Onee is a guy who acts like a woman while being a bear. Might or might not crossdress and might or might not be gay.Wtf is a onee??
Yup most of the time when a man uses onee to describe themselves especially how its written in (katakana) .they view themselves as very feminine with what I like to say a good soild 40% chance of them being homosexual you can be feminine without being gayI think it means feminine gay guy but I'm honestly just guessing based on the MC's preference and the small snapshot we got of her past life.
Chatte / meanings and definitions
Female Cat: The literal definition in the Larousse Dictionary is the female of the domestic or wild cat (le chat). However, because it shares a dual slang meaning similar to the English word "pussy," many French speakers avoid using it for pets to prevent vulgar connotations, preferring to just say un chat or specify une chatte with caution.
