Well, I would think the issue with that is a Super Devil is called a Super Devil because it is far above the previous Four Satans, which were considered to be peak of Devil power.

So, if there was a Super Angel, there would need to be some kind of bar to be put againt. Like God or Michael. Michael is/was the Archangel, so I guess any angel strong than Michael would technically be a "Super Archangel" or "Super Angel". Problem is, there isn't one.

It's possible Issei and Irina's son might become a Super Angel, depending on how strong he is.
