While that's all nice and dandy, I was talking about what their appearance would be in 30 years. Not their breasts because it's obvious they are all going to have big breasts when they;re older considering that we've seen Koneko in Shirone Mode, Asia is still growing, Le Fay is still growing, and Kunou is still young. Rias, Akeno, Kuroka, and Rossweisse already have enormous breasts. I was talking about the fact that devils can change their appearance to their liking, Which is why Okita Souji and Macgregor Mathers having the appearance of being in their late 20s despite them not even being 200 yet. While Sirzechs and Grayfia look like they are on their early 20s despite being like 500 years old. That's an estimate based on the evil pieces system being created and Lord Gremory's bishop, Heinrich Cornelius Aggrippa(A real life guy. Look him up and see how old he is).
