Actually they only said for a while not couple of years.


 * “It won't be weird for Ise, Kiba, and Akeno to become High-class devils judging from your achievements. But it seems like there are steps even in the world of devils. Especially the higher-ups are noisy about it. They acknowledged the special promotion for you, but they are also saying to follow the proper procedures. That’s why you will become Middle-class devils and be active in that rank for a while. Then soon after you will receive a promotion to become High-class devils from them. You guys can plan about what to do when you become High-class devils during your time as Middle-class devils.”
