As seen in this video. Make Gloomy Tira's CE miss (This can done easiest by standing out of range, then using a kick to get hit in the leg) ...then, step to the left or JG to following hits. Finally, grab her during the slow motion frames of her last hit. (possibly with A+G only, but I can't see why it wouldn't work with B+G)[It's far easier to time the grab using JG, but I couldn't do that while recording on my capture card because of a slight delay]
I like the hitsparks, but in this video they can block out some of the animations... but what was I supposed to do..? Use the regular characters or something? Psssh.
Regular characters are DELUDED!!! < . >
