Road to the Boss: Gaki Gokudo 3.

Akira Kiyota’s subordinate, Akira Kuroda (Keisuke Kida), works as a hangure (semi-gangster). Watching Kiyota and Kenji succeed as full-fledged yakuza, Kuroda grows increasingly frustrated. After getting into a fight with members of the Kugizaki-gumi, Kuroda is arrested. Kiyota settles the matter, but Kuroda is harshly scolded. Determined to prove himself, Kuroda begs Kiyota to let him officially join the organization. Fellow hangure Shirai (Takuya Shinagawa) also applies, and both are accepted as live-in apprentices of the Washizu-gumi. However, what awaits them is a world far more brutal than they ever imagined…
