Two things I just realized about Elemental Dragon:

Elemental can refer to the elements, but it can also refer to something in its most basic form, without anything added or refined (for example, elementary school). So Primitive and Elemental can both refer to something raw and unrefined, Elemental makes it sound more positive than Primitive does, they convey the same meaning but in a different light. And in a way, that's exactly what Touma did to the story of the dragon, he took the same idea and put it in a more positive light!

The other thing is just that Touma literally made a book which is also what he does as an author.
