Sailor Pluto is not the daughter of Chronos in the Sailor Moon canon. Her true identity is Setsuna Meioh, and she is not related to the Greek Titan Chronos in any way.

While she is associated with time and has powers related to it, her connection is to the Space-Time Guardian of the 30th Century. She is a powerful warrior who guards the passage of time, protecting the universe from threats.

The idea that Sailor Pluto is related to Chronos might stem from the fact that both are associated with time and have powerful abilities. However, this connection is not established in the original Sailor Moon manga or anime.
