Iirc, during the Silver Millennium the Prince of Uranus was in love with the Princess of Neptune. When his sister, Sailor Uranus, was killed in battle, he took her place so he could fight alongside his lady love. After Beryl slaughtered the senshi and Queen Serenity made her wish for the senshi to be reborn on Earth in the modern era, it was the Prince of Uranus' soul that was reborn, but in his sister' body.
Tldr; was a trap in her past life, now a reverse trap.
I was a massive moonie faggot back in the late 90s - early 2000s, so my brain is full of useless bullshit trivia like this.
