#13 Final Battle –Reincarnation–
With Usagi and Mamoru’s death, the Legendary Silver Crystal takes its true form before the crystal, Mamoru and Usagi are sucked in by Queen Metalia, injuring Luna in the process. The Sailor Guardians attempt to fight in Usagi’s place but are unable to stop Metalia, who uses the power of the crystal to spread her evil all over Earth. Meanwhile, Luna has Artemis take her to the command crystal to ask for Queen Serenity’s help. Despite the seemingly hopeless situation, the Guardians sense that Usagi is still alive and call upon the power of the holy sword, using their own life force to awaken Usagi, who survived her suicide attempt thanks to Mamoru’s watch. Using the crystal’s power, Usagi breaks free from Metalia’s grasp and is relieved to find Mamoru is still alive. As Usagi struggles to seal Metalia by herself, the spirits of the Four Knights, whose gems had protected Mamoru from the holy sword, inform him of Metalia’s weak point, allowing him to give Usagi the courage to bring out the crystal’s true form, the Moon Stick.

#14 Conclusion and Commencement –Petite Étrangère–
As Usagi tries to use the strength of her heart to overpower Metalia, the power of the other Guardians restores the Crystal Tower on the Moon, which Luna uses to grant Usagi the power of the Moon. Using this power, Usagi manages to destroy Metalia with the Moon Stick, shattering her own transformation brooch in the process, and restoring the Silver Millennium to its former glory. After being awakened by a kiss from Mamoru and learning the fate of her friends, Usagi is summoned by Luna to the Moon, where she is told she will become the new queen. However, Usagi states that she wants to return to living on Earth with her friends and lover, to which Queen Serenity gives her a new transformation brooch, allowing Usagi to become Sailor Moon once more and use Moon Healing Escalation to restore the planet to normal and bring back her friends. As the girls return to their peaceful everyday lives, Usagi and Mamoru’s private time is suddenly interrupted when a pink-haired girl suddenly falls out from a portal in the sky. The girl, who is also named Usagi, points a gun at Usagi, demanding she give her the Legendary Silver Crystal. Source.
