A Night Alone Together: Usagi in Danger

A string of break-ins has rattled Usagi's neighborhood, and with her family away she faces the evening by herself. Hearing this, Seiya volunteers to serve as her bodyguard for a single night, casting himself as her protector against the intruder.

The quiet arrangement collapses when Yaten, Taiki, Ami, Rei, Makoto, Minako, Haruka, and Michiru all turn up as well. Chaos erupts once a phage joins the crowded house, since nearly everyone present is frantically trying to conceal that they fight as a Sailor Guardian.

Seiya comes close to confessing his hidden role as Sailor Star Fighter to Usagi, only for Chibi Chibi to cut him off before the words land. The gathered girls, Usagi included, also reveal a shared terror of cockroaches, shrieking whenever one takes flight through the room.

The battle against the Sailor Sommelier plays out amid the confusion of guests ducking into hiding spots to protect their secrets, with Rei and Yaten among those tucked away in the bathroom during the commotion.

The eighteenth episode of the fifth season aired in Japan on August 17, 1996, written by Ryota Yamaguchi and directed by Harume Kosaka. It is a filler installment whose scenes have no counterpart in the manga.

The episode holds the final use of Moon Tiara Action, though it plays only as a gag: lacking a golden tiara in her Eternal form, Sailor Moon simply flings a pizza in its place. A framed photo on Usagi's desk, showing her and Mamoru without Chibiusa, prompts fan speculation about the shifting timeline.
