Duo Lon

Duo Lon (Hánzi: 堕瓏; Pinyin: Duò Lóng; Japanese: デュオロン Duo Ron) is a member of the assassin group, the Flying Brigands (known as the Hizoku (飛賊, Hizoku) clan in Japanese), and the half-brother to Xiao Lon. As the son of the clan's leader, he is known as a "prince" and is the eldest of Ron's sons. Like his brothers, he left the village in his youth to train and perfect his art. His overall look was based on the title character from the anime Vampire Hunter D. His official nickname is The Silent Assassin (静か なる 暗殺者, Shizuka naru Ansatsusha).

Personality
In spite of being a Hizoku assassin, Duo Lon is calm and has a good heart. He also has a strict sense of justice, as shown when he turned on Ash and by his mission to kill his own father. He feels estranged from his father and often does not address him as his parent, preferring to call him "that man" or "Ron". Although he considers Luan his good friend from childhood, their relationship became strained with Ron's betrayal.
