The newest guardian, Sailor Venus, turns out to be a schoolgirl named Minako Aino. Barred by Queen Beryl from killing Tuxedo Mask, Zoisite instead dares him to a duel for the crystals. Usagi trails Mamoru toward the Star Tower after his unexpected kindness leaves her suspicious, and Zoisite ushers the pair straight to the dueling ground. Both men set their crystals down, but Kunzite snatches them away before the match can begin, enraging Mamoru.
Zoisite tries to burn Usagi and Mamoru inside an elevator, defying Beryl's command to spare Tuxedo Mask, which forces Usagi to become Sailor Moon in front of him.

A distraught Usagi begins to cry, and her tears pull the merged Rainbow Crystals together into the Silver Crystal, marking her as the long-sought Moon Princess.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
The episode adapts Act 8 and the opening of Act 9 with several changes. In the manga, Venus arrives as Sailor V and the presumed princess, Kunzite rather than Zoisite lures the guardians to the tower, no one baits Tuxedo Mask into a duel, and Kunzite delivers the mortal wound. The crystal there forms from Sailor Moon's tears alone and only attaches to the Moon Stick during the later fight against Metalia, and the setting is Tokyo Tower.
The DiC dub trimmed the impalement and the pastel montage for younger audiences, and swapped the transformation song Illusionary Silver Crystal for My Only Love, while Mexico's dub swapped in a song titled Resplandeciente Cristal de Plata. Princess Serenity and the Silver Crystal both debut here. This is the only episode in the series to show Mamoru transforming on screen, and the first since episode 2 in which Usagi skips her opening self-introduction.
