Kigisu

A man who possesses the divine protection of an assassin and is a senior disciple to Tise. However, he is completely dominated by the murderous impulse of his divine protection and voluntarily leaves the Assassin's Guild. He has now become a mere murderer.

Under the orders of Cardinal Lub, he conducts an investigation on an airship but ends up killing two accompanying investigators on his own and attacks Tise as well.

After a battle with Tise, he is defeated, breaks all the rules of assassins by begging for his life and divulging information on his client, and dies as a result.
