Duel Project was a challenge issued to Ryuhei Kitamura and Yukihiko Tsutsumi by producer Shinya Kawai during a night of drinking. The challenge was for the two directors to see who could make the best feature film with two principal actors/actresses battling in one principal location in the time span of one week. Kitamura's half was the film "Aragami" with Tsutsumi's being "2LDK".
