# Ao no Fūin

Ao no Fūin (蒼の封印, literally "Blue Seal") is a Japanese shōjo manga series by Chie Shinohara which was serialized in the manga magazine Shōjo Comic from issue 22 in 1991 until 1994. The story is about a beautiful high school girl, Sōko Kiryū, who finds out she is the latest reincarnation of Sōryū (usually called "Seiryū"), the demon queen who once ruled the earth with her demon armies. Unfortunately, she has fallen in love with a boy named Akira who is the reincarnation of Byakko, the legendary white tiger who is destined to kill her.
The story is loosely based on the tale of Four Gods in oriental cultures, namely the Azure Dragon (east), the White Tiger (west), the Black Turtle (north) and the Red Phoenix (south). Ao no Fūin was adapted into a CD drama in 1993 and three novels by Natsumi Yamamoto in 1998.

## Plot

The story is set in modern Japan. Sōko Kiryū is a beautiful first year transfer student in high school, having just moved into the area. Due to her uneasiness over the move, she has developed dizziness and fainting spells. Shortly after she transfers into the new school, she somehow causes a would-be rapist who attacks her in the infirmary to simply vanish, leaving his clothes on the floor.
About this time, a boy named Akira, later known as Byakko, appears at the school and begins pursuing her. He tells her that he is Byakko, the White Tiger of the West, and that he will kill her because she is the clone of the Demon Queen Soryū. With growing a horn, remembering a hunger for humans, and exhibiting unusual powers, Sōko is forced to accept that she is an oni even though she denies it. However, due to her growing feelings of love for Akira and her desire to become human, Sōko is determined to fight against this ill fate.
