Oneshot. In a world liked ours where dragons have been sealed away, the second world war has broken out. A young man goes to get the last dragnel in order to command it as his dragoneer. But they've actually met once before. No trigger warnings.
What a beautiful one shot uke approached seme as he was kid now he become seme's mate but seme is last male dragon and his mate is also male they cannot produce so with this dragoner will extinct and uke use seme as a weapon to fight off war , nice concept could have been longer but shorter the better.
Great concept, lots of different and interesting ideas, and detailed art. But with so little amount of story it remains a collection of concepts and ideas. In a “WWII like” war, a soldier is able to awaken and use a cursed (and thought of as extinct by many) dragon, whom he rides in order to fight the enemy. When not being ridden the dragon can transform into a man, which is where the Yaoi tag comes into the story.
The main guy is a Nazi!
