How do you do the F+Fierce -> Kikoshou?

in an old combo video, i saw that Chun Li had Ruby Heart in the corner and did some wierd setup to where she cancelled into Kikoushou and then when the super was over, she was able to dash in and do F+Fierce (mini fireball that goes nowhere lol) -> Kikoushou (QCF+PP) many times. How is this done? I just want to try it out in training mode, thanks!
