Simply the best season of DxD, seeing everyone maturing made me happy but I was impressed by how Issei matured, he's the character who needed it the most and oh boy how he was done properly, the writing is clearly much better than the first two seasons. Only thing I have to complain about is the animation, it has it's weaknesses and I really hope that if there's no season 5 in the works, at least they'll be remade, I am watching the Blu-Ray version but the animation is still pretty bad sometimes, so hopefully it will someday get a remake with much better animation, that'sthe only thing I can honestly complain about for this third season of Highschool DxD.
