The future holds many uncertainties...

Chaos breaks free and takes over the Galaxy Cauldron again while the original senshi are just barely keeping the evil at bay and know that they will loose soon.  As a last resort, they send Sailor Cosmos to the past to find and begin the training of the Neo Senshi.  Little by little, the neo Senshi are brought forward in time, training, but not without being followed by several of Chaos's minions and hordes of nobaka. To the girls, that is hard enough, but the final battle awaits.
