the mods and regulars on the Gender Critical sub-reddit.

Keep in mind that Tuxedo Mask becoming increasingly useless with each passing story arc was mostly an anime thing. He was pretty based in the manga.
