Hiroshi Sakiyama (Japanese: 崎山博士) is member of the Mad Angels gang that operates in the New Yokosuka Harbour District. He wears full leather, apparently influenced by a famous movie hero, even though he doesn't own a motorcycle. The other members of the gang look down on Hiroshi for being all show and call him "chicken".
