Dragon knights. Volume 21 - Mineko Ohkami

After months spent apart, Rath and Cesia have at last been reunited. Since her abduction at the hands of Nadil, Rath has faced all manner of demons, from weakest warrior demon to the mighty Demon Lord himself, all to save the half-demon fortuneteller who, whether he likes it or not, has captured the Dragon Knight's heart. But just because they've been reunited, doesn't mean that they're safe. Rath has been weakened by Nadil's attack and may have to make the ultimate sacrifice if the Dragon Realm is to find victory against the demon horde!
