Perfect Couple

Perfect Couple is the fifth episode of Sailor Moon Super S. It was preceded by Baiting The Trap and followed by Much Ado About Kitten.

Plot
Darien introduces Serena and Rini to his old college friends Saori and Kobayashi. Rini realizes that Saori is in love with Darien.

Saori is the next target of the Amazon Trio. Tiger's Eye walks up to her, speaking with a French accent and saying he is looking for his tour guide. However, she meets up with Darien instead, putting images in Rini's head of him dumping Serena for her, which would erase Rini from existence. She tells Koby, who is in love with Saori, to tell her that he loves her. She then informs Serena about Darien and Saori.

Tiger's Eye traps Saori and extracts her dream mirror. As he looks into her dreams, Serena and Rini arrive and transform into Sailor Moon and Sailor Mini Moon. Tiger's Eye doesn't find Pegasus in Saori's dreams, and summons a Remless named Puko, who has the appearance of a balloon, to deal with Sailor Moon. Puko begins to suffocate Sailor Mini Moon, but Sailor Moon stops her, so she goes after Darien, but Sailor Moon jumps in front of him and Puko nearly suffocates her. Darien stabs Puko with a knife, deflating her to a humanoid form. Sailor Mini Moon summons Pegasus with Crystal Twinkle Bell, and Sailor Moon destroys Puko with Moon Gorgeous Meditation.

Saori realizes that Darien is in love with Sailor Moon, and falls in love with Koby instead.
