This week’s episode is: Usagi Will Teach You! The Way to Get Slim.
Usagi ends up quite distressed when she finds out she has gained weight. The cure? Dieting and exercising at a new fitness place with her classmates. Haruna-sensei has already been going there, and Usagi and Naru make Umino spill the beans on it’s location. Unfortunately, this is yet another plot to get more energy from humans by Jadeite and the Dark Kingdom. Usagi ends up in a bubble bath while her friends get their energy zapped. Usagi is still so exhausted that she ends up fainting in Mokoti’s arms. After feeding her, he gives her encouragement that chubby girls are cuter, but that is immediately dashed by Mamoru. Usagi goes back to the fitness place, but is interrupted by Luna, who has been sneaking around and overheard Jadeite saying that Haruna-sensei is almost used up and will die soon – and Haruna-sensei is being drained as we speak. Usagi transforms to Sailor Moon. Jadeite sends some fitness guys after her. Usagi gains courage when Luna tells her that fighting will help her loose weight. The guys are being controlled by head bands, though, and Usagi breaks them with her tiara. Everything once again goes back to normal. Including Usagi still being upset about gaining weight.
