Episode Summary: Hibiki is a growing girl with a healthy appetite, but when a friend of hers comments on her expanding midsection and overall plumpness, she decides that it’s time to slim down. She joins the Silverman Gym, and discovers that a classmate of hers, Akemi, is planning to join as well. As it turns out, Akemi has a bit of a muscle fetish, and this gym is packed to the gills with bodybuilders and their bulging muscles. Hibiki feels out of place, but decides to try to get her money’s worth anyway.
Akemi is old hat at strength training, but Machio, their personal trainer, is encouraging and helps Hibiki push herself to complete more reps than she might on her own. She learns how to do bench presses and squats during her first week. When Akemi asks how many times a day Hibiki eats, Hibiki gets ready for another scolding, but Akemi is simply impressed; with such a strong appetite, Hibiki has almost infinite potential to bulk up her muscles.
