Shu is the owner of the shadow Blue Dragon, which often uses magic sword attacks. In the anime, Blue Dragon at first doesn't cooperate with Shu until their fight with Ivanov and Gustav when Shu managed to gain enough power to control him. For most of the anime, he is quite insulting towards him and constantly criticizes everything Shu does. The Blue Dragon is in fact depicted as having very violent personality, and is extremely cold, not caring about anything or anyone but himself. (Source: Wikipedia)
OVER is the ruthless third member of "Four Heavenly Kings", the four elite members of Tsuru Tsurulina IV's Hair Hunting corp.

This harshness for his job includes the treatment of his own teammates, as seen by his scalping of both Gunkan and Kitty Poo after their failures against Bo-bobo and the Hajike rebels. Although OVER can and will attack with little or no notice, he mostly controls his hair hunting activities from an ancient Japanese castle, where he controls a platoon of various ninja-like warriors including The Five Hidden Killers (dub: The Ultimate Five Assassins), who themselves are known for their stealth and abilities. He has noticeably long white hair and eyebrows with pointy ears and long chin. He wears a short black jacket that reveals his chest and white pants.
