"Act 9 Serenity - Princess - " is the 9th chapter of the Pretty Soldier Sailor Moon manga series and the 9th chapter of the Dark Kingdom arc. It was written and illustrated by Naoko Takeuchi.


Sailor Moon is revealed to be the true Moon Princess, Princess Serenity, and begins to remember her past life as the Princess of the Moon during the time of Silver Millennium, as well as Tuxedo Mask, who is revealed to be Prince Endymion, the Prince of Earth during the time of the Silver Millennium.


As Sailor Moon holds an injured Tuxedo Mask, calling out to him, he begins to remember his past life as prince of Earth. He realizes that he use to be Prince Endymion and Sailor Moon was his beloved girlfriend and sweetheart, Princess Serenity. He calls Sailor Moon Serenity and losses conscious. Sailor Moon screams in anguish and her tiara shatters, only to be replaced with a crescent moon symbol on her forehead and transforms into Princess Serenity. Sailor V's moon symbol vanishes and is replaced by the Venus symbol, becoming Sailor Venus. Mamoru's pocket watch appears and as it winds backwards, Serenity and the Senshi begin to regain their memories of their past life.

Serenity remembers how she and Endymion entered into a forbidden relationship, which leads to war and their deaths. Serenity cries and a teardrop turns into the Legendary Silver Crystal. Metalia feels the crystal's power, saying it is giving her strength. Meanwhile, Kunzite begins to remember his past. He and the other Shitennou use to be Endymion's bodyguards until they were brainwashed to fight against the moon. When they were reborn, they were captured and manipulated again into fighting for the Dark Kingdom. A light leaves the Silver Crystal and enters into Tuxedo Mask's body. Kunzite captures Tuxedo Mask and transports to the Dark Kingdom. Sailor Venus comforts a distressed Serenity, telling her that she is the leader of the Senshi and it was their job to act as Serenity's guardians. Luna also mentions that Sailor Venus was to act as a decoy princess while Sailor Moon was developing her skills. The next day, the girls plan to try and save Mamoru, but before then, they need more information on the Dark Kingdom and the Silver Crystal. Luna says that to gain more information, they will be going to the moon.
