I'm pretty sure all of you know the show Powerpuff Girls. Well, there's also an anime adaption of it too, it's called Demashitaa! Powerpuff Girls Z. I just started watching it and it's kinda cute. Of course though, there's some differences. The girls are not sisters, instead they come from different families. Also, unlike in the original show when they 5 year olds and attended kindergarten, they're now 13.
There's other differences of course, such as Professor Utonium now has a son named Ken.
