Pretty Guardian Sailor Moon Eternal the Movie Part 2

A girl named Hotaru, cared for by the Outer Sailor Guardians, begins to age far faster than she should. No one around her can say why, and the time comes for every Sailor Guardian to gather again, Usagi (Kotono Mitsuishi) and Chibiusa (Misato Fukuen) among them. Chiaki Kon's film keeps coming back to the same plain idea: the people you fight beside are the ones who decide what you can survive.
