In a modern magical world, Dragon Sages are the highest-ranked spellcasters who are known for their vast knowledge in magecraft. Their unique ability to turn humans with mystical blood into powerful dragons is to be feared by anyone.

However, it is quite different for Ulysses Corasell, as he was only promoted into a Dragon Sage because of pure pity. To make everything worse, he discovers that his dragonoid partner; Yehanna Lancelot, is an assassin who's out to kill his fellow Dragon Sages out of revenge.

Now as an unwilling participant of his partner's schemes, Ulysses will embark on a perilous journey that only destruction and death await.
