In which episode does Serena save Rini's mom?

Answer 1

Serena (Usagi in the original Japanese) saves Rini's (Chibiusa in the original Japanese) mom during two separate occasions in the Sailor Moon anime:

• In episode 68 "The Secret of the Luna Sphere" (episode 75, "A Mysterious New Senshi, Sailor Pluto Appears!" in the original Japanese), Serena saves Rini's mom--but inside of Rini's dream. Rini falls ill due to the influence of the Evil Black Crystal and a Droid haunting her nightmares, from her time back in the 30th century, prior to her meeting Serena and the other Scouts. When Sailor Moon and the others defeat the Droid, Rini's dream ends happily, with her mother being "saved," although we never actually see her awaken.
• In episode 81 "Final Battle" (episode 88 "The Final Battle Between Light and Darkness! Love Sworn to the Future"), Sailor Moon attempts to destroy Wiseman, who is destroying the world in the past by opening a massive Dark Gate that would obliterate 30th century Crystal Tokyo from existence. Channeling the power of her future self, Neo-Queen Serenity (and Rini's mom), she and Rini defeat Wiseman and save Crystal Tokyo and the present-day Tokyo from destruction.

Answer 2

She doesn't. It is actually King Endymion in the future that tells Serena (as Sailor Moon) and Tuxedo Mask that they are the future parents of Rini. If Rini knew that Serena/Sailor Moon was her mother at any point prior to the end of the second Sailor Moon season, she did not indicate it.

Answer 3

Rini and Serena are both characters from the popular anime Sailor Moon. Serena finds out Rini is her daughter in episode 76 in the English version, and episode 83 in the Japanese version.

Answer 4

in episode 76 of the English one, the same time darien finds out, i think!?!
