Sorry, but Chiyo is not the creator of the Puppet technique. :ySasori lost to an apprentice of Tsunade and the inventor of the ninja puppet technique.
Maybe try reading the manga from the beginning, instead of the parts every idiot keeps bitching about every damn time.
Don't complain about the plot, if you don't get it.
