This game talks about a legal requirement to be sterilized before trans people can have their gender legally changed. That has just been ruled unconstitutional by the Japanese Supreme Court! Progress! Japan's top court issues landmark transgender rights rulingーNHK WORLD-JAPAN NEWS - YouTube
for reference though, quoting linked article (https://www.reuters.com/world/asia-pacific/japans-top-court-set-rule-sterilisation-requirement-gender-change-2023-10-24/), "a decision by the judges to ask a lower court to deliberate on a separate clause, requiring that the genital organs of people who want to change their gender resemble those of the opposite gender, was met with disappointment."
that said, this is still definitely good news, even if there is room for improvement! thank you for sharing this here.
