Because they are the baseline for what is considered "maximum devil potential". Sort of like Vasco Strada, no one would say that that Vasco represents the average human, yet anything stronger than him has to be called "superhuman" as he is seen as the maximum of what the human is capable of. The author specifically points out that Satan-Class devils, as strong as they are, are still considered what a devil is capable of.

That's because Satan-Class is not an actual classification rank, its a power guage based on those with the title, the Satan-Class is basically the peak of the Ultimate-Class Devils, their top peak of the mountain, because in the devil society, its the strongest who rule. That is why bloodline was so important, because it was power. But the Super Devils are in the skies above the peak, transcending bloodline potential into an entirely different class.

That's what you have to see a Super Devil as. Satan-Class is supposed to be as good as it gets, they are the Vasco's of the devil race. But then you have these things that are so strong they can't even be compared to the Satan-Class, an obvious tier above. So strong people question if they are even really devils, or something else.

Yes, that's what I said. Michael is the equivalent of Satan-Class as nothing about him is said to exceed what is expected for "maximum potential of an angel". So just like Satan-Class Devils like Serafall and Falbium are seen as the peak of devil power, Michael is seen as for the angel's power.

However, the question was is there basically "a Sirzecha and Ajuka" for the Angels, is there a Super Angel? What I was suggesting is that they need to set a standard, how strong does an angel have to be to be a Super Angel? Is it simply stronger than Michael? Do they have to be as strong as Sirzechs and Ajuka? After all, Rizevim is a Super Devil, yet no where close to Sirzechs and Ajuka in power.

Of course, age doesn't matter, I never meant to imply that it does. Genetics bring about incredible power in DxD. Hence why those, like Vali, who are descendants of Lucifer are stronger than say a random devil with a random pureblood ancestor. But, if you mix certain genetics, you get a baby jackpot so to speak. Sirzechs was so powerful in part because you mix the magical mastery of Gremory with the incredible magical power of Bael, you get a Devil with the greatest magic potential to master what is probably the strongest demonic power, the Power of Destruction. That's how you get a monster like Sirzechs. Of course, that's not all, because he also was born with unnaturally high demonic power.

He didn't kill the devil kings though. It was specifically stated the Four Great Satans died killing the God of the Bible, meaning that God killed the original four. As far as we know, Michael has no real "feats", but at the very least he was strong enough that Heaven wasn't overrun when God died and the angels lost their means to reproduce normally.

I mean, you can kind of see why Michael of all people needed to pursue peace, because Heaven wasn't really in a position to continue fighting, especially with the emergence of the Super Devils. Sirzechs and Ajuka are not war-mongers, and they use their power to their advantage by pressuring peace. Azazel and Michael were ready to pursue peace anyway, but you can be hella sure they weren't keen on fighting Sirzechs and Ajuka if it came down to it.
