I just discovered something while re-reading the spoilers of Volume 20, it is about the name of the new Armor of Issei, "Diabolos Dragon", I noticed that it sounds very similar to the nickname of Aži Dahāka "Diabolism Thousand Dragon".

Also, the name that Rizevim mentioned, when he thought that Issei must be the new transcendental person (Super Devil) called『Dragon Devil King』......That nickname remember me Tannin, a former "Dragon King" and a "Ultimate-Class Devil"...I know that his nickname is Blaze Meteor Dragon...but for some reason when I read the nickname Dragon Devil King, I thought of Tannin.
