Luna-P

Luna-P (also known as the Luna Ball and Luna Sphere) is a Luna-face-shaped toy carried by Rini, and when first arriving in the 20th Century, she used it to communicate with Sailor Pluto at the Door of Time and Space.

Although used as a communication device, Luna-P was also used to transform into various items at Rini's request. Among a brainwashing umbrella used to trick Serena’s family into thinking she is their cousin, Luna-P was also turned into a baby bottle of "mind control" potion to make the other girls believe she was also Serena's cousin; next taking the form of Grandpa Hino to give the girls the drugged tea.

When Rini became Wicked Lady, Luna-P also received a black Negamoon mark on it's forehead.

Once Rini gains the ability to transform into a Sailor Scout, Luna-P is used less and less.
