Shoko is a student at Ryuusei Private Academy Middle School. Her dear sister, Kyoko, had went to study abroad five years ago and hasn’t heard from her since. One day, an unknown entity suddenly attacks Shoko. The ones who attacked her had been the Dryads, underlings of the evil goddess, Eris, who was once sealed by Goddess Athena. When Shoko and Saori Kido awaiting the Galaxian Wars meet, the gears of destiny begin to turn!
Come, now is the time to 
awaken as Mother's host!
!هيّا، الآن حان وقت الاستيقاظ على هيئة مضيفة والدتنا
Los! Nun kannst du
Mutter als Gefäß dienen!
¡Es el momento de que despiertes
como recipiente para nuestra madre!
¡Es hora de que despiertes
como recipiente para Madre!
Le moment est venu de t’éveiller,
hôte de notre mère !
Forza, è il momento di risvegliarti
in quanto corpo ospite della Madre!
Vamos, é hora de despertar
como hospedeira de nossa mãe!
Да, настал твой час
пробудиться как сосуд Матушки!
