Fans of the epic series Ranma ½ may need these in their lives. Ranma ½ also has a number of fine doujins here on Doujins that you may also need in your lives.

The online shop Natalie Store has a line of special mugs that change decals depending on temperature. If you're unfamiliar with the series, characters who have taken a dip in the cursed springs on Jusenkyo take on cursed forms when doused with cold water, and can only change back when doused with hot water. The titular character, Saotome Ranma, changes from a black-haired guy into a red-haired girl when doused with cold water. One of Ranma's many suitors, Shampoo, changes from a purple-haired girl into a cat when doused with cold water. Take a look at the mug magic below.
