Usagi gains a couple of pounds and starts to obsess about her weight. Jadeite starts a health club to drain energy out of people through a dubious advertising campaign and strange methods. Weak from not eating since the night before, Usagi is about to pass out when Motoki Furuhata, a video arcade who works at the Crown Game Center, finds her and offers to help. Usagi and her friends sign up after seeing how much weight Ms. Haruna has lost. Luna suspects that Miss. Haruna Sakurada has fallen victim to the enemy and tries to convince a resigned Usagi to transform and help her. Usagi discovers tanks in the basement which are sucking the life energy out of her friends. (Source: Wikipedia)
