Athletes compete for a place in the World Finals.

يلتقي سبّاح تنافسيّ مصادفةً بصديقة الطفولة، التي أصبحت نجمة رفع أثقال صاعدة، ويكتشف أنّها تمتلك مشاعر حبّ مكنونة تجاه قريبه.

Hibiki Sakura is your average high school girl, with a voracious appetite. Noticing her clothes tightening in lieu of her slowly expanding waistline she decides to look into enrolling in the nearby gym. There she runs into a girl from her grade named Souryuuin Akemi.

Akemi, who has a muscle fetish tries to get Hibiki to enroll in the gym despite its high ratio of macho men. Thankfully a beautiful trainer, Machio, appears and unknowingly convinces her to enroll and start her quest to a great body.
