@Bennia Not insulting Issei or anything but why would Ajuka ask someone who has only been a devil for a little while and has little knowledge of the devil world compared to him who could make good Satans? Ajuka is more than capable of handling that himself.

A Super Devil and a transendental being are one in the same. Super Devils are devils that have strength transecending the bounds of regular devils, even far surpassing Satan. There is no upper limit. Super Devil is just those devils that have passed a certain point. There is nothing beyond that. A Super Devil is a transcendental being. But Super Devil only applies to devils. Transcendental being can apply to anyone. For example, if Dulio eventually gains strength that transcends the bounds of what an angel could be capable of, then he would be a transcendental being.

I really don't see Issei or Rias becoming Satans in the future. If they did that, they wouldn't be able to compete in the Rating Games anymore.
