I read that Vitra Promotion sort of takes the form of Vitra himself, does that mean that the body shape and size is the same as actual dragon or is it the shape and size  of a  humanoid ?

And does Saji's physiology go through dragonification in this form? Meaning that he also Dragon Physiology like Issei.
