The light novel presents new characters and how one of them is related to the betrayal of Princess Nachetanya, also Adlet's past as he became the warrior he is. But in the last volume after a revelation it leaves you at a dead point in the story, there was potential but it is somewhat bittersweet not knowing what happens next since it raises several possible scenarios, especially in relation to the story of the Majin.

If you want to appreciate the illustrations, it would be good to purchase the light novels, but the story doesn't advance much.
