Ranma 1/2 2 In1 TPB Volume 18

"At a spooky old mansion, girl-type Ranma slips on a banana peel and accidentally uncovers a cursed mirror that makes a love-hungry copy of her who kisses everyone she can get her hands on-including boy-type Ranma! A magical compact can be used to capture the kooky copy, but things take an unexpected turn when Ranma and Akane get trapped inside the compact! Later, Akane wins an enchanted jellyfish bathing suit that finally enables her to swim. But in return for the suit, she must enter a swimming competition. She takes the lead in the race, but a dangerous surprise awaits her at the finish line! For older teen audiences."
