Let's Go to the Hot (温泉へ行こう Onsen e iko?) is the 158th chapter of the manga and the first chapter of the Hot Springs Obstacle Course Race Arc. Akane once again comes up lucky in the lotto game and this time wins a trip for two to a hot springs race. The winner of the race gets to go to any hot or cold spring in the world.

Mousse wins a ticket as well and asks Shampoo, but she steals the ticket and asks Ranma to be her partner before Akane gets the chance.
