The concept of "crystal hearts" is not a major part of the Sailor Moon canon. Their goal is to protect the Earth from evil, and they often do this by finding and collecting magical artifacts.
However, they are deeply connected to the Silver Crystal, which is the most powerful artifact in the Sailor Moon universe. This crystal, which holds the power of the Moon Princess, is a crucial element in protecting the Earth and fighting against evil.
While they aren't searching for "crystal hearts" specifically, they are involved in protecting and finding powerful magical artifacts, which are essential in their fight against evil.
Here are some points to consider:
* Their role in the story: Sailor Uranus and Neptune are two of the "Outer Senshi," a group of powerful Sailor Guardians who are crucial to the overall story. They are responsible for protecting the Earth alongside the "Inner Senshi" (Sailor Moon and her friends).
* Their connection to the Silver Crystal: Although they are not directly seeking "crystal hearts," they are deeply connected to the Silver Crystal, which plays a pivotal role in the series.
* Their own magical powers: Sailor Uranus and Neptune possess unique and powerful abilities that they use to fight evil. These abilities, like their connection to the Silver Crystal, are essential to their role in the story.
While the concept of "crystal hearts" may not be central to the Sailor Moon universe, it's important to understand that Sailor Uranus and Neptune are powerful warriors who play a crucial role in protecting the Earth from evil and are connected to powerful artifacts like the Silver Crystal.
