Hiroyuki Ninomiya/Gaku Hamada (29-year-old) is a construction consultant who has set up a small office in Osaka’s Nishi Shinsaibashi. Although his title is construction consultant, he is actually a broker who uses other yakuza like the Kobe organised crime group, Nichoukai, to suppress yakuza that come to threaten and disturb construction sites. After the Act for the Prevention of Wrongful Acts by Members of Organised Crime Groups went into force, the number of such cases have dropped. Ninomiya’s life has suffered and he even has to dabble in consumer finance. He is not particularly smart, good at fights or fashionable.
