Everyone in the Underworld knows who Diehauser and Roygun are. For ExE Issei can scout out potential members from across the world. But why would they leave choosing Satans just for Issei. There are lots of devils who could find candidates for Satan way better than Issei. He doesn't know every devil. He only knows a select few. And in this case, it's Mammon that's a Satan, not Amon. If you're talking about those that could be candidates for the Satans, they wouldn't let someone who's only been a devil for a little while choose. The decision would be left to the people of the Underworld. Ajuka is far more suited to scouting out potential Satan candidates than Issei is. Nothing against Issei but I don't think someone like him should pick Satans. He barely knows any devils. The ones he could think of any devil could think of. Diehauser and Roygun becoming Satans. Well Belphegor and Belial would be included in the 7 Satans and who happens to have those names? Issei being a hero to the Underworld doesn't mean every single matter regarding the Underworld should be left to him. Oh wow, picking Diehauser and Roygun. No one would see something like that coming. Please as soon as people saw that Belial, Belphegor, and Mammon would be included in the 7 Satans, who would people automatically think of who were already Satan-class devils?
