A pilot film for Mamoru Oshii's television series of the same name, which was cancelled while in production. The Fullmoon Tradition: Indra combines sci-fi ideas with Hindu mythology, creating an interesting hybrid about a group of adventurers led by Shudra, a descendant of the military goddess Indra. They journey to the "Moon Gate" in order to purify their home world of Purusha. The pilot shows a battle with a hydra, plus various conflicts and interactions.
