塩沢兼人
Billy and Jimmy Lee (voiced by Hikaru Midorikawa and Kaneto Shiozawa respectively), return to their childhood city, after receiving a letter from their master. The city has changed drastically in the ten years since the Lee brothers left, becoming a haven for street gangs known as Bloody Town after it has fallen under the control of the crime boss Koga Shuko (v.b. Osamu Saka). Shuko is hosting a martial arts tournament in order to recruit new members into his organization, but also to lure the Lee brothers in bringing him one half of the titular Double Dragon medallion, which Shuko is in possession of the other half. Whoever is in possession of both halves of the Double Dragon medallion will acquire unlimited powers.
