A new blue dragon named Sapphie appears and claims to be the lover of Onyx and tries to take revenge on Ryuji. However it turns out that she is not too battle oriented and is forced to retreat. Misaki learns about Rose being a dragon and over in Maruga, the white dragon's home a break in by Onyx occurs. Sapphie later meets up with Rose and they become friends. She teaches her of the Dragon's coming of age ritual, namely a kiss on the dragon mark. Rose and Ryuji perform the rite only to have Rose become extremely conscious of Ryuji's presence (with the mere touch or sight of Ryuji sending waves of heat through her body) which in turn makes Ryuji conscious of her. The couple end up shy and embarrassed around each other to an extreme.
