Blue Seed

Blue Seed (碧奇魂 ブルー シード, Aokushimitama Burū Shīdo?) is a Japanese manga written and illustrated by Yuzo Takada. It was animated for broadcast on TV Tokyo in 1994.

The story is based on the Izumo cycle of Japanese mythology and the tale of the god Susanoo and the eight-headed monster Yamata no Orochi. The main character, Momiji Fujimiya, is a descendant of the mythical Princess Kushinada (奇稲田姫, Kushinada-hime?). When Japan is menaced by Aragami (荒神, Aragami?, lit. "angry gods") spawned by Yamato-no-Orochi, Momiji is intended to be sacrificed to appease the Aragami. She instead, however, becomes a member of the Terrestrial Administration Center (TAC), a secret agency charged with fighting them.

The series ran for 26 episodes, originally airing in Japan from 5 October 1994 to 29 March 1995. An OVA, "Blue Seed Beyond", was made in 1996. The anime is licensed by ADV Films in the U.S.
