Kaz: I don't know...the cards appear when I'm about to take a soul, and then in the split second when the soul exits the body I trap it in one of those cards. Then I send it to hell. That's about the best explanation I can give...
Kaz: N-no...I took your soul, but you still have your heart and your body's still working...the only thing that really changes is your morality...you might notice it take a nosedive...
