First time I saw a trans person getting mad at being called “they” and with gender-neutral terms, wasn't they okay with that????? The fuck??????
I mean Reimu has been making streams with Taiga, Eru and Aki at least once or twice a month, they even call herself "las albinas" because of their white hair (Except Aki, but I remember in a stream she did make her hair white to combine with them). Also, Reimu is in good standing with Meica05, which is the equivalent of being in good standing with Gawr Gura in ES vtubing terms. Basically, Reimu has as an exit escape in case Niji blows and do like Hitler and escape to the LATAM community (metaphorically because she lives in Colombia) with an actual decent reputation in the ES community.
