Akane's Power-Up!

 is the 111th chapter of the manga and the first chapter of the Super Soba Arc.

On New Year's Eve Akane is out arm-wrestling one of the electronic sumo machines, until Shampoo comes along and easily beats her. Akane, tired of losing to Shampoo, asks Ranma to help train her. That night at dinner, Happosai makes a bowl of Super Soba, a soba noodle that will make anyone that eats it incredibly strong. Instead of eating it immediately, Happosai watches a swimsuit contest and Akane eats his noodles.
