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!
Sis too! She won't even
give me a call or send a letter.
هي لا تتّصل أو تبعث رسائل على الإطلاق كالعادة
Also echt! Sie ruft mich weder an
noch schreibt sie mir Briefe.
Y ella no llama ni envía cartas.
Y ella no llama ni envía cartas.
Kyoko ne m’envoie pas de lettres
et ne me téléphone même pas.
E pure lei, che non scrive mai 
e nemmeno si fa sentire per telefono!
Ela também! Ela nem me
liga, nem manda cartas!
Сестра тоже хорошая! 
Ни позвонит, ни напишет.
