Summary
At the Silverman Gym, Machio tells Hibiki and Akemi that the gym is organising a trip to Meat Island for spring break. He also reveals that, excluding Jason, everyone will be going as well. Hibiki and Akemi aren't sure that they can make it until they find out about the Mr. Meat Island contest. Meanwhile, it's revealed that Jason and Deire has the gym under surveillance.

Arriving at Meat Island, the group is enjoying themselves. Machio then arrives with a melon. Deciding to have a melon bash, Machio explains the shrug exercise. Afterwards, Hibiki, Akemi, Ayaka and Gina enter the Miss Meat Island contest. During the contest, Akemi does handstand push-ups. While she's doing this, Machio takes the time to explain push-ups. When it's Hibiki's turn, she displays her punching power. When it's revealed that they're tied in first place, they compete in a bench press battle, which Akemi wins due to Hibiki being too hungry to move.

Later, it's revealed that Jason and Deire are stranded at sea. At the beach, Hibiki and Akemi talk about how much they've grown thanks to their training. Just then, they spot something heading their way. Harnnold meets with everyone and reveals that he rescued Jason and Deire. Afterwards, Hibiki weighs herself. Once she sees the results, she leaves in a very happy mood.
