It was a few months after the battle with Galaxia when both Usagi, Rei, Ami, Mako, Minako, Michiru, Haruka, Setsuna, Hotaru, luna and artemis go back to the moon to observe it and protect it, yet guide it like how they did in their past lives

Usagi: So many memories come back here…

Jupiter/Mako: yea

the others laugh until Luna shows up in a hurry

What will happen next?
