There is really only one way to describe Robot Girls Z... IT'S SO BAD THAT IT'S ACTUALLY GOOD It's really a comical all girls superhero short with an ecchi twist. The three main characters all fit stereotypical anime roles ranging from happy bubbly yandere to overly eccentric possible tsundere leader to cute likable kuudere (which btw is my favorite) Overall the special is fun to watch, surprisingly entertaining, and really bad, but above all it's so bad that its actually good.
