Tokiwa shows off her athletic skills in a school dodgeball contest. But her gift becomes a curse when she attracts more attention than she can handle.
The story begins when a middle school girl named Yume sees something fall from the sky, and meets a pale violet-colored kitten named Mew. It turns out that Mew has the power of "Yume Synchro" (Dream Synchro), the power to enter dreams. In the dream world, the girl and Mew collect Dream Stones. (Source: ANN)
