Hideo is a down-on-his-luck mangaka who found work as an assistant after his own series was cancelled due to poor sales. He comes across as fairly timid and insecure, but often has spurs of confidence. He suffers from delusions and is very anxious, especially when in the dark. Despite Japan's strict laws on firearms, he owns a shotgun to which he has a license. This makes him a very desirable person to hang around with following the outbreak, but Hideo is very serious when it comes to the law and won't allow anyone else to even touch his gun.
