Aragami: Raging God of Battle (2003)

Ryûhei Kitamura did a fine job with his half of the Duel Project, shot in just one week. His stamp is evident in almost every scene, so it becomes apparent pretty quickly that things aren't quite what they seem.
The setting is a secluded temple decorated with rich purples and reds that give it a strange allure. The characters sit opposite each other, sizing the other up repeatedly. There's some light barroom philosophy throughout to keep the pace before the aggressive conclusion.
It's short but just long enough; ten minutes more and it might've begun to overstay its welcome. Fans of the director's earlier works will have more fun with the ending than newbies will.
