Not So Fast, Punk

Sailor Pandora and Sailor Vortex for Sailor Moon: Finale, part of the Drifters Saga.

After being released from the statue she had been sealed in for thousands of years, Vortex is assigned to guard one of the few remaining Sailor Senshi against the rising forces of darkness. They seek Pandora's Box, the item that Pandora was put in charge of, to unleash the monsters within.

Of the senshi left, besides Pandora and now Vortex, is the heir the Ginshinzou (I'm pretty sure I spelled that wrong...) Guardian Selene. Vortex doesn't trust him one bit and never lets him anywhere near Pandora.
