But he's not really, he wants to be a manArima-Maria is what in the west would may name a no-binary person, them has dysphoria and that's it.
Arima definitely does, hence the "that's why their similar" line. Taiga's father probably won't for some time I imagine. I also agree with you on the gender side; I also dated a transgender man, and while it's not a universal experience, he was happy playing both male and female parts in theatre, but really enjoyed just being a man with meThis is honestly one of the most satisfying endings to a manga I've ever seen. The only thing I'm left wondering is if Taiga's dad or Arima ever realize(d) who the other was, but I think that's a good thing to leave up in the air. There's also the thing with Arima's gender, but I think it's pretty clear that he's a man. He specifically notes feeling happy getting to be a man around Taiga.
