jin sakai is so queer coded to me like he got bullied for being to "feminine"/different, defied his entire family and threw away traditions, (also was a samurai. if you know you know.) his entire relationship with ryuzo.. is . erm. just the whole subtext of his character and being way more like his mother too.. erm
Hello everyone, if you go to the Morimae Hot Spring and decide to reflect on Ryuzo's death, Jin thinks something along the lines of, "Ryuzo, if you only you were here. You'd brag about how many Mongol heads you took, and crack your stupid jokes..."
I'm interpreting this as bisexually as possible. You can't stop me.
