There's something going on with Kotone, she was either hurt by a man or is a lesbian, wouldn't be judgmental about her... she is more at ease with Mei that's more feminine...
We need Tetsu in drag asap!
NOW Tetsu is starting to call Satori a sister despite knowing is a girl on the inside?!? Well, took him long enough...
I love that he finally started calling Satori his sister, but I also really like the detail of Koto being okay with Mei because Mei is the only one that doesn't identify as a guy. Like, it's cute, her brain registers Mei as a girl immediately (which to be fair, might be because she is canonically girlier than the others, but still)
