For Whom is the White Rose? The Moonlight Knight Appears

Makoto is shaken when a Cardian preys on her close friend Shinozaki, forcing her to protect him even after she has given blood and lost much of her strength. Amid the crisis, a mysterious figure who names himself the Moonlight Knight arrives to lend unexpected aid.

A boy's scream interrupts the girls' walk, and Makoto realizes the monster's victim is Shinozaki. Saving her, he tumbles over a cliff and is left bleeding, and at the hospital Makoto donates her own blood when the staff run short of type O. Ail and An feed the stolen energy, gathered by the Cardian named Faraion, into their Doom Tree, coaxing its leaves to bloom.

A flashback reveals why Shinozaki matters so much: after a boyfriend abandoned Makoto in the rain, he appeared with an umbrella and stayed at her side. Meanwhile Usagi's clumsy attempts to jog Mamoru's memory with drawings fail, and Ail, disguised as Seijuuro, tries to win her love with a rose. When Faraion strikes again, a drained Sailor Jupiter cannot finish her attacks, and Mars and Venus are cut down before theirs land. A white rose then falls at the monster's feet, and the Moonlight Knight introduces himself, breaking Faraion's magical wheel before vanishing. Jupiter, rallying at the memory of the harm done to Sailor Moon and Shinozaki, destroys the Cardian with Supreme Thunder.

A recovered Shinozaki leaves the hospital, and Makoto vows to watch over him from afar as he once did for her. The episode marks the debut of the Moonlight Knight. None of its events happened in the manga. Among dub alterations, DiC replaced footage of the bleeding Shinozaki, swapped the flashback's background song, and cut a scene of Ail and An kissing; a Swedish dub was recorded but never aired because the studio could not omit the songs.
