It was 17 years before the 77th generation. 9 girls that met before made up the 60th generation of understudies-the biggest group ever. When all 9 girls became successors, something amazing happened. After Takamina the 5th became successor, all 9 girls disappeared. No one knew what happened. Until they came back 9 years later-when the 77th generation came.

The lands of the Elemental and the Friendships have been destroyed. Now it's up to ten girls who have to become friends. What will happen to our world? And what will happen to their friendship?
