Yuu

A boy who claims to be Vulcan's apprentice. His portrayal differs significantly between the manga and the anime. In the manga, he is saved by Shinra during Miyamoto's disturbance, but in the anime, he meets Vulcan for the first time when he goes to welcome him as a member, albeit later. Although he is fatally wounded by Giovanni, he survives and acts with Special Fire Force Company 8, but is taken over by Giovanni's insect. Later, his brain is completely taken over by the insect, but Arthur manages to kill only Giovanni's insect with fire, allowing him to regain consciousness.
