They arrive on the scene and Chibimoon explains what happened. Tuxedo Kamen provides the necessary "Ima yo, Sailor Moon" and they all join forces to create the Holy Grail. Chibimoon thinks about the fact that someday she'll be like that and another Holy Grail appears. Chibimoon is astonished, but with the two grails they go Crisis and Chibimoon becomes Super Sailor Chibimoon for the first time. Super Sailor Moon and Super Sailor Chibimoon combine powers to preform Double Rainbow Moon Heartache. The other senshi throw their attacks too, but the Mistress 9 monster just absorbs them. Eventually, Chibimoon's power gives out and she falls to the ground where she is caught by Tuxedo Kamen.
Because nothing else seems to be working, Sailor Moon has the bright idea to go inside the monster and open the Grail. Not surprisingly, none of the senshi are very impressed, but she goes ahead and does it before they can stop her. Mamoru and Chibiusa shriek, but she's already gone.
And then Sailor Saturn appears with some exposition. She whacks the monster with her glaive and the monster feels some serious hurt. Chibimoon wonders that since Sailor Saturn has arrived if their future is now gone -- if her future is gone.
Saturn drops the glaive as everyone expects and the monster is wailed upon and the local area is near destroyed. Tuxedo Kamen protects Chibimoon in his cape, and then everyone turns to look as Super Sailor Moon has made a reappearance. Saturn makes the ultimate sacrifice and goes out the door of time and space with the defeated monster. Super Sailor Moon ascends to Neo Queen Serenity and her power resurrects the people that have died in the conflict and pulls the buildings back together, thus reversing Saturn's destruction.
As the world weaves itself back together again in the wake of such upheaval, the outer senshi find baby Hotaru on the ground and decide to raise her, since she's now alone. They decide to leave to do this. Chibimoon asks if they'll ever see each other again and they all assure her that they will because they love her. Neptune gives Chibimoon the Deep Aqua Mirror as a sign of their promised return, and then they leave.
Usagi, Chibiusa, and the other inner senshi run to Haruka's apartment, but the outer senshi are gone by the time they get there. Chibiusa and Usagi stare into the sky after them, sure that they'll meet again some day.
Here ends the tale of Sailor Saturn and the Death Busters. Chibimoon's story continues in the Dead Moon Circus story.
