I just hope Issei can evantually control his new form without the after effects he doesn't need a power up anymore just more control with all his forms Vali maybe needs something to compete with Issei like his Lucifer power + Empiero Jugernaut OverDrive i would have never thought that as a option of Vali doing that until i Heard of Issei new powers/form Diablos Dragon
