Dragon Crisis!

The protagonist of the series is Ryji Kisaragi, an apparently unremarkable adolescent who leads a tranquil existence while going to high school. However, as his second cousin Eriko arrives from abroad, his tranquil life is disturbed. Eriko brings Ryji to FANG, a black marketing organization, without more delay. They rob the broker of a sizable relic box and flee. Eriko and Ryji discover a young dragon with long blonde hair and beautiful blue eyes after opening the package. The girl recognizes Ryji right away and is drawn to him. Due to the rose-like pattern on the girl's left hand, they decide to call her Rose. The group that had been holding Rose captive suddenly shows up to take her back. However, Ryji is not to give up without a fight!
