Curiosities

 * Kazuki Kitamura and Kenichi Endō have already performed together in 2014 in The Raid 2, as well as Yakuzas: Kenichi Endō as Hideaki Goto, head of Goto Family, a powerful yakuza family from Japan and one of two mob bosses that control Jakarta and Kazuki Kitamura as Ryuichi, the main Goto lieutenant and interpreter.
 * Yuko Oshima, the protagonist of this drama, is a former member from AKB48, one of the biggest groups of J-pop and Japan.
 * Before Isao Tachibana, Kenichi Endō had already been portrayed/interpreted two notorious fictional yakuza bosses in previous films: Joji Yazaki in Crows Zero and Crows Zero 2 and Hideaki Goto in The Raid 2: Berandal. In the first two films, he is the main antagonist, and in The Raid 2 he is a kind of anti-hero / anti-villain.
 * Actors with previous experiences in productions involving Yakuza: Kazuki Kitamura (Dead or Alive (film), Like a Dragon and The Raid 2), Ryo Katsuji (Crows Explode), Tetsushi Tanaka (Get Up! and Outrage Beyond), and Kenichi Endō (Like a Dragon, Crows Zero, Crows Zero 2, The Raid 2: Berandal, Dead or Alive 2: Birds and more).
 * It is possible that Senichi Mizuta, one of the bosses of the Yakuza and one of characters of this series is Zainichi Korean, mainly because he is interpreted by a Korean Zainichi, Kim Sung-Rak. With that it is quite possible that he was inspired by Machii Hisayuki, "The Ginza Tiger" and founder of Toa-kai or Tokutaro Takayama, one of bosses of Aizukotetsu-kai.
