Professor Utonium and his son Ken were studying the unknown substance Chemical X. They are trying to make a substance that is more powerful than Chemical X. While they are taking a break, Peach the dog, accidentally drops a rice cake into the Chemical X. A huge chemical reaction occurs, transforming Chemical X into a whole new substance. Professor Utonium decides to name this chemical, Chemical Z. On the same day, a huge iceberg suddenly appeared off the coast of Tokyo City. Ken fires a Chemical Z ray-beam at the iceberg and they dissappear. The Chemical Z beam changes into white and black lights which are released into Tokyo City. Ordinary first-year junior high girls Akatsutsumi Momoko, Gotokuji Miyako, and Matsubara Kaoru are bathed in white lights and they become... the Powerpuff Girls Z!

If you haven't noticed, it's a lot like the Powerpuff Girls in America.
