One common trope is the 'coming out' story. The trans character in RWBY fanfiction has to find the right moment to reveal their true identity to their friends or teammates. Another is the 'finding acceptance' trope, where they face initial doubts or even hostility but eventually find a place where they are fully accepted.
It's hard to say. You might need to check with the publisher or look for specific information about the comic's translation status. Sometimes, it could be available in multiple languages, but it varies.
