Challenge to Ambition: Chapter 2 (2009)

Ōtani Ryūzō (Ryu Daisuke), leader of the Ōtani-gumi within the Tōdō-gumi, is ousted by Serizawa Daijirō (Kawano Taro), who then becomes the new second-in-command. Under Serizawa, the Tōdō-gumi shifts into an economic organization, aggressively extorting businesses under the pretense of "regional revitalization fees." Even the shop owned by the wife of Mikasa Yūji (Musashi Ken), who is currently in prison, is targeted. Serizawa's relentless pursuit of power plunges Osaka's Minami district into turmoil, igniting a new yakuza war fought over traditional honor and loyalty.
