All the signs were send to earth and live a normal live like other people. Till they know they're actually stars, and have to start war. Just like every other story haha
This is book 1
The seven deadly sins(No,not the anime guys) escape from the infernal regions and attack the Zodiac signs in an effort to bring about the destruction of the world.
The Zodiacs can't have that so conflict insues.Read to find out what happens.
P.S:This is more of a collection of ideas and plot summary for a movie than an actual book.Figured I should mention that rather than have you open and be disappointed.Aren't I a nice guy?
