Six months have passed since Rayne, Hyuga, Angelique and Jade were betrayed by Nyx and watched both him and their mansion burn to the ground. Arcadia is now in ruin, Thanatos is growing stronger, and the Aube Hunters - who have been missing for some time - are now seen as scapegoats for the destruction of the land. With time running out, Arcadia's only hope lies with the now-scorned Aube Hunters and Angelique, the only person capable of saving the land from darkness...
A girl named Asagi Haru works as a maid of the Miyanomori family, which is headed by one of Japan's most powerful magnates. However, the family head suddenly announces that he is retiring, so one of his six sons must assume control of the family.
The fantasy world of Arcadia is in peril: fierce monsters known as Thanatos are sucking the life from humans, and only men known as Purifiers can vanquish them. Angelique is a young girl who attends Melrose Girls Academy and thought her life was normal, until the dashing Nyx told her that she has hidden powers within. After a brutal attack by a Thanatos, Angelique finds she is able to help in the battle and heal those who have been sucked dry; her powers are real, and she discovers she is in fact the Queen's Egg - the only female Purifier. With the help of allies such as shoot-em-up Rayne, the happy traveler J.D. and Silver Knight Hyuga, Angelique will learn about her powers and help put a stop to the Thanatos.
The competition continues as the stars and heavens collide to determine who will open for the Triple S International sporting event. As QUARTET NIGHT and STARISH finish their last act, HEAVENS hijacks the competition, putting the other groups into a flurry of confusion. With a three-way tie, QUARTET NIGHT suggests an idea which propels these three groups to aim for a new stage, leaving HEAVENS with a need for revenge.
After defeating the Spirit of the Sacrea which prevented the newly born Seijuu Universe from developing, Angelique hears that the Queen of Seijuu Universe – the one who maintains the stability of nine Sacrea - has disappeared. Moreover, she cannot go back to her home universe because the dimensional corridor connecting both universes has been destroyed. The Seijuu Universe is still in danger and Angelique is left alone without the support of nine Guardians. What should the Legendary Etoile do to find the Queen and bring her back?
