Blue Dragon

Shu owns the shadow Blue Dragon, which frequently employs magic sword attacks. In the anime, the Blue Dragon initially refuses to cooperate with Shu until their battle against Ivanov and Gustav, during which Shu acquires sufficient power to control him. For the majority of the series, he is quite insulting toward Shu and constantly criticizes everything Shu does. The Blue Dragon is in fact portrayed as having a very violent personality, and is extremely cold, caring about nothing or anyone but himself.
